Title: Improvements relating to a spring suspension for perambulators and other light vehicles
Inventor: MOULTON ALEXANDER ERIC
IPC: B62B9/18
Filed: 1950-03-22
Abstract: 680,473. Spring suspensions; preventing lateral canting. SPENCER, MOULTON & CO., Ltd., G. June 13, 1951 [March 22, 1950], No. 7151/50. Class 108 (ii). In a spring suspension for perambulators and light vehicles, the stub axle of each wheel is carried by a wheel bearing arm, connected to the chassis or body of the vehicle through the medium of a rubber torsional shear bush and the stub axles of transversely aligned wheels are directly connected by an antiroll bar or tube to afford lateral stability. In the arrangement shown, in which each wheel is carried by a bearing arm 7 and a torsional rubber shear spring 8 preferably of the type disclosed in Specification 676,098, the aligned wheels of each pair are directly connected transversely of the perambulator by an antiroll bar 10, the outer extremities of which project through a rubber lined eye 11 of each arm 7 and form stub axles for wheels. Inner metal shells 13 of the springs 8 are secured to brackets 14 or to clamps 15 which are welded to side frames of the perambulators so that the arms 7 are located below the frames. Limited independent movement of the wheels is permitted by bending of the bar 10. The antiroll bar may be of square section. Also, the anti-roll bar may be a " live " axle and run in oil bearings. Specification 616,056 also is referred to.

Title: Improvements in Fluid Control Apparatus for Turbines and the like.
IPC: F01D17/00
Filed: 1918-04-29
Abstract: 116,271. Westinghouse Electric & Manufacturing Co., (Assignees of Johnson, J. F.). May 31, 1917, [Convention date]. Centrifugal governors; fluid governors.-Relates to mechanism for controlling the delivery of fluid through at least two valves, for example the low and high pressure fluid valves 6, 17 of a mixedpressure turbine, the mechanism being adapted to operate independently of the turbine governor 4 in opening the high-pressure valve 17 when the low-pressure supply fails or is insufficient to carry the load. The low-pressure valve 6 moves in response to pressure variations in the fluid supply, and its stem 16 contacts with a block 33 on a yoke 30 actuated by the governor 4 through an oil relay 27. A lever 35 connects the stem 16 to a link 38 on the stem 24 of the high-pressure valve 17, and a short link 39 connects the lever 35 with a lever 34, which at one end is pivoted to the block 33 and at the other end has a slotted connexion with a fixed pin 36. As the load increases, the governor 4 raises the block 33 and allows the valve 6 to be opened by the excess fluid pressure below it; the levers 34, 35 remain parallel until the valve 6 reaches its upward limit, when the continued upward movement of the block 33 immediately causes the valve 17 to open, and the governing function is transferred to the valve 17. A closing movement of the valve 6, due to a decrease in the low-pressure supply, also imparts an opening movement to the valve 17, the lever 35 turning on the fulcrum 39. So long as the block 33 and the stem 16 move in synchronism, the valve 17 is unaffected by variations in the position of the governing mechanism.

Abstract: 727,962. Reservoir pens. MENTMORE MANUFACTURING CO., Ltd. March 15,1951 [March 22, 1950], No. 7193/50. Class 146(3). Leakage of ink from the reservoir of a ball-point pen is prevented by providing a partition within the reservoir above the ink meniscus comprising a flexible member of elastic material formed with at least one aperture the walls of which are normally pressed closely upon each other under the action of the elasticity of the material of which the member is composed. The ink reservoir may be of cap. illary or non-capillary dimensions. As shown in Fig. 1, the reservoir tube 1 has a non- capillary bore in which is fitted, at a short distance from the open end 2, a tubular element 3 having a capillary bore. A plug 6 having an air-intake 10 is fitted into the open end of the reservoir, and has a reduced portion 7 over which fits a conical, &c. cap 8 of elastic material, such as rubber or plastic. The cap 8, at its apex, is formed with a rectilinear or curvilinear slit 9 the opposed walls of which normally press closely upon each other, but which allow replacement air to enter the reservoir. Several slits may be present, arranged in various ways. In the form shown in Fig. 7, instead of slits, a number of fine perforations 9a are distributed over the conical end of the cap 8, and are formed by piercing the wall of the cap with a fine point so that the walls of the perforations will close together as the point is removed. The flexible cap, Fig. 10, may be formed by moulding and comprises a cylindrical portion 8a merging into a flat end 8c along the length of which is formed a narrow slit 9. The conical flexible cap could be mounted directly in the open end of the reservoir, thus obviating the plug 6, by forming it with an extended tubular skirt which is rolled over the edge 2 of the reservoir. Specification 706,314 is referred to.

