Title: Improvements in or relating to circuit arrangements for automatically checking digital data
IPC: H04M3/523
Filed: 1961-02-14
Abstract: 946,132. Telegraphy. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 14, 1961 [Feb. 17, 1960], No. 5456/61. Heading H4P. In a circuit for detecting an interruption in a sequence of incoming ordinal numbers, for example the serial numbers of telegrams, a received number is compared with a number one greater than the previously received number. If the comparator indicates inequality there must have occurred an interruption in the sequence of ordinal numbers. In order to record the beginning and ending of the interruption the numbers compared are passed to further registers, whence they can be noted by an operator. The incoming two digit serial numbers are in 2 out of 5 code. Suppose the present incoming number is N. In register RG2, due to reception of the prior number N-1, there is stored a number which is also N. The incoming number is stored in register RG1 and also passed to a translation circuit TS, given in more detail in Fig. 2 (not shown), which produces at its output a number N +1. The signals stored in RG1 and RG2 are compared in unit VS and if equal, as in the present case, the numbers are erased. The number N+1 from TS is then transferred to register RG2 and stored therein prior to comparison with the next serial number-which should be N+1- to be received by register RG1. However, should the latter number not be N+ 1 but some other number M, the comparator will indicate inequality with the result that this number M is transferred to register RG3, and the number N+1 in RG2 is transferred to register RG4. An alarm is operated. The circuit TS generates the number M+1 for comparison with the next serial number. The registers RG3 and RG4 may control digit dials which thus indicate the number last received, i.e. beginning a new sequence, and the number which should have been received, i.e. beginning the interruption. The number stored in RG4 remains there until erased by the operator. Should a second interruption occur before erasure the number stored in RG2 is erased and the number in RG1 marking the beginning of a new sequence of numbers is transferred from RG1 to RG3.

Abstract: 410,496. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., GOULDBOURN, J., KEALL, F. B., and KESTELL, T. A., Belgrave Road, Leicester. Oct. 11, 1932, No. 5818 /34. Divided on 410,463. [Class 112.] The invention relates to boot-sole sewing-machines of the general kind described in Specification 23478/10, [Class 112], and consists in high and low speed driving mechanism and lubricating mechanism for the machine described in Specification 410,463. The shuttle mechanism is the same as described in Specification 392,947 and the rotary take up as described in Specification 390,842. The operation of the high and low speed driving mechanism is as follows. Assuming the machine to be stopped and the driving belt connected to the pulley which is fast on the countershaft or motor to be running, the small pulley 165 is coupled to the driving member 177 on the countershaft and large pulley 169 on the main shaft is driven thereby. The small pulley 175 on the main shaft, driven by the engagement of the block 209 on the inner face of the large pulley 169 with one face of the recess 211 in the periphery of the disclike member 205 on which the large pulley is mounted and to which the small pulley is secured, will rotate idly the large pulley 171. The lever 299 will, in stopping the machine be raised by a cam on the main shaft 15 and will be held in its raised and right-hand position by the spring plunger 311. It will, through the rocking shaft at the rear of the machine, be holding the presser foot raised and the lower thread lock unlocked, the upper thread lock being also unlocked. The connections whereby this shaft raises the presser and opens the lower thread lock are described in Specification 410,463. When the treadle 17 is depressed, the cam 279 is swung upwardly and actuates the lever 289 to swing the lever 299 away from the cam to release the spring plunger 311 and allow the presser to drop on to the work. Upon further partial depression of the treadle, the upper end of the cam 279 engages the lower end of the screw 277 in the arm 275 the clutch lever 263 to disengage the hooked end thereof from the block 259 on the lower end of the lever 251 and allow the clutch to close and drive the machine at slow speed. Still further depression of the treadle raises the arm 270 still further till the latch 273 engages the small plate 295 on the cam lever 289 to move the driving member 177 out of engagement with the small pulley and into engagement with the large pulley, to drive the machine at high speed. Reverse movement of the treadle effects reverse operations, the machine being brought to rest at the same point in the machine cycle. Lubrication. For lubrication, there is provided an oil pump in the hollow arm 77 projecting from the sump. The pump consists of a bracket 137, Fig. 15, below the shaft 73 and a plunger 141 so that as the shaft 73 is rocked, the plunger is reciprocated to effect a force-feed lubrication through various apertures to various parts.

Abstract: 608,704. Lifting-jacks. ELECTRO-HYDRAULICS (MESSIER), Ltd. (formerly MESSIER AIRCRAFT EQUIPMENT, Ltd.), and CALDWELL, H. B. Feb. 27, 1946, No. 6183. [Class 69 (ii)] The piston rod of a fluid-pressure actuated jack is locked in any particular position, e.g. either or both of its extreme positions, by two cooperating members, one of which is carried by the cylinder, or a member connected thereto, and the other by the piston rod, the arrangement being such that when the piston is actuated one -member passes through and rotates the other member which is biassed to return to its normal position so that when the first member has passed therethrough its return movement is prevented.. The co-operating members are a splined collar 4, Fig. 1, fast on the piston rod 3 and a splined washer 6 rotatably mounted in the cylinder 1, these members being so designed that the splines on the collar can pass through the grooves 5, Fig. 2, of the washer and effect the rotation of the latter. A projection 7 on the washer takes into a slot 8 in a plunger 9 which is movable in a fluid pressure chamber 11 against a spring 10. This spring returns the washer to its normal obstructing position as soon as the collar has passed therethrough. In order to permit the return movement of the piston, fluid under pressure is admitted to the chamber 11 through a port 14 to rotate the washer. Fluid under pressure is admitted to the cylinder through ports 12, 13, the admission of fluid through the port 13 being controlled by a valve (not shown) actuated by the plunger 9. In a modification (not shown), this valve and the port 14 are dispensed with, the plunger 9 has parts of two different cliameters which are acted on by fluid admitted through the port 13.
