Title: Balancing apparatus
IPC: G01M1/22
Filed: 1963-06-11
Abstract: 1,042,623. Automatic balancing. KISTLER INSTRUMENTS A.G. June 11, 1963 [June 18, 1962; July 27, 1962; Feb.20, 1963], No. 23178/63. Heading G3R. In a system for automatically balancing a body, a portable detector, attached to a machine by which the body is rotated, responds to unbalance by mechanical resonance producing electrical signals which control a portable electromagnetic tool actuator, attached to the machine by which the body is rotated, so that the body is balanced by periodic operation of the tool to remove material from a portion of the periphery of the body. As described, the detector, which may be mounted on the bearing for the rotating body, is a magnet at the end of an adjustable reed so that mechanical resonance causes it to vibrate relative to a coil the output of which is amplified, modified by logarithmic feedback, and applied to a Schmitt-trigger circuit producing a rectangular pulse output for application to the tool actuator. The latter is located around the axis of rotation of the body in such a position relative to the detector as to allow for the time constant of the control system. The detector may, alternatively, be mounted on the bed of the machine and a phase shifter introduced into the circuit to allow for the time constant of the system.

Title: Improvements relating to the coating of plastic material
Inventor: DEAKIN STANLEY THOMAS
IPC: B32B15/08
Filed: 1953-08-25
Abstract: In a process of coating a plastic material, e.g. P.T.F.E. or thermosetting plastics such as silicon resins, with metal, the plastic in powder, granulated or other finely divided state is compressed to form a block, sheet or other preformed shape, the shaped material is surfaced with a metallic coating so as to cause the metal to key into the spaces between the plastic particles, the coated material is further compressed to mould it more closely to the required dimensions and is then heattreated.  The metal may be copper or brass and it may serve as a base for further coatings, applied by soldering or electroplating, of the same or different metals. Metallized P.T.F.E. electrical bushings may be made by forming the powdered P.T.F.E. in a press, coating with metal by sputtering, vaporization or spraying, applying further compression, heating at 320 DEG -400 DEG C., preferably 327 DEG C., and allowing the block to cool under pressure in the mould.  The process may also be applied to the manufacture of printed circuits, resistors, coils, capacitances and base membars for thermionic valves.  Specification 649,593 [Group XXXVI] is referred to.

Title: Improvements in or relating to a flexible casing for use with the core of a push-pull cable assembly
IPC: F16C1/26
Filed: 1955-08-15
Abstract: 785,145. Bowden mechanism. MORSE, J. F. Aug. 15, 1955, No. 23480/55. Class 80 (3). The outer casing 5 for a push-pull cable 1 comprises a flattened wire ribbon 36 wrapped in a tight coil and covered by a sheath 38 of rubber or the like with an outer spiral wire wrapping 40. The wires 40 have a permanent set and, though closely spaced, are not in actual contact. The edges of the ribbon 36 are rounded, the common tangent at point of contact between adjacent turns being normal to the axis of the casing. The casing is clamped in an end fitting 20 by the skirt 54 of a ring which is forced into a conical socket in a member 25 by tightening a threaded member 45. The skirt 54 is preferably split and its edge is sharpened to dig into the wires 40. The cable 1 preferably comprises spirallywrapped wire strands 2 covered by a helix of flat metal ribbon. It passes through a guide tube 16 slidable in a sleeve 18a and is clamped in a fitting 10 pivoted to an operating lever 15. If the end fitting 20 is rigidly supported, the sleeve 18a has a spherical head 28 received in a socket in the fitting 20 to allow pivotal movement of the fitting 10. If the fitting 20 is not rigidly supported, the sleeve 18 is rigidly secured to the fitting 20 and the pivotal movement is accommodated by flexing of the casing 5. The casing 5 will not tend to unravel when out and the sheath 38 renders it oil and water-tight. Moreover the sheath 38 yields to prevent crushing of the ribbon 36 when the wires 40 are contracted, e.g. by the clamping ring 54, or by receiving a knock. For this reason only a small clearance is needed between the cable 1 and casing 5.

