Title: Improvements in or relating to telephone systems
IPC: H04Q3/58
Filed: 1934-03-16
Abstract: 435,155. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., and HARTLEY, G. C., 63, Aldwych, London. March 16, 1934, No. 26392. Divided out of 435,398. [Class 40 (iv)] Alternating current signal impulses are applied in phase to the two conversational wires in parallel. The signals may be used for repeated metering during conversation without causing clicks in the receivers, or they may be used by a toll-operator after setting up a connection back to a calling coin-box party to bring about current reversal in the line circuit for coin collect or refund purposes. For repeated metering in a district office system, the timing apparatus is located at the main exchange M and periodically closes tc to apply ringing current to a transformer MT having its windings so arranged that A.C. in the same phase is applied to the legs of the junction in parallel. At the district office D, relay TM, shunted by a rectifier, is connected to the junction of bridge relays DS, IS and is operated by the A.C. to effect metering such as by releasing DB. Relay DS shunted by rectifier MRA is operated to effect normal metering on reply of the called party, and rectifier MRA is disconnected during A.C. signalling to preserve line balance.

Patent GB-286241-A (GB)
Title: Controlling devices for motor vehicles
IPC: A63G25/00
Filed: 1927-10-07
Abstract: 286,241. Aktiebolaget Spontan. March 1, 1927, [Convention date]. Controlling different functions by same lever.- A brake-control member and a reversing gear control member are connected in such a manner that movement of the brake-control member beyond that necessary for applying the brake permits engagement of the reversing control member with the reversing-gear, the reversing control member being inoperative before the brake is applied. A single member may control the brake and reversing gear, and may also control the vehicle engine. The invention may be applied to a vehicle having an automatic change speed and reversing gear of the type operating by centrifugal force. In the construction shown, a pedal 72 pivoted at 74 controls the accelerator lever 99 between positions I and II, a spring-applied brake (not shown) between positions II and III, and the reversing gear between positions III and IV, the brake being still applied in the last case. The spring which applies the brake raises the pedal from II to III, and a stirrup 75 is provided by which the pedal may be raised from III to IV to put the changespeed gear in the reversing position. The pedal carries a pawl 76 controlled by a spring 77 so that in the position IV, shown in full lines, the pawl engages one tooth of a star wheel 43. When the pedal is depressed to position III the star wheel is rotated through one tooth and this is arranged to shift the change-speed gear from its forward position to the reverse, or vice versa. The pedal now cornes in contact with a stop 83 on the brake lever 84 also pivoted at 74. Depression of the pedal from III to II causes (1) the pawl 76 to pass over the star wheel leaving the latter in its new position, and (2) the brake lever 84 to be depressed and release the brake through a link 85, lever 87 and other linkage (not shown). The lever 84 is raised to apply the brake by means of a compression spring 98 acting between one point 96 of a link 95 and one corner 97 of a toggle linkage which has a fixed pivot 93 and another corner 91 pivoted to an arm 90 of the lever 84. The linkage is so arranged that the leverage of the spring is greatest in position III, i.e. when the brake is fully applied, and least in position II. Finally, when the pedal is depressed from II to I it acts on the accelerator lever 99, the brake being unaffected. When the pawl 76 is disengaged from the star wheel it is rotated by its spring 77 until an arm 89 engages a notch 88 in the top end of the brake lever 84 and locks the brake lever to the pedal. Thus if the brake spring 98 is fractured the brake lever 84 can be raised to apply the brake by means of the stirrup 75 .and the pedal 72. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an automatic gear forming the subject-matter of Specification 281,983, [Class 80 (ii), Gearing, Variable-speed &c.]. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in shuttles for looms for weaving
IPC: D03J5/24
Filed: 1920-03-17
Abstract: 142,746. Sowerbutts, W. T., and Forrest, J. March 17, 1920. Shuttles.-In a hand-threaded shuttle, a saw slit B is cut vertically, or approximately so, in the centre of the head A<1> and opening into a longitudinal weft hole b, a second slit C is cut inclined to the slit B and leading to an inclined weft hole c below it and to the slit eye D in the side of the shuttle, and a third slit E is cut parallel to the longitudinal axis of the shuttle and inclined to the side along which it extends from the slit C, so that the slit C is not cut through the top of the shuttle for the whole of its length. A hole b<1>, preferably inclined to the vertical, is bored at the junction of the slits B, C to the bottom of the weft hole b, and an inclined pin G, around which the yarn passes, is inserted at the junction of the weft holes b, c. To thread the shuttle, the yarn is passed along the slits B, C to the top of the shuttle above the slit E, and further pull on the yarn parallel to the axis of the shuttle causes it to pass through the slit E to the outside of the shuttle where the loop can be caught and the yarn pulled down into the slit eye D. An inclined pin F across the slit B prevents the yarn from ballooning out of the weft hole b, and an horizontal wood or metal pin G<1> prevents the yarn when slack from ballooning out of the hole b<1>. Tension pins may be inserted into the weft hole b, and a spiral wire or other eye may be employed instead of the slit eye D.

