Patent GB-931608-A (GB)
Title: Improvements relating to nuclear reactors
Inventor: MARSHALL FRANK
IPC: G21C17/00
Filed: 1960-11-23
Abstract: 931,608. Nuclear reactor power plant. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 17, 1961 [Nov. 23, 1960], No. 40354/60. Class 39 (4). A heterogeneous nuclear reactor has a number of fluid coolant pressure circuits each with inlet and outlet valves, each circuit being provided, at a point downstream near the outlet valve, with a device sensitive to the flow velocity of the coolant, so that if the flow reaches an abnormally high velocity then the device actuates means to close both valves of the respective circuit. The blower 14 circulates the coolant gas, e.g. CO 2 , through the valve 15, reactor 11, valve 17, exit duct 16 and heatexchanger 12. The devices 18 and 19, which are upstream facing pitot-static tubes, are placed on the entry and exit ducts so that if a breach occurs in the circuit the increased velocity of the gas will be noted by at least one of these tubes and registered by at least one of the differential pressure gauges 21 and 22, which then causes the pointer 24 to bridge a pair of resiliently mounted electrical contacts 25 which causes (a) the closing down of the valves 15 and 17 by means of the outputs 27 and 28; (b) the output 29 to render the other units non-actuable by the connected contact pairs, thus isolating the affected circuit; and (c) the shut down of the reactor over the output 30. The valves may also be operated manually.

Title: Hypodermic syringe
IPC: A61M5/24
Filed: 1970-08-21
Abstract: 1327212 Hypodermic syringe PHILIPS GLOEILAMPENFABRIEKEN NV 21 Aug 1970 [25 Aug 1969] 40461/70 Heading A5R A hypodermic syringe comprises an assembly of a liquid container 4 and a needle 5 which is slidable in an elongate two part housing 2, 3, the lower part 2 being penetrable by the needle, and the upper part 3 having a diameter transition 24 which enables the force exerted by an operating mechanism on the liquid container to be transferred to a piston 7, the container thus ejecting liquid through the needle. In operation, after the removal of a cap 17 and pin 16, the sleeve 14 is depressed relative to the housing 3, causing the bevelled ends 12 of fingers 11 to be nipped together in a bore in the sleeve 14. The ends 12 then slip into the housing 3 under the action of compression spring 9, by which a pressure member 8 pushes the liquid container 4 along the inside of the housing 3. Resilient lugs 20 on the pressure member 8 bear against the wall 22 of the liquid container, and engage grooves in the wall of the housing 3 until the diameter change 24 of the grooves forces the lugs radially inwards to act upon the piston 7 of the liquid container, which causes a seal 6 to burst and liquid to flow through needle 5. When the diameter transition 24 is reached, the needle penetrated the lower part of the housing 2. A seal 25 separtes the housing parts 2 and 3 and maintains the needle in a sterile condition before it penetrates the lower housing. The resilient lugs 20 may be replaced by resilient lugs (30) attached to the piston (Fig. 2, not shown) or by annular segments (40) (Fig. 3, not shown).

Title: Improvements in and relating to stamping devices
IPC: G03B17/24
Filed: 1959-12-01
Abstract: 913,247. Marking data on photographic prints. AGFA A.G. Dec. 1, 1959 [Dec. 13, 1958], No. 40848/59. Class 98 (2). [Also in Group XVI] Sheets such as photographic prints or enlargements have printed thereon particulars relating to the operation performed on them by a stamping head which prints through an ink ribbon, the stamping head having fixed characters thereon, and a movable printing element which is so controlled electrically that it can be moved relatively to the fixed characters to a selected printing position. As shown in Fig. 1, the head has eleven fixed characters 5 arranged in a circle and the movable printing element is a soft iron ball 1 freely mounted in an annular groove. The characters 5 print marks 6, Fig. 6, and the ball 1 prints a mark 7 in a position determined by the energization of one of eleven electromagnets 4. The value - 3 indicated by the mark 7 signifies the density of a filter component: in modifications, the mark 7 may indicate total exposure time or light intensity. The head comprises an annular pole member 2 and pole disc 3, magnets 4 each consisting of a winding 8 and core 9, a Z-shaped member 17, a screw-threaded sleeve 19, and upper discs receiving the leads 27a, 27b for the windings 8, and the whole is held together by a central screw 20 and nuts 21, 28. The arrangement is such that, when a particular magnet 4 is energized, the ball 1 moves around the annular groove to a position beneath the energized magnet. Several stamping heads can be mounted on a common plate which is reciprocated by a single solenoid to print on a photographic print or enlargement through an ink ribbon; or, the heads can be fixed, and the print and ink ribbon can be reciprocated towards the heads by a solenoid-operated baseplate. As shown in the circuit diagram in Fig. 7, four stamping heads 40 are associated with a photographic exposure apparatus. Each magnet 4 in each head is connected to a distributer 60 having an arm 43 settable by a member 47 which is hand-operated to indicate on a dial the exposure time with a particular colour filter, the total exposure time, or light intensity. When the main switch 45 is closed, solenoid 50 operates a relay 52 which closes a switch 52a for the exposure lamp 53. When the exposure is complete, the switch 52a is reversed to energize a relay 52 and switch in a motor 55 to advance the photographic paper for the next exposure, and bring the exposed portion beneath the set of stamping heads 40. The relay 53 is now actuated to switch in a master magnet 56 to effect the stamping operation.

