Abstract: 414,898. Clutches ; change-speed gearing. HASSALL, T. G., 9, Albert Square, and STEPHENS, R. G., 18, Park Avenue, Longsight, both in Manchester. Aug. 12, 1933, No. 22536. [Class 80 (ii).] A centrifugally-acting clutch for motor vehicles and the like comprises a liquidcontaining drum 6 secured to the engine shaft 4, and a swash-plate 8 which is centrally fulcrumed within the drum and is caused to rotate therewith by the engagement of slots in the plate with vanes 9 in the drum. The plate coacts with the inclined end of a member 14, which is splined on the end of a shaft 13 and can be withdrawn from engagement with the plate under the control of a collar 15 actuated by a yoke 14a secured to a rock shaft 31. With the engine idling, the plate 8 can oscillate freely within the drum, while as the engine speed is increased the centrifugal pressure of the liquid resists such oscillation and torque is transmitted to the shaft 13. The clutch is shown combined with epicyclic gearing, comprising a sun pinion 19 formed on an extension 11 of the drum 6, planet pinions 20 meshing therewith and with a toothed annulus 23 freely mounted on a final driven shaft 5, the pinions 20 being carried by a member 21 secured to the shaft 13. A sun pinion 27 also secured to the shaft 13 meshes with planet pinions 25 carried by a member 26 secured to the shaft 5, the pinions 25 being in mesh with a sun pinion 24 secured to the annulus 23. A brake drum 29 is carried by the pins 28 supporting the pinions 20. A rock shaft 35 carrying cams 36 controlling a brake band 30 is operated in unison with the shaft 31 through adjustable connections 32, 33, 34 so that when the brake is applied the member 14 is withdrawn from the plate 8. With the engine idling and the vehicle stationary, the drum 6 acts through the gearing to rotate the member 14 idly in the same direction but at a smaller speed. As the engine speed is increased, the speed of the member 14 gradually approaches engine speed, causing shaft 5 to be driven, until finally a solid drive is obtained. By applying the brake, and consequently withdrawing the member 14, a reverse drive is obtained.

Abstract: 1,013,400. Circuits employing bi-stable magnetic elements. RADIO CORPORATION OF AMERICA. June 3, 1964 [June 5, 1963], No. 22989/64. Heading H3B. In a magnetic storage matrix in which sense outputs are induced in digit row conductors by pulsing a selected word column conductor, each row conductor has a sense amplifier connected to its midpoint and has both ends connected through respective characteristic impedances to a reference potential such as ground. A two-core-per bit storage matrix is described in which the storage cores are arranged in four planes 9-12, Fig. 1, a core being located at each intersection of word column conductors 38-41 and digit row conductors 15-18. Each pair of cores 42, 43 forms a digit location 29 into which a digit is written by applying coincident half-current pulses to the associated word column conductor and one of the associated pair of digit row conductors such as 15, 16. Each row conductor is terminated at the ends by characteristic impedances Z 0  connected to ground, and each row conductor pair has its midpoints connected to a differential sense amplifier 20 and to " 1 " and " 0 " digit write drivers D1, D0. Each digit write driver, Fig. 3, comprises a transistor T1 which applies a negative pulse to its respective digit row conductor 15, 16 when a pulse is applied to a terminal 31, 32. The sense amplifier includes transistors T3, T4 connected as emitter followers which are coupled to transistors T5, T6 through diodes 33, 34 and a transmission line 35. Disturbances due to signal reflection in the digit row conductors can be reduced by providing the optional resistors 36, 37 having an impedance as low as Z 0 / 2 . Faster switching times are possible in the arrangement shown in Fig. 4 in which two pairs of digit row conductors 51-58 are connected to a single differential amplifier 20<SP>1</SP> and associated digit write drivers. Optionally one of the branches may be omitted.

