Title: Improvements in or relating to ordnance breech mechanism
IPC: F41A17/18
Filed: 1918-12-19
Abstract: 141,778. Dawson, Sir A. T., and Buckham, Sir G. T. Dec. 19, 1918. Ordnance breech mechanism. - Relates to pivoted inertia-actuated hang-fire safety devices, and consists in means involving the use of a single spring only for holding the device in disengaged position after firing until the breech is opened, and for causing the safety catch to reengage on closing the breech. Figs. 5 and 8 show the device in plan in its disengaged and engaged positions respectively. The safety device comprises a catch member C integral with a weighted inertia member D and pivoted at d to the underside of the breech-actuating lever A. The nose of the catch engages a projection b on the breechscrew arm B or other convenient part, and its outward movement is limited by a pin d' moving in a recess A<1> in the lever A. The catch C is held in engagement by a spring plunger E mounted in a socket in the member D and bearing upon an incline b<1> of the member B, as shown in Fig. 8. When the gun is fired, the inertia member D swings forward relatively to the part B and releases the catch C, and the plunger E enters a recess B<1>, as shown in Fig. 5, and holds the catch disengaged. When the breech is being closed, the plunger E, the outward movement of which is limited by a stud e engaging the wall of the recess A', re-engages with the incline b<1> and, during the final locking movement of the actuating-lever A, rocks the catch C into operative position. The lever A may also carry a spring retaining-latch engaging with a recess B<x> in the member B.

Title: Improvements in and relating to apparatus for washing and cleaning crockery, cooking utensils and the like
IPC: A47L15/39
Filed: 1949-08-19
Abstract: 658,325. Washing crockery and the like. STAINES KITCHEN EQUIPMENT CO., Ltd., and BENNETTS, A. E. Aug. 19, 1949, No. 21660. [Class 138(i)] In an apparatus for washing and cleaning crockery, cooking utensils and the like, having a pair of oppositely rotatable brushes, and means for supporting an article such as a plate for engagement between the brushes for rotation thereby, the supporting means comprises rollers at least one of which is disposed with its axis at an angle to the axis or axes of one or more of the remaining rollers, so as to impart a lateral twist to the plate. As shown in Fig. 1, a gear box c, containing an electric motor driven worm and pinions driving stub shafts o, and having a flange in the form of a face plate d, is mounted in an aperture in the side b of a pressed steel sink, and is held in position by screws at e. An apertured boss f and spring clips h on the face plate d receive the vertical portion of a bracket g, the horizontal leg of which extends across the base a of the sink and is connected to cradles l carrying rotatable rollers j and k. The vertical leg and a greater part of the horizontal leg of the bracket g are coincident with the longitudinal mean centre of the brushes i, which are screwed on to the stub shafts o, and thereby the traverse centres of both rollers are offset from the said mean centre. The outer portion g<SP>1</SP>, g<SP>11</SP> of the horizontal leg of the bracket g is bent obliquely to the mean centre. The roller k is situated adjacent the outer ends of the brushes which are unsupported and present unobstructed ends over which cups and similar hollow articles may be pushed for cleaning their interiors. The rollers j and k have parallel central portions j<SP>1</SP> and k<SP>1</SP> and conical portions j<SP>11</SP> and k<SP>11</SP>. A plate positioned between the brushes i will rest with its edge on the portion j' of roller j and on that portion k<SP>11</SP> of roller k which is nearest to the longitudinal mean centre of the brushes. The brushes revolving inwardly towards the sink bottom a will tend to force the plate edge down the conical portion k<SP>11</SP> on to the central portion k<SP>1</SP> and this tendency is resisted by the outer end of the nearest brush so that the opposite sides of the plate will be held hard between the brushes and it will assume a lateral twist. When it is desired to use the sink without the apparatus, the brushes and bracket are removed and a cover plate p, Fig. 4, is positioned over the plate d and stub shafts o and is held in position by spring catches q which snap over the stub shafts.

Abstract: 1,193,961. Rolling. DAVY & UNITED ENG. CO. Ltd. 16 May, 1967 [16 May, 1966], No. 21712/66. Heading B3M. A rolling mill comprises housings 12 which are maintained in a prestressed condition by struts 17, but are intially prestressed by roll gap adjusters 21. To prestress the housings, the adjusters 21, which may comprise screws, wedges or hydraulic cylinders, are actuated to stretch the housings beyond a value corresponding to the maximum rolling load. Spacers 32 are then positioned, together with wedges 31, to take up any clearance between the struts and housings. When the adjusters 21 are slackened off, the prestressing forces are taken by the struts. Packers 16 allow rolls of different diameter to be used in the housings. An automatic gauge control apparatus may be used in the mill. Signals corresponding to the positions of the adjusters 21 and to the loads in load cells 22, together with a desired thickness signal from a potentiometer 38, are fed to a computing circuit 40. An output signal representing the deviation in thickness of the rolled product from its desired value is fed to the adjusters 21 in order to reduce the deviation. When the adjusters 21 are wedges, their bearing surfaces are provided with roller bearings, with a P.T.F.E. coating, or with oil under pressure in order to minimize friction.

Title: Data communication system
IPC: H04N1/333
Filed: 1973-05-08
Abstract: 1393647 Facsimile transceivers XEROX CORP 8 May 1973 [16 May 1972] 21867/73 Heading H4F Transceiver units in a facsimile transmission system each include a control circuit which indicates receipt of a ready signal from a remote receiver when the transceiver is acting in a transmit mode, and a speed of transmission signal from a remote transmitter when the transceiver is acting in a receive mode so as to synchronize the speed of the receiver carriage with one or other of two possible transmission speeds. Each transceiver control circuit includes a filter, a voltage window detector responsive to a frequency band represented by a voltage range, and two detection circuits. One detection circuit has a delay time sufficient to insure receipt of a valid ready signal over noise when the transceiver is in the transmit mode, and a smaller delay time sufficient to assure valid reception of a speed selection signal when it is in the receive mode. A transmit or a receive mode signal is applied to this detection circuit to determine its mode of operation. The other detection circuit is gated when the voltage window detector detects a signal indicating the other speed of transmission, the two speeds being indicated by different frequency signals which are converted to voltages for comparison with the voltage window of the voltage window detector. The receiver ready signal is specifically a 1500 Hz tone having a duration equal to or exceeding any expected noise duration, and the two transmission speed indicating signals comprise a 1500 Hz tone and a 1100 Hz tone.
