Title: Gear shifting mechanism
IPC: F16H63/20
Filed: 1928-11-01
Abstract: 319,262. Durant Motors, Inc., (Assignees of Neracher, C. A.). Sept. 19, 1928, [Convention date]. Controlling variable - speed gearing.-Gear-shifting mechanism for motor cars having more than two selector bars is provided with a shift lever normally maintained by springs in a central position, and a locking device to prevent movement of the bars not to be, operated. The shift lever 36 mounted in a ball-and-socket joint 8, 10 engages recesses 48, 50, 52 in shift-bar yokes 34, 38, 44 by gear-shifting movement and is normally maintained in the central position by springs 68, 81. A slide 54 carried on transverse members 56, 58 has a slot 60 which allows of gear-shifting movement of any bar but particles of transverse movement, and the springs 68 tend to move the slide to the left, Fig. 1, and the lever end into the recess 52. This is prevented by the spring 81, stronger than the spring 68, engaging a washer 72 and plunger head 70 coacting with an extension 82 on the lever, by adjusting the effective length of a spindle 74 sliding in a casing 76 so that its extreme movement is that shown in Fig. 1. The locking-device is carried by the slide 54, and comprises lugs 64 formed beneath the slide on each side of the slot 60, and of transverse width greater than that of the recesses 48, 50, 52. When, for example, the lever-end is shifted into the recess 52, the right-hand lug 64, Fig. 1, locks against gear-shifting movement the yokes 34, 38, whilst the opposite lug is now clear of the yoke 44, which can be freely moved for gear-shifting.

Title: Improvements in or relating to arrangements for providing an alternating current signal having a stabilised voltage
IPC: G05F1/42
Filed: 1960-09-16
Abstract: 952,850. Valve and transistor limiting circuits. GENERAL ELECTRIC CO. Ltd., and L. H. ROBERTS. Sept. 13, 1961 [Sept. 16, 1960], No. 32038/60. Headings H3T and H3W. An arrangement for providing an A.C. signal having a stabilized voltage comprises a pentode valve 1 having its anode connected to a line 4 of stabilized potential via the primary 2 of a transformer 3 across which is connected capacitor 5. The anode is also connected via diodes 6, 7 to a second point of lower fixed potential comprising the cathodes of parallel-connected triodes 8, the anodes of which are connected to the line 4 and the grids to the tapping point on a potentiometer comprising resistors 12, 13 connected between line 4 and earth. An A.C. signal is applied to the grid of valve 1 from an input transformer 15, via series resistor 16. The positive excursions of this signal are removed by means of a shunt diode 17, while the negative excursions drive the valve from saturation to cut-off. A resulting A.C. signal is applied to the primary 2 of transformer 3, being limited in one direction by the potential of line 4 and in the other by the cathode potential of the valves 8. The output is derived from tertiary winding 23 of the transformer 3. A further diode 25 is connected between this winding and a point of fixed potential provided by a potentiometer comprising resistors 20, 21, 22 so that if the load across output terminals 24, 27 goes open circuit the diode will conduct and cause the peak amplitude of the signal to be damped by way of capacitor 26, so preventing an excessive voltage appearing at the anode of the valve 1. The valves may be replaced by transistors, while valves 8 and resistors 12, 13 may be replaced by a seriesconnected resistor and Zener diode.