[Class 94 (ii)] A machine for making bags &c. comprises mechanism for : (a) feeding a plurality of layers of sheet material; (b) longitudinally sealing them together to form a continuous tube-like structure; (c) feeding and operating on the structure, including transverse sealing and severing devices operating upon selected lengths of the structure, the sealing and severing devices being conjointly operable. Strips 1, 3 of regenerated cellulosic material, preferably having a heat-treatment coating thereon, are led from reels 2, 4, the strip 1 being wider than strip 3 so as to overlap the same at each edge. Two edging strips 5, 7 preferably of coloured material are led from reels 6, 8, and as the edges of the strip 1 are turned upwardly over the edges of strip 3 by the pins 18, so the strips 5, 7 are turned to U-shape to embrace the edges, Fig. 7. The edges of the tube so formed are crimped together by continuously operating wheels 31, 32 in the hollow supporting shafts of which are positioned electric heating cartridges 41, 43. The wheels 32 are supported pivotally about pivots 61 to allow of separation by a hand-operated eccentric 64 to allow of the threading through of the strip materials. The crimping wheels 31, 32 are driven, through an adjustable gear train, by a motor, a clutch being positioned in the driving shaft. After the edges are crimped together, the tubular material is led around a floating roll 70 carrying gears 72 which mesh with racks 73, the teeth being kept in engagement by guide bars 74. Hand operated rolls 79, 82, spring pressed together, the roll 82 being of rubber, feed the tubular material from the accumulation at roll 70 to the intermittently acting device for clamping the same, crimping it transversely and severing off bag lengths. This latter device comprises spring - biassed clamping members 92, 93 which operate to grip the material upon operation of a foot-treadle 156, followed in point of time by the engagement of two crimping blocks 94, 95, heated by electric cartridges 96, 97, which effect the transverse seal 161 of width a, Figs. 7, 8, followed again, in point of time, by the upward movement of the shearing knife 98 which effects severance along Y-Y, Fig. 7. The clamping, transverse crimping and severing mechanisms arc mechanically interconnected to effect the correct sequence of operations on pressing the foot treadle but once.

Title: Improvements in change-speed gearing for automobiles
IPC: F16H61/02
Filed: 1924-09-30
Abstract: 225,819. Enzesfelder Metallwerke Akt.-Ges. Dec. 3, 1923, [Convention date]. Facilitating changing speed.- To facilitate, the engagement of gear and clutch teeth in changespeed gearing, auxiliary friction clutches are combined each with two sets of spring plungers. In the arrangement shown, A is the driving-shaft, B a lay shaft, and C the driven shaft. A pinion q<1> integral with its sleeve k is splined on the shaft C and is adapted to be meshed with a wheel such as m<1> on the lay shaft. The auxiliary friction clutch member n<1> turns loosely and has peripheral teeth x meshing with the wheel m<1>. It is restrained from' moving axially by a ball-ended spring dog p<1> within the shaft C. On moving the sleeve k to the right, the coned friction surfaces come into contact and the gear q<1> and shaft C are driven at the proper speed for engaging the gear teeth without shock. Further movement to the right causes the dog p<1> to slip inwards out of action, releasing the pressure between the cone friction clutch surfaces. The toothed gear q<1> then slips relatively to the gear m<1> sufficiently to allow engagement of their respective teeth. At the end of the movement of the sleeve k, the teeth x of the, member n<1> move clear of the wheel m<1>. In the body of the pinion q<1> are other radial plungers s<1>, which are normally pressed inwards by a spring ring r<1> so that they engage in grooves t<1> in the shaft A. On the movement to the right of the sleeve k, these plungers s<1> ride out of the grooves t<1> and press the spring ring r<1> outwards into a recess z<1> in the member n'. On the return to the left of the sleeve k to disengage the toothed wheels, the ring r<1> engages and drags the member n<1> also to the right with turning until the main dogs p' snap into engagement. On the other end of the splined sleeve k are clutch teeth i adapted to engage like teeth i on the end of the shaft A for direct driving. Here are again the main ball-ended dogs p which hold a friction clutch member w<1> in engagement with a hollow element w long enough for the teeth i and j to come to the same speed. On disengagement of the dogs p, the teeth j, j turn relatively sufficiently to engage without shock. Here again are the other dogs s pressed by spring ring r into taper grooves y in the sleeve k. The ring r on complete engagement of the clutch is pressed into engagement with the element w in a recess d therein holding in position the member w<1> which has been released from the sleeve k.
