Title: Improvements relating to the preparation of textile fibrous materials for spinning
Inventor: NUTTER WALTER
IPC: D01G23/08
Filed: 1960-01-15
Abstract: 910,759. Preparing fibres for spinning. T.M.M. (RESEARCH) Ltd. Jan. 3, 1961 [Jan. 15, 1960], No. 1577/60. Classes 120 (1), 120 (2) and 120 (3). Apparatus for preparing fibres for spinning includes a battery of carding machines and means for continuously drafting and combining a plurality of the drafted slivers delivered by these machines, the feed and/or delivery elements of the latter being positively driven at identical speeds. The main cylinders of the carding machines are driven from a power source separate from that for the feed and delivery elements and preferably independently. The doffers may be driven from a common line shaft and the doffer drive is transmitted to the feed roller of each machine. The supply of fibres from the blowroom to the carding machines is through a pneumatic conveyer BR that discharges into a reservoir R from which a further pneumatic conveyer PC delivers to a belt conveyer MC from which the fibres are swept laterally by adjustable paddles P into shoots CH that may be provided with vibrating walls pierced with bleed holes. Instruments sensitive to the head of fibres in the reservoir R control delivery to it. Condenser and fan units are represented at CF1 and CF2. Slivers emerging from the carding machines are collected upon a railway head delivery table RH for drafting and delivery as a single sliver at the draw frame DB. Although circular cans may be used, cans may be of rectangular plan divided into several compartments and mounted to be indexed to sliver receiving position. Instead of forming a sliver, the draw frame DB may be arranged to deliver laps for creeling at a combing machine. If a blockage occurs in the conveyer system the electric motors actuating the system will stop, but the conveyers are arranged to continue operation when carding machines are inoperative. The feed elements and doffers of the carding machines CM, the draw frame DB and the coiler CO are driven by a common electric motor through clutches and variable-speed units. If a motor driving a carding machine were to fail, an electrically controlled clutch would stop the whole of the delivery part of the plant. Individual sliver stop motions are provided on the railway head table, between each carding machine and the railway head, and between the draw frame and the coiler.
Patent GB-1022559-A (GB)
Title: Foamed synthetic resins and method and apparatus for producing the same
Inventor: VOISINET WALTER EUGENE
IPC: B29C44/58
Filed: 1964-01-14
Abstract: A cellular foaming synthetic resin is expanded by relieving the pressure from foaming by allowing an upward, substantially vertical expansion of the foaming mass, relieving further the internal pressure by a substantially horizontal expansion occurring prior to the exhaustion of the expansive energy of the foaming resin in undergoing vertical rise, thus producing a block of synthetic resin foam which has been expanded along at least two substantially perpendicular axes.  The foam is allowed to expand in a vertical direction to a predetermined height then in a horizontal direction until the required density is obtained, and thereafter the resin is allowed to attain self-supporting consistency.  The foaming process can be brought about in an apparatus which allows relatively greater horizontal expansion nearer the bottom than the top.  The synthetic resin preferred is a polyurethane.  The product of the process has uniform strength and compressive yield strength characteristics along the three directional axes.  Building panels can be made from the foam material.

Title: Improvements in or relating to train control and/or cab signalling systems
IPC: B61L3/00
Filed: 1931-01-20
Abstract: 371,368. Signals on trains controlled from the track. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A., and HUDD, A. E., Glenbervie, Long Park, Chesham Bois, Buckinghamshire. Jan. 20, 1931, No. 1900. [Class 105.] In a train control and cab signalling system in which locomotive apparatus is actuated and restored by magnets located along the track, the restoration is delayed by means of an auxiliary device for a predetermined time after the receipt of the restoring influence. For example, with the locomotive apparatus described in Specification 353,502, in which the track magnets act to vent and then to close a pipe 1 so that the brake and audible signal pipe connection 2 is vented and the vacuum then only slowly restored through a restricted orifice 4 in the connection 3 from the train reservoir, the restoration of the vacuum is further delayed by means of a valve 8 and reservoir 10 normally open to the atmosphere by a port 11 but having a second port 12 which communicates with the piping when the valve 8 is lifted by the spring 9 on the venting of pipe 1. The extra capacity of the reservoir 10 delays the building up of vacuum ; when the vacuum is sufficient the valve 8 is restored to shut off the reservoir 10 from the piping 1 and to reconnect it to atmosphere.
