Title: A cabinet for storing and exposing a length of textile or like material
IPC: A47K10/28
Filed: 1923-01-19
Abstract: 207,723. Garrey, M. M. Jan. 19, 1923. Reel and non-endless web apparatus. -A length of textile or like material b, stored in a cabinet A and having portions in the form of a freely suspended loop successively exposed, is wound from a storage roller 3 to a receiving roller 7, passing on its way over feed rollers 4, 5 having rubber or other gripping surfaces. The material travels through a cross-slot a<3> in a hinged door a<1>, over a suspension roller 2, under a spring- pressed rod 16 and between a roughened feed roller 6 and the roller 7. To prevent the material being pulled off the roller 7, the rod 16 is mounted on a lever 14 carrying a projection 15 which engages with the gear teeth on the roller 6 when the rod 16 is raised by a pull on the material b, and further, a suspended spring- pressed plate 18 has a serrated edge which grips the material when this is moved in the wrong direction. Movement of the material b off the roller 3 is restrained by a spring 8, and the roller 7 is journaled in spring-supported pivoted arms 11 guided by arcuate bridge-pieces 11<b>. The rollers 5, 6 are geared together so that the same length of material is wound on the roller 7 as leaves the roller 3. The roller gears 5<b>, 9, 9<a>, 6<a> may be contained in a casing 10 to protect the material b from oil. The apparatus is particularly suitable for holding towelling for use in hotels, &c. The cabinet A may be equipped with a mirror or other toilet requisites.

Title: Improvements in light controlled apparatus
IPC: H01H47/24
Filed: 1934-01-17
Abstract: 423,395. Electrically-actuated valves. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATENFABRIEKEN, 30, Croeselaan, Utrecht, Holland. Jan. 17, 1934, No. 1734. Convention date, Jan. 17, 1933. [Class 135] [See also Groups XL, XXXV, and XXXVII] A control arrangement for lights comprises a sensitive light receiver A which produces electric current to operate a change-over relay B, the armature C of which after completing a portion of its controlling movement, comes under the influence of a magnet D, E. This provides an additional force which assists the switching control and after completion of the movement forces for preparing for the reverse action of the relay are brought into operation. In position 1 which occurs when very little illumination is received at A, the armature engages the lever F to open a valve H, whereupon gas flows into the space J and to the burner K where it is ignited by a pilot flame. The pressure of the gas in the chamber J depresses the diaphragm L against the spring M, and operates a rod pivoted at H to engage a cam P and move the armature G out of the range of the additional force. When darkness disappears or the light receiver A energizes the change-over relay in the opposite direction, the valve H is closed, and the diaphragm L collapses and by engagement of the rod with the cam O removes the armature from the range of the magnet E. In a modification (not shown), the movement of the diaphragm L rotates lever arms which move the magnets away from the armature of the change-over relay. In another modification, Fig. 5, the position of the diaphragm determines the energization of the magnets D, E, by operating switch contacts O, P, so that, after operation of the relay on one side, the switch contacts are closed to energize the coil of the electromagnet on the opposite side to prepare for the reverse action.

Title: Analog memory system
Inventor: SMITH LAWRENCE RAY
IPC: G11C27/02
Filed: 1969-01-13
Abstract: 1,245,661. Analogue stores. MOTOROLA Inc. 13 Jan., 1969 [1 Feb., 1968], No. 1843/69. Heading G4G. [Also in Divisions H1 and H3] An analogue memory system including a charge storing capacitor 19, Fig. 3, is provided with a guard plane 60 in the vicinity of the capacitor and at a potential equal to that produced by the charge stored on the capacitor whereby leakage from the capacitor is reduced. A charge to be stored is applied to capacitor 19, Fig. 2, through serially connected MOSFETS 40, 41 when opened by a gating pulse on their gate electrodes. The capacitor voltage is read by a differential amplifier 73 through a MOSFET coupling circuit 22. The output circuit 82 of the differential amplifier provides outputs to low and high impedance outputs 16, 17 and a feedback output which supplies the potential to the guard plane 60. Leakage through the input and output circuits is reduced by leaving the MOSFET substrates floating and by connecting the feedback potential to the junction of MOSFETS 40 and 41 to increase the apparent impedance thereof when non-conducting. The substrates of the MOSFETS 71, 72 are thermally coupled to prevent temperature-sensitive asymmetry. In the event of power failure, capacitor 19 will retain its charge for a considerable period, but it may be desirable to charge the capacitor 19 to a safe potential by connecting it through a resistor 108 to a reference potential 107.

Abstract: 1,029,852. Resistance thermometers. CIBA Ltd. Jan. 16, 1963 [Jan. 16, 1962], No. 2053/63. Heading H1K. A resistance thermometer consists of a tem perature sensitive resistance element (e.g. a platinum coil) surrounded by insulating material and assembled in a protective sleeve with a layer of material of high thermal conductivity between the sleeve and tube. The sleeve is pressed into contact with the element by a method which leaves indentations in its outer surface. In a typical arrangement, Fig. 2, the protective sleeve 14 is of a stainless steel containing chromium, nickel and molybdenum. Foils of aluminium, copper or silver are pressed around the glass tube 10 by rolling the outer surface of the sleeve to provide it with circular or helical grooves. Alternatively, or in addition, the sleeve may be grooved longitudinally by rolling and additional grooves may be milled in its surface. The grooving, by locally reducing the wall thickness of the sleeve and improving the thermal contact between sleeve and tube reduces the response time of the thermometer.
