Title: Improvements in and relating to washing and like machines for treating textile and other goods
IPC: D06F37/00
Filed: 1939-12-19
Abstract: 534,924. Washing &c. machines. HENRICI, F. W. A. Dec. 19, 1939, No. 32517. [Class 138 (ii)] In washing and like machines for textile &c. goods employing a rotatable chamber, unloading of the tested goods is effected by applying thereover an apron secured near one end to the side of the chamber and rotating the chamber so that the goods are embraced thereby, whereupon the apron with the goods can be withdrawn through the open door of the chamber, assisted if desired by a winch. As shown, the goods 31 are treated in a rotatable chamber formed from perforated flanged plates e, f, g, h and p, q, r, s, t connected by internal projections a, b, c, d and j, k, l, m, n and closed by an arcuate door 13 sliding in curved girders 14 The chamber, which may be strengthened by channels u and divided by transverse partitions, is mounted on ball bearings to rotate within a shell 1, provided with an arcuate door 8 slidable in curved girders and formed with a channel 12b through which liquid can be fed into the shell. Curved fillet rings may be inserted at the junctions of the chamber with the ends and the transverse partitions to avoid binding of the goods. After the treatment an apron 22 is laid over the goods and detachably secured near one end by a rod 24 and clips 25 to one side of the chamber which is then rotated a turn or two thereby the goods become surrounded by the apron. The end 37, or if desired both ends, of the apron is then attached to hooks 36 on cords 35 passing to a winch drum 32 mounted on the shell and driven through gearing from a motor.

Title: Pulsed oscillator
IPC: H03K3/78
Filed: 1948-12-17
Abstract: 654,827. Pulsing carrier frequencies. STANDARD TELEPHONES & CABLES, Ltd. Dec. 17, 1948, No. 32699. Convention date, May 13. Drawings to Specification. [Class 40 (v)] An oscillator is keyed by pulses applied to its anode circuit to produce pulses of H.F. energy and a cavity resonator, e.g. an echo box, arranged to energize the oscillator between pulses, above the level of random noise voltages therein, by re-radiating energy derived from the oscillator during keying. The build-up of oscillations during keying therefore always commences at the same predetermined condition of the oscillator and the duration of H.F. pulses maintained constant. The Specification as open to inspection under Sect. 91 comprises also an auxiliary oscillator (Fig. 5, Cancelled, not shown) energized from the pulse modulator electronically, which primes the cavity resonator slightly in advance of anode voltage being applied to the main oscillator. This subject-matter does not appear in the Specification as accepted.

