Title: Dampproofing of buildings and other constructional elements
IPC: E04G23/02
Filed: 1976-01-26
Abstract: 1526023 Damproofing J H GROBLER 26 Jan 1976 02915/76 Heading DIP A sealing element 44 of an apparatus is expanded to seal a hole 74 of a constructional element 76 in order that a pressure fluid, which causes the element 44 to expand, can be fed into the sealed hole 74 through a pipe 40 of the apparatus for impregnating the constructional element. The apparatus includes a piston sleeve 42 slidable within a cylinder 54 and a pipe 48 which is in communication with the pipe 40 through a passage which is normally blocked by a sealing member 68. Pressure fluid enters the chamber of the cylinder 54 via an aperture 72 in the pipe 48 and causes the sleeve 42 to slide to expand the element 44. When fluid pressure exceeds the force of the member 68 fluid enters the hole 74 of the constructional element via the pipe 40. Pressurised fluid may be allowed to enter the interior space of the element 44 through an aperture (78) in the pipe 40 to expand the element 44 Figure 3 (not shown). The piston sleeve (106) may be integral with the cylinder (108) to be movable together Fig. 4 (not shown). In another embodiment the piston sleeve (210) is moved by passing pressure fluid into the chamber of the cylinder (208) through a hole (216) in the cylinder (208) Figure 5 (not shown).

Title: Remote control system
IPC: H03J1/18
Filed: 1946-02-01
Abstract: 606,622. Electric follow-up systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 1, 1946, No. 3269. Convention date, Feb. 26, 1945. [Class 40 (i)] In a remote-control system, potentials from the controlling and controlled devices are applied to the electrodes of a pair of multielectrode discharge valves to cause dissimilar functioning thereof except when the potentials are the same and, in the former case, to cause a change in the setting of the controlled device. In one embodiment the ends of a controlling potentiometer 1, Fig. 1, and a motor-driven controlled potentiometer 4 are connected across a source of potential 11 and their moving contacts 2, 5 are connected through opposed rectifiers 20, 24. As long as there is no potential difference between the two arms 2, 5, the grid of each discharge tube 21, 25 is at the same potential as the corresponding cathode. Both tubes pass current and energize relays 29, 32, and the supply circuits to the motor field windings 9, 10 are thus opened. If the arm 2 is moved away from this equilibrium position the resulting difference in potential appears almost entirely across the oppositely poled rectifier 20 or 24, causing the corresponding tube grid to go negative with respect to its cathode and cutting off the valve. The associated anode relay 29, 32 releases and a circuit is completed through the appropriate motor field winding 9, 10 to cause the motor to run in a direction such as to reduce the potential difference between the two arms 2, 5, until, when this is zero, both valves are again conducting. By modification of the circuits it can be arranged that the tubes are cut off when the pointer settings are the same and pass current only when a change in position of the controlled arm is necessary. In the alternative arrangement shown in Fig. 2, each potentiometer arm 42, 50 is connected directly to the grid of one tube and cathode of the other. In this case, if one arm becomes negative with respect to the other, the grid connected to it also becomes negative with respect to its associated cathode. The tube is thereby cut off and the corresponding anode relay 58, 59 releases to set up the appropriate circuits for the motor 46.

Title: Improvements in electronic switching circuits
IPC: H03K17/64
Filed: 1959-01-30
Abstract: 883,715. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 30, 1959 [Jan. 30, 1958], No. 3358/59. Class 40 (9). [Also in Group XL (c)] Fig. 1 shows a circuit for indicating the state of the data stored in a magnetic core storage device 3 by virtue of a relay circuit which has main and auxiliary windings with positive feed-back between them connected to a PNP junction transistor in a blocking oscillatortype circuit. If it is assumed that initially magnetic core 3 has a stored " 1 " and thus is at the top point of its rectangular hysteresis loop then a read pulse applied to winding 4 switches the core to its lower branch and a negative pulse is applied to the. base of the transistor 2 from winding 5 of core 3. This pulse overcomes the positive blocking bias at the base and the transistor 2 is switched to the conductive state which change is augmented by the positive feed-back between the main and auxiliary winding of the relay 1. Relay contact 8 is opened removing earth from the negative collector battery which is applied to the base and maintains the transistor conductive. The operation of contact 8 may also be used to emit a signal representing the storage condition of core 3. By selection of the feed-back winding of the relay of the value of resistor 6 and the number of turns on winding 5 the core just read-out through winding 4 immediately restores to " 1 " state. If the auxiliary winding of the relay is bridged by diode 10 thus providing a low-resistive path to ground which by-passes the auxiliary winding for signal pulses induced in winding 5 of core 3 a lowsignal voltage may be used. The modification shown in Fig. 2 similarly operates with low signal amplitude for initiating the switching process, since by diode 12 feed-back current is kept away from winding 5 of core 3. If, as shown, resistor 9 is not used and positive battery to earth is provided in the line leading to contact 8 current flows through diode 12 in the forward direction so that the gate voltage determines the blocking voltage of the base emitter path of transistor 2. The circuits of Figs. 1 and 2 may be restored to their inoperative condition by momentarily opening switch 7. The relay 1 may be of the magnetostrictive type.

Abstract: 295,406. Fritzsche, J. Feb. 7, 1927. Drawings to Specification. Utilizing waste rubber.-Consists in using, in the manufacture of blasting or like fuzes, as a covering for the core of the fuze a material consisting of or containing or made wholly or in part from rubber vulcanized before application to the fuze, for example scrap rubber obtained from old tyres &c., treated by heating and kneading or rolling, with or without the addition of other ingredients. Such added materials may consist for instance of resins, waxes, pitch, hydrocarbons, bitumen or oils. Filling materials such as kaolin, chalk or talc, and fibrous substances such as cotton, wool, or asbestos may be used. Proportions of ingredients and working temperatures are specified in the description of the preparation of examples of the compositions. Preferably, the composition used contains a certain proportion of unaltered vulcanized rubber. The material may be applied to the fuzes in liquid or in plastic form, and several successive coatings may be applied, with intermediate windings of yarn if desired.

(1) Citric, tartaric, or acetic acid is substituted for the neutral salts of copper. lead, mercury or silver. When employing nitric and tartaric acids, the vegetables are dusted with the powdered acid prior to the crushing; in the case of acetic acid, the addition is made to the vegetable juices. The acids are removed before the extraction treatment. (2) The use in the Soxhlet apparatus of glycerine as the solvent. The material to be extracted is placed in the lower vessel 14 and the whole apparatus is filled with glycerine; owing to the difference in temperature between the bath 19 and the cooling coil 18, the glycerine circulates in the apparatus and ultimately deposits the C vitamine on a filter paper in the vessel 11. The Specification as open to inspection under Sect. 91 (3) (a) describes also the extraction of the A vitamine from both the expressed juices of vegetable and from the solid residue after expression. The juices are treated with the organic acids, and the solvents employed for the extraction are benzene, petroleum ether, ethyl ether, acetic ether, acetone and chloroform. To obtain the A vitamine from the vegetable residue, the latter is desiccated in vacuo in the presence of sulphuric acid and then extracted with the solvents. This subject-matter does not appear in the Specification as accepted.
