Title: Improvements in or relating to electrical condensers
IPC: H01G5/06
Filed: 1927-09-24
Abstract: 301,586. Igranic Electric Co., Ltd., Curtis, A. H., and Holbeach, W. M. Sept. 24, 1927. Condensers have their plates mounted transversely upon a common rod by forming the rod with a number of sets of slots, the slots of each set being in a common transverse plane, forming the plates with corresponding holes, passing the rod through the hole of each plate until a set of slots is in registration with the hole, and then turning the rod. The formation of the holes and slots is such that the engagement is effected with a wedging action. The vanes 1 are formed with equilateral triangular holes a adapted to receive rods 2 of corresponding section formed with sets of slots b, the bases of which lie on the inscribed circle. The rods are turned so that the edges of the holes a rest tangentially on the bases of the slots and are gripped by means of a taper of the slots down to a thickness at the base less than that of the vanes. The bases may vary slightly from the circle so as to jam the edges of the holes a. The cross-section may be oval or a straight-sided figure, in the latter case at least three elements of its perimeter being tangent to the inscribed circle. With circular section rods, circular holes in the plates have a narrow extension the edges of which engage opposite slots in the rod when the rod is passed through the hole and moved laterally.

Title: Improvements in and relating to the treatment of cellulosic materials
IPC: D06M15/05
Filed: 1935-09-16
Abstract: Cellulosic fabrics are treated with a solution of regenerated cellulose, modified cellulose or a cellulose ether or mixtures thereof in caustic alkali, and then mercerized with caustic alkali. The cellulosic solution may contain fillers or colouring matter or both, and it may be applied in the form of a pattern. The cellulose or cellulose ether may be precipitated by removal of the alkali before mercerization.  Suitable ethers are alkali-soluble methyl cellulose or glycol cellulose.  When an open weave cotton fabric is treated the effect is an organdie finish; with closely woven fabrics a linen effect is obtained.  In examples: (1) a cotton fabric is padded in a solution of 2--5 per cent glycol cellulose in dilute caustic soda (5--10 per cent strength), soured, washed and mercerized; (2) an unbleached cotton fabric is impregnated with 5 per cent of modified cellulose in 10 per cent caustic soda, then treated with milk of lime and boiled, bleached and mercerized.

Title: Continuously variable electric motor change speed gear
IPC: H02K7/10
Filed: 1947-09-19
Abstract: 647,909. Variable-speed gearing. WULLSCHLEGER, A. Sept. 19 1947, No. 25627. Convention date, June 15. 1945. [Class 80(ii)] [Also in Group XXXV] Stepless torward or reverse variable speed is obtainable from the rotatably mounted stator or field and rotor or armature of an electric motor, connection between these parts being made through a countershaft by two belts, one adjustably running on conical pulleys, and by an epicyclic gearing. A motor part 2a is fast on a shaft 7 mounted in bearings 12, 13, and a motor part 2, housed in a conical pulley 1, is rotatably mounted on the shaft 7 by bearings 8, 8a, brush holders and slip rings 3-6 supplying current to the motor windings. A wedge belt 18 conveys a fixed ratio drive from a pulley 9 on the shaft 7 to a pulley 21 on the countershaft 19, and an axially movable belt 17 conveys a variable ratio drive from a conical pulley 20 on the countershaft to the oppositely inclined conical pulley 1, the said countershaft being mounted in bearings 15, 16 slidably carried in slots (not shown) of a frame 14 to tension the belts. A planet 24, rotatably secured to the pulley 1, meshes with a pinion 10 fast on the shaft 7 and with an internally toothed annulus gear 11a on the output shaft 11c. The variation of output speed and direction is obtained by varying the axial position'of the belt 17, by crossing either of the two belts, and by pole and phase changing of the motor.

Patent GB-298224-A (GB)
Title: Improvements in or relating to the supply of filament-heating current to the thermionic valves of radio receivers or the like
IPC: H04B1/16
Filed: 1928-09-07
Abstract: 298,224. Fansteel Products Co., Inc., (Assignees of Danley, W. E.). Oct. 6, 1927, [Convention date]. Thermionic generators, amplifiers, and detectors.-The filament circuits of the valves of a radio receiver &c. are supplied with oscillator heating current of a frequency more than double the frequency of the signals for which the receiver is designed. As shown in Fig. 2, the heating- current is generated by a valve oscillator 42, which has its grid coil 52 coupled to a tuned plate circuit comprising a coil 45, small variable condenser 46 and blocking condenser 51. The filaments of the radio set 11 are connected in parallel across leads 14, 47 in the tuned plate circuit, and each filament circuit includes a blocking condenser 49. The valve oscillator 42 is supplied from A.C. mains 17 through a transformer 18 with three divided secondary coils 19, 20, 21. The coil 19 supplies the filament of the valve 42, and the coil 21 the filaments of rectifiers 24, whilst plate voltage is supplied by the coil 20 through the rectifiers 24 and smoothing circuit 28 - - 30. The grid of the oscillator valve 42 is biassed partly by the condenser 43 and leak resistance 44, and partly by the resistance 38 through which the direct plate current flows. Any modulation of the plate supply due to the A.C. mains is thus balanced out by a modulation in the grid bias. The filament end of the resistance 38 is connected by condensers 40, 41 to the positive and negative leads. The inductance 45 and condenser 46 of the tuned circuit are so chosen that the effective resistance of the loop with all the filaments in circuit is equal to that of the valve 42. When the load is diminished by reducing the number of active filaments, the power output automatically adjusts itself to the reduced load. Similar automatic regulation is also obtained if the supply voltage falls off. Instead of using a single variable condenser 46 for tuning the plate circuit of the oscillator, separate tuning-condensers may be provided in the filament leads with the object of minimizing feed-back effects between the successive stages, due to a common source of heating- current. The system is described (Fig. 1. not shown) applied to a six-valve receiver. Plate voltages for the amplifiers are supplied by a connection to a potentiometer across the condenser 30, whilst the detector plate voltage is supplied through a further series resistance with condenser shunts. Grid bias is supplied to the amplifiers by connecting their grid circuits to the llegaiive end of a resistance traversed by the direct plate currents., The output valve of the set has its filament energized by the transformer secondary 19. Its plate circuit is fed through a choke coil by connection to the positive lead from the rectifier, and the loud-speaker is connected in series with a, condenser between the plate and the mid-point of the coil 19.

