Title: Method of producing magnetic recording tape
IPC: G11B5/70
Filed: 1971-12-14
Abstract: 1381869 Producing coated magnetic tapes FUJI PHOTO FILM CO Ltd 14 Dec 1971 [15 Dec 1970] 58128/71 Heading B2E In a method of producing a magnetic recording tape, a 3-ply starting material is calendered through a space between a metal roller and a non-metal roller so that a magnetic layer on one surface of the base makes contact with the metal roller and a layer of greater resilience than the base makes contact with the non-metallic roller whereby surface irregularities in the non-metallic roller are compensated for and a uniform pressure between the magnetic layer and the metal roller yields a smooth magnetic surface on the tape. The resilient layer is preferably applied to the back of a magnetic tape, may be porous and consist of polyurethane containing carbon black. Alternatively it may consist of TiO 2  in synthetic rubber e.g. chlorosulphonated polyethylene. Copolymers such as ethylene-vinyl acetate copolymer mixtures may provide the resilient layer and vinyl chloride-acetate mixtures are also referred to. Porosity may be imparted by including graphite in urea-aldehyde resin and the use of cellulosic as a binder for, carbon black particles is mentioned.

Title: Method for forming and fixing loops at the ends of cables
Inventor: CESARINI JACQUES FRANCOIS
IPC: F16G11/02
Filed: 1968-12-06
Abstract: 1,256,090. Forming loops in cables; clamps. J. F. CESARINI. 6 Dec., 1968 [6 Dec., 1967], No. 58160/68. Heading D1T. A loop 2 at the end of a cable 3 is formed by clamping together the loop ends 2a and 2b in a deformable clamp 4 having part of its bore of larger diameter than the remainder so as to form a skirt 5 which houses the end face 2a' of the cable, this skirt ensuring that the pressure that is subsequently exerted on the clamp 4, to deform it into gripping relationship with the ends 2a, 2b, is not transmitted to the end face 2a' of the cable. The skirt 5 is then compressed to conical form. The smaller bore may be formed by an auxiliary sleeve screwed or otherwise fitted into an outer sleeve. If the clamp is used to connect two cables together it may have a skirt at each end. The change in diameter of the bore takes place at a face at least part of which is perpendicular to the axis of the body. The clamp 4 may have an elliptical or circular cross-section. In the latter case the loop ends are formed into semicylindrical cross-sections or the ends 2a and 2b are spliced together.

Title: Compression-condensation temperature control system
IPC: F25B41/04
Filed: 1969-12-23
Abstract: 1300569 Refrigeration AMERICAN AIR FILTER CO Inc 23 Dec 1969 [26 Dec 1968] 62671/69 Headings F4H and F4V Air is cooled by passage through the evaporator 35 of a compression-condensation system and is then partially reheated to a desired temperature by passage through a heat exchanger 59 which is supplied with hot gas from the compressor 15. Hot gas passes through lines 39 and 49 to a reservoir 51 which is kept at constant pressure by a valve PCV-1. A valve TCV-1, acting in response to air temperature, controls flow of hot gas from the reservoir 51 to the heat exchanger 59. The system includes a compressor protection by-pass having a pressure responsive valve PCV-2 which, in the event of too low a suction pressure occurring, opens to allow flow from the reservoir 51 through a check valve CKV-1, or from the line 39 through a regulator SOL-1, into the compressor suction line 13. A pressure switch PS-1 switches the compressor off if the suction pressure becomes dangerously low. A valve TX-2 may be included to guard against the attainment of excessively high temperatures in the compressor suction line. The expansion valve 31 operates in response to temperature and pressure in the suction line. The air stream which has passed over the evaporator 35 and reheater 59 has a reliably constant temperature and is used in the air conditioning of a clean room. If finer temperature control is required, a second reheater may be located downstream of the reheater 59 and may be heated by steam, water or electricity.
Patent GB-773246-A (GB)
Abstract: 773,246. Cash registers. STYNER, F., and CHLOUBA, A. Feb. 28, 1955 [March 13, 1954], No. 5815/55. Class 106(1). Zeros are eliminated from the higher order item indication by means which return higher order zero-arrested differential members to an initial sub-zero position, the item indicators having a blank indicating position below the zero position and to which they are returned at the commencement of each cycle. Key-set stop bars 38 are actuated by levers 27 when released to springs 29 upon downward movement of a bail 31 under control of a main cam 34, the differential movement of the levers 27, during their subsequent return upward movement by the bail 31, being transmitted through intermeshing gears 24 and 13 to item indicating drums 6. The drums 6 and gears 13, loose on their spindle 14, are mounted in a frame 20 which, at the commencement of each cycle, is raised by cam arms 23 to disengage the gears 13 and 24 during the downward movement of the levers 27. The shaft 14 is oscillated, whilst the gears 13 and 24 are disengaged, and ears 18 on the shaft engage studs 17 on the gears 13 to reset the gears and drums 6. According to the invention, the drums, when reset, present blank areas below their zero markings to the viewer, whilst the stop bars 38 correspondingly are adapted to move one step more than the digital markings of the item keys 35, the zero stop levers 43 being located a full digital step from their coacting studs 44 on the stop bars when in their initial positions. After the levers 27 have completed their downward movement, spring-actuated pawls 51 carried by arms 53 are moved forwardly under control of a main cam 58, entering notches 50 in any stop bars 38 arrested in zero position and returning these stop bars to their initial sub-zero position. Each pawl 51, however, has a lateral arm 60 underlying the pawl of next higher order so that all the pawls 51 below the highest set order are blocked against entering the notches 50 and zero set stop bars in these lower orders remain in zero position. When, therefore, the levers 27 and stop bars are restored by the bail 31, the drums 6 of the higher unset orders remain in their sub-zero or blank positions whilst zeros are correctly shown in the lower orders. Pawls 51 are omitted from decimal fraction orders so that zeros are always indicated in these orders.

Patent GB-2018579-A (GB)
Title: Coffee infusion
IPC: A23F5/26
Filed: 1979-03-29
Abstract: Flavour is extracted from coffee solids by passing a liquid through the solids supported on a filter or sieve. The liquid is passed through the solids under pressure, preferably produced by an inert gas. This is carried out at a temperature below the boiling point of water. A high degree of extraction is achieved without loss of quality due to oxidation of the components of the coffee solids. An inert gas, such as carbon dioxide, can be dissolved in water and this solution used as the liquid which is to become the coffee beverage; in this case the solution is simply heated to release the inert gas and to generate the required pressure.