Title: Improvements in zinc smelting
IPC: C22B4/04
Filed: 1950-11-06
Abstract: 681,514. Distilling zinc. NEW JERSEY ZINC CO. Nov. 6, 1950 [Jan. 12, 1950], No. 27072/50. Class 82(i) Oxidic zinciferous material is smeltered in an electric arc furnace with carbonaceous reducing material so that the zinc vapour produced is substantially free from dust-forming impurities and the slag is substantially zinc-free. The zinciferous and carbonaceous materials are charged into the furnace in a loose, dry condition and in such relative amounts as to effect reduction of at least a major portion of the zinc component of the charge and of at least such a portion of any iron component present in the zinciferous material to preclude the presence in the molten slag of more than 6 per cent by weight of iron oxide (calculated as Fe). The slag produced from the above smelting must contain not more than 85 per cent by weight of CaO and SiO 2 , in a ratio of between 0.9:1 and 1.2:1 and not exceeding, with respect to the total amount of the other constituents of the slag, the ratio represented by the line AB. The slag is maintained in a molten condition at a temperature of at least 125‹C by electric arc heating and the charge is smelted on the surface of the slag at a temperature not in excess of 1450‹C. The charge component may be fed separately, in simple admixture or as agglomerates. The zinc vapour may be condensed in a condenser as described in Specifications 601,246, 601,247, 620,644, 648,529 and 657,205.

Title: Improvements relating to devices for separating cut films from a stack
IPC: G03B17/34
Filed: 1959-08-07
Abstract: 866,635. Photographic cameras. OPTISCHE INDUSTRIE DE OUDE DELFT N.V. Aug. 7, 1959 [Aug. 19, 1958], No. 27145/59. Class 98(1) [Also in Group XVI] Cut photographic films are separated sequentially from a stack from a position 15, Fig. 1, into a position 16 by means of a member 24, Fig. 3, adapted to be rotated about an axis perpendicular to, and opposite a corner of, the foremost film of the stack, the member 24 having a small disc or ring of rubber or other material having a high coefficient of friction which engages the corner of the foremost film. A needle on the axis of the rotatable separator member 24 pierces the corner of the foremost film so that the latter is separated from the stack to the position 16 by a rotation about the said axis. The apparatus is shown as applied to a viewer, but it could be arranged in a developing machine or a photographic camera. The front plate 1 is supported by three legs 2, and the stack of films is arranged in front of a pressure plate 3 which is backwardly inclined in a sloping V-shaped channel and urged forward by a rod 20 and spring 28. Replenishment of the stack can be effected by rocking a rod 30, pivoted at 31, the lower end of the rod engaging a fixed abutment 29 on the rod 20. A transverse shaft 7, rotatable by a handle 8, carries skew gears 9, 11 in mesh with skew gears 10, 11, respectively fixed on parallel shafts 43, 23, and also carries two cams 32, 33. The shaft 23 is perpendicular to the films, and carries the separator 24 against which the films are urged by the plate 3. The plate 3 has a small projection arranged opposite the separator 24, and a strip 19 wherein the rod 20 is fitted. The shaft 43 carries a member 41 similar to the separator member 24, and is opposite an idler counter roller 40 on a rod 36 which is urged forwardly by a spring 38 so that a rod 34, in a block 35 secured to the rod 36, engages the cam 32. The stack of films is urged periodically away from the separator 24 by the end 50 of a bar 48, pivoted at 49, which is oscillated by the cam 33 acting on a spring- urged rod which has a collar 45 in engagement with the bar. In operation, when the handle 8 is rotated, the foremost film is separated by the member 24 and rotated to the position 16 to abut stops 13, 14 and lie between a front transparent plate 4 and a rear opal glass plate 18 (not shown) behind which is a light source. On further rotation of the handle 8, the cam 33 urges the bar 48 to press the film stack away from the separator 24; then the cam 32 allows the roller 40 to press the film at 16 against the member 41 which rotates the film about its axis into a position 17, Fig. 1, above a delivery magazine 5, where it is released when the roller 40 is retracted. A hook 42 on the member 41 assists the delivery of the film into the magazine 5.

Title: Magnetic recording apparatus
Inventor: JNR HARRY CARL HINZ
IPC: G11B20/18
Filed: 1971-04-19
Abstract: 1,274,630. Data storage; error detection. INTERNATIONAL BUSINESS MACHINES CORP. 19 April, 1971 [27 May, 1970], No. 27186/71. Heading G4C. In a magnetic recording system (e.g. multi track magnetic tape) digital data read out is inspected for quality, error detection means detect code errors, and validation means produce a probable validity signal in response to quality and detected errors. By this means an error correction code can be applied to that data which is probably in error to the exclusion of that data which is apparently correct. Recording Fig. 1.-Data signals are received and stored as six 4 bit groups and in step 11 an 8 bit error detection and correction code is generated. In step 12 the six 4 bit groups and the 8 other bits are converted into eight groups of 5 bits each, for example a run length limit type code (the run lengths of # limited to two) for NRZ1. The eight groups are then recorded on magnetic tape in step 13, preferably each group on one of eight parallel tracks. Readback.-The data is readout in the usual manner in step 14 and the readback quality of each track is monitored e.g. for excessive phase shift, excessive amplitude deviations, excessive velocity deviations excessive base line shift or incorrect received wavelengths. In monitoring, the quality of overlapping windows is measured (Fig. 2, not shown). If the quality is marginal, a pointer is applied to step 16. In step 15, the data is reconverted to its original form and in step 16 the reconverted data is combined with the marginal pointers to provide valid data. Error correction (Figs. 6 to 9, not shown).- The error detection circuits comprise two syndrome computers (mainly exclusive OR circuits) which produce syndromes indicating the position of errors in the data (Fig. 7). The syndrome and quality signals are then combined, the error position is exactly specified, and then is corrected in a known manner. Other features.-The readback apparatus includes a deskewing circuit, detection of special characters, self clocking codes and a counter.
