Title: Vehicle seat
IPC: B60N2/02
Filed: 1972-04-05
Abstract: 1346398 Resiliently mounted seats ISRINGHAUSEN Gebr 5 April 1972 [5 April 1971] 15665/72 Heading A4U A vehicle seat comprises a seat support 1 connected to a fixed base 4 by a parallelogram linkage at each side of the seat, a damper 9 connected between the base 4 and levers 2 of the linkages, and a spring 8 mounted between a crossbar 17 fixed on the base and an adjusting rod 13 slidable relatively to angular arms 7 which form extensions of the levers 2 beyond their swivel axis 6 in the base, the position of the spring being adjustable to suit the resilience to the weight of the user without affecting the damping and vice versa. The arms 7 are rigidly secured to a pin forming the swivel axis and have guide slots 12 for the ends of a rod 13 which is connected by a plate 15 to the crossbar 17 and which has a female thread engaged by a spindle 14. A gear unit operatively connects the upper end of the spindle to a hand wheel 22 through an arbor 20 which also carries a casting 23 pivoted to the arbor, bolted to the arm 7 and shaped to lie flush with the front edge of the base 4 at optimum weight adjustment for a static load. A rough adjustment of the spring is made against a scale beside the slot 12 and a user, when seated checks by touch whether the casting and base edge are flush and makes further adjustment if necessary. The upper end of the damper is secured to a rod 10 pivotally mounted in a selected pair of series of aperture 11 in the levers 2 or is continuously adjustable in a manner similar to the threaded rod 13 and spindle 14. Rubber buffers 27 abut the front wall of the base 4 to limit downward vibratory movement of the seat.

Title: Synchronising couplings
IPC: F16D23/10
Filed: 1945-06-21
Abstract: 593,973. Toothed and variable - speed gearing; clutches. LEA-FRANCIS CARS, Ltd., (formerly LEA-FRANCIS ENGINEERING (1937), Ltd.), and RIDLEY, J. C. June 21, 1945, No. 15828. [Classes 80(i) and 80(ii)] A coupling device, particularly for use as an isolating clutch at the tail end of a vehicle gear box, utilises a differential gear in which the planet gears are clutched together to give a solid drive and disconnected to free the drive. As shown a bevel gear 11, mounted upon the driving shaft 29 through the intermediary of a splined sliding sleeve 28, engages planet gears 13, 14 carried by a cage 15 secured through a flange 21 to the driven shaft 25, the other bevel gear 12 being freely mounted but having a one-way driving connection 33, 35 with the driven shaft 25. For normal solid drive the planets 13, 14 are clutched together by the engagement of a sliding dog clutch element 37 on the gear 13 with a fixed clutch element 36 on the gear 14. The clutch 37, 36 is disconnected to free the drive when required by a sliding member 45 which moves with sliding sleeve 28, operated through a fork 49 and a rod 50 by the main clutch or change-speed lever of the vehicle so that an operation of changing gear disconnects the coupling. The member 45 engages between coned flanges 44 on the sliding dog clutch element 37 moving it against a spring 38 to free the planet gears which can then rotate to allow the driving shaft 29 to slow up while the movement of driven shaft 25 continues. This rotation of the planet gears introduces centrifugal force by balls 42 which acts to hold the dog clutch 37, 36 disengaged. Thus this clutch cannot be re-engaged until the planet gears stop rotating, which is the condition when the shaft 29 has reached synchronism with shaft 25 after the gear change has been completed. The spring 38 then moves the clutch element 37 to retract the balls 42 and engage element 36 to reestablish a solid drive, the sliding member 45 having been withdrawn by previous main clutch or gear lever operation. The oneway device 33, 35 is provided to prevent the driving shaft over-running the driven shaft should the dog clutch 37, 36 fail to re-engage, due for instance to overacceleration of the engine. The device allows. a reverse drive from the driving shaft 29 to the driven shaft 25 to be obtained without the introduction of any auxiliary. mechanism for this purpose. The bevel gear 12 may be secured to the driven shaft 25 instead of the planet cage which latter is then freely mounted with or without a one-way driving connection onto the driven shaft.

