Title: Improvements in or relating to a device for manipulating windows
IPC: E05F11/38
Filed: 1954-03-29
Abstract: 739,761. Window operating devices. REGIE NATIONALE DES USINES RENAULT. March 29, 1954 [April 3, 1953; Feb. 18, 1954], No. 9130/54. Class 30 (3). A device for manipulating, e.g. a balanced vertically sliding side door window 1 of a vehicle, includes an operating knob 12 slidably mounted on a pin 5 secured by nuts 7, 8 to a plate 4 depending from the lower edge 2 of a frame for the window 1 and extending through a multi-button-hole slot 30 formed in the inner wall 11 of the door and in a reinforcement plate 10, a spring 14, housed within a cylindrical bore 31 in the knob, urging the end portion 16 of the knob 12 into selective engagement with one of the circular openings 17a, 17b, &c. in the slot 30. The spring 14 is restricted between a washer 13 seated on the base of the bore 31 and a knob 15 screwed on to the end of the pin 5, a spring 20 being mounted on the pin 5 adjacent the nut 8 to bear against the plate 10 or, when the latter is omitted, directly against the wall 11. The window is manipulated by pulling the knob 12 until its end 16 is disengaged and then moving it along the slot to the new position, the knob 12 then being released to relock its end 16. In a modification, Fig. 6, the knob 12 is fast with a rod 5, vertically movable in a slot 29 in the inner wall of the door, and displaceable axially in a collar 21 carried by the plate 4, a disc 22 on the free end of the rod 5 forming a shoulder for a spring 23 fitted over the rod 5 and bearing with its other end on the metal plate 4. A pin 24, on the rod 5, engages in a guide slot 25 in the collar 21. Seatings for the part-spherical base of the knob 12 are formed at the upper and lower ends of the slot to lock the window in these extreme positions, alternatively a multi-button-hole slot may be incorporated.

IPC: H02J3/42
Filed: 1929-03-21
Abstract: 330,974. English Electric Co., Ltd., and Wilson, J. C. March 21, 1929. Synchronizing dynamoelectric machines. - The change in the starting connections of a motor-converter required, for example as in Specification 297,343, as the machine approaches synchronism is effected by the aid of a circuit resonant at a predetermined slip ring frequency. This circuit may comprise a choking coil 1 and condenser 2, in series or in parallel, and a relay. The choking coil may be the exciting winding of the relay or the relay winding may be in shunt to the choking coil. The relay closes a circuit causing the switching operation. The tuned circuit may be across two slip rings, or in series with a starting resistance. The Provisional Specification also refers to an arrangement in which the tuned circuit is in shunt to a portion of the starting resistance, and one in which the relay is in shunt to the condenser. In order to avoid a change in the reactance in the tuned circuit by the movement of the relay armature 3 the pole faces and/or armature are so shaped that their adjacent surfaces shall be of very small area as shown at 6.

Abstract: 1421038 Electric testing TOKYO SHIBAURA ELECTRIC CO Ltd 27 Feb 1973 [29 Feb 1972] 9468/73 Heading G1U [Also in Divisions G3 and G4]  Output levels of a circuit having memory function are fixed by gating off the supply of input signals to the circuit when the output levels have the desired values as determined by a circuit including an inverter and changeover switch. The circuit may have an n-bit parallel input (via the gating means), and a similar output which is supplied in true and inverse form to switches which select the true or inverse value of each bit to feed a logic gate which can close the gating means as the desired levels appear at the output of the circuit. Alternatively, the circuit may be a binary counter with a single incrementing input. Each output of the counter may also be connected to earth via a respective voltmeter and to a respective adjustable power source via a respective ammeter and switch. All these switches are closed when the desired counter outputs are reached. In another modification, the apparatus seeks different sets of counter outputs in turn, each set, as it appears, being decoded to perform control functions such as start and stop of a motor driving a conveyer, and starting of first and second measurements on an integrated circuit carried by the conveyer.

Abstract: Di-sodium 2 : 1-hydroxynaphthoate is prepared by reacting sodium beta-naphtholate with carbon dioxide between 98 DEG  and 210 DEG  C. in the presence of at least one equivalent quantity of metallic sodium; the product is substantially free from material containing free hydroxyl groups.  The reaction is preferably carried out in a chemically indifferent liquid such as tetrahydronaphthalene or diphenyl ether.  In the examples: (1) b -naphthol is heated with sodium in the presence of tetrahydronaphthalene to give a solution of sodium b -naphtholate; this is reacted with carbon dioxide in the presence of excess sodium; (2) b -naphthol is heated with solid caustic soda in the presence of tetrahydronaphthalene, the water being removed azeotropically; sodium is then added and carbon dioxide passed in.  The pressure may be atmospheric or higher, and the sodium may be used in the form of amalgam.  The product may be isolated by distillation, filtration or centrifugation of the solvent used, or alternatively the suspension may be used directly for further reactions.  At higher temperatures, a small amount of the 2 : 3-isomer may be formed.  Specifications 6134/85, 8155/86, 9612/89, [all in Class 2], and 647,997 are referred to.

Abstract: 269,190. Akt.-Ges. Brown, Boveri. et Cie. April 12, 1926, [Convention date]. Stuffing-boxes, substitutes for; draining.-In a liquid seal for the shaft of a turbine or rotary compressor, in which sealing liquid is supplied by a pump 10 to a space 4 and is drained by pipes 7, 8 from inner and outer spaces 3, 5, leakage of sealing liquid into the chamber 1 to be packed is prevented by maintaining a flow of the pressure fluid from the chamber 1 to the space 3.