Title: Improvements in or relating to safety guards for mechanical presses
IPC: F16P3/04
Filed: 1948-12-11
Abstract: 654,952. Machinery guards; operating clutches. ATELIERS H. RASKIN. Dec. 11, 1948, No. 32089. Convention date, July 1. [Classes 80(ii) and 80(iv)] In a control mechanism for the safety guard of a mechanical press, a movable member 8 of the guard is connected by links 54, 19 to one arm 20 of a cranked lever pivoted at 23 on the machine frame, tne other arm of which is divided into two branches 21, 22 which are respectively connected to a safety cam 33 and a stop 32 which are arranged m the path of a spring-loaded clutcn actuating arm 30 and are adapted, when the cranked lever is displaced by depression of a rod 25 for moving the guard to its operable position, to be swung in opposite directions to enable the clutch to be spring actuated in the direction which engages the press to operate. The arm 21 is connected by links 27, 28 and 52 to a bush 35 integral with the safety cam 33 and rotatably mounted in a housing 55 secured to the frame of the machine. The stop member 32 is disposed in a recess in the cam 33 and is secured to a shaft 45 disposed within the bush 35 and connected with the lever 22 through links 39, 51, 49. The safety cam 33 and stop 32 are retained in their appropriate positions by springs 37, 41 and a stop 43 against which an extension 42 on member 32 abuts. By virtue of a pin 29 engaging a slot 50 in the member 49, the stop 32 prevents engagement of the clutch until lever 21 has turned through the angle # and the guard member 8 is almost in its closed position. Then, if there is no obstruction to the closure of the member 8, the lever 21 is turned through the angle # and the clutch actuating arm 30 passes between the members 32, 33 and the clutch member 30<SP>1</SP> becomes engaged. A locking cam 31 remains between the members 32, 33 during the working stroke of the slide, and thus prevents any movement of the guard member 8. An inoperative position (shown dotted in Fig. 4), is provided for the arm 3 carrying the movable guard member 8. Removable side guards 17 and a lower front guard 13 are also provided. The guards may be of transparent material in metal frames.

Abstract: 965,468. Mincing. J. LYONS & CO. Ltd. Sept. 7, 1962 [Sept. 7, 1961], No. 32134/61. Heading A4C. [Also in Division B5] Chilled meat is minced by a cutting operation and the still cold minced meat is formed into a thin slice, e.g. as for a hamburger, the temperature of the meat being maintained preferably at or below freezing point throughout. Meat 1, e.g. at 25‹F, from cold store is carried on a conveyer 2, initially chopped by a reciprocating knife 3 and delivered to a bowl 5 rotated on a shaft 6 wherein it is finely divided by a rotary, multi-blade knife 7. The minced meat is delivered by a scoop 10 and guide 11 either directly or by a bucket conveyer 13 into a feed hopper 12 for a screw device 14 which delivers the meat to a rotary mould mechanism 15. The feed screw 14 is arranged to permit slip back of meat along the screw to prevent over feeding. The mechanism 15 comprises a frame mounted on a shaft 16 and carrying radial plungers 17 which are axially movable by a fixed cam 18 so that on rotation of the frame the plungers 17 are reciprocated. Adjacent the feed screws 14 the plungers 17 are drawn radially inwardly to define a mould cavity for the meat. On rotation of the mechanism 15 the plungers 17 are moved firstly slightly outwardly as at 19, to engage the meat with the bottom of a pile of interleaving papers 20 and subsequently a further distance, as at 22, in which position a scraper 23 engages the frame to ensure that the formed slice with paper adhered thereto falls on to an intermittently operated conveyer 24 to form stacks 25. The conveyer 24 may be advanced by means of spaced pins 26 on the mould mechanism 15. The stacks 25 are subsequently cold stored.

Title: Improvements in or relating to electric ship propulsion systems
IPC: H02P9/04
Filed: 1932-11-14
Abstract: 413,668. Systems for transmitting mechanical power; synchronizing. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GARRARD, C. C., c/o General Electric Co., Witton, Birmingham. Nov. 14, 1932, No. 32160. [Class 38 (iv).] Running generators in parallel.-In a ship propulsion system a propulsion motor is supplied from a number of alternating current generators A, B, C operating in parallel, each generator being driven from a separate prime mover, such as a Diesel engine, provided with speed controlling means, and choke coils D, E, F being provided interconnecting the generator winding to facilitate self-synchronization of the alternators and to limit the synchronizing currents. A centre tapped choke coil D1-D3, E1-E3, F1-F3 is provided for each phase of each generator, the centre tapping points of all the coils being connected together to form a neutral point. The extremity of each generator phase winding is connected to one end of its corresponding choke coil and to the opposite end of the choke coil of the corresponding choke coil in the adjacent generator. Thus, phase winding A1 is connected to the top end of coil D1 and the bottom end of coil E1 and so on. The coils thus arranged offer low impedance to load currents but limit synchronizing currents. The coils may be connected between the alternators and the bus-bars and, if the alternators are delta connected, they may be arranged between only two out of the three sets of terminals between the alternators and the bus-bars. If only two alternators are used only one set of choking coils is sufficient. The coils are provided with switches 7, 8, 9 which short circuit them when the corresponding alternators are not operative. Synchronizing of the alternators and starting of the motor is effected with the alternators running overexcited at low speed. Speed control is effected by varying the number of alternators in service and by adjusting the speed of the prime movers. Two separate groups are provided for port and starboard propellers or for inner and outer propellers in a quadruple screw ship. The motors may be asynchronous or synchronous. Separate or common control may be provided and control handles may be arranged to control engine starting, alternator synchronization, motor starting and motor synchronization suitable interlocks being provided to prevent further movement of the handles before synchronization is completed. Interlocks are also provided for preventing connection of an alternator to the bus-bars unless its control handle is in the " off " or engine starting position. Manoeuvring is effected with the alternators delivering low voltage at low speed.

