Title: Data Transmission Systems
Inventor: AINSCOW FRANK
IPC: G06F11/10
Filed: 1968-09-10
Abstract: 1,169,687. Error detection and correction; error detection and correction. INTERNATIONAL BUSINESS MACHINES CORP. 10 Sept., 1968, No. 42906/68. Headings G4A and G4C. In a data transmission system, a word includes M groups of data and check digits each digit belonging to a unique configuration of groups and each group satisfying the same logical operation, successive shifts of a shifter producing different groups in sequence at predetermined digit locations of the shifter which are connected to logic means to perform the logical operation, the success or failure of the logical operation for each group being recorded in a result register. As described, a 7-bit word having data bits at positions 3, 5, 6, 7 and even parity check bits for respective groups at positions 1, 2, 4 is inserted into the shifter which is shifted in the pattern (calling the shifter stages A, B . . . G) A to D, B to A, C to E, D to B, E to F, F to C, G to G, three times. Before each shift a parity check is performed on stages D, E, F, G and the results (in the result register) are finally decoded to identify the erroneous bit (if any) which is then corrected during read-out of the shifter. The arrangement can be used for producing the check bits from the data bits to construct the word in the first place. Use in computers and storage is mentioned. Ternary and hexadecimal digits are also mentioned. Instead of correction, error detection may cause retransmission or tagging the word bad.

Abstract: 1,029,278. Laminates; sheet forming. CARL FREUDENBERG. Nov. 15, 1962 [Nov. 20, 1961], No. 43276/62. Headings B5A and B5N. A method of making a moulded article, e.g. a brassiere, comprises uniting at least one non- woven fibre batt to a heat-mouldable plastic foil by needling, with consequential perforations in the foil, and then moulding the composite material under heat to the desired shape. Fibre batts may be applied to one or both faces of the foil which may have additional perforations made in it either before or after laminating. The layers may be partially united by heat and pressure before needling and several fibre batts may be united by needling before application to the foil. The fibre batts may be of straight or crimped fibres of one or more kinds, and examples of a wide range of natural and synthetic fibres are given including animal, vegetable, mineral, many types of synthetic, cellulosic and protein fibres. Fleeces may be formed by carding or flocculation using a suction drum, several thin fleeces being superimposed with the fibres of one at an angle to those of another to form a batt. The foil may be a vinyl or acrylic polymer or copolymer, a polyester, a cellulose ester, a polyurethane, a polyolefin or halogenated polyolefin, examples being given, a preferred material being polypropylene. The foil may be oriented. The batt on one side of the foil may be calendered smooth and the material shaped by vacuum moulding or deep drawing, e.g. using a silicone-rubber blanket. The composite material may be pre-shrunk by steam treatment.

Patent GB-1487697-A (GB)
Title: Electronic timepiece
IPC: G04G5/00
Filed: 1975-10-24
Abstract: 1487697 Electronic timepieces DAINI SEIKOSHA KK 24 Oct 1974 [14 Nov 1974] 43814/75 Heading G3T An electronic timepiece is provided with a circuit for correcting the seconds indication, the circuit, including an up-down counter 23, Fig. 3, which increases its count by one each time an advance-setting switch S1 or a retard-setting switch S2 is momentarily closed, and reduces its count by one each time a 1-second pulse P1 is produced by a frequency divider circuit 9. In normal operation of the timepiece a selecting gate circuit 12 passes only the divider output pulses P1 to a driver circuit (not shown) e.g. for a step motor driving the seconds hand. The seconds indication is advanced by passing additionally a pulse P2, derived by a delay circuit 11 from the divider output P1, through the gate circuit 12 to the driver circuit each time S I is momentarily closed as illustrated, Fig. 2b (not shown). The seconds indication is retarded by the gate circuit 12 blocking a pulse P1 from the divider each time S2 is momentarily closed. When advancing the seconds, the momentary closure of setting switch S1 sets a flip-flop T11 and a flip-flop S11, thus opening an AND gate 63 to pass a delayed pulse P2 via an OR gate 61 to the driver circuit along with pulse P1 so that the seconds indication is set forward by 1 second. At the instant S1 is closed the counter 23 input CL receives a logic "1" and counts one unit. When the next P1 pulse is produced an error prevention circuit 26 reduces the count to zero. A detector circuit 21 detects the content of counter 23 and causes an advance-reset circuit 16 to reset T11 and S11 and consequently the AND gate 63 is closed to block further pulses P2. When retarding the seconds, the momentary closure of S2 sets flip-flops T12, S12 and the resulting "0" output of inverter 12 causes an AND gate A62 to block a pulse P1 and counter 23 counts one pulse. When the next P1 pulse is produced  error prevention circuit 26 causes AND gate 2a to close and reduces the count to zero. The count detector circuit 21 and a circuit 20 reset T12 and S12, one pulse P1 having been blocked. A similar procedure is repeated to change the seconds indication by more than 1 second. Gate circuits G1, G2 serve to reduce the effects due to chattering of switches S1, S2.

The output conduit (12) is connected to the inlet duct 18 to a pump 19 which discharges the fluid to a dialysate regenerator system comprising a urea removal column 46, an activated carbon column 47 which absorbs creatinine and uric acid, an ultraviolet steriliser 48 which prevents baterial growth in the dialysate and a filter 51. The regenerated dialysate is then passed back into the abdomen via ducts 23 and (11). The pump 19 consists of two chambers A and B separated by a piston 28 with one way valves 31, and a diaphragm 34 connected to the piston by a ring 36 and to the end 27 of the chamber B. The shaft of the pump is sealed by a diaphragm 40 connected to the end 27 and shaft by rings 41 and 42 respectively.

Abstract: 947,536. Bowden mechanisms. FORD MOTOR CO. Dec. 12, 1961 [Dec. 19, 1960], No. 44387/61. Heading F2K. The sheath 13 of a Bowden cable 12, in a motor vehicle heating and ventilating system, is clamped by means which resist sheath axial movement relative to a support under normal load but which, for axial adjustment, allows the sheath to be moved to take up a new position when greater than normal load is applied. In Fig. 1, the sheath 12 is clamped between an arcuate portion 16 of a support 15, integral with or bolted to a fixed member, and an arcuate portion 17 of a strip steel spring clamp 14 an arcuate portion 21 of which embraces the support portion 16. Clamp tabs 23 locate the clamp on the support. Indentations 22 on the clamp and support engage the grooves formed by spirally wound wire of the sheath. In Figs. 4-6 and 7-9 (not shown) the sheath is clamped between a support and a clamp which is loaded by a Belleville spring reacting on the support through a rivet which serves to locate the clamp. The support and/or the clamp may have sheath-engaging indentations. A tongue on the clamp engages a support slot to limit relative movement therebetween. In Figs. 10, 11, the sheath is encircled and engaged by an indented portion 66 of a clamp member 63. A support 64 embraces the portion 66 and has teeth 69 engaged by tabs 68 of the clamp member 63 which is loaded by a strip steel spring 62 riveted to the support. When load greater than normal is applied the tabs 68 move free of the teeth 69 to permit axial movement of the clamp 63 and the sheath relative to the support. In Figs. 13-15 (not shown), which embodiment is similar to that of Figs. 10, 11, an indented clamp member encircling and engaging the sheath has teeth engaged by tabs of a member loaded by a Belleville spring reacting to the support through a rivet which guides axial movement of the clamp member.
