Filed: 1972-11-16
Abstract: 1375460 Pulse generators FRANKE & HEIDECKE GmbH [trading as ROLLEIWERKE FRANKE & HEIDECKE] 16 Nov 1972 [25 Nov 1971 (2)] 53066/72 Addition to 1314907 Heading H3P [Also in Division G2] The firing of a flash tube 11, energized by the discharge of a capacitor 7, renders a control element, e.g. thyristor 12, conductive via a capacitor/voltage divider resistance network 14, 15, 16. The flash tube continues to discharge until a photo-electric integration measuring device 20 operates a switch 18 when a predetermined exposure has neen reached and discharges a capacitor 17 in the opposite direction to the flash tube current which quenches the thyristor and terminates the flash tube current.

Title: Digital watch
IPC: G04G99/00
Filed: 1974-12-10
Abstract: 1461969 Electronic watches HUGHES AIRCRAFT CO 10 Dec 1974 [10 Dec 1973] 53448/74 Heading G3T In an electronic watch having a digital display device, e.g. of liquid crystal or l.e.d. type, energized via an integrated circuit device, the two devices are arranged on a common base substrate and are interconnected via leads from pads adjacent one edge only of each device. Other connections e.g. to electric cells (54, 56) Fig. 4 (not shown) or to pushbuttons 100, 102, 104 may run from the other edges of the devices. As shown, base substrate 26 carries a display substrate 22 and an I.C. substrate 27 with circuit chips 28, 30. Leads 67 run between pads along adjacent edges of the substrates, or alternatively a plug and socket connector may be used. A transparent window (72) covers the display and an hermetically sealed cover 76 encloses the I.C. substrate. The display and circuit devices may be on opposite sides of the base substrate Figs. 5, 6 (not shown) and the display module 24 may be mounted directly on the base substrate 26 Fig. 7 (not shown). A lamp or l.e.d.106 is energized by push-button 100 to allow a liquid crystal display to be read in the dark. The display then normally shows hours and minutes but button 102 produces a date display and buttons 100 and 102 pressed together produce a seconds display. Button 104 is for setting.

Title: Method and apparatus for handling a yarn drawn at a high speed from a bobbin by a processing machine
IPC: B65H51/20
Filed: 1972-11-21
Abstract: 1404638 Yarn reserve apparatus and method H-STUTZ 21 Nov 1972 [24 Nov 1971 12 April 1972] 53657/72 Heading D1F In a method of handling yarn to form a reserve between a bobbin and a processing machine, an air flow is generated which enters a yarn storage compartment 26 in the direction of the axis of throughpassage of the yarn and at a velocity greater than the average speed of withdrawal of yarn from the compartment by the processing machine, the air flow leaving the compartment 26 at an angle with respect to said axis of throughpassage whereby the air flow delivers the yarn F into the compartment and the excess over that withdrawn is deposited in the compartment in the form of loose, non- entangled loops disposed adjacent one another, the height of the compartment being chosen to be greater than but less than twice the diameter of the yarn processed to ensure non-entangled loops. In a preferred form of apparatus, the compartment 26 is formed in a container 21 by means of a closure disc 22 and segmentshaped spacer elements 23, 24 between the closure disc 22 and the floor 25 of the container. Yarn inlet and outlet tubes 28, 29 are coaxially aligned at diametrically opposite sides of the compartment 26. The floor 25 of the compartment is provided with outlet openings 30 and is provided with a connection 31 for coupling to a source of suction. In use air and yarn F are drawn in through the inlet tube 28 and, because the yarn is not being withdrawn by the processing machine, is deposited in loose loops in the compartment 26; the air flow leaves via openings 30. As more yarn is deposited, the openings 30 become covered and the air flow is thus reduced to reduce the amount of yarn deposited in the container. On operation of the processing machine, yarn is withdrawn from the compartment 26 via outlet tube 29. The openings are uncovered, the air flow increased and more yarn is deposited. A braking action is exterted on the yarn as it passes through outlet tube 29 by the air flow entering via tube 29. In alternative forms of apparatus, the compartment and associated inlet and outlet tubes are aranged as an interchangeable unit in a vacuum chamber. In this case, the air outlet openings may be arranged in the side wall of the compartment and may be radial or be parallel to one another and directed at an angle to the yarn through passage axis. The compartment may be circular or rectangular in cross-section. To assist in the formation of non-tangled loops, a reciprocating fork or bifurcated member may be positioned at the inlet to the chamber. The passing of the yarn over, the outlet openings and the passage of air therethrough performs a self-cleaning function in the compartment.

Abstract: 544,651. Ketals. DU PONT DE NEMOURS & CO., .E. 1., and MOCHEL, W. E. Oct. 18, 1940, No. 15427. [Class 2 (iii)] Ketals are formed by reacting a mercaptol with an alcohol in the presence of an acid interchange catalyst. The mercaptol is prepared for instance by reacting a ketone with a mercaptan. In examples, 2-2 bis-(ethylthio) butane the mercaptol made from methyl-ethyl ketone and ethyl mercaptan, is reacted with methyl alcohol and the mercaptol from methylethyl ketone and cyclohexane thiol is re-acted with methyl alcohol. Suitable catalysts are hydrochloric, p-toluene sulphonic, acids of sulphur, phosphorus and chlorine, boron trifluoride and its complexes, strong organic acids such as aromatic and aliphatic sulphonic acids, and chloracetic acid, acid-acting salts such as tin and aluminium chlorides, and heteropoly acids containing an oxide of phosphorus, silicon, boron or arsenic together with other groups such as oxides of tungsten, vanadium, chromium, molybdenum, tellurium and sulphur. An unsaturated ether such as 2-methoxy-butene-1 may appear as a byproduct, formed by loss of a molecule of alcohol from the ketal. This reaction can be effected by heating the ketal with an acid catalyst, the reaction being reversible.