Title: Improvements in or relating to methods for the production of knitted work by means of flat hand knitting apparatus and a flat hand knitting apparatus for this method
IPC: D04B39/00
Filed: 1955-03-15
Abstract: 798,377. Knitting-machines. STEINHOF, K., [trading as STEINHOF, K. [Firm of]]. March 15, 1955 [May 14, 1954; Sept. 9, 1954], No. 7490/55. Drawings to Specification. Class 74 (2). A hand operated flat knitting-machine comprises main and auxiliary needle beds disposed approximately at right-angles to each other and with each needle of the auxiliary bed directly opposite a needle of the main bed. In producing a fabric plain knitting is commenced on the needles of the main bed which are operated by the usual stitch cams. Subsequently, to produce 1 x 1 rib knitting, alternate needles of the main bed are withdrawn from operation and their loops transferred to the corresponding needles of the auxiliary bed. Knitting continues by operating the cam locks of each bed separately, such that the needles of the main bed first draw loops and knit with the result that a length of yarn extends from each loop to the next around and in the hook of each needle of the auxiliary bed. These needles which have previously cleared their transferred loops are then caused to knit the length of yarn by drawing it through the cleared loops as the auxiliary cam lock moves along the bed in one direction. The auxiliary cam lock is then moved back in the reverse direction to cause the needles to clear their loops prior to the knitting of the next course which commences by knitting on the main needles first. If tuck loops are to be formed in the fabric by the auxiliary needles, the reverse movement of the auxiliary cam lock is deferred until the yarn has been fed and knitted by the main needles for the next course which also involves feeding the yarn into the hooks of the auxiliary needles. When the auxiliary cam lock is returned to its initial position it, therefore, clears the previously knitted loops and the yarn last fed into the hooks of the auxiliary needles. A third course is then knitted by the main needles and subsequently by the auxiliary needles such that their loops are drawn through the previously knitted and also around the length of yarn extending round the shanks of these needles thereby to form tuck loops. The needle beds are mounted on brackets, the auxiliary bed being adapted to be clipped in position in relation to the main bed. Specification 764,527 is referred to.

Title: Improvements in or relating to apparatus for placing a pick-up on a record at a pre-selected position
IPC: G11B3/095
Filed: 1948-03-11
Abstract: 635,673. Supporting gramophone pick-ups. DECCA RECORD CO., Ltd., COURTIS, A. W., and HALLETT, K. G. March 11, 1948, No. 7525. [Class 40 (ii)] For placing a pick-up on a rotating record at any pre-selected position, an indicating device shows the position in a direction transverse to the direction of travel of the record and means are provided actuated by the rotating record or drive for lowering the pick-up on to the record when the latter is in a pre-selected angular position. The pick-up arm 13 rotates about the vertical shaft 12 and drives a pointer 17 over a scale 18 through a step-up gearing 15, 16. The arm 13 also rotates about a horizontal shaft and carries at its end, remote from the pick-up, a magnet coil 19 which co-operates with an armature 20 mounted on the shaft 12. The normal magnet energizing current is insufficient to lift the pick-up off the record but will retain it in the raised position if placed there. A cam on the driving spindle 11 of turntable 10 operates a change-over switch for a short period once per revolution of the spindle. The circuit for energizing the magnet 30, Fig. 2, comprises a resistance 32, a resistance 33 and alternative paths through a normally closed " drop " push-button 34 or the lower contacts of the cam-operated switch 35. A " lift " push-button 36, normally open, and the normally open upper contacts of switch 35 are connected in series across resistance 33. If the pick-up is in the raised position, and the " drop " button is operated, the circuit of the solenoid is broken when the cam operates the switch 35 to open its lower contacts so that the pick-up is lowered at a definite angular position of the record. Similarly, operation of the " lift " button 36 when the pick-up is on the record allows resistance 33 to be short-circuited when the cam operates switch 35, to increase the current through magnet 30 to such a value that the pick-up is lifted off the record. In order to be able to repeat settings, the record is marked on the periphery and the mark is registered with a mark or one of four marks, for example, 90 degrees apart on the turntable. The latter arrangement allows a more accurate adjustment to be made. For adjusting the pick-up arm to a selected indicator reading the disc armature 20 is rotated by a friction drive knob 22 and felt bush 23. The cam-operated switch may be replaced by a relay controlled by a photo-cell responsive to a mark on the record or turntable.

Abstract: 746,763. Making boots &c. GAMBA, V. L., and BRENNA, J. J. March 18, 1954 [March 18, 1953; July 31, 1953], Nos. 7531/53 and 21321/53. Class 17 (2). In making ballet shoes wherein the toe part of the upper extends in pleats to meet the sole, both sides of the margin of the upper are coated with adhesive, such as rubber solution, so that the pleats can be stuck in position without the use of tacks. As shown, in making a ballet shoe on the turn shoe process an outsole 25 is tacked in position to a last and solutioned, and an upper 12, in three parts, with a lining 13, in two parts joined by central seams 17, is placed over the last. The upper 12 extends beyond the lining at the toe and the whole of its inner face and the margin of its outer face has adhesive applied. The heel and side parts of the upper are lasted and stuck to the sole and the centre of the toe is then likewise stuck to the sole, after which the pleats 29 are formed and stuck in position by the adhesive on both sides of the upper. A lining piece 30 is stuck over the toe part at least and the shoe is completed by the usual turn process. In a modification, the invention is applied to a normal cement lasting process in which an insole is used and the upper is lasted right side out.