Abstract: 733,079. Penholders. ESTERBROOK PEN CO. June 24, 1952, No. 15895/52. Class 146(3). A penholder having a recessed and internally threaded end portion with a bevelled seat at the inner end thereof is combined with a feedbar having an inclined rear end which effects a camming action against the seat when screwed into the penholder, to wedge the feed-bar and a nib thereon in place. As shown, a penholder P has a threaded socket p having a bevelled seat p<SP>1</SP> engaged by the rear face 11 j of a feed-bar 11 threaded at 11c. The face 11j is slightly inclined to the vertical, such that when the feedbar 11 is screwed into engagement with the seat p<SP>1</SP> the feed-bar 11 is tilted to wedge the nib 12 in place to support the feed-bar 11 firmly. The tilting also ensures correct engagement of the forward end of the nib 12 with the feed-bar 11. The nib 12 is located on the feed-bar 11 by a lip 12a engaging a recess 11g and by a projection 12b formed between parallel slits in the nib shank engaging a recess 11h in the feed-bar 11. A helical space 11d provides a storage space for ink fed therefrom to the ink via a groove 11 f Alternatively, a plurality of annular recesses 11m, Fig. 7 (not shown) or 111m, Fig. 8 (not shown), are provided ; in the latter case the recesses are eccentric to the feed-bar axis. Ink may be introduced into the storage spaces by dipping the feed-bar in ink or by the inkfeeding means described in Specifications 653,391 or 656,656.

Title: Improvements in or relating to boxes made of cardboard or similar materials
IPC: B65D81/18
Filed: 1948-06-14
Abstract: 654,458. Boxes. RIGID CONTAINERS, Ltd., and BURDITT, H. June 14, 1948, No. 15937. [Class 18] A box for livestock has a flanged lid, the disposition of which relative to the box body controls the area of ventilation openings in the box. In one embodiment the edges of the box body have ventilation openings 5 cut in them and positioned to coincide or partly coincide with similar openings 8 in opposite flanges 9, 10 of the lid. The other flanges 14 of the lid are imperforate and thus close all openings on the box sides adjacent to them. The four possible positions of the lid in a square box give four areas of ventilation opening to suit various external temperatures, the box being marked to indicate the lid positions for the particular climatic conditions. The box may have partitions 16, shaped to permit air to pass either from the openings 5 or from openings 18 in the box walls, to the interior of the box. The blank from which the lid is formed may have extensions 23 which form, with the flanges 9, 10, air passages enabling boxes to be stacked side by side without cutting off ventilation. The invention may be applied to the box described in Specification 626,025. The box may be circular or a long rectangular box may have a central partition.

Title: Improvements in or relating to comparison microscopes and other optical comparison instruments
IPC: G02B21/00
Filed: 1938-05-27
Abstract: 498,457. Optical comparator. LEITZ GES., E. May 27, 1938, No. 15950. Convention date, July 10, 1937. [Class 97 (i)] An optical comparison instrument or microscope in which the surface, where the paths of the rays of two objects under comparison are brought together, is arranged between the two objects and the objective of the instrument, is characterized in having a common source of light so arranged that it illuminates the two objects, one directly and the other through one or more reflecting surfaces so that both objects are illuminated from the same side and at the same angle. In the embodiment shown, the instrument has a manipulating handle 2 carrying at its upper end a stereoscopic viewing device 19, adjustable relative to the stand by a focusing wheel 4. The two objects 9 and 10 are placed against plates 7 and 8 provided with bevelled edges to avoid interference with the images, and light from the lamp 11 passes through condenser 12 on to object 9 directly, and through condenser 13 on to object 10 after reflection in the mirror 20. The prism 5 has a partly silvered surface 6 so that rays from the object 9 pass directly through the prism, whilst those from the object 10 are reflected from the silvered surface 6. The images of the two objects are thus seen side by side, the apertures containing the plates 7 and 8 being so positioned that no overlapping of the dividing line on the surface 6 takes place.

IPC: F01D15/02
Filed: 1917-11-01
Abstract: 120,257. Parsons, Sir C. A., Cook, S. S., and Douglas, L. M. Nov. 1, 1917. Toothed gearing.-To dispense with sliding couplings and elaborate thrust block arrangements in geared turbine systems, the turbine rotor b is connected directly to the pinion shaft g by a fixed coupling e having an adjustable pad piece f, and the intermeshing double helical teeth of the pinion c, d are arranged to determine the normal longitudinal portion of the rotor. One of the helices of the double helical pinions may be formed longer than. the other so as to balance the thrust exerted by the turbine and secure uniform distribution of pressure across the pinion teeth and the most favourable distribution of forces so far as deflection due to torque of the pinions is concerned. The teeth of the two helices may be cut at different angles to secure uniform distribution of pressure on the gear teeth. Fig. 10 shows a double reduction gear having the complementary helices in both primary and secondary gears of unequal widths. Instead of unequal widths, the helices may have unequal angles.

