Title: Power output regulating device for internal combustion engines
IPC: F02D31/00
Filed: 1963-12-23
Abstract: 1,031,597. Regulating I.C. engines; rotary piston internal combustion engines. FICHTEL & SACHS A.G. Dec. 23, 1963 [Jan. 19, 1963], No. 50715/63. Headings F1B and F1F. [Also in Division G3] In an I.C. engine power output regulating device, a slide valve 4, Fig. 2, rotating with shaft 2, Fig. 1 (not shown), is guided for radial movement so that when a specific rotational speed is reached the preload of a spring 9 is overcome by the centrifugal force acting on the slide valve which then reduces the flow cross section of the induction port, an air gap 11 being arranged between the non-rotating parts of the induction passage and the slide valve. The slide valve 4 is secured to crank-shaft cheeck 16 by bolts 5, Fig. 2, which engage in slots 6. Induction gas passes through diaphragm valve 13 and into the crankcase through port 15. The device may be applied to I.C. engines having piston-controlled scavenge ports, to valve-controlled I.C. engines or to rotary-piston I.C. engines.

[Class 2 (iii)] Tetrahydrofuranes are prepared by heating 1.4 butylene glycol or its C-alkyl, aralkyl, cyclo. alkyl or aryl substitution products in the liquid, state with one or more of the solid dehydration catalysts hereinafter specified to such a temperature that the tetrahydrofurane and water distil off.. The catalysts used are oxides of aluminium, zirconium or thorium, sulphates of aluminium and copper, potassium aluminium sulphate, potassium pyrosulphate, phosphates of aluminium, iron, cerium and silver having a neutral reaction, chlorides of magnesium, calcium, zinc and aluminium, silica gel, bleaching earths, organic acids, e.g. oxalic or. p-toluene sulphonic, and. acid anhydrides. The tetrahydrofuranes may be obtained by fractional distillation with or without previous drying. Aqueous solutions of 1.4 butylene glycol, obtained by hydrogenation of butene.2-diol- 1.4 in aqueous solution, may be used. In examples, the glycol is heated with anhydrous chlorides of Al, Zn, Mg, and Ca, p-toluene sulphonic acid, oxalic acid, succinic or maleic anhydride, sulphates of Cu and AI, potassium aluminium sulphate, potassium pyrosulphate, active aluminium oxide, and bauxite, at temperatures 'which vary from 126-205‹ C.

Title: Data Processing Apparatus
IPC: G06F12/08
Filed: 1967-11-09
Abstract: 1,193,719. Computers; storage. INTERNATIONAL BUSINESS MACHINES CORP. 9 Nov., 1967 [10 Nov., 1966], No. 50931/67. Heading G4A and G4C. In a data processing system, bulk storage blocks a data fetch request relating to highspeed storage if granting it would result in data from high-speed storage occupying data transfer means when required for bulk storage data. In a data processing system, a bus control unit grants access requests from I/O channels and CPU for high-speed storage units and bulk storage units one at a time on a priority basis, requests for those units which are busy being ignored in the priority determination. Accesses to given storage units can be started and before they have delivered their data accesses to further units can be started. When an accessed bulk storage unit is ready to deliver its data it prevents the bus control unit granting any further high-speed storage access requests. Some bulk storage units may be shared between a plurality of such data processing systems. Reference is made to Specification 1,193,720.
Patent GB-1529369-A (GB)
Title: Die closing unit with retractable tie rods
IPC: B22D17/26
Filed: 1975-12-12
Abstract: The mould-closing unit has bars (20) which pass through a movable mould half (30, 31), a fixed mould half (28, 29), platens (11, 12) and a frame plate (13). The bars (20) are connected releasably to the fixed platen (11) and the frame plate (13). To change the mould (28-31), the bars (20) can be pulled out of the mould parts (28-31). As a result, the useful area for the mould is larger than in the case of closing units where the moulds have to pass through the opening bounded by the fixed bars in order to be changed. For removal, the bars (20) can be connected to clamps (23) fixed to the movable platen (12). <IMAGE>

Title: Improvements in or relating to multi-layer circuit boards
IPC: H01R12/51
Filed: 1965-12-16
Abstract: 1,111,088. Printed circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. 16 Dec., 1965 [24 Dec., 1964], No. 53366/65. Heading H1R. In a multilayer printed circuit board of the kind in which selected conductive patterns at different levels are interconnected by means of metallized (e.g. electro-plated) holes through the board which intersect said patterns, the internal conductive patterns are formed so as to extend to predetermined distances from axes on which the holes are subsequently drilled, and each hole is of such a diameter that it intersects only those internal patterns which it is desired to interconnect at that axis. Thus, in Fig. 3, the internal conductive patterns formed on insulating (e.g. epoxy glass) substrates 15, 16, 17 comprise, at the left hand axis, a large void, a small void, and a large void respectively, so that when a large hole 20 is drilled on that axis, it intersects only the middle internal pattern. At the right hand axis, the top internal pattern has a small void, the bottom internal pattern has a large void, while the middle pattern has an " arcuate void " (30, Fig. 2, not shown), which means that the conductive material extends to the axis but is partially removed (as by etching) around the axis at a predetermined distance therefrom; a small hole 22 drilled on the axis intersects only the middle pattern. At some axes two semi-circular voids, one large, the other small, may be formed in selected patterns, and adjacent voids may have etched paths between them. To achieve selective intersection, holes may be stepped or conically tapered (Fig. 6, not shown).

Abstract: 1482764 Baling presses LUMMUS INDUSTRIES Inc 19 Dec 1974 [19 Dec 1973] 54945/74 Heading B5F An apparatus for baling fibres such as cotton and man-made fibres comprises a pair of platens 13, 14 of which the movable platen 13 has an associated pressure sensor 33 and a position sensor 35 to stop the apparatus when the fibres are pressed to a predetermined value and/or when the platen is within a predetermined range, i.e. the shut-height of the apparatus. The platens have guides 41, 43, Fig. 3, for strapping fed from a strapping device 46. The guide 41 on the movable platen 13 has a wide mouth 42 to allow strapping to be fed to the guide at all the various stopping positions of the platen. The platen 13 is moved by a hydraulic cylinder 11 whose pressure is sensed by a pressure sensor 33 which de-energizes a solenoid 31 to operate a valve 27 and stop the apparatus when the predetermined pressure is reached. If the apparatus does not reach the predetermined pressure the platen 13 will continue to rise until the switch arm 35 runs off the end of a control rod 36 fixed to the movable platen. The arm 35 actuates a switch 38 to trigger the strapping device 46 and also stop the apparatus. If too much fibre is fed between the platens pressure sensors 33 and 34 are actuated before the maximum shut-height is reached to stop the apparatus and prevent it being overstressed. The strapping then has to be performed manually.
