Title: Improvements in and relating to machines for operating on the edges of soles attached to footwear
IPC: A43D27/00
Filed: 1946-09-17
Abstract: 646,372. Edge-setting. BATA, NARODNI PODNIK. Sept. 17, 1946, No. 27831. Convention date, March 23, 1943. [Class 17(i)] A machine, for operating on a sole edge attached to a shoe in which the work support moves the sole past the tool support, has means which, when released, allows the tool post to be moved in two directions relative to the sole edge. In the edge-setting machine described, a shoe support 1, Fig. 1, is mounted for vertical and rotary movement at 2, 3. A cam system 4 on a shaft 42 driven from a motor 35 imparts the rotary motion through a toothed segment 8 and pinion 9, while a cam shaft 16 gives the vertical sliding motion through a shaft 22 and a chain and sprocket wheel connection to the slide 2. Rollers 5, 17 are kept in contact with the cams by compressed air cylinders. A bracket 50, Figs. 1, 2, is rotatable about a post 52, when a locking pin 48 is withdrawn from a recess 49 at predetermined moments in the cycle of operations on the sole, and has attached to it four levers 51, 51<SP>1</SP> pivoted for vertical movement at 53, 53<SP>1</SP>. Supported at one end is a drive transmitting device 54 and tool support 55, and at the other end, and acting also as a counterpoise, a motor 56. To one lever 51<SP>1</SP> a cylinder 60 is attached so that, when pressure is admitted below the piston 61, it is forced against an adjustable screw 62 in an arm 63 of the bracket 50, so that the tool is forced down on the sole edge against the action of a spring 64 attaching the motor end of the levers to the bracket 50. Two tools 80, 80<SP>1</SP> for operating on left and right shoes are mounted in the post on pins 91, 91<SP>1</SP>, and are moved into working position by a pneumatic cylinder 93 when operated by a valve .A toolheater 94 is provided. The oscillatory rotational movement of the tools is transmitted from the motor by a flexible belt 58 to a pulley 57, which drives a shaft 97 having an offset post 99, which by trunnions 102 on a sleeve 100 and a ball 103 gives a twisting oscillation to a pinion 65 integral with a ball 72 from which, by means of a toothed wheel and racks, the movement is transmitted to the tool. The drive transmiting device can be turned to alter the operative surface of the tool by a toothed piston 68 engaging a pinion 71 to turn the inner gear box 109, and the tool support can be moved to follow the sole edge, such movement being permitted by the ball and lug connection 72, 73. In operation, the tool can be accurately hand guided by a handle 96 close to the heel at the start and also the tool's operative point can be adjusted relative to the stationary work until the locking pin 48 is inserted into the recess 49 by a cam 43 on the shaft 42 to lock the tool while the cams 4, 16 traverse the shoe past the tool. At the end of this traverse the cam 43 again unlocks the tool support to allow the tool to be hand guided to finish the sole edge close to the heel

Title: Data signal transmission system employing phase modulation
IPC: H04L27/36
Filed: 1970-06-10
Abstract: 1318531 Phase-shift data transmission systems NIPPON ELECTRIC CO Ltd 10 June 1970 [10 Feb 1970] 28185/70 Heading H4P In a system for transmitting serial binary data each group of l bits is divided into m sets of bitparallel signals each set separately and uniquely phase modulating a common carrier frequency according to its combination of bits, the modulated signals then being combined produce a signal representing the group of the l bits by its amplitude and phase. The phase of the common frequency for each set of lm bits is shifted by the appropriate increment relative to the phase of the combined signal transmitted for the preceding group of l bits. In the embodiment groups of four serial bits are divided into a pair of dibits, one dibit for the odd and one for the even bits, the four possible combinations of the first dibit of the pair shifting the carrier by 0, 90, 180, 270 degrees and those of the second dibit by 45, 135, 225, 315 degrees. In the modulator (Fig. 5) groups of four bits of the binary serial input 15 are converted into four parallel signals the even bits g 11 , g 12  controlling a modulator 54 and the odd bits g 21 , g 22 , a modulator 55. Within each modulator a phase control circuit 5411, 5511, is on-line while the other 5412, 5512 is off-line, the circuits change over for each group of four bits. The outputs of the modulators are shaped into sine waves by circuit 5421, 5422, 5521, 5522 which thereafter pass through OR gates 543, 553 to form a combined signal 57 via OR gate 56. A phase control circuit when off-line prepares for the next group of four bits by phase shifting the carrier firstly to the phase of the output of OR gate 543, less 22À5 degrees, and then secondly to the phase of the combined signal currently being signalled by receiving all the g 11 , g 12 , g 21 , g 22  signals from logic 53, and then thirdly changes the phase according to the respective g 11 , g 12  or g 21 , g 22  signals of the next group of four bits. A synchronizing signal from a timing circuit 52 is included with the combined signal 57. The demodulators (Fig. 6, not shown), uses the synchronizing signal for automatic gain control purposes and then determines whether the combined signal has an upper or lower amplitude. The combined signal also passes through four phase shifters whose outputs are then compared with the previous four bit combined signal to see whether the four possible phase components 45, 135, 225, 315 degrees are contained in the combined signal. From a combination of the amplitude and phase components the bit the pattern of each four bit signal is determined. A mathematical exposition of the invention is disclosed, which shows that the frequency of the combined signal is concentrated at a number of points in a frequency spectrum.

To measure the time interval between two pulses at inputs A, B (Fig. 5) two pulses E are generated coincident with the clock pulses D immediately following the input pulses, clock pulses M being counted in a counter 17 for the time interval between the two pulses E, a vernier member 18 determining the time intervals t 1 , t 2  between the first input pulse and the first pulse E and the second input pulse and the second pulse E respectively and forming a count in counter 42 representing t 1 -t 2  to modify the count in counter 17. In the embodiment described a distributer 183 (Fig. 4a) in the vernier member 18 receives the pulses E via an inverter 182 and distributes them to N AND gates 181. The input pulses are also distributed via graded delays 185 to the AND gates so that binary coded signals representing the time intervals t 1  and t 2  are obtained at the outputs of the gates. The signals are respectively stored in register 21 (Fig. 5) and via an inverter 39 in register 22 the stages of which are initially preset to "1", register 22 accumulating pulses as register 21 is counted down to zero so that a count of t 1  + (1-t 2 ) is fed to auxiliary counter 42. To compensate for the additional one the start of the count in counter 17 is delayed by delay 34. The counts in the counters 17, 42 are combined in a counter 45. To measure very short time intervals (Fig. 6, not shown) the second input pulse may be delayed by a fixed time and the start of counting in the counter 17 similarly delayed.
