Title: Manufacture of vulcanised rubber articles
Inventor: FISHBEIN JOHN
IPC: C08J5/02
Filed: 1952-04-19
Abstract: Vulcanized synthetic rubber products, especially foam sponge rubber, are obtained by compounding an aqueous dispersion of butadienestyrene copolymer with an organic thio-compound and an oxidizing agent, shaping the dispersion, permitting the dispersion to gel solely by the reaction of the thio-compound with the oxidizing agent, and then vulcanizing the gel.  The thio-compound, which is added in an amount up to 5 per cent by weight, may be thiourea, a mono- or di-alkyl thiourea such as methyl thiourea, a mono- or di-aryl thiourea such as orthotolyl thiourea, or a dithiocarbamate such as a sodium or zinc salt of dithiocarbamic acid or of dimethyl- or diethyl-dithiocarbamic acid.  The oxidizing agent may be hydrogen peroxide, ammonium or alkali metal persulphate or sodium percarbonate.  Reaction may be effected at temperatures up to 70 DEG  C.  Sulphur, zinc oxide, mercaptobenzthiazole or a castor oil soap may also be added.ALSO:Rubber products, especially of sponge rubber, are obtained by compounding a vulcanizable aqueous rubber dispersion with an organic thio compound and an oxidizing agent, shaping the dispersion, permitting the dispersion to gel solely by the reaction of this compound with the oxidizing agent, and then vulcanizing the gel.

Title: Insulated electrical conductor
IPC: H01B7/295
Filed: 1934-03-29
Abstract: 418,351. Conductors. ROCKBESTOS PRODUCTS CORPORATION, 285, Nicoll Street, New Haven, Connecticut, U.S.A.- (Assignees of Reeves, B. H. ; 285, Nicoll Street, New Haven, Connecticut, U.S.A.) March 29, 1934, No. 9889. Convention date, April 6, 1933. Drawings to Specification. [Class 36.] Insulation for a conductor consists of asbestos impregnated with an alkaline silicate, particularly sodium silicate, the object being to produce a coating which vitrifies on the occurrence of a short circuit without producing harmful gases. The insulation preferably is applied in the form of untwisted rovings reinforced by a central thread of asbestos yarn. Between the insulation thus constituted and the conductor is a layer of asbestos impregnated with borax or boric acid. The insulation may consist of several layers impregnated with solutions, the strength of which progressively decreases from within outwards, the total dry weight of sodium silicate being preferably about 15 per cent of that of the asbestos.

IPC: F16H15/46
Filed: 1982-01-06
Abstract: PURPOSE:To keep an idler in its neutral posture until it is displaced from its neutral position into contact with a driving rotary member, by providing a member which is located in contact with the idler at its two diametrally symmetric points when the idler is located between both driven rotary members. CONSTITUTION:Two protrusion 18a on the tip of a friction rod 18 are brought into contact with an idler 17 by a kick spring 20. Although an idler base 15 can be swung right and left about a control pin 14, the idler base is kept in the neutral state because a rightward and a leftward equal forces are applied to the center shaft of the idler 17 by the two protrusions 18a of the friction rod 18. When the idler base 15 is moved toward a driving roller 1, the idler 17 is continuously pushed by the protrusions 18a of the friction rod 18 so that the idler on the idler base is kept in the neutral state until the idler is displaced into contact with the driving roller 1.

IPC: G06F11/30
Filed: 1989-01-09
Abstract: PURPOSE:To repeatedly impress a reset signal to a microprocessor by outputting a pulse at definite cycle only during the generation of an alarm by a timer circuit, and generating the reset signal by differentiating it. CONSTITUTION:The timer circuit 9 to output the pulse at definite cycle during the generation of an alarm is provided. When the microprocessor 1 runs away on account of some cause, and a watch dog pulse comes not to be outputted, a watch dog break supervision circuit 2 executes alarm detection, and makes a flip flop 4 hold an alarm signal 5. On the other hand, the timer circuit 9 receives an alarm detection signal, and inputs the pulse of the definite cycle to a differentiation circuit 3 during an alarm detecting period. Therefore, this differentiation circuit 3 generates the reset signal (reset pulse) continuously by the pulse of the definite cycle, and resets repeatedly the microprocessor 1.

Abstract: PROBLEM TO BE SOLVED: To easily remove a spacer film formed beforehand and increase the degrees of freedom in designing by forming an aerial interconnection which has supports formed on a first and a second terminal formed on a semiconductor substrate and has through-holes in areas other than those where supports are formed. SOLUTION: This semiconductor device is constituted such that elements 2a, 2b, 2c are formed on a semiconductor substrate 2 and a first terminal (the terminal of the element 2a) and a second terminal (the terminal of the element 2b) respectively are connected by an aerial interconnection 5. In the aerial interconnection 5, a plurality of through-holes 12 are formed in areas other than those where supports 5a, 5b are formed. Due to this structure, a spacer film preliminarily formed under the aerial interconnection 5 can be removed easily via the through-holes 12. Since a plurality of through-holes 12 are formed, the dead weight of the aerial interconnection 5 is lighter than that of the conventional, thereby preventing it from being brought into contact with other elements, signal lines and the like due to its bending.  Furthermore, there is no need for forming many supports an the reduction in the degrees of freedom in designing can be prevented.
