In transmission gearing for motor vehicles wherein parallel drive branches 1, 2, 4, 5 and 1, 6, 8, 5, Fig. 1, of different gear ratios and including oppositelyacting one-way clutches F and G, are provided between a reversing gear R and the cardan shaft B so that, with forward gear engaged, the clutch G over-runs when the engine drives the vehicle and clutch F over-runs when the vehicle drives the engine, the two drive branches include normally-closed friction or dog clutches E<SP>1</SP>, E<SP>2</SP> and normally-open locking devices S<SP>1</SP>, S<SP>2</SP> for the one-way clutches F, G, by manipulation of which jamming of the gear may be prevented when the vehicle is driven in reverse or tends to roll backwards. Thus, with reverse gear engaged, clutch E' is. opened (or clutch E<SP>2</SP> is opened and looking device S<SP>1</SP>.closed) if the engine is driving the vehicle., and clutch E<SP>2</SP> is opened (or clutch E<SP>1</SP> is opened and locking device S<SP>2</SP> closed) if the vehicle is driving the engine. In the arrangement shown in Fig. 5, clutches 13 and E' are closed for direct drive from engine shaft A through clutch 13 to intermediate shaft 12, thence through clutch E' and one-way clutch F to shaft B. If the vehicle over-runs, drive is from shaft B via gears 11, layshaft 10, gears 14, 15, one-way clutch. G, shaft 12 and clutch 13 to shaft A. For overdrive, locking device S' for clutch G is closed and E' opened, drive from shaft A being through 13, 12, S', 15, 14, 10, 11 to shaft B. Drive in first, second and reverse gears is through the lay-shaft 10, clutches E<SP>1</SP> and 13 being open. In the arrangement of Fig. 6, oneway clutch F is in the layshaft 10 while oneway clutch G is connected directly between shafts A and B. When reverse gear is engaged (as shown), the locking device S' for clutch F is closed. The clutches E', E' and locking devices S<SP>1</SP>, S<SP>2</SP> may be operated automatically in dependence on the direction of rotation of the drive or on the engagement of the reverse gear.

A steplessly variable-speed gear comprises a driving-wheel k which carries radially-projecting spikes l which mesh with the sharp edges of crescent-shaped blades p fast on a capstanshaped hub m on the output shaft, the angle at which the spikes l engage the blades p being variable for change of ratio and direction. The wheel k is fast on a shaft f which is freely mounted in a forked member g and is driven from an input-shaft b through bevels d, e. As shown, the gear is in neutral with the spikes I passing between the blades p. For drive the forked member g which is freely rotatable on the input shaft b is turned in one direction for forward and the other for reverse, output speed increasing progressively to a maximum when the shaft k becomes parallel to m. The spikes l are made of spring steel and have a pointed head of wear-resistant material.

[Also in Division E2] , A pedal-operated refuse bin 1 includes a contents-compressing plate 4 which is mounted on the pedal-operated rod 5 so that when the plate is moved into the bin by spring action, the plate bears rigidly on the contents, and, when the plate is raised to the mouth of the bin, by pressure on the pedal, the connection of the plate to the rod is pivotal and engagement of a flange 12 with abutments 11 pivots the plate to open the cover 13. The end of the rod is received in a sleeve 7, secured to the plate and having a pin 8, which passes through a slot 9 in the rod. The plate is urged by a spring 10 to a position in which the pin is at the top of the slot the rod being within the sleeve and pivotal movement prevented. When the plate is raised to the mouth of the bin, continued pressure on the pedal, with the flange 12 and abutments 11 in engagement, forces the pin to the bottom of the slot and disengages the rod from the sleeve, against the action of the spring 10, so that pivoting can take place. The rim of a detachable lining 2 is secured by a clamping ring 3 pivoted to the bin and, in a modification, the cover 13 is omitted the plate forming the cover of the container.

Abstract: 1,020,479. Checking arrangements for datastorage apparatus. RADIO CORPORATION OF AMERICA. Feb. 10, 1964 [Feb. 25, 1963], No. 5531/64. Heading G4C. In a data storage system, errors are reduced by recording the input information twice; on playback checking the parities of both sets of reproduced signals; and when only one parity is correct selecting only the corresponding set of reproduced signals but when neither parity is correct selecting both sets of reproduced signals. As described, binary data to be recorded on a magnetic tape (or drum) 9 is applied over leads 13 to two sets of recording heads 10-12; 10<SP>1</SP>-12<SP>1</SP>, switches S being in their upper position. For playback, switches S are set to the position shown and the two sets of recorded data read out to flip-flops 20-22, 20<SP>1</SP>-22<SP>1</SP>, respectively, the outputs of these flip-flops being connected to parity checkers 26, 26<SP>1</SP>. If parity checker 26<SP>1</SP> indicates that the seond set of signals is incorrect, AND gates 30-32 are enabled to pass the output signals of the first set to output OR gates 40-42. If parity checker 26 indicates that the first set of signals is incorrect, AND gates 30<SP>1</SP>-32<SP>1</SP> are enabled to pass the output signals from flip-flops 20<SP>1</SP>-22<SP>1</SP> to the output gates 40-42. When the parity of both sets of signals is correct, AND gates 30-32 are enabled by a signal from parity checker 26 over line 27 and OR gate 29 to enable AND gates 30-32 to pass the signals of the first set to the output gates 40-42, the signals of the second set being inhibited by AND gates 30<SP>1</SP>-32<SP>1</SP>. When both parities are incorrect both sets of signals are supplied to the output gates 40-42, so that if the incorrect parities are due to drop-out in different channels in the two sets of signals, the correct output data may nevertheless be provided by the gates 40-42. In a modification (Fig. 3, not shown) both sets of signals are supplied to the output gates 40-42 when both parity checkers 26, 26<SP>1</SP> indicate correct parity so that when correct parity is indicated in one set of signals but two or more elements thereof are in error, the gates 40-42 may nevertheless provide a correct output.
