Abstract: 521,783. Hydraulic rams. BLAKE, Ltd., J., and WARREN, F. Feb. 16, 939, No. 5037. [Class 102 (ii)] [Also in Group XXIX] A waste valve for hydraulic rams and similar apparatus comprises a main closure member adapted to move into and away from its seat, said closure being formed with an annular aperture or apertures or ring or rings of apertures adapted to be closed by a subsidiary resilient disc secured centrally to the main closure. In the form shown in the figure the main closure a is formed integrally with a pivoted guide cage n slidably mounted on a seating ring b and is adjustably secured to a spindle a<SP>1</SP> adapted in the open position of the valve to engage a buffer. This buffer comprises a cylinder k slidably mounted on a fixed pin i with an interposed rubber cushion h. The subsidiary disc d is mounted on a barrel-shaped extension of the hub of the main closure. A resilient seating for the main closure may be formed by a ring clamped between the ring b and the casing or an outer flanged ring. In a modification the spindle a<SP>1</SP> is extended and slides in a fixed socket to guide the main closure, the cage n being then omitted. In this form a resilient ring is mounted between a collar on the spindle and the end of the guide socket to form a buffer.

Abstract: 1499204 Digital data processing PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Feb 1975 [9 Feb 1974] 5072/75 Heading G4A A digital data processing system comprises a relatively slow and large capacity main store MS, a relatively fast and small capacity buffer store BS, an incoming address WBA from an address register AR being compared in a comparison device V with word block addresses ab0-ab3 stored in an address register AS of the buffer store; if a comparison is found one of the word blocks wb0-wb3 stored in the buffer store BS is selected by lines l0-l3 for use by a processor P viaan I/O register BSR of the buffer store; if a comparison is not. found a signal on a line l4 causes the word block WB with the desired address to be accessed in the main store MS by a selection unit SE and used by the processor P via an I/O register MSR of the main store; at the same time that word block and its address are respectively stored in the buffer store BS and in the address store AS. The invention resides in the fact that the address WBA has a part WDA which is decoded at WDAD and used to select, via gates e0-e3, one or more of four portions w0-w3 of the selected word block in the buffer store BS. The selected word block portion(s) are then overwritten with a modification sent from the processor P via a data register PDR and the modified word block stored in the main store MS via register BSR, a line L, and the register MSR. A plurality of processors P and/or a plurality of main stores MS and buffer stores BS may be provided (Fig. 1, not shown). The address store AS and the comparison device V may be replaced by a single associative address store. In another embodiment (Fig. 3, not shown), portions of a word. block can be independently read and written into, the modified portion of a word block being read directly from the processor P into the main store MS, while the unmodified portions of that word block are read, simultaneously with the above reading operation, from the buffer store BS into the main store MS.

Abstract: 411,232. Label - punching machines. HAMILTON & SONS, Ltd., J., and HAMILTON, E., Star Iron Works, Pollard Street, Ancoats, Manchester. Feb. 20, 1933, No. 5130. [Class 31 (i).] In a label-punching machine, means are provided for automatically disconnecting the drive from a reciprocating worktable without stopping the crosshead c and to bring it to rest in the forward position after each reciprocation until the driving connection is again made manually, the crosshead being continually reciprocated by connecting rods d and cranks on the shaft e. The table is linked to a lever m, pivoted on the frame at l and linked to one end of another lever n, which is pivoted on the frame and carries a bowl o<1> maintained in contact with a cam o by an overhung weight p, and a spring q acting on the lever m. The spring and weight also serve to restore the table to the forward position, or alternatively the cam may be double-acting. The cam is free on the shaft e but is adapted to be connected to the shaft in timed relationship with the crosshead by a sliding pin and hole clutch which is allowed to engage on depressing the lever t. The lever is immediately released and, after one reciprocation, the clutch is automatically disengaged, and the table is arrested in the forward position by a brake which is applied when a follower engages a notch on the periphery of a member forming part of the cam o. Other suitable forms of clutch may be used, and the levers m may be connected to the table by pin and slot means instead of links. The cam and levers may be replaced by a crank and connecting rod for reciprocating the table, the connecting rod having an adjustable slot engaging a pin in the table so as to allow the table a variable period of dwell beneath the crosshead.

Abstract: 536,506. Closures for containers. NIEBURGS, H. E. March 27, 1940, No. 5482. [Class 125 (iii)] A liquid container 5 has a neck 6 of circular section in which is secured a closing plug 8 of resilient material and of frusto - conical form, its upper and lower diameters being greater than that of the bottle neck. The plug has one or more passages 9 and is covered by one or more thicknesses of fabric 10, such as Willesden canvas, which permits only slight percolation by liquid. To insert the stopper it is first placed in a cylindrical sleeve 11 with its smaller end entering first and its larger end ready to enter the container neck 6.

Abstract: 517,306. Directive wireless systems. DAVIES, G. L. Feb. 20, 1939, No. 5527. Drawings to Specification. [Class 40 (v)] In a landing-beam system in which a glidepath of constant field-intensity is produced by direct and ground-reflected radiation from an elevated transmitting aerial array, the shape and elevation of the glide-path is adjusted by providing a prepared ground surface having a suitable coefficient of reflection. Thus the path may be made steeper by providing a surface having a lower coefficient of reflection than the normal ground surface, e.g., a surface composed of some granular material such as sand ; a flatter path is produced by a surface having a higher coefficient of reflection, e.g., sheet iron. The prepared surface should be spaced from the aerial array by a horizontal distance h tan e, in which h is the height of the aerial array above the ground and e is the angle of incidence of the ground-reflected radiation. The Specification includes a mathematical discussion of the problem.