Title: Improvements in or relating to light diffusing screens or bodies
IPC: F21V3/00
Filed: 1933-06-06
Abstract: 404,208. Lantern fronts. WALMSLEY, A. R., Over Kellct, Carnforth, Lancashire. June 6, 1933, No. 16125. [Class 75 (ii).] A light-transmitting screen for use in vehicle lamps or in signs, or for other purposes, comprises a layer of reflecting or diffusing crystals 13 interposed between two transparent sheets 12 or moulded plates, each of the crystals having a number of regular facets and being of substantially double pyramid form, i.e. converging towards each end. The sheets and crystals may be of glass. The facets on the two ends may be staggered as shown in Fig. 3, or in line with one another, and the ends may be truncated as shown at 23 or extend to points. The crystals may be arranged regularly, with their pyramid ends between one another, or irregularly. The sheets 12 are spaced apart by a glass or other transparent or slightly resilient central member 15, and by a ring 14 of glass or of rubber or other resilient material. A central bolt 16 with resilient washers 17 holds the parts together. One or both the sheets may be flanged, one sheet fitting within or against the flange on the other. In the form shown in Fig. 5, the sheet 27 is moulded with a central thickened part 47 into which a connecting screw or bolt may be cemented, and a flange 28. The two sheets may be held together by a peripheral band or clip. In the case of a sign, differently coloured crystals may be used to form a letter or other matter, the two colours being confined by a shaped member located between the two sheets, or a stencil may be placed on one of the sheets.

Patent GB-167358-A (GB)
Title: Improvements in or relating to the manufacture of knitted fabrics, and to machines therefor
IPC: D04B25/02
Filed: 1920-06-16
Abstract: 167,358. Knitters & Weavers, Ltd., and Codd, L. B, June 16, 1920. Warp machines.- Relates to an improved machine of the type shown in Specification 14461/11 for producing narrow bands for neckties, belts, girdles, &c. The main part of a band may be made of one and one warp fabric strengthened with cross or filling threads and terminating in fringes formed from warp chains by suspending the two-step shogging movement of the needles. By throwing out the filling yarn at intervals, a narrower fabric suitable for the neckband of the tie is made. Fabric is knitted on a small group of needles A which are fed by groups of radially movable thread guides mounted in the tricks of an upper cylinder H and operated by a cam-groove I, each group of guides containing one more guide than the number of needles fed. The needle cylinder B is shogged by means of a cam K with three working-levels which act on a pin b<2> to place an arm B<2> on a collar B<4> of the needle cylinder B in various positions. The cam K is carried on the end of a lever c mounted on the main shaft E to move up and down slightly under control of a cam d. When fringes or tassels are to be formed, the cam d allows the cam K carried by the lever c to drop to such a level that its highest step K<1> misses the pin b<2>, which is then acted on by the lowest and intermediate levels K<2>, K<3> to give a one-step movement. To obtain plain fabric in place of tasselling. the form of cam shown in Fig. 9 is used. This when depressed still acts on the rod b<2> to give a second slight shog to the cylinder B. The cam d is moved by means of a ratchet-wheel e having wide gaps e<1> at intervals corresponding to the high-level portions of the cam d, which cause tasselling to take place. When the driving-pawl f reaches a gap e<1>, it plays idly therein and the wheel e and cam d remain at rest until re-started by the pins h of a pattern chain g. The filling yarn or yarns a<1> are fed in by a curved horizontal guide a secured at one end to a radial arm a<2> on the top of a vertical spindle a<3> carried in two. half-round blocks b<3> fixed in the cylinder B on the side remote from the needles. The guide a is rocked by a cam i on the lever c, the cams i, k carrying wheels j, j<1> driven by a pinion j<2> on the shaft E. When the cam K is in the elevated position, the cam i acts on a bell-crank lever k<3>, k', k<2>, the end k<2> of which is connected by a chain i lapped round the sleeve part m of the spindle a<3>. The cam i thus shogs the guide a against the, pull of a spring n. When the cam K is depressed to make tassels, the cam i is raised and the shogging movement of the guide a ceases. The filling-yarn a<1> is laid on an outer bevel b of the cylinder and is tensioned by means of a, spring a<9> acting on a curved wire a<7> working in guides a<8> and provided with a tension eye a<5>, the yarn passing in a, zig-zag course between the eyes or hooks a<4>, a<5> and a<6>. Specification 167,052 is referred to.

Filed: 1953-06-16
Abstract: 742,505. Automatic voltage control systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 15, 1954 [June 16, 1953], No. 16563/53. Class 38 (4). The voltage of an A.C. supply is maintained constant by a series transformer which injects a bucking or boosting voltage obtained as the amplified output of a modulator, controlled in accordance with the conductivity of a saturated diode which has its filament connected across the regulated output. The diode VC controls the current through resistor R3 from which a variable negative bias is applied via a low-pass filter to both suppressor grids of a pair of variable-mu pentodes VA, VB. Alternating current from the supply is applied in opposite phase to the two control grids and, as disclosed in Specification 742,143, an output signal is obtained across R7 which, dependent upon the magnitude of the signal from R3, can be varied from a maximum in one phase sense through zero to a maximum in the opposite phase sense with reference to the supply source. This signal is amplified and injected into the supply in a corrective sense via transformer T4. To improve stability the signal at the anode of VA is fed back to its own suppressor grid via cathode follower VD and a filter which removes components .of mains supply frequency.
