Abstract: 922,756. Fibrous fabrics. CARL FREUDENBERG KOMM. GES. AUF AKTIEN. July 21, 1959 [Aug. 1, 1958], No. 25005/59. Class 42 (2). [Also in Group XV] A paper-like sheet material which disintegrates in water without agitation is made from a loose fibre fleece by impregnating it with a water-soluble film-forming substance, drying it to adhere the fibres together, rewetting it and smoothing by calendering. The fleece consists of cardable natural or synthetic fibres or mixtures of both, e.g. cotton, linen, hemp, ramie, wool, cellulose acetate staple, polyvinyl alcohol fibres, nylon, " Perlon " (Registered Trade Mark) or " Trevira " (Registered Trade Mark). The filmforming substance is one adapted to adhere to the fibres and form a film-like coating on them and so act as a binder, examples are methylcellulose, cellulose glycolates, polyacrylic acids, water-soluble polyacrylates, polyvinylpyrrolidone, polyoarboxylic acids, water-soluble ureaformaldehyde condensation products, dextrins, sugars, alkali, ammonium and triethanolamine alginates, corragheen moss solutions, alkali caseinates and waterglass. Fillers, emollients or hygroscopic substances and dyes may be added to the film-forming substance. The impregnation may be carried out by placing the fleece between two wire screens and immersing the screens and fleece in an aqueous mixture of film-forming substance and other ingredients. After the impregnation, the upper screen is removed, and the wet fleece dried on the lower screen.

Abstract: 853,024. Substation equipment. SOUTHERN INSTRUMENTS Ltd. Nov. 15, 1957 [Aug. 15, 1956], No. 25022/56. Drawings to Specification. Class 40 (4). A phonographic device for answering and recording incoming calls comprises a first recording and reproducing means for transmitting pre-recorded messages at the beginning and the end of an incoming call, a second recording and reproducing means for recording a message from the calling party, and control means responsive to the cessation of incoming speech impulses for rendering the second recording and reproducing means inoperative, starting the first recording and reproducing means to transmit the pre-recorded closing-down message, and disconnecting the device from the line at the end of this message. The recording and reproducing means comprise two magnetic tapes driven by a common motor by means of an electromagnetically - operable clutch. The control means consists of a valve timing circuit, which is reset to zero by an incoming speech impulse, and, after a predetermined break in such impulses, operates a relay to effect the necessary circuit changes. If, while an incoming message is being recorded, the recording tape becomes exhausted, the closing-down message is sent and the device is disconnected from the line. If less than a predetermined amount of tape is left when an incoming call is received, the device does not answer. Low-level incoming signals, such as cross-talk, are not recorded.

Title: Improvements in apparatus for recovering, or separating, caustic hydroxides from solutions containing them and for analogous purposes
IPC: C01D1/38
Filed: 1924-10-23
Abstract: 237,468. Johnson, J. Y., (Viscosc Co.). Oct. 23, 1924. Waste products, treatment and utitization of. -Apparatus for the recovery of caustic alkali from " black liquor " from pulp mills comprises a series of compartments a containing a series of dialytic cells 20 through which the waste liquor is passed in the opposite direction to a flow of a solvent such as water through the series of compartments. As shown, a pipe 18 conveys the water from the bottom of one compartment to the upper part of the next, the inlet and outlet pipes being preferably at opposite ends of each compartment. A pipe 21 conducts impure solution from an open extension 22 above each cell, to the bottom of the next cell. The open extensions 22 are stated to compensate for the varying density of the solution. Each cell comprises an open frame having flanges to which the edges of the membranes are secured by frame-plates. Vertical bars also bolted to the flanges may provide feet and handles at their opposite ends. Sediment may be removed from the cells by suction pipes let down through the extension 22. Suitable membranes may be prepared by immersing cotton sheeting in sulphuric acid of sp. gr. 1.1 at a temperature below 30‹ C. for two minutes and removing the acid.

Title: Improvements in apparatus sensitive to changes in direction
IPC: G01C19/56
Filed: 1945-09-28
Abstract: 610,530. Electric indicating systems. SPERRY GYROSCOPE CO., Inc. Sept. 28, 1945, No. 25313. Convention date, Sept. 30, 1944. [Class 40 (i)] [Also in Groups XX and XL (c)] Relates to instruments in which direction or rate of turning is measured by the consequent changes in the motion of a vibrating wire as described in Specification 601,051. The wire 1 is stretched in the air gap of a permanent magnet (not shown) and is fed with a driving current, the frequency of which is controlled by the wire itself so that vibration takes place at the resonant or natural frequency of the wire (see Group XL (c)). Direction and rate of turning is determined from the variations in magnitude and phase of currents induced in the wire 1 by coils 7 fed with alternating current at any desired signal frequency. As shown, the thermionic oscillator 29 supplies, through the low impedance bridge 1, 13, 14, a driving current in the wire 1 at the resonant (fundamental) frequency and, through the amplifier 40, a signal current to the coils 7 at the third harmonic. The induced voltage in the wire 1 will be of second harmonic frequency and, after amplification at 30, is introduced at 35 into a phase-sensitive circuit including triodes 32, 33, to the grid circuits of which is supplied a reference voltage of second harmonic frequency, derived from the mixing circuit 31. The rate of turn is indicated in magnitude and direction at the meter 36,

Title: Apparatus for exercising a joint of a human or animal to improve blood and lymph circlation therein and therearound
IPC: A61H9/00
Filed: 1964-06-19
Abstract: 1,060,578. Treatment chambers. N. A. MACLEOD. June 19, 1964 [June 21, 1963], No. 25398/64. Heading ASR. A chamber for applying fluid pressure to a limb to exercise a joint comprises means 13, 29, 30 for supporting a limb or part of a limb in direct contact with a fluid in the chamber and means for alternately applying pressure to the fluid and releasing said pressure so that the limb is alternately stretched and relaxed. A chamber 10 is open at one end for receiving a leg, a seal 13 being provided at the open end to surround the thigh. The seal has an inner periphery which engages the thigh and which is connected to a source of reduced pressure to render it fluid-tight when the leg is in the chamber. The leg is supported by hard rubber cushions 24, 25, 26 and the foot is secured by straps 29, 30. The chamber receives a liquid through a fitting 35, a fitting 36 permitting the escape of air during the fitting process. The pressure of the liquid is cyclically increased and decreased as a piston 44 is reciprocated, the piston being resiliently connected to a compressed air-driven reciprocating piston 50 which is controlled by a slide valve 56. Increase in pressure applied to the liquid causes the thigh to move outwardly of the chamber thus extending the knee joint. The chamber may also be open at the other end and have a seal extending around the ankle so that the foot lies outside the chamber. The apparatus may be modified to enclose the whole or part of a hand or arm, a seal being provided around the wrist or shoulder, and the finger tips or wrist being resiliently secured within the chamber, so that the application of pressure variations to the liquid in the chamber causes stretching of the joints of the fingers or the elbow. The chamber may be filled with gas, the pressure of which is cyclically varied.
