Title: Apparatus for filling bottles with a powder
IPC: B65B1/36
Filed: 1969-02-21
Abstract: 1,206,254. Filling bottles with powder. RHONE-POULENC S.A. 21 Feb., 1969 [22 Feb., 1968], No. 9617/69. Heading B8C. A bottle-filling machine comprises a plate 16, Fig. 2, rotatable about a vertical axis (shaft 2) and formed with a number of radial grooves 17, means 19, 20 for filling the grooves with powder, and a pusher plate 10 associated with each groove and adapted to be lowered into the groove at a predetermined position along the latter's length and then moved radially outwardly to move a corresponding amount of powder from the groove, through a funnel 18 and into a bottle 15. Radial movement of the plates 10 is effected by a stationary cam 13 acting through members 23, 40, 21 (see also Fig. 8). Vertical movement of plates 10 derives from push-rods 9 moving over annular cam tracks 7, 8. The angular position of track 8 is adjustable (by means 42-45) to adjust the radial position at which each plate 10 drops into the corresponding groove 17. Push-rods 9 and further push-rods 4 extend through bores in members 6 and 14, which rotate with plate 16. Rotary tables (25, Fig. 1) and 26 feed empty bottles to and remove full bottles from the machine. Each bottle 15 is held up against its corresponding funnel 18 by a push-rod 4, which moves over a stationary annular cam track 3. The push-rods 4 and 9 are each of telescopic construction, Fig. 8, and spring- urged to their extended position. If, during operation of the machine, no bottle is fed to the position immediately above a particular pushrod 4, then the top of that rod moves up above its normal bottle-engaging position to the position shown in Fig. 8. A finger 28 is thus urged out of an annular recess 27 in rod 4 and into a recess 29 in corresponding push-rod 9 to prevent lifting of plate 10. Moreover, a lug 38 is not lifted out of a recess 39 so that no radial movement is imparted to the plate 10. Thus no powder is fed through a funnel 18 if no bottle is located therebeneath.

Title: Low power electric resistance heating element and method of manufacturing same
IPC: H05B3/28
Filed: 1937-04-06
Abstract: 471,476. Electric wire resistances. CHALLET, E. April 6, 1937, No. 9746. Convention date, April 6, 1936. [Class 39 (iii)] In an electric heating element the heating resistance is completely embedded and held against displacement in a cushion formed of glass wool or slag wool. In the manufacture of the element the resistance wire 4 is forced down on the cushion 3 by a press 6. A strong current is then passed through the wire to heat it to incandescence and soften the parts of the cushion contacting therewith. The resistance is then forced into the cushion by the press. The wire is held against displacement by the cushion as the currents used in normal working produce only low temperatures which do not soften the slag wool. The element may be used as a heating panel.

Title: Improvements in or relating to metal meshes suitable for use in television transmitting tubes
IPC: H01J29/41
Filed: 1945-04-18
Abstract: A method of applying an insulating coating to electrical conductors such as metal meshes in television transmitting tubes comprises wetting the conductor with a solution of a hydrolysable silica compound and hydrolysing the compound so leaving a film of silica on the conductor.  The conductor may be of aluminium already insulated with a layer of aluminium oxide.  Suitable silica compounds are silicon tetrachloride and silicon esters which may be hydrolysed in the vapour of hydrochloric acid, nitric acid or ammonia, but preferably those esters which are hydrolysed on exposure to air.  As an example, an acetone solution of ethyl orthosilicate is applied to a mesh by spraying or dipping, the acetone being allowed to evaporate, leaving pure silica after exposure.  Several applications may be made in which case the mesh may be baked between the applications.  U.S.A. Specification 2,027,931 is referred to.

Title: Process for reuse of polyester resin
IPC: C08G63/00
Filed: 1969-02-25
Abstract: 1,254,209. Reuse of polyester resin. GOODYEAR TIRE & RUBBER CO. 25 Feb., 1969 [22 March, 1968], No. 9915/69. Heading C3R. A high molecular weight linear polyester resin is partially depolymerized by mixing with it one or more of water, glycols, dicarboxylic acids and phenyl, methyl, ethyl or propyl esters of dicarboxylic acids in an extrusion apparatus, heating and mixing vigorously the mixture formed under superatmospheric pressure to induce a degradation reaction, and extruding the degraded polyester. Preferably the polyester is mixed with 0-015 to 0-047 mol of reclaiming agent per mol of acid units in the polyester resin, and the pressure used is from 20 to 300 p.s.i. gauge. The resulting low molecular weight polyester preferably has an average degree of polymerization of 20 to 30. When the polyester resin is polyethylene terephthalate, the reclaiming agent may be water, ethylene glycol, terephthalic acid or dimethyl terephthalate, in which case the low molecular weight polyester produced will be a homopolyester. A copolyester may be produced by using as reclaiming agent acids or glycols other than those from which the polyester resin is derived. The low molecular weight resin produced by the process of the invention may be added to newly formed polyester resin prepolymer and condensed to form high molecular weight polyester resin.

Patent HK-103794-A (HK)
Title: Optical ranging by phase shift measurement
Inventor: MILLER GABRIEL L
IPC: H03G3/20
Filed: 1994-09-29
Abstract: There is disclosed an optical ranging system adapted for use with widely varying return signal levels. Automatic signal level control is achieved in two parts, a passive optical part and an active electronic AGC part. The optical part is based on the coaxial arrangement of transmitting and receiving elements in which the shielded transmitting element is mounted in front of the receiving element, which includes a Fresnel lens which comprises a plastic casting. The electronic AGC portion of the system includes means for providing a voltage drive (with low internal impedance) for the final AGC transistor when it would tend to be slow, so little phase shift in the control results from changes in the signal levels. Thereby, the determination of distance (the ranging) by phase shift measurement is kept reliable as signal level changes. This optical ranging system is especially adapted for mounting on autonomously guided vehicles (robot carts), which are important for material handling and inventory control in manufacturing system in factory environments.
