Abstract: 185,535. Fry, H. D. June 15, 1921. Accelerometers with recording-apparatus, - Comprises two moving parts, such as the field and armature of an electromotor, driven by means independent of the motion of the aeroplane or like carrying the instrument, but arranged so that their speeds are changed by acceleration of the aeroplane so as to give an indication or make a record thereof, from which the speed and distance covered may be calculated. Two sun-wheels e, g, Fig. 5, are rigidly attached respectively to the field a and armature b of an electromotor, which are adapted to rotate about a common axis in opposite directions normally with the same - speed, the field a being loosely mounted on the shaft i of the armature b, which is pivoted to the field at a point j, the whole being pivoted in bearings 23; the mounting is such that the friction is evenly distributed between the sun-wheels, and adjustable balance-weights are provided. Each sun-wheel carries a number of radial cylinders k filled with liquid and having balls l movable therein, so that the centre of gravity of each wheel is always below the axis of rotation. Contacting with the sun-wheels are a number of planetary wheels n supported in a cage o to which is secured an eccentrically-mounted crown-wheel in the form of a reflector p whereby light from a lamp is thrown on to a sensitive film t, which is passed from one drum to another by clock-work. The reflector bears two wide frosted lines which cause at intervals a slight blur in the record by means of which the number of revolutions may be counted, and change in direction may be detected. The instrument is pivoted at 23 in a gimbal-ring mounted in the frame of an air-tight sphere, so that the sun-wheels rotate in a vertical plane through the longitudinal axis of the aeroplane. In a modification shown in Fig. 11, the crownwheel o is mounted centrally, and, together with the casing 36 to which it is secured, moves through a small angle against the action of spiral springs 34 attached thereto and to the framework. A lamp is mounted on the underside of the crownwheel, and a record-chart having a central zeroline is used.

Title: Variable reciprocating movement transmission
IPC: B30B1/32
Filed: 1958-05-23
Abstract: 873,502. Hydraulic presses. LIGHT, G. S. May 23, 1958 [July 15, 1957], No. 16673/58. Class 69 (2). [Also in Group XXII] A transmission for imparting irregular reciprocatory movement to a tool or work carrier 12 comprises means 1, 9 to reciprocate the carrier and means 6 automatically operative at any predetermined period during the movement imparted to the carrier by the means 1, 9 to impart a predetermined pattern of substantially coaxial irregular reciprocatory movement to the means 1, 9. The carrier 12, which may carry a stamping tool 14, is slidably supported in a guideway 13 and pivotally connected to the rod 10 of the piston-and-cylinder device 1, 9. The upper end of the cylinder has an extension 4 in which is a hole engaged by an eccentric 6 on a shaft 7 supported in bearings 8. The shaft is provided with a lever 19 adjustably supporting an arm 20 having at its remote end a follower 22 spring-urged into contact with a rotatable cam 17 fixed to a shaft 18. In operation, fluid pressure is supplied alternately to the ends of the cylinder to reciprocate the piston and carrier 12 from a valve which is adjustable to vary the length and timing of the reciprocatory movement. At the same time, rotation of the cam 17 rocks the eccentric 6 to impart a reciprocatory movement to the cylinder, the spacing of the high portions of the cam causing the latter movement to be additive to, or subtractive from, that of the piston at the ends of, or during, either the forward or reverse strokes of the piston.

Title: Improvements relating to gun-controlling mechanisms
IPC: F41G5/22
Filed: 1944-09-01
Abstract: 587,951. Ordnance mountings. MORRIS MOTORS, Ltd., and LANDSTAD, H. F. Sept. 1, 1944, Nos. 16704 and 25122. [Class 92 (i)] [Also in Group XXXIII] Means for compensating the effects of pitching and rolling on the setting of guns or other apparatus used on ships or military tanks, comprises a member b pivoted, in the case of guns, on the gun mounting on an axis at right angles to the vertical plane containing the gun barrel and carrying a gyrostat c, a member d pivoted to b on an axis parallel to or in the vertical plane containing the barrel and carrying a gyrostat c<1>, and three arms e, f, g pivoted to member d, the relative movements between the member -b and the gun mounting and between the three arms serving respectively to provide compensating movements to the gun during pitching and rolling. As shown, the upper arm e and middle arm f move in a vertical plane about pivots e', f<1>, while the lower arm g is pivoted about a horizontal axis g on a member h which pivots on a vertical axis. Arm g is connected by a pin s to an arcuate member i, the pin passing through a horizontal slot t<2> in an extension t on arm f. Member i is guided by rollers l, m on the member b and is moved in an arcuate path by a pinion on a shaft r rotated by the elevating mechanism of the gun. The pinion also meshes with a rack on another curved member p connected to the upper arm e. Thus all three arms are elevated when the gun is elevated. When the vessel carrying the mechanism rolls, and assuming the gun to be elevated, the member i tilts about the axis of shaft r as shown in Fig. 4, causing the arm g to move to the left. and, by means of pin s, pulling down the arm f slightly. The arm e remains stationary. Such relative movements of the arms are used to actuate a controller to apply compensating training and elevating movements to the gun. Thus, downward movement of arm f with respect to arm e actuates the controller by a rack and pinion device 4, 5, as shown in Fig. 2, to apply compensating elevating movements, while training compensating movements are effected by the operation of the controller through a rack 7 on arm h engaging a pinion 8 on member d. Rack- and-pinion mechanism 2, 3, Fig. 2; between member b and fixed bracket a actuates the controller to compensate for pitching. Further rack-and-pinion mechanism 18, 19, Fig. 4, on members d, b respectively is actuated during rolling and serves to operate a controller for driving an electric motor, adapted to apply appropriate rotary motions to the sight.

