Title: Improvements in or relating to hydraulic-control apparatus
IPC: F15B7/10
Filed: 1947-05-06
Abstract: 636,217. Hydraulic transmission of power. SPERRY PRODUCTS, Inc. May 6, 1947, No. 12206. Convention date, May 25, 1946. [Class 69 (ii)] In a hydraulic control apparatus wherein each side of a double-acting transmitter 11 is coupled by liquid-transferring connections 27, 28 to the respective sides of a double-acting receiver 21 whereby separate hydraulic systems are formed having valving mechanism for connecting a liquid reservoir 30 to one of the systems and disconnecting the reservoir from the other hydraulic system when the transmitter 11 is actuated, the valving mechanism comprises a stationary valve casing 40 and a movable valve body 45, liquid connections 41, 42 between the hydraulic systems and opposite sides of the valve body, whereby the valve body 45 will be moved in response to the pressure in the higher-pressure hydraulicsystems, the casing 40 having a plurality of passages 50, 51 communicating with the reservoir 30, the valve body 45 having a plurality of ports 46, 48 adapted to co-operate with the passages in the casing, the distance between the ports 46, 48 being different from the distance between the passages 50, 51 by an amount such that only one port can register with its respective passage at any time, and the difference in distances between ports and passages being sufficient to prevent the second port from registering with its respective passage until the first port has passed a predetermined distance out of register with its respective passage whereby no liquid can pass between the hydraulic systems. The Specification as open to inspection under Sect. 91, describes two modifications. In one, the valve body is normally maintained in a central position by a spring acting on each end, so that both sides of the pistons are connected to the reservoir by means of a through bore in the valve body. When the transmitter is operated, the valve body is moved to cut off the reservoir connection for such a time as there is an increase in pressure on one side of the pistons. Any number of such apparatus may be connected to one reservoir. In the other modification, the valve and casing is replaced by two diaphragms embodying perforations, which in conjunction with a bored and ported cross-web situated between the diaphragms, normally connects the reservoir to both sides of the transmitter and reservoir. An increase in liquid pressure applied to either diaphragm causes its collapse against the adjacent face of the cross-web and thereby closes the reservoir connection to the pressure side of the pistons until the pressure increase has ceased, whereupon the resiliency of the diaphragm returns it to its original position. This subject-matter does not appear in the Specification as accepted.

Title: An improved window locking device
IPC: E05B65/08
Filed: 1935-04-23
Abstract: 440,236. Window fastenings. STUART, G., 28, Wellington Street, St. Kilda, Victoria, Australia. April 23, 1935, No. 12225. [Class 44] A window fastening comprises a spring pressed bolt A in a casting B secured to the edge of one window frame, the bolt engaging recesses G in the other frame and being adapted to be withdrawn by movement of the tapered end O of a metal strip L through the slotted end of the bolt, or by movement of an eccentric 4, Fig. 3, pivoted in the slotted end and engaging the casting at a point above the bolt. The eccentric has a downwardly inclined arm 3 connected to an actuating rod 1. The lower end of the rod L or rod 1 may have a guard Q to prevent access thereto from outside the window when the latter is open. The bolt is pressed outwards by a spring D engaging a pin E on the bolt and by pressing the bolt against the base of the recess G prevents window rattle. The recesses G are reinforced by a metal strip V having inclined edges U at the lower edges of the holes to facilitate retraction of the bolt when the window is moved in the closing direction. Alternatively a rack strip W, Fig. 13, may be used without cutting recesses G. Figs. 17 and 19 show a modification in which the pin which closes the outer end of the slot in the bolt engages a recess a in the strip L when the bolt is shot, and before the strip can be moved longitudinally it must be moved laterally against a spring b. In this case the rod moves in a casing c slotted to take a projection e<1> on the strip by pressing which the lateral movement is effected. The spring b may be housed in a bore in the end of the bolt.

Inventor: SHERRIFF ROBERT RANKIN
IPC: F41A9/87
Filed: 1916-08-31
Abstract: 106,390. Sherriff, R. R. Aug. 31, 1916. Lever load-handling machines; screw - and - nut load - handling machines. - In carriers for transporting heavy bodies such as shells, of the kind which are mounted upon wheels and provided with suspended lifting-tongs held closed by the weight of the body transported, means are provided for raising or lowering the lifting - tongs relatively to the carrier. The tongs A, Fig. 3, are supported by chains C attached to a bell-crank lever J, Fig. 1, which is rocked by rotating the shaft P. Movement of the tongs is limited by drag chains R connected to the side plates S of the under-framework, the front and rear plates of which are curved so as to fit the shell. In a modification, the tongs are supported by the short arm of a lever, and the long arm is locked in its lowered position by a pin. In both constructions, the shell, when raised, may be brought into contact with resilient means, such as a spring pressed plate, for steadying purposes instead of into contact with the curved plates before mentioned.