Title: Detection without pressure transducers of the abnormal  inflation of vehicle tyres
IPC: G01L17/00
Filed: 1972-09-05
Abstract: 1406835 Monitoring wheel pressures J D SOUTHON 4 Dec 1973 [5 Sept 1972] 41027/72 Heading G1N The inflation of a tyre on a vehicles wheel is monitored by measuring the angular velocity of the wheel and comparing it with the mean angular velocity of all the wheels. If the tyre is underinflated the wheel angular velocity is higher than the mean, and vice versa. The angular velocities are measured by electromagnetic, electo-optical or switching transducers, producing pulse trains whose frequencies are proportional to the angular velocities. The mean of these frequencies is computed and the difference between each individual frequency and the mean value is used to operate an alarm when it exceeds a predetermined value for a preset minimum distance of travel. The alarm is automatically delayed by a centrifugal switch when the vehicle negotiates a curve.

Title: Apparatus for and method of aging alcoholic liquor
IPC: C12H6/02
Filed: 1977-10-04
Abstract: 1532920 Stirring liquids E KOPPELMAN 4 Oct 1977 [7 Oct 1976] 41278/77 Heading B1C [Also in Division C6] Apparatus for ageing distilled alcoholic spirits in a liquid-tight container consists essentially of a plurality of wooden conduits 12, Figs. 1 and 3, mounted in spaced relation between blocks 44, see Fig. 3, on a framework 22 of eight arms, and the interior channels of the conduits are radially connected at the top and bottom with a manifold 20 and the outwardly disposed surface of the individual wooden conduits 24 have a char layer 42, see Fig. 4. The side walls and bottom of the container may additionally be lined with charred wood 18. Relative movement between the liquor in the container and the char coating may be produced by either rotating the framework at a relatively slow rotation of the order of one to 12 revolutions per hour, the provision of a propeller or paddle-type agitator in the container, or circulation of the liquor externally of the container (Fig. 6, not shown). Vapours issuing from the conduits and manifold are taken out by a vacuum pump 88 for recovery in a separater 86 and condenser 90. Condensed ethanol-water thereby recovered is returned to the container by pump 92. Any liquid accumulation in the manifold assembly is removed through a vertical tube 93 by pump 95. Provision of a gas compresser 94 enables the differential pressure between the liquid side and vapour side of the hollow wooden conduits to be further increased using alternate cycles of suction and over-pressure, whereby the diffusion and/or breathing characteristics of the liquor may be accelerated. The temperature of the ageing liquor is regulated within a preselected range by the circulation of a heat-exchange fluid through piping 78 at the base of the container.

Abstract: 1,055,449. Stripping croupons from pig carcases; scalding and de-bristling. PANONIJA INDUSTRIJA KOZE, KRZNA I KONFEKCIJE SUBOTICA. Oct. 18, 1963 [Oct. 18, 1962], No. 41304/63. Heading A2U. In apparatus for stripping croupons from the carcases of pigs - a croupon being a strip of skin, substantially 45 cm. wide, extending along the back of a carcase from the neck to the base of the tail - the carcases are deposited, from an overhead conveyer 1, on to a table 3, from which they are grabbed, one at a time, between clamps 5 on a travelling chain conveyer 4, and carried horizontally through boiling water in a tub 2, with their croupons uppermost and above the surface of the water, so that the carcases are scalded, but the croupons are not. The unsubmerged head and tail portions of the carcases may be scalded with hot water, sprayed from tubular sprinklers 16, located along each side of the tub. An upwardly rising part of the conveyer 4, beyond guides 6, carries the carcases out of the tub and deposits them, one at a time, from the clamps into a conventional de-bristling machine 13, from which each de-bristled carcase is automatically thrown on to a table 14, where the feet are removed, the head is cleaned and an incision is made around the croupon. The carcase is then pushed on to a table 15 and oriented back lowermost, with the tail-end of the croupon directed towards a cradle 18. The carcase is then suspended, by hooks, from an overhead, travelling conveyer 17, and the tailend of the croupon is gripped by hand pliers, Fig. 2a (not shown) as the carcase is pulled through the cradle. A rounded edge of the cradle engages under the gripped tail-end of the croupon, and the whole croupon is thus stripped from the scalded, de-bristled carcase.

Abstract: 1,128,968. Tap-holders. ERICKSON TOOL CO. 18 Sept., 1967 [4 May, 1967], No. 42404/67. Heading B3N.  A self-releasing tap-holder comprises a housing 2, Fig. 3, adapted to be located in a machine spindle, a collet 41 for holding the tap 44, located in a body 6, and a drive member 8 for transmitting rotation from the housing to the collet. Drive member 8 has dogs 16 which cooperate with dogs 17 on body 6, and pins 11 in the housing co-operate with grooves 9 in member 8. A one-way clutch 46, Fig. 5, comprises a groove 47 in body 6, a pin 50 supporting a spring-urged roller 51, and a groove 52 in housing 2. In operation, housing 2 is rotated in the required direction and drives the tap through drive member 8, body 6, and collet 41. The tap is pulled into the workpiece until housing 2 engages a stop, and dogs 16, 17 are disengaged. Drive member 8 is moved forward slightly against a spring 30 until it abuts a flange 34, but pins and grooves 9, 11 are still in engagement. Accordingly, when the dogs 16, 17 are disengaged and no further torque is transmitted, spring 30 forces drive member 8 to the right, Fig. 3, thus preventing any contact between the dogs, and the drive member and housing continue to rotate. The tap is backed out of the hole by reversing the direction of rotation of housing 2, so that groove 52 rotates until it is engaged by roller 51, whereupon with the dogs disengaged, the housing rotates the collet and tap until the latter moves out of the workpiece, and a spring 19 moves body 6 to again engage the dogs.