Title: Vehicle braking mechanism
IPC: F16D65/54
Filed: 1958-05-27
Abstract: 878,127. Disc brakes. TRIGGS, W. W. (Airheart Products Inc.). May 27, 1958, No. 16828/58. Class 103 (1). A brake-actuating mechanism comprises a fixed member 10, a piston 17 connected to a braking element 11 and slidable in a cylinder 13, and a connection between the piston and the fixed member confining the movement of the piston between predetermined limits corresponding to the brake clearance, the connection including a holding device having a friction grip ring 41 exerting a holding force on the piston which is greater for movement of the piston in the brake applying direction than in the opposite direction. A disc 20 is held against the piston 17 by ring 21 and has a hub 24 supporting a stud 27 extending into an auxiliary piston 29 slidably mounted in a bushing 14 closing one end of cylinder 13. A tubular member 37 screwed to bushing 14 has a bevel edged, radial flange 38 coacting with the ring 41 mounted on the auxiliary piston 29, the ring 41 having a second bevelled edge 42 engaging a ring member 44, a Bellville washer 45 biasing the ring member 44 and grip ring 41 to the left in Fig. 1. In operation, fluid-pressure moves piston 17 and disc 20 towards the brake disc 12 until the shoulder 35 on the stud 27 engages a collar 33 secured to the inside of auxiliary piston 29, this movement being the normal brake clearance, further movement of the piston due to wear causes the auxiliary piston 29 to slide through the grip ring 41; on release of fluid pressure a spring 36 withdraws piston 17 until disc hub 24 abuts piston 29 to re-establish the brake clearance, the protruding end of piston 29 giving an indication of the degree of wear. Should the pad 11 be engaged with the disc 12 in the release position, for example after installation of a new pad, then on braking, pressure in the cylinder moves the auxiliary piston 29 outwards until collar 33 engages shoulder 35 on stud 27 to establish the brake clearance. In Fig. 2 not shown, the bushing 14 is modified to be attached from the outside of the cylinder and the stud 27 is formed integral with the disc 20; in Fig. 3, not shown, the disc 20 is housed in the bushing 14 and the grip ring is between the main piston and the auxiliary piston, the main piston having a bevelled edge engaging the grip ring which can be preloaded by the adjustment of the bushing 14; Fig. 4, not shown, is similar to Fig. 3, but with the bevelled edge formed on the auxiliary piston.

Title: Automatic fabric take-up device in knitting and like machines
IPC: D04B15/88
Filed: 1957-05-28
Abstract: 859,442. Fabric take-up. SCHELLER, J., and SCHELLER, H. May 28, 1957 [May 28, 1956], No. 16951/57. Classes 74 (1) and 74 (2). [Also in Group XXXV] The torque supplied by an A.C. motor (Group XXXV) to a take up roller 11 of, say, a knitting or netting machine is transmitted by an aluminium bell 28 carried on a rotatable shaft 9 and movable axially into and out of the air gap between rotor 23 and stator 21 to vary the electromagnetic drag imposed on the bell and so the torque transmitted. The bell may be moved by the narrowing spindle nut 4 of a straight-bar knitting machine, acting through linkwork, including a lever 6 and a connecting rod 8, so that the specific tension remains constant irrespective of the width of the fabric ; or it may be moved by the patterning means to vary the torque in accordance with loop structure; or the lever 6 may be displaced by a cam disc. The lever 6 has pin- and-slot connection with the nut 4 and is pivoted at 15. A lever 14, also pivoted at 15, is linked at its end to the rod 8 and is fast with a bevel wheel 7a ; and a shaft 17 rotatably mounted on the lever 6 bears at one end a bevel pinion 7 meshing with the wheel 7a and, at the other end, a hand wheel 10. Thus, the wheel and pinion 7a, 7 normally act merely to connect levers 6 and 14 ; but, through them, the bell may be given an initial setting, by means of the hand wheel, independently of the nut 4. The rod 8 may be connected to the free end of the bell-shaft 9 ; or that shaft 9 may be provided with grooves 30 acting as a rack and meshing with a pinion 31 rotated by a lever 32 or by belts or gearing, or hydraulically.

