Filed: 1947-07-11
Abstract: 624,928. Flexible abrasive discs. MINNESOTA MINING & MANUFACTURING CO. July 11, 1947, Nos. 18563 and 18564. Convention dates, March 16, 1942, and April 23, 1942. [Class 60] An abrasive disc comprises a number of superimposed disc members each having a number of slits extending from their peripheries inwardly toward the centre to form segmented sections adapted to be interlaced to cover all the rotationally leading edges. A sandpaper disc 2, Fig. 1, with radial slits 7 is placed on another disc 3, Fig. 2, with dog-leg slits 11, their abrasive-coated surfaces upwards, and the segments 6, 9 interlaced, Fig. 4. A similar complementary pair 19 of abrasive discs form the reverse side of a composite assembly 20, Fig. 5, so that the rotationally leading edge of each segment on either side is covered by an adjacent segment. The assembly 20 may be mounted for rotation on a spindle head 26. Various modifications are described, in one of which only three discs are used to form an assembly, other modifications dealing with various shapes of slits in the discs.

Abstract: 1502376 Fire alarms NOHMI BOSAI KOGYO CO Ltd 5 May 1975 [25 Aug 1974] 18749/75 Addition to 1485790 Heading G4N A fire sensor includes sensors OX, TH1 responsive to two different phenomena accompanying combustion and coupled to an analogue multiplier Am arranged to provide a signal dependent on the arithmetic product of the signals from the two sensors. As shown, sensor OX is responsive to CO. and comprises a semiconductor having a heater and a further electrode h. Thermistor TH1 has a smaller thermal time-constant than thermistor TH2 so that the voltage at their junction is a function of rate of change of temperature. After passing threshold devices D1, D2, ZD, the signals are applied to an analogue multiplier Am which, if the product is sufficiently large as to indicate a fire, turns on transistors T3 ... T5 which energize alarm relay N. In Fig. 1 (not shown) the CO sensor OX is replaced by a photo-electric smoke detector. The system is supposed not to respond to cigarette smoke or to the vapours from newly applied paint.

Abstract: 810,106. Phonograph recorders. DECCA RECORD CO. Ltd. June 20, 1957, June 20, 1956, No. 19150/56. Class 40 (4). Disc recording apparatus for simultaneously producing both lateral and hill-and-dale recordings in a single groove comprises two coils 12, 30 which constitute the stylus assembly together with supporting arms 15, 16 and a stylus holder 10, the supporting arms being mounted in rubber bushes 17, 18 which permit both torsional and vertical movement of the assembly relative to magnetic pole pieces 21, 22. Hill- and-dale movement of the cutting stylus 11 is determined by coil 13 of which only the horizontal portion lies in the magnetic field, while the lower part of this coil is utilized as a former for coil 12 which determines stylus movement in the lateral direction, the two coils being arranged with mutually perpendicular axes. Feedback coils 24, 31 are also provided which are externally connected to the circuits of the lateral and hill-and-dale recording systems. The feedback coils 24 are operative during lateral movement of the stylus and are provided on extensions 23 of the supporting arms 15, 16, each coil being formed in two parts as shown in Fig. 2 positioned between auxiliary pole pieces 25, 26 of the magnetic system. To avoid coupling between these coils and the hill-and. dale coil 30, the two coils 24 are connected in series opposition and their respective magnetic fields between the auxiliary pole pieces are in opposite directions. Feedback in the hill-anddale direction is effected by a coil 31 of which the horizontal conductors of one coil side only lie between auxiliary pole pieces 32, 33. These pole pieces may also be extensions of the main magnet system or alternatively may be associated with a separate permanent magnet or electromagnet. It is stated that the stylus assembly may be raised to a limited extent relatively to the magnet system so as to disengage the stylus from the recording material. Specification 807,381 is referred to.

Composite photographs; studios.-In producing composite pictures by photographing a part of the scene on a stage in front of a translucent screen upon which the remainder of the picture is projected, the translucent screen is shielded from stage light. A screen having opaque side walls 12 and roof 13 extends behind the translucent screen 11, which may be of oiled silk. In front of the screen 11 is placed a similar screen, preferably with its walls 14 angled to lie closely along the beam of light passing from the translucent screen to the camera and with its top 15 angularly adjustable about its rear edge. The stage lamps 16 are arranged so that light does not impinge directly on the translucent screen, and to prevent light being reflected thereon the inside of the shielding screens and the ground underneath at 17 and 18 are covered with black velvet. The portion of the stage beneath the front screen is also recessed at 18, and the rear wall 19 is inclined unwards. Sufficient scenery 22 is erected on the stage to hide the lower edge of the translucent screen. Specification 144,408 is referred to.

Abstract: 1422356 Organ perfusion apparatus VICKERS Ltd 18 July 1974 [19 April 1973] 19200/ 73 Heading A2D  An apparatus for storing body tissue comprises a vessel for receiving body tissue to be stored, the vessel having an inlet and an outlet for enabling liquid perfusate to enter and leave the vessel respectively, and pump means of the kind defining a pumping passageway along which liquid perfusate is forced when the pump means are operated by a source of operating power, duct means connecting the outlet to one end of the pumping passageway and the other end of the pumping passageway to the inlet to define with the interior of the vessel and pumping passageway, a fluid circuit around which perfusate can be circulated, the pump means being adapted to be disconnected from its source of operating power when the apparatus is not in use. In an alternative form of apparatus, those portions of the apparatus in the fluid circuit that come into contact with perfusate when the apparatus is in use are constructed to be detachable from those portions in the fluid circuit that do not contact liquid perfusate, so that the former portions may be discarded. A suitable apparatus is shown in Fig. 1 and comprises a vessel 1 for containing a kidney 2 supported on coarse filter 3. The vessel is provided with a lid, and inlet and outlet ducts. The outlet duct opens from the base of the vessel and is connected to the inlet duct via a reservoir 5 incorporating a fine filter 6, perfusion pump 7, heat exchanger 8, oxygenator 9, flow-rate meter 10, flow-control and throttle 11. The pump may consist of two compressible parallel tubes each provided with a non-return valve at each end. These tubes may be compressed and released in time with one another to provide a pulsing flow of perfusate; or one tube may be compressed as the other is released to provide a uniform flow. The pump power source 12, connection 19, cooling device 13, flow-control throttle 11 and part 23 of the manometer 14 are provided with plug-in connections and can accordingly be disconnected from other components, which other components are those that contact perfusate when the apparatus is in use.

A load frame 5 is suspended from two cable systems each with three cables 6, 7, 8 arranged as the edges of a symmetrical pyramid with an equilateral triangle as its base. Each set of cables 6, 7, 8 is connected to a cable 20 wound by a drum 22 so that both sets of cables 6, 7, 8 are wound equally. At their lower ends the cables 6, 7, 8 are connected to spring steel links 9, 10, 11 interconnected by six bevel gears five of which, 32, are rigidly attached to shafts 27 to which the links 9, 10, 11 are fixed, the sixth, 35, being pivoted on its journal and loaded by a spring 35. The crane can thus accelerate and retard quickly without the load swaying. In the case of very low hanging loads the cable support points on the crane may be relatively movable to improve the sway-preventing effect. A load may be suspended by one system having three cables and links.