Title: A process for the production of concentrated washing, degreasing, wetting and emulsifying agents
IPC: F02P3/01
Filed: 1947-12-11
Abstract: Concentrated products suitable for immediate use as washing, degreasing, wetting and emulsifying agents are produced from less concentrated aqueous solutions of secondary sulphuric acid ester salts containing at least six carbon atoms by treating the initial solution with a water-soluble salt and a small proportion (not more than 10 per cent) of an organic solvent which is insoluble or substantially insoluble in the salt solution and contains one or more polar groups, or of a mixture of such solvents and separating the two layers into which the mixture forms.  Preferably, the solvent is one which boils above 100 DEG  C. and enhances the capillary-active effect of the product and the process is carried out at elevated temperature, the preferred temperature range being 50-100 DEG  C. Suitable solvents mentioned are the aliphatic and cyclic alcohols boiling above 100 DEG  C., e.g. cyclohexanol or methyl isobutyl carbinol, ketones, aldehydes and amines and suitable salts are common salt, sodium sulphate, sodium nitrate and the corresponding potassium salts.  In an example, a technical ester salt solution, prepared from a sulphation product of a C10-C18 alkene fraction, was treated with common salt and cyclohexanol.  The Specification as open to inspection under Sect. 91 comprises also the concentration of salts of other sulphuric esters and of sulphonic acids, e.g. sulpho-chlorination products of hydrocarbons, alkylated aromatic sulphonic acids and sulphuric esters of alcohols and of the products obtained by oxo synthesis. In an example, a solution of a sulphonate obtained by sulphochlorination of a gas oil is concentrated.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to microwave apparatus
Inventor: YOUNG LEO
IPC: H03B19/05
Filed: 1952-12-24
Abstract: 760,317. Waveguide accessories. DECCA RECORD CO., Ltd. Dec. 24, 1953 [Dec. 24, 1952], No. 32759/52. Class 40 (8). [Also in Group XL (c)] Dielectric material, such as barium titanate, whose dielectric constant can be controlled by means of an applied potential gradient is used to modify an incident microwave signal, means being provided for extracting from the modified signal a component of different frequency from that of the input signal. The material may be arranged in the form of a thin sheet extending across a waveguide, fired-on silver electrodes in the form of strips running parallel to the broad face of the guide being provided on each side of the sheet. Alternatively, electrodes are provided on one side only of the sheet, alternate strips being connected to a terminal at one edge of the sheet and the remainder being connected to a terminal at the opposite edge. The sheet may be built up of a number of slabs 15, Fig. 3, of dielectric material lying parallel to the broad face 16 of the guide, the interengaging surfaces being made conductive on both sides of the slabs. The slabs are staggered slightly and a small exposed strip is left non-conductive at one end of each face. The exposed conductive portions are connected to common terminals at each side of the guide. In an arrangement suitable for a circular waveguide 32, Fig. 4, the potential gradient is established between a central electrode 38 (via an insulated lead 36) and the walls of the guide. Other methods of applying the control potential are by ionized gas chambers on either side of the dielectric material or by mercury electrodes. In order to match the dielectric slab to the rest of the guide it may be arranged to slope in the direction of propagation within the guide. Alternatively a wedge or inverse wedge 52 of a material having a dielectric constant intermediate between that of the element 48 and that of the rest of the guide may be arranged in front of the element. Intermediate elements 49, 50, 51 of higher dielectric constant may be arranged between the element 48 and the matching means 52. Such elements may be made by mixing powdered titanates with polyfoam. Since the change in dielectric constant of the titanate or like dielectric material is independent of the direction of the electric field an element of the material placed in a waveguide will produce equal distortion of opposite half-cycles of the incident microwave field. If, however, a biasing voltage is applied to the element the distortion of opposite half-cycles will be different and the arrangement may be used as a detector or mixer. Alternatively, the harmonies (particularly the second harmonic) present in the distorted output may be selectively extracted from the output signal. For this purpose a waveguide dimensioned below cut-off for the unwanted frequencies may be used. Specifications 760,386, 760,387, 760,388, [Group XL (c)], and 760,389 are referred to.

Abstract: 506,894. Kinematograph apparatus. SOC. DES TELEPHONES ERICSSON. Nov. 14, 1938, No. 33104. Convention date, Oct. 24. [Class 97 (i)] A driving device for kinematograph apparatus intended to accommodate several types of film-holding reels is characterized in that the individual members for transmitting motion to the respective reel carriers have speed ratios inversely proportional to the diameters of empty reel cores to enable all the reel carriers to be driven during projection by a single slipping coupling common to all the reel carriers, and by the fact that all the reel carriers are driven for rewinding; at speeds in the same relation to each other as the winding speeds, by common driving means. In the form shown, the different spool carriers are mounted on shafts 7, 15 connected by gearing 13, 14. For forward winding the member 5 driven from the shaft 1 is clutched to the friction drive device 8. For rewinding it is clutched to the gear 9 which drives, through gears 10, 11, 12 the shafts 7, 15 at increased speeds. In an alternative form the shaft 7 is driven by an electric motor and the increased rewinding speed is obtained by reducing the circuit resistance with a switch.