Abstract: 563,009. Fluid-pressure servomotors. ESCHER WYSS MASCHINENFABRIKEN AKT.-GES. June S, 1942, No. 7782. Convention date, July 5, 1941. [Class 135] [Also in Group XXXIII] A hand lever 41 connected to the throttle valve 45 of an aircraft engine and to the spring 3<1> of an engine-driven centrifugal governor 11, such as is described in Specification 541,839, is adjustable in a slotted plate 50, the movement of the lever in the middle slot 47 altering the throttle opening and allowing the pitch of the propeller blades to be varied within a predetermined range by means of a device 5 controlled by the governor 11 and the movement of the lever from the end of the slot 47 at which the throttle valve 45 is least open through a slot 51 to slots 48, 49 rendering the governor I inoperative and admitting pressure medium to the device 5 to move the propeller blades outside their normal range of adjustment into the braking or feathering positions respectively. Pawls 53, 56 prevent the lever from being moved directly from the slot 51 to the slot 47 and from the slot 47 to the slot 49 respectively so that before the lever can be moved from the slot 49 into the braking or feathering slots 48, 49, the governor 11 is set to act at a lower speed and before the lever can be restored to the slot 47 movement of the propeller blades towards the high pitch position is initiated. The lever is mounted on a shaft 42 carrying a change-over valve 8 which when the lever is in the slot 47 connects pipes 6, 7 leading to the device 5 to pipes 9, 10 to allow the flow of oil from the lubricant pump 12 under the control of the governor valve 4, The valve 8 also connects a pipe 18 leading from a second oil pump 17 to a pipe 24 connected to the engine casing. When the lever is in the slot 48, the valve 8 is displaced to break the connection of the pipes 6, 7 with the pipes 9, 10 and to connect them with the pipes 18, 24 to cause the blades to move to the braking position. When the lever is in the slot 49, the connections of the pipes 6, 7 with the pipes 18, 24 are reversed and the blades move to the feathering position.

Abstract: 725,188. Electrical tests. GENERAL ELECTRIC CO. March 23, 1953 [March 26, 1952], No. 7914/53. Class 37. In a method of measuring magnetic properties of magnetic materials by magnetizing a specimen with a time-varying flux having a component parallel to the surface of the specimen, the voltage V1 along the surface of the specimen in a direction perpendicular to the direction of the flux component is applied via pointed conductors 16, 17 to a measuring instrument of high input impedance to give a reading representative of the rate of change of flux through the cross-section measured. The testing apparatus, Fig. 5, includes a pair of laminated legs 23, 24, bent over to form an air gap and carrying a coil 27, in which a voltage V2 representative of the time-rate of change of intensity in the specimen is induced. The voltages may be applied to a wattmeter via amplifier circuit arrangements, Fig. 4 (not shown), wherein the amplifier for the voltage V2 includes an integrating circuit so that the power loss due to hysteresis, J HdB, may be indicated. In a modified application of the apparatus, Fig. 5, the specimen 19 is magnetized by applying a generator 86, Fig. 6, to the coil 27 and in this case the coil current is representative of the field intensity H. In this case, however, the reluctance of the arms is more critical and the application is limited tc measuring relative power losses. An arrange. ment for displaying the hysteresis loop by applying the two voltages, after integration, to the horizontal and vertical plates of an oscilloscope is described with reference to Fig. 7 (not shown) and in a further arrangement, Fig. 8, the integrated outputs of amplifiers 94, 99 are rectified in rectifiers 100, 101, and supplied to a ratio instrument 102 which, by giving a reading proportional to the quotient of the outputs from rectifier 100 and rectifier 101, provides a measure of the permeability of the specimen. Switches 105, 106, controlling the insertion of condensers 103, 104 enable either peak or average readings to be made.

Abstract: 1493065 Discharge tubes SIEMENS AG 26 Feb 1975 [1 March 1974] 7984/75 Heading H1D The collector of a discharge tube-e.g. a travelling-wave tube-is disposed within, insulated from, and spaced from, a cooling jacket 3 provided with channels 11 for the forced passage of a coolant and a blackened inner surface-e.g. of graphite-facing the collector to provide radiation cooling of the latter, which is supported only by an insulator 6 at its input end. Heat flow to the insulator 6 is minimized by a reduction in the wall thickness of the adjacent section of the collector, and, optionally, by the provision of reflecting tantalum screens (not shown). The collector is formed of a low vapour pressure material-e.g. molybdenum, tungsten, or pyrolytic carbon arranged to have its preferred thermal conduction in a radial direction-and the lead 7 permits operation at a desired potential. The chamber formed between the collector and the cooling jacket is either evacuated or filled with an inert gas; a portion of the inner surface of the collector is coated with a zirconium carbon getter mixture; an ion collector in the form of a molybdenum member held at near cathode potential may project into the collector from its base; and the collector may be of multi-stage form, with a sequence of separate electrodes spaced by insulator rings and held at different potentials.