Title: Improvements in or relating to corset garments and the like
IPC: A41C1/02
Filed: 1935-09-17
Abstract: 463,047. Wearing apparel. RAVEN, R. F., and RAYNOR, H. A. Sept. 17, 1935, No. 25754. [Class 141] [Also in Group VIII] In an integrally knitted garment or fabric therefo: incorporating elastic o: rubber threads and capable of stretch in two directions the inherent elasticity o: stiffness of two integral elastic areas, that include the same courses and have the same elastic threads extending through them differs. The front pane A of a corset is knitted of À1 x 1 rib. but in the side panels B, certain cylinder or dial needles are omitted, so that at predetermined wales, two consecutive wales of a like kind occur, e.g. to produce a repeating sequence of five wales of 1 x 1 rib, followed by two plain wales : finally, in knitting the back panel C, further needles are omitted, e.g. so as to produce a 2 x 1 rib. In a modification, Figs. 2 and 4 (not shown), the corset has a comparatively close rib front panel of, say, 1 x 1 rib. whilst the back and sides are made of slacker fabric, e.g. by omitting alternate dial needles to produce 2 x 1 rib. The fabric is made on a multifeeder machine having an inelastic thread fed in at all feeders, or at selected feeders, the remaining feeder or feeders supplying an elastic stitch forming thread alone or together with an inelastic thread. A laid-in elastic thread is also fed in adjacent one or more feeders. The fabric may be of tuck-rib (say cardigan or halfcardigan) or of the type described in Specification 428,220, [Group VIII]. Patterning may be effected, as by varying the rib structure, the frequency of courses embodying tuck stitches, the frequency of laying in of elastic threads, and /or the courses of stitches produced from elastic thread. Wrapped or covered elastic thread is preferably employed. The back panel C is longer and stretches more easily than the more closely knitted side panels B, which are, in turn, longer than the front panel A.

Title: Densitometer

Filed: 1971-04-19
Abstract: 1327709 Optical densitometer CIBA-GEIGY AG 19 April 1971 [2 April 1970] 26129/71 Heading G4H [Also in Division G1] An optical densitometer comprises a rotatable grey wedge disc 4, a rotatable chopper disc 5, a source 1 of measuring, 2, and reference, 3, light beams, a photocell 13 receiving alternately, due to the action of the chopper disc, the measuring beam which passes through the sample 11 being measured and the reference beam, a comparator responsive to successive output signals from the photocell and operative when equality is detected to inhibit pulses from an oscillator from passing to a counter, the pulses being initially enabled when the grey wedge passes a datum position, and a means for varying the ratio of the rotational speed of the grey wedge disc and the oscillator frequency. General.-The reference beam is passed through an attenuator 30 which is adjusted so that the intensity of the reference and measuring beams at the photocell are equal when the latter passes through the moxt dense part of the wedge disc. The intensity of the measuring beam consists of a component due to the sample 11 and a component due to the wedge. When the signals due to the two beams are equal the density of the sample is equal to the known signal of the reference beam less the density of that part of the wedge currently intercepting the measuring beam. The number of pulses accumulated in the counter is thus proportional to the density of the sample. The grey wedge disc may function as the oscillator by utilizing a photocell 10. If the chopper and wedge discs rotate at the same speed then the system is equivalent to a wedge having n/2 discrete density portions where n is the number of distinct portions on the chopper disc. By increasing the speed of rotation of the chopper disc the resolution is improved by a combination of an increased frequency of counting pulses and a larger number of effective wedge portions. The chopper may be driven at a constant speed, the resulting counting pulses being passed via a variable frequency multiplier. Alternatively an independent pulse generator and associated frequency mixer may be provided. Further details.-The signals from the photocell are passed to a respective one of two inputs to the comparator under the control of the output of photocell 10. A variable delay is used to delay the start pulse from photocell 9 to compensate for systematic errors. In a modification several samples may be measured simultaneously using a corresponding number of pairs of light beams and a single grey wedge disc and a single chopper disc.