Abstract: 221,402. Tugwood, R. J., (Daimler- Motoren-Ges.). Dec. 22, 1923. Letter-spacing mechanism.- In letter-spacing mechanism for typewriters of the kind in which the movement takes place during the operation of the type-lever through two ratchet wheels co-operating with a common pawl, the abutting faces of the teeth of the two wheels slope in opposite directions and the tip of the pawl is correspondingly sloped so that the pawl slides noiselessly along the ratchet teeth from one tooth to another. One wheel i. Fig. 1, is fixed to a shaft c carrying a pinion d gearing with the spring driven rack e, and the other wheel h is rotatably mounted on the shaft c and is connected to the wheel i by a spring m, the relative rotation of the ratchets h, i being limited by co-operating abutments h<1>, i<1>. The pawl n is pivoted to a spring-pressed lever o carrying an adjustment screw s and operated by an escapement bridge through a rod q, the part being urged towards the ratchet teeth by a spring-pressed pin n<2>, and its stroke being limited by a stop. The teeth of the wheels h, i and the pawl n are shaped as shown in Figs. 3 and 6. During the movement of a type-lever towards the platen, the pawl n moves to the right from the position shown in Fig. 3, slides over the inclined face of the tooth x of the wheel i, and finally leaves the tooth x and engages a tooth y of the wheel h, the wheel i moving forward to the position shown in Fig. 6. During the return movement of the type-lever, the pawl n slides to the left over the inclined face of the tooth y and into engagement with the tooth x<1> of the wheel i, the wheels h, i moving forward into their original relative position, and both having advanced through the distance between the two adjacent teeth x, x<1>.

Abstract: 1429315 Sewing machines A M F INC 5 July 1973 [10 July 1972] 32192/72 Heading D1G The handwheel control 10 of a sewing machine is modified by the addition of cam surfaces 27, 28 which act on followers 35, 36 at certain selected times in the machine cycle to stop the machine in certain needle positions by cutting out the normal drive and introducing an auxiliary drive which operates until the followers 35, 36 reach recesses 27b, 28b in the cams and apply the brake as the followers are raised by the following high parts of the cams. In normal operation of the machine, the followers are held away from the cams, and the machine brake and thread cutter mechanism are in their inoperative positions. The cam followers control valves in a pneumatic circuit (not shown) which operate a thread cutter, auxiliary needle positioning driven piston and cylinder 12, thread tension release and a piston and cylinder pneumatic brake on the machine. The piston of auxiliary drive cylinder 12 has a gripper 13 which may hold a circular section drive band 14 passing around a freewheel drive on the main drive unit 5. When the machine treadle is pressed back the main drive is stopped and the cam followers move in to follow cams 27, 28, and the cylinder drives the machine through the band 14 until the cams act to change the pneumatic circuit and apply the pneumatic brake whilst returning all the pneumatic circuit to its normal position. It is stated that microswitches may be used as sensors and that suitable electrical analogue circuits may be used instead of pneumatic or hydraulic circuits. Further, the machine described stops at the needle-up position. A second cam gap may be provided and suitable delay circuitry so that the second cam gap can be selected instead of the first cam gap to stop the machine in its needle down position.