Title: Novel products of the amino-piperidine-2, 6-dione series
IPC: A61K31/00
Filed: 1955-04-29
Abstract: The invention comprises compounds of the general formula <FORM:0768821/IV(b)/1> wherein R represents hydrogen, an aliphatic radical (saturated or unsaturated) which contains 1 to 6 carbon atoms, a phenyl radical or a benzyl radical and X represents the radical of the imide of a dicarboxylic acid attached to the piperidine ring by the imido nitrogen atom.  The imides may be of aliphatic, cycloaliphatic, aromatic or heterocyclic dicarboxylic acids.  Such products can be prepared by reacting an aliphatic dicarboxylic acid which contains 5 carbon atoms in a straight chain and the a -methylene group of which contains the substituent X, or a functional derivative of such an acid, with urea or a substitution product thereof or with a primary amine or an acid amide in such manner that water is split off and the ring closed.  In examples: (1) N-phthalyl glutamic acid and aqueous ethyl amine are reacted to form 1-ethyl-3-phthalimido-2,6-dioxopiperidine; (2) N-succinyl-glutamic acid ethyl ester and propylamine react in the presence of sodium methylate to give 1-propyl-3 - succinimido - 2,6 - dioxopiperidine; (3) N - phthalyl-glutamic acid anhydride and urea are heated together to give 3-phthalimido-2,6-dioxopiperidine; (4) ammonia is introduced into molten N-phthalyl-glutamic acid anhydride to give 3 - phthalimido - 2,6 - dioxopiperidine.  Similarly prepared is (7) 1 - benzyl - 3 - phthalimido - 2,6 - dioxopiperidine.  The reaction can also be effected in benzene solution; (14) 1-allyl - 3 - phthalimido - 2,6 - dioxopiperidine is prepared similarly. 3-Phthalimido-2,6-dioxopiperidine is also prepared in Examples (6) and (10) to (13) by reacting N-phthalyl glutamic acid or its anhydride variously with ammonia, urea and thiourea.

Title: A process of producing enamelled articles having a multicoloured appearance and product thereof
IPC: C23D5/06
Filed: 1932-04-30
Abstract: 395,482. Enamelling. PORCELAIN ENAMEL & MANUFACTURING CO. OF BALTIMORE, 5601, Eastern Avenue, Baltimore, U.S.A. April 30, 1932, No. 12513. Convention date, May 6, 1931. [Class 56.] A process for producing vitreous enamelled articles having a multicoloured appearance consists in forming a rough surface on an article applying colours to the surface in such a manner that the article appears to be of different colour when viewed from different directions, and then firing the article to produce a smooth surface. In carrying out the process, the article A is first cleaned and a preparatory or ground coating B may be applied. A moist enamel coating C may then be applied, and coarse particles E of enamel frit are dusted on to the moist coating to form a rough surface. Alternatively, the rough coating may consist of crushed glass, or of minerals having low fusing-points, and it may be incorporated with a fluid binder. The rough surface may also be formed by any other suitable method, such as by using a rough, dull enamel for the ground coat. A light dusting of enamels of different colours is next applied to the rough surface from different directions, by means of spraying-devices D, D<1>, for example, so that each colour is mainly applied to different facets F, G of the particles E. The article now appears to be differently coloured according to the direction from which it is viewed. Finally the coated article is fired, and the enamel fuses and forms a smooth surface which has a multicoloured appearance produced by the diffusion of the colours employed. Compositions of suitable enamels are given in the Specification, and Specification 5536/93, [Class 16, Books], is referred to.

Filed: 1945-05-18
Abstract: 592,133. Mercury switches. MESTITZ, E. May 18, 1945, No. 12616. [Class 38 (v)] A mercury, or other conducting - liquid, switch comprises two communicating chambers 1, 2, preferably made of glass, holding the mercury 23 and an expansion fluid, such as hydrogen, a heating element 9 and a supply electrode 13 in container 1, a load electrode 15 in container 2, a tube 8, having a narrow crosssection at least at one point, and an elevated neck 7 so that a conductive path is formed between electrodes 13, 15, when the mercury is pressed by the heated hydrogen over neck 7 into container 2, and is interrupted when the hydrogen cools down and the mercury recedes back over the neck 7. The heater circuit is completed by depressing a push-button 22 and is maintained automatically when the mercury rises in the inverted-V tube 3 to contact electrode 17, thereby short-circuiting an operating electrode 16. Upon continued heating of the hydrogen, the heating circuit is broken at 17 thereby permitting the gas to cool and the mercury to return to its normal position shown. If the press-button is still depressed when contact is broken between electrode 17 and the mercury, the hydrogen forces the mercury down still further until the load and heating circuits 13, 15 and 13, 16 are broken by a second neck 4. A reservoir 19 is provided to enable the volume of mercury in the containers, and hence the setting of the switch, to be variable.

Title: Improvements in or relating to railway vehicles having central buffer couplings
IPC: B61G9/10
Filed: 1934-04-28
Abstract: 421,440. Combined buffmg and drawgear for railway vehicles. KNORRBREMSE AKT.-GES., 9, Neue Bahnhofstrasse, and KAISER, W., 17a, Augustastrasse, both in Lichtenberg, Berlin. April 28, 1934, No. 12894. [Class 103 (v)] In a combined buffing and draw-gear for railway vehicles of the kind in which the coupler-heads a at each end of the vehicle are associated with resilient gears c, d, e which are connected by a tubular force-transmitting member i for transferring the shocks from one end of the vehicle to the other, free movement of the member i relative to the underframe is prevented by the interposition between these parts of friction elements acting in diametricallyopposed relation and adapted to exert a resistance of constant value. In one arrangement, Fig. 1, opposed friction blocks k are pressed laterally upon the member i by means of springs or compressed air. In a modification, Fig. 2, the blocks k are arranged at each end of a longitudinally disposed spring and have bevelled outer surfaces coacting with corresponding surfaces on abutments m on the underframe. In this arrangement, movement of the member i in either direction releases the pressure of one set of blocks, the effective resistance being derived from the other set. Assembly or removal of the gear may be facilitated by making the underframe stops g removable.