Abstract: 1474276 Automatic steering control  MASCHINENFABRIK FAHR AG GOTTMADINGEN 29 July 1974 [14 Aug 1973] 33382/74 Heading G3R A self-propelled agricultural implement, e.g. a harvester, is automatically steered by a system in which a sensor of a row of plants or the borderline between reaped and unreaped crops is arranged in an electrical bridge circuit, the output of which forms a control signal for an electro-hydraulic steering mechanism having positional feedback to the bridge. The sensor 1 comprises either a spring- loaded feeler attached to a potentiometer Figs. 4, 5 (not shown) or an array of nine photo-electric devices, using light emitting diodes, photo transistors and an infrared filter, which are illustrated in Figs. 6, 7 (not shown) but not described in detail. The position feedback from steered wheel 6 is provided by potentiometer 29. Also included in the bridge 22 is a "slope" potentiometer 32, manually set to provide a steering bias when traversing sloping ground, and a pair of linked potentiometers 30, 31 operated in unison by a ground speed control lever. The latter also affects the output of hydraulic pump 62 supplying the steering gear; the combined effect is to modify the gain of the system in accordance with the set ground speed. Bridge balance is detected by device 2 which controls steering valve 4 via an amplifier 33 which is energized only when the driver's hand is away from a knob on the steering wheel. This feature is effected by a capacative detector 16 in the knob 17 coupled to a switch device 64 by a pair of coils 14, 15 on the steering column and tube respectively. It enables the driver instantly to take over control of the steering hydraulics. The bridge is supplied via master switch 34, "cutter running" switch 35 and "blades lowered" switch 36.

Title: Apparatus for separating flat bags from a pile in wrapping-up machines
IPC: B65B43/16
Filed: 1957-10-29
Abstract: 837,342. Feeding sheets. SCHWEIZERISCHE INDUSTRIE G.m.b.H. Oct. 29. 1957 [Oct. 30, 1956; April 23, 1957], No. 33749/57. Class 100(1) Flat bags in a pile are separated sequentially from the bottom of the pile by an oscillating sucker assisted by a reciprocating arm which raises the edges of the remaining bags, and by a slide which enters the pile between the bag being separated and the rest of the bags to take the weight of the pile. As shown in Fig. 2, a column 1 supports a casing 2 having a sloping base 4 slotted at 5 to allow a -sucker 7 to engage the lowermost bag 3 of a pile of bags in the casing 2. Before the sucker removes the bottom bag from the casing 2, the front ends of the bags immediately above are raised by the ledge 12 of an oscillating arm 11, and a slide 18 moves into the pile above the bottom bag to raise the pile and leave the bottom bag free. The sucker 7 swings about a pivot 8 to separate the bottom bag partially from the pile, and the front edge of the bag is then gripped by grippers 15, on a rod 14 pivoted at 16, which remove the bag completely. The ledge 12 of the arm 11 protrudes through a slot 13 in the front wall 9 of the casing 2, and serves to raise and also loosen the bags 3 at their front ends: the arm is reciprocable in a block 10, and has rack teeth engaging a pinion driven by a chain 30 from a drive casing 22. The slide 18 is supported on a bracket 17, and comprises a carriage in which rollers 21 are freely rotatably mounted to serve as a friction-free surface when moved into the pile. The rear end of the slide 18 has a toothed rack 31 engaged by a pinion 34 driven from the casing 22 by a chain 33 and suitable sprockets. The pivot 16 is also driven by chain-and-sprocket means from the casing 22 to cause the gripper rod 14 to oscillate. The reciprocating slide 18 may be replaced by an arcuate slide which oscillates in a plane parallel to the base 4 of the casing 2, and the rollers 21 replaced either by conical rollers or by freely rotatable balls. Fig. 10 shows a modified casing 2 wherein the wall 9 is cut away and has hinged thereto at 40 component 91 provided with an arm 41 bearing on a cam 42 in the block 10 which is driven from the arm 11. When the arm 11 is lowered, the part 9<SP>1</SP> is swung in a clockwise direction and ensures that the bags in the pile, when released, fall down squarely.
