Abstract: 740,504. Reinforced rubber &c. tubes. RESILLA COTS & ROLLERS, Ltd. Aug. 18, 1954 [Sept. 4, 1953], No. 24550/53. Class 99(2). In a method of making a drafting apron for a textile machine, a tube composed of rubber or rubber-like polymer covered by a tubularly woven fabric is mounted on a mandrel and is surrounded by a layer of rubber or rubber-like polymer. The inner and outer layers of rubber may comprise butadiene acrylic nitrile copolymer, olefin polysulphide, polymerised chloroprene, plasticized polyvinyl chloride or copolymers of polyvinyl chloride and acetate, and the woven fabric tube may comprise weft threads of nylon or other artificial fibrous material, or " Terylene " (Registered Trade Mark). An extruded tube of rubber may be inserted in the fabric tube and expanded into' contact with the latter by compressed air, this composite tube then being mounted on a mandrel; alternatively, a fabric tube is drawn over a sheet of rubber wrapped around a mandrel and joined at its edges. In order to hold the composite tube securely the ends of the tube are drawn tight and tied beyond that part of the mandrel which is of the desired diameter and thereafter the outer layer of rubber is applied by extrusion ; alternatively, the outer. layer comprises a wrapping of sheet rubber joined at the edges thereof, or an extruded rubber tube is drawn over the composite tube with the aid of compressed air or a solvent acting as a lubricant. The completed tube is wrapped with tape and vulcanised while on the mandrel and by the use of steam, and is preferably buried in a tray of french chalk or other pulverulent substance which supports and prevents sagging of the tube or flats from being formed. The outer surface of the completed apron may be ground and treated with chlorine, iodine or bromine water to improve the performance of the apron in fibre handling and drafting. U.S.A.

IPC: B65B7/04
Filed: 1925-10-05
Abstract: 262,551. Berkshire Printing Co., Ltd., Brooke, N., and Ballard, R. Oct. 5, 1925. Paper and like bags, folding down months of after filling. - To effect the closing of the open ends of tea and like packets, one side b, Fig. 18, of the mouth of the packet a is first folded down so that two sides present inclined edges c, which are creased to define the edges. The side portions are then turned inwards about lines d, perpendicular to the edges c, so as to form a top flap e, Fig. 19, of rectangular form covering the end of the packet. When the apparatus is used in combination with a machine such as is described in Specfication 262,550, each filled packet is dropped into a packet holder g, Fig. 1, with a slidiable bottom h, the open end being indicated at i. A pair of fingers j, on co-axial spindles k, L, Fig. 3, enter the mouth and expand the sides and form a support during the first folding operation. A folder 16 advances, and at the same time turns from an inclined position approximately into a horizontal position to form the preliminary fold b, Fig. 18, with a wiping action. The fingers j withdraw and creasers 22 descend and define the creases c. The creasers each comprise a pair of flexible metal plates spaced apart for a portion of their periphery and in resilient contact for the remainder. Horizontal folders 23, Fig. 1, next move inwards so as to produce the folds shown in Fig. 19, a presser plate 31 flattening the top. The sides g of the holder are opened out and the bottom h is withdrawn to allow the packet to face clear or with another portion of the machine. The requisite motions of the folders, creasers, and holders are produced by the action of stationary cams 4, 7, 30, 37, 38, 42 upon racks or slides carried by the rotating heads of the machine. Each holder is associated with similar folding and creasing mechanism. The Provisional Specification states also that the sequence of operation may be varied so as to produce a triangular top flap.

Abstract: 1,090,524. Transistor pulse and sawtooth circuits; pulse modulation circuits. GENERAL PRECISION Inc. June 3, 1966 [Sept. 14, 1965], No. 24971/66. Headings H3T and H4L. [Also in Division G4] An unknown analogue voltage signal is applied to a Miller integrator 11, 12 (Fig. 3) the output from which e 0  is a steadily decreasing or steadily increasing negative voltage depending on whether the input signal was positive or negative, the rate of change of the voltage e 0  being proportional to the amplitude of the input signal. The voltage e 0  is applied to a generator 16 the output voltage from which, having the same slope as the input e 0 , is applied to a delay multivibrator 17 which delivers a negative pulse e 2  to a gate 18 whenever the voltage e 1  reaches - 3 volts. The polarity of the slope of the voltage e 1  is indicated by a positive voltage on one of the leads 22, 23 so that when an output pulse e 2  appears from delay multivibrator 17 both the transistors of one of the pairs 66, 67 or 68, 69 are cut off to give a positive output pulse on one of the leads 24, 25. The output pulses together with the voltages on leads 22, 23 are applied to a ramp generator (Fig. 4) which via a switch 27 (Fig. 2) resets the Miller integrator during each output pulse on leads 24, 25. The frequency of output pulses at 24 or 25 is proportional to the magnitude of input to integrator 11, 12; positive and negative inputs respectively causing output pulses on leads 24 and 25.

Title: Improvements in or relating to momentum power-storing apparatus for use in connection with steam power plant
IPC: F01K3/00
Filed: 1922-09-15
Abstract: 186,332. Kõgi, E. Sept. 21, 1921, [Convention date]. Momentum power-storing apparatus. - In steam power plant of the type in which the exhaust steam is used for heating &c. purposes while the engine itself performs mechanical work, the engine supplying exhaust steam is provided with a fly-wheel rotating at a variable speed and designed to absorb the engine power in excess of that required for the power shaft when there is a large demand for exhaust steam so that this power may be added to the power developed by the engine when there is a smaller demand for exhaust steam and more demand for mechanical power. Fig. 1 shows the engine a coupled up to a mechanical power shaft d and to a fly-wheel e through variable belt gearing. When the demand for power falls or the power developed by the engine rises, the whole system is accelerated at first. A governor i thereupon moves the belt g so that the fly-wheel is further accelerated and stores up momentum which it gives up to the system when the demand for power rises. In another arrangement, the fly-wheel e is - interposed between the engine and the power shaft. If desired, the engine may be coupled with a fixed transmission ratio to the fly-wheel and a continuous current generator, the voltage of the latter being maintained constant by means of an automatic voltage regulator of known type.

Title: Improvements in and relating to radio receiving systems
IPC: H03G11/02
Filed: 1920-08-31
Abstract: 172,376. Taggart, J. Scott-, and Radio Communication Co., Ltd. Aug. 31, 1920. Thermionic amplifiers; atmospherics, limiting. -In a method of limiting the effect of loud signals, currents due to the signals are passed through a thermionic valve so as to set up back electromotive forces to lessen the effects in the receiver, or the receiving circuit is shunted by a rectifier conductive to currents of above a predetermined amplitude. The method is applicable to limiting both audio- and radio-frequency currents. In one example a three electrode valve with a telephone in its plate circuit has the received signals applied to its grid. Shunted across grid and filament is a two-electrode valve in series with a battery adapted to give its anode a negative potential. When signal currents are strong enough to make the anode positive, some of the current is by-passed through the valve. In another example, Fig. 3, a resistance R is connected as shown in the grid circuit of the receiving valve V<2>. When a strong positive half-cycle from the receiving circuit L<2>, C<1> is making the grid of the valve V<2> positive, current through the valve V' sets up an electromotive force across the resistance R tending to make the grid negative. In either arrangement two oppositely-connected two-electrode valves may be used to obtain bypassing for both half-cycles. According to the Provisional Specification three-electrode valves may be used in place of two-electrode valves, and continuous waves may be received with an ordinary detector if the damping is made periodic.
