Title: Closure for a duct or culvert for retaining a fluid
IPC: F16K17/10
Filed: 1964-09-21
Abstract: 1,129,662. Valves. C. E. BELL. 21 Dec., 1965 [21 Sept., 1964], No. 38345/64. Heading F2V. A closure for stopping-off or sectioning-off of a duct or culvert containing liquids or gases comprises a carrier, forming the periphery of or secured to the periphery of a sliding gate and an inflatable tube, extending along the length of the carrier which, when inflated, forms a seal with a juxtaposed sealing surface of the duct. As shown, the carrier 7 is U-shaped with nylon cleats 10 secured to the carrier to retain the tube 9. When the tube is inflated, the cleats deform. In a modification, the carrier is C- shaped to retain the tube. The tube may be clamped to the carrier at one end with the other end overlapping to allow for a reduction in the length of the tube when it is inflated. The ends may be parallel within or leading from the gate and various forms of sealing plugs are described for the insertion between the overlap.

Abstract: 340,752. Supply measurements. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 16, 1929, No. 38533. Convention date, Dec. 19, 1928. [Class 37.] In apparatus in which condensers, arranged in parallel, are charged and discharged at a frequency proportional to the values to be measured and the charging or discharging currents act in an electrical measuring instrument, means are provided to counteract the charging of one condenser by the discharge of another.

Title: Data processing system
IPC: G06F15/177
Filed: 1975-09-23
Abstract: 1520485 Data processing systems DATA GENERAL CORP 23 Sept 1975 [25 Sept 1974] 39008/75 Heading G4A A plurality of data processors have access to a plurality of memory modules over a shared data bus and a shared address bus, each processor word cycle is divided into a plurality of time phases, and a multiprocessor control unit grants access to the shared buses by different groups of processors only during respective time phases of a processor word cycle. Access to the shared buses by processors within the same and different groups may be granted on a priority basis, with two time phases A, B within each cycle, and four processors A0, Al, B0, B1 the order of priority may be A0, B0, with A1 and B1 sharing the lowest priority. The intergroup priority order is necessary to resolve conflicts of access to the same memory module. Each processor requesting access to a memory module supplies a command code indicating the required memory operation and the control unit passes the command, together with the identity of the requesting-processor, to the memory modules. If a data transfer operation is in progress between a memory module and a processor, a higher priority processor is allowed to access a different memory module, but transfer of data either takes place after the lower priority processor has completed its transfer operation or the data for the first processor is held in a corresponding buffer in the control unit until the higher priority processor has completed its transfer operation. The disclosure is identical to that of part of Specification 1,520,484.

The windings are arranged in two star-connected systems interconnected by an inductor 41 and are connected to line 40 by rectifiers 38. The D.C. motor or other load is connected between line 40 and a centre tapping on inductor 41 through a contactor bridge circuit 43 by which the supply to it can be reversed.

Title: Improvements in or relating to methods of and devices for assembling miscellaneous objects such as bottles, boxes, etc., in predetermined rows
IPC: B65B21/06
Filed: 1960-11-15
Abstract: 938,295. Packaging-machines. E. P. REMY & CIE. Nov. 15, 1960 [March 17, 1960], No. 39218/60. Class 94(1). [Also in Group XXX] In apparatus for handling bottles, packages and other articles where the articles are required to be formed into groups of predetermined configuration for subsequent transfer by a gripping device, e.g. into a packing case, rods or bars are rockable into and out of the gaps or interstices between the articles to form a frame which compels the articles to form regularly aligned rows. As shown the bottles are carried by a conveyer belt 50 and arranged in longitudinal rows by guides 7, 8, 9. The bottles are then divided into spaced batches of the required number to fill a packing case (not shown) by a pair of stop members 10, 14 which are alternately lowered into the path of the bottle by linkage 16 operated by a cam 19. Each stop member consists of a bar 11 having rods 12 depending therefrom. The spaced batches are released by the member 14 in timed relationship with the movement of an endless chain carrying at intervals a set of four mounting members 33, Fig. 4, each of which includes a pair of lugs apertured at 38 for the reception of a longitudinal pin on which a block is rotatable. Bars or rods 39-42 are secured to the four blocks of each set. The bars or rods are rocked about the pins as the chain moves by the co-operation of rollers on the blocks with a cam track having twisted sections at the commencement and end of the upper run. As a result the bars or rods are rocked into the interstices between the bottles to form a frame which holds the bottles in the desired configuration while travelling along, carried by the belt 50. The batches of bottles are continuously removed by an overhead travelling gripper device 49 of known type travelling in step with the bottles as the latter are seized and removed for transfer into a packing case.

A protected area will have a number of units 10, each having a pair of fluid filled hoses connected to separate or a single differential pressure transducer and the alarm 20 is activated when an increased pressure occurs in one only of the hoses. For checking the hoses, the alarm system is disabled and detection circuit 40 is connected in by switch contacts S 1 , S 2  operated by a solenoid drive circuit 30. In response to an input signal I, a solenoid S introduces a pulse corresponding to increased pressure which is reflected back as an increased pressure in the absence of a fault but inverted if a fault, e.g. an air bubble, exists. A time delay switch 24 is provided so that the circuit 40 responds only to the reflected signal to light up one of two lamps F, NF.

In, for example, a multi-contact plug-andsocket unit, adapted for use as a hand-operated switch, the plug member (Figs. 1, 3) comprises a plurality of strip contacts 12, housed in grooves in the curved side of an approximately D-shaped contact carrying portion (see Fig. 3) connected to a cylindrical neck 32 and shoulder portion 31, contact wires 13 passing up through the plug member, to connect with the respective strip contacts 12. The socket member (Figs. 4, 6) comprises a cylindrical contact carrier 21, having a cylindrical bore 22 opening into one of larger diameter 23 (see Fig. 6), resilient strip contacts 25, captive in the sides of the member, being placed across the junction of the bores. In use the plug member is inserted into the slightly larger bore 22 of the socket member until stopped by the top 34 and the neck 32 of the plug member, meeting the socket end plate 37 and segmental web 29 in the threaded socket bush 28, respectively. The plug member is twisted clockwise until stopped by the flat side of the top part 34 of the plug member, meeting the face 40 of a right-angled projection in a bore in upper socket member 36, thereby forcing the socket contacts back, as in Fig. 6, making simultaneous electrical contact between all of the plug-and-soket contacts. Contact pressure is increased by flat spring 41 in the upper socket member 36. Specification 748,480 is referred to.
