Abstract: 126,027. Beardmore & Co., W., and Bremberg, A. Oct. 30, 1916. Ordnance breech mechanism.-Consists in so mounting the breech-operating hand-lever that it is slidable radially in the vertical spindle which it actuates, a handle being provided at each end of the lever and also catch mechanism for locking the parts when either handle is operated. Fig. 1 shows the hand-lever 15 slidably mounted in a guide formed at the upper end of the breechactuating spindle 10 by a plate 12 covering a slot 11. Similar handles 26, 27 carrying spring-controlled plungers 18 are mounted at each end of the lever, the plungers on handle 27 engaging a recess 23 in the spindle 10 when the handle 26 is to be operated and the plunger on handle 26 engaging a recess 22 when the lever has been moved radially from the position shown so as to bring the handle 27 into operation. The plunger on the handle 26 engages a fixed recess 24 when the handlever is in the inoperative position. The plungers are spring mounted in hollow spindles 17 integral with the lever, and are released on gripping the handles as shown to the left of Fig. 1 by the upward movement of sleeves 16 connected with the plungers by radial pine 19.

IPC: E02F3/815
Filed: 1945-06-21
Abstract: 593,967. Scraping-apparatus. BOMFORD & EVERSHED, Ltd., and BOMFORD, D. R. June 21, 1945, No. 15812. [Class 68 (i)] The blade-carrying frame 1 of a bulldozer is pivoted about trunnions on a tractor, the blocks being formed in two sections 3 and 3a, whilst the depth of the cutting edge 5c of the blade 5 is adjusted by means of a hydraulic jack 14 which is pivotally mounted on the frame 1 and which acts on a structure 9 connecting a skid 8 to the frame 1. The skid 8 is disposed on the centre line of the machine. To raise the blade, liquid is pumped from a reservoir 17 by a pump 18 into the jack exerting a force on the piston 13b which causes the skid to exert an up-thrust so causing the frame to turn about the trunnions. The pump may be incorporated with the jack and operated from the driver's position by a link system. The blade is lowered by releasing liquid from the jack by means of a valve 20. The transverse angle of the blade 5 can be adjusted by inserting spacing members between it and the frame. The jack may be replaced by a toggle-lever-like linkage. According to the Provisional Specification, the hydraulic jack is mounted on the structure 9, the piston acting on the frame 1.

Title: Improvements in and relating to control means associated with the automatic synchronising of dynamo-electric machines
IPC: H02J3/42
Filed: 1930-05-23
Abstract: 347,509. Synchronizing dynamoelectric machines. MAHER, G., 213, Washington Street, Braintree, Massachusetts, U.S.A. May 23, 1930, No. 15874. Convention date, May 23, 1929. [Class 38 (iv).] A rotary converter or motor converter is associated with a relay energized in part in accordance with the D.C. armature voltage and in part in accordance with the voltage induced in the field winding during starting from the A.C. side whereby the field winding circuit is established at synchronous speed with a predetermined polarity. An under-voltage relay 20 energizes the low-volt starting-switch 13. The converter then runs up to synchronous speed, the coil 22<11> of a relay being subject to the induced voltage of the armature 10 and the coil 221 being subject mainly to the voltage induced in the field winding 17. These alternating voltages are in opposition until the moment of synchronization and are balanced by suitably setting the rheostat 19. At synchronism the field and armature voltages become unidirectional and act in the same sense, causing the relay to close its contacts 22a. A relay 23 is thus operated to apply a rectified biasing potential to the field winding 17 ensuring correct polarity. So long as the armature voltage is alternating or incorrect in polarity a half wave rectifier 30 prevents the saturation of a choke 25<1>, but with the converter synchronized at correct polarity the windings 27, 28 are saturated by the coil 29 and the relay 26 energizes the running switch 14, a back contact on which de-energizes the switch 13, while another contact closes a maintaining circuit through a contact 24, which may be on a manual or protective switch, by which the A.C. circuit of the converter may be opened.

Class 83 (4) An extrusion press in which the extruded article e.g. a cable sheath or tube leaves the billet container in a radial direction and in which the tools protrude radially into the container. bore, their ends facing each other is characterized in that the tools are supported on means separate from the container and the surrounding parts so as not to be affected by any radial expansion of the container. A radial extrusion press of the double-acting type comprises two hydraulic cylinders 10 having rams 11 with extrusion stems 12. The container assembly comprises a billet container 14 fitted with a liner 15 and a container holder 16. The container 14 rests on the holder by means of radial ribs 17, 18 and is held in alignment by a rib 19 (Fig. 2). Heating means (not shown) are provided in the annular space between the container and its holder. A tubular mandrel 20 and die 21 are backed by adaptor sleeves 23 and distance pieces 24 to form units slidably arranged in cross-bores in the container and provided at the end of each unit is a fixed back-stop 25. The back-stops are secured to crossheads 26 which are connected to each other by pre-stressed tie-rods 28 which pass through hollow extensions 29 on the container holder 16. Whilst the extrusion is in progress the parts of the tool units are forced by the extrusion pressure against the back-stops so that the width of the gap 22 between the tools remains constant and is determined by the back-stops. Specification 699,082 is referred to.