Title: Improvements in hoisting appliances
IPC: B66D5/32
Filed: 1920-06-23
Abstract: 146,272. Keller & Knappich Ges. Aug. 17, 1918, [Convention date]. Geared pulicy - hoists; driving-gear; brakes. - A geared pulley-hoist oontrolled by movements of the hand chain wheel 13 has the wheel mounted on a screwed sleeve 10, Fig. 3, which engages a screwed disk 23 fitted with a peripheral one-way ball-clutch 26 arranged between the disk and housing 14. A clockwise rotation of the chain-wheel 13 screws the sleeve into the disk 23, locks the disk to the housing by means of the ball-clutch and presses a flange 24 of the sleeve against a brake-disk 25 and so forces the brake-ring 22 against the housing, thus coupling the housing to the driving pinion 2 of the pulley-hoist and so raising the load. A slight contra-clockwise rotation of the sleeve 10 releases the brake-disk 25 and frees the pinion 2 so that the load can be lowered under the influence of centrifugal weights 19 acting on the brake ring 22. The unloaded hook can be lowered by a continued contra-clockwise rotation of the chain-wheel, the screwed-disk 23 being first released by means of a pin on the sleeve 10 and the governor weights being held inoperative by means of a cut-away part 17 of the sleeve.

Title: Improvements in or relating to the production of lampshades
Inventor: BARBER GEOFFREY
IPC: F21V1/26
Filed: 1961-05-10
Abstract: 932,973. Lampshades. BARBER & TYTHERIDGE Ltd. May 7, 1962 [May 10, 1961; Nov. 2, 1961], Nos. 17015/61 and 39344/61. Class 75 (2). In a method of producing lampshades, at least one disc of a film of non-self-supporting plastic reinforced around a central aperture by the application of a ring of plastic is applied to a rigid frame with the reinforced part centred in respect to a supporting ring and stretched, the stretching being facilitated by the application of heat to the non-reinforced part. In one form, two similar discs 10, 11 with reinforcing rings 13 are placed in register and welded at the margins around a shape retaining ring 12. A rigid supporting frame 16 is then forced through the central aperture 14 in one of the discs and the discs stretched over the frame, hot air or electric heating element being used to heat the non- reinforced parts to 180-200‹ F. during stretching. In a modification, a sleeve portion of the same or different plastic having end rings is sprung over the rings of the two discs and the whole stretched over a supporting cage. Alternatively, the two discs may be applied to opposite ends of the supporting cage and stretched until one retaining ring can be snapped over the other. A single disc stretched over a frame may also be used.

Title: Circuit arrangement to compare two information items
IPC: G06F7/02
Filed: 1965-04-23
Abstract: 1,087,257. Comparators. INTERNATIONAL STANDARD ELECTRIC CORPORATION. April 23, 1965 [April 28, 1964 (3)], No. 17193/65. Heading G4M. In a magnetic core comparator, each of a set of cores represents a respective signification of one comparand. In Fig. one of a number of magnetic cores K1. . . Kn is set to represent one comparand, the other comparand being set up on relay contacts KU 1... KUL each of which connects an output winding L1 . . . LL threading a selection of cores either to earth or to a further winding SK which threads all the cores in the opposite sense. The other ends of the output windings pass to a diode OR gate. A positive-negative pulse is then used to reset the set core. If the two comparands are equal each output winding L1. . . LL either has a pulse induced in it cancelled by a pulse induced in the further winding SK or has no pulse induced in it and is earthed, but if the comparands are unequal, the OR gate will receive at least one pulse the polarity of which will depend on the direction of the inequality. The core arrangement may be a translator for use in automatic telephone exchanges and the comparator above used for checking its operation. Alternatively, the comparator may be used as a translator, the cores being switched in turn until equality is obtained with the relay contact settings. Fig. 3 (not shown) shows a modification (operating similarly) in which transistors replace the relay contacts. When conducting, they earth their respective output windings and backbias off diodes leading to the further winding. In Fig. 4 (not shown) the further winding is omitted but a pair of output windings is provided for each bit of one comparand, each core being threaded by one winding of each pair. Switches earth one winding of each pair and leave the other floating. The output windings feed an OR gate. In Fig. 5 (not shown), output windings leading to an OR gate thread selected cores of a first group and are connected in series with respective output windings threading cores of a nominally similar second group. Corresponding cores in the two groups are set and reset in such a way that output pulses from the two groups, produced on reset, cancel giving no output from the OR gate, unless a fault exists. The core groups may be translators in a telephone exchange system in which ease the translator outputs are used for call control only if they agree as above. The cores may be square-loop cores as above or may merely act as transformers.
