Title: Improvements in devices for automatically hooking fish
IPC: A01K93/02
Filed: 1921-08-15
Abstract: 188,094. Pennell, J. G. Aug. 15, 1921. Automatic striking-apparatus.- A wire loop 3, normally held in the position shown by springs 4, can be turned about the spindle 2 so that an eyed projection 7 thereon passes through a hole 12 in the casing 1. A pivoted plate 11 is then turned up over the loop and is held by a corrugation 10 on a hinged catch 8. When thus set, the hook line 16 passes through the eye 7, forward through a hole 13 in the casing and is attached to the free end 9 of the catch 8. When a fish bites, the catch 8 is raised, and the loop 3 flies up to its normal position, shortening the line by a length AB. Oppositely-pitched vanes may be formed on the sides of the casing to rotate it when trolling.

Title: Frequency divider circuit
IPC: H03K25/00
Filed: 1946-07-19
Abstract: 614,680. Frequency dividing circuits. FARNSWORTH TELEVISION & RADIO CORPORATION. July 19, 1946, No. 21686. Convention date, Oct. 17, 1945. [Class 40 (vi)] In a frequency dividing circuit pulses from a generator 11 are applied through a diode 21 to a capacitor 4, charging it in one or more steps until gas-filled tube 1 fires, causing capacitor 4 to share its charge with capacitor 5 in the ratio of their capacities, which is the factor by which the stage divides. Similar action occur for tubes 2 and 3 and capacitor 5 and 6 when all the capacitors discharge through load resistor 7 producing an output pulse. The first stage is preferably arranged so that tube 1 fires for each pulse. In a modification a sine wave input to be divided is applied through a transformer between the anode of diode 21 and earth (Fig. 2, not shown).

Abstract: 214,537. Maclure, G. M. Aug. 31, 1923. No Patent granted (Sealing fee not paid). Channels in tappets.-Lubricant is supplied to a conduit 15 'in a tappet rod 3 of an internalcombustion engine for lubricating the joint between the rod 3 and a rocking arm 2 operating a valve stem 1, from a recess 11 in the tappet guide 13 which registers with transverse apertures 12 in the tappet 4. The ball end 8 of the rod engages a socket formed in a plunger 9 in a bore in the tappet, the plunger having a reduced lower portion 10. A slight clearance is left between the reduced portion 10 and the bottom of the bore in the tappet, so that lubricant supplied under pressure to the recess 11 passes through the apertures 12 and under the plunger to the conduit 15 when the tappet is in its lowest position. The plunger may be dispensed with, in which case the apertures 12 communicate directly with the conduit 15. The lubricant serves also to lubricate the tappet guide and the connection between the tappet and the tappet rod.

Title: Manufacture of arsenobenzenes
IPC: C07F9/74
Filed: 1927-08-26
Abstract: 300,716. Albert, A. Aug. 26,1927. Arsenobenzenesare prepared by the reduction of an aromatic arsenic compound, or a mixture of two different aromatic arsenic compounds, in an acid medium using as reducing agent a mixture of hypophosphorous acid or a salt thereof with sulphurous acid or one of its salts. The proportions of hypophosphorous acid may be widely varied without affecting the nature of the product. but in the case of the sulphurous acid there should not be present more than one-third of a molecular proportion for each molecular proportion of the arsenic compound. If, however, one molecular proportion or more is used for each molecular proportion of the arsenic compound, arsenobenzenes are obtained which contain sulphur. Hydriodic acid or a salt thereof mav also be present. The products, which are crystalline, are useful therapeutically. Examples are given of the reduction of (1) the semicarbazone of 3 - aldehyde - 1 - phenoxyacetic acid-6-arsinic acid, (2) a mixture of the semicarhazones of 3-hydroxy-1-benzaldehyde-4-arsinic acid and of 3-aldehydo-1- phenoxyacetic acid-6- arsinic acid, (3) the semicarbazone of 1-benzaldehyde-3-hydroxy-4-arsinic acid, using various proportions of the reducing mixture, (4) the semicarbazone of 1-acetophenone-3-hydroxy-4-arsenoxide, (5) 3-aminobenzene-4-hydroxy-1-arsinic acid, using sufficient sulphurous acid to produce a sulphur-containing product. Specification 259,245 is referred to. The semicarbazone of 3-aldehydo-1-phenoxyacetic acid-6-arsinic acid is obtained by the action of chloracetic acid on the semicarbazone of 3- hydroxy-1-benzaldehyde-4-arsinic acid, whose preparation is described in Specification 259,245.

Abstract: 406,927. Rubber tubes. DALMAU, F. CAPELLA-, 34, Calle Pelayo, Barcelona, Spain. Aug. 15, 1933, No. 22827. Convention date, April 28. [Class 99 (ii).] Rubber tubes with designs on their outer surface are made by inserting an embossed mandrel into a soft rubber tube, partially vulcanizing the tube by means of a fluid under pressure which presses the tube on to the mandrel, then turning the tube inside out by means of a fluid under pressure within a rigid tube, and completing the vulcanization. As shown, a rubber tube 1 is fitted over a mandrel 2 to each end of which is screwed an air chamber 3. One end of the tube is secured by vulcanized rubber ring 5. When the whole apparatus is subjected to steam pressure in a boiler, the rubber tube is forced on to the mandrel, the air between the tube and the mandrel escaping through passages 6 into 3. When the tube is partly vulcanized, chambers 3 are removed, and the mandrel is placed in a container over one end of which the tube is turned back. Compressed air or other fluid entering at 10 in the direction of the arrows turns the tube inside out. A pipe 11 is placed so as to prevent ballooning of the tube. Reference is made to the production of tubes more than 30 feet long. The tubes may be of 8 mm. internal diameter or of large diameter.