Title: Improvements in or relating to material adding devices for automatic beam weighing scales
IPC: G01G21/00
Filed: 1938-08-11
Abstract: 501,117. Delivering vehicles from shoots. HESSER MASCHINENFABRIK AKT.-GES., F. Aug. 11, 1938, No. 23690. Convention date, Sept. 1, 1937. [Class 78 (i)] [Also in Group XVIII] In an automatic scale for weighing out cube sugar or other pieces wherein a pre-loading device acting on the scale beam prevents an over-load weighing, a pendulum balance measures the shortage and a selective closure of electric contacts (instead of operating indicators as previously to inform the attendant of the number of pieces of sugar to be added manually) controls the energization of magnets associated with an automatic device for feeding the pieces to stop devices which are actuated by the selected magnets to liberate the corresponding pieces. As shown, the packet P which has previously received an under-weight of sugar at the weighing station has its weight made up by one or more pieces z of sugar supplied to a shoot 20 by a conveyer 1 intermittently advanced by a rod 17 and ratchet pawl 16. The shoot 20 holds several columns of pieces z and each column is prevented from sliding down the shoot by a stop lever 27 and leaf spring 35. The stop levers are withdrawn by magnets 33 connected by a remote control device of known kind to the electric contacts referred to above, the number of these contacts selectively closed by the movement . of the scale beam being equal to the number of sugar pieces to be added. The energized magnets 33 thus selectively energized each allow the foremost sugar piece to pass into the packet, the remainder of the sugar column being retained by the leaf spring 35. When the magnets are de-energized the stop levers return and the push-rod 17 descends to allow a lever 41 and the leaf springs 35 to liberate the sugar columns which then slide down to the stop levers. The return of the push-rod feeds the sugar pieces from the conveyer 1 to make up the deficit on the shoot. German Specification 661,249 is referred to.

Abstract: 1,113,261. Distillation of water in association with steam turbine plant. ASAHI GLASS CO. Ltd. 3 June, 1965 [8 June, 1964], No. 23775/65. Heading BIB. [Also in Division F1 Steam discharge from the final stage of a turbine is used to boil saline water in a distillation plant maintained under sub-atmospheric pressure, the operating conditions of the turbine being such that the pressure h<SP>1</SP> of the steam discharged from it is not more than 250 mm. greater than the pressure maintained in the condenser of the distillation plant. The distillation plant may be associated with an electrical power installation, the distillation being carried out at off-peak periods of power production. In an example, h<SP>1</SP> is increased from 38 to 107 mm.Hg when the distillation plant is in operation. As shown, steam discharge from the final stage of turbine T is led to the first effect VE1 of a double-effect evaporator. Saline water to be distilled is used as cooling-medium in condenser C, and is then supplied to the second effect VE2. Steam is tapped off from intermediate stages of the turbine and used to preheat water,_withdrawn from the heating-chamber of evaporator VE1, before the water is introduced into the boiler which supplies steam to the turbine. The number of effects of the evaporator may be altered, the number being dependent on the excess power available.

Title: Apparatus for simultaneously locking or releasing railway carriage or other doors arranged in series
IPC: E05B65/36
Filed: 1921-09-08
Abstract: 184,391. Stone, A., and Digger, I. T. Sept. 8, 1921. Fastenings operated mechanically from a distance.-Catches on railway-carriage doors are engaged by a pivoted catch on the roof of the carriage and released by a weight acting on the tail end of the lever and normally supported by a cord or wire, extending from the guard's van. In one form, Fig. 3, the catch a engages the enlarged head d of a lever e pivoted at f on the roof. When the guard slackens a cord or wire passing through holes i in weights h sliding on rods g adjacent to each lever e, the weight h drops on the tail end of the lever and disengages its head from the door catch a. In another form, Fig. 5, the weighted member for rocking the lever e to release the door consists of a member l pivoted on the same pivot as the lever e and having a weighted end m through which passes the cord. On releasing the cord. the weighted end m drops on the tail end k of the lever e and releases the door. In the preferred form, Figs. 7 and 8, the device is secured along the edge of the roof in order to avoid the necessity of adapting the curvature of the plate o of the previous forms to suit the curvature of different roofs. The catch a on the door engages the lever e which is pivoted parallel to the edge of the carriage at f, by means of its bevelled head c<1> and the bevel g<1> on the lever e. The lever l is pivoted to the lever e and its weighted end is held up by a short cord sattached to the operating cord j, which, when released, allows the lever l to fall and disengage the lever e from the catch a. The base-plate o is flat and has an abutment r which prevents the lever e from being bent when pressure is applied to the door in its fastened position.
