Title: Digital electronic timepiece
IPC: G04G15/00
Filed: 1975-12-08
Abstract: 1493640 Electronic timepieces DAINI SEIKOSHA K K 8 Dec 1975 [20 Dec 1974] 50225/75 Heading G3T An electronic timepiece has an electro-optical display (L.E.D. or L.C.D.), on a section B of which time of day in hours and minutes and in addition the day and seconds are displayed (although only four digits are shown), while on a section B2 an item of time information stored in a memory 9, such as railway timetable items, is displayable. An alarm means may be operated when the times displayed on B1 and B2 coincide, and B2 may then be switched to display the next item stored. The memory 9 stores items of timetable for a whole day. An address counter circuit 11 sequentially reads items stored and feeds items read signals via a buffer circuit 10 to be de-coded at 12 and applied to a driver 13. The latter drives the section B2 to indicate hours and minutes of the respective item read. A coincidence circuit 14 produces a clock signal when the hours and minutes indications in B1 and B2 coincide. The clock signal may also be produced by the opening and closing of a manually operable switch 15. This signal is applied via an OR gate to the address counter circuit 11 which causes the next item of information stored to be displayed on B2. The timekeeping circuit A, as shown, is conventional and includes a crystal controlled oscillator circuit. One memory circuit may be exchanged for another, depending upon the stored information required or means (not shown) may be provided to rewrite the contents of the memory.

Title: Amplifiers
IPC: H03F3/30
Filed: 1975-12-08
Abstract: 1508450 Transistor amplifiers WESTERN ELECTRIC CO Inc 8 Dec 1975 [9 Dec 1974] 50290/75 Heading H3T A linear amplifier, e.g. for a submarine cable repeater, comprises a pair of transistors 1, 2 connected in push-pull, means for biasing the transistors at or near saturation, and means 34 or 34a for supplying constant collector currents for at least short durations. The effect of an applied A.C. signal is to saturate alternately one transistor of the pair, rendering it equivalent to a short-circuit, Fig. 3 (not shown), and the arrangement is called "Class B-dual" or "Class AB-dual" according to whether the biasing is at or near saturation. The constant current supplies are for handling large amplitude, short duration signals, e.g. frequency division multiplex signals, with a relatively low voltage collector supply. An input signal at 11 is coupled to a transformer 12 connected to a matching network 14 terminated by a resistor 15. Base bias for the transistors 1, 2 is provided by the network 17, 18, 19 co-operating with inductors 20. Negative feedback is provided by 27, 28. D.C. emitter bias and common mode stability are provided by a network 29. A resistor 30 is the collector load, coupled to output 32 via a matching network 31. Allowing the transistors to saturate causes base charge storage which delays recovery from saturation, and is a cause of non-linearity. This effect is obviated by diodes 21 poled in the same direction as the collector-base junctions and biased so as to turn on at or just before transistor saturation. Schottky barrier diodes, or alternatively PIN diodes may be used for diodes 21.

Abstract: 1457252 Crop storage RANSOMES SIMS & JEFFERIES LTD 21 June 1976 50585/72 Heading A1F [Also in Division B8] A blade 10 for distributing crop in a storage tank 1 is adapted for reciprocal movement along a shaft 6 parallel with the side of the tank to which the shaft is attached. The shaft 6 is mounted between arms 5 fixed to a rod 3 which is rotatably mounted in bearings 4 rigidly fixed to the tank wall. Abutments 12 on the tank wall restrict the rotation of the blade 10, about rod 3, to those elevations above about 20‹ below horizontal. A double acting hydraulic cylinder 7 is mounted on the shaft 6 and is caused to reciprocate along shaft 6 by alternating the fluid supply between its ends. The cylinder 7 carries a bracket 8 having a fixed abutment 11 and a shaft 9, perpendicular to shaft 6, about which blade 10 may rotate in a sense, confined by abutment 11, between a position perpendicular to shaft 6 to a position parallel to shaft 6, the blade is spring loaded towards the former position by a spring 13. As the tank fills up the blade 10 rests on the surface of the crop and its elevation decreases with further increase in crop level.

Title: Printable polyethylene film
IPC: C08L23/06
Filed: 1963-12-24
Abstract: A composition suitable for making films comprises a normally solid polyethylene, 10-50% by weight thereof especially 10-40% of an ethylene-vinyl acetate copolymer and optionally 0.1-15% by weight especially 0.5-5.0% of said polyethylene of a free radical generating agent, suitably dicumyl peroxide, 2,5-dimethyl-2,5 - (t - butyl peroxy) - hexane, 2,5 - dimethyl-2,5 - (t - butylperoxy) - 3 - hexyne, t-butyl perbenzoate, 2 - phenylazo - 2,4 - dimethyl valeronitrile, 2-phenylazoiso butyronitrile, 2-phenylazo - 2,4,4 - trimethyl valeronitrile and 2-phenyl-azo-isobutyramide. The term "polyethylene" is defined as including homopolymers of ethylene and copolymers of ethylene with a minor amount of another a -mono-olefin. Pigments, dyes, fillers and stabilizers may also be added.  Mixing may be effected by dissolving the cross-linking agent in a solvent, e.g. petroleum ether, inert to the polyethylene and copolymer, mixing said solution with the copolymer in resin, pellet or granule form and heating to a temperature sufficient to evaporate the solvent but not so high as to decompose the cross-linking agent.  Hence the product comprises polyethylene and copolymer pellets or granules having a uniformly distributed surface coating of cross-linking agent. Alternatively, the particulate polyethylene resin and copolymer and liquid or powdered cross-linking agent are dry-blended until the cross-linking agent is homogeneously distributed throughout the mass, or the mixture may be fluxed on a two-roll mill or Bambary mixer at temperatures below the gel point of the admixture.  Where a cross-linking agent is used, the mixture is extruded in the form of a film or tube which is then heated to effect cross-linking.  Where no cross-linking agent is used, the mixture is extruded in the form of a film or tube and irradiated to effect cross-linking.  U.S.A. Specifications 2,612,480, 2,628,208 and 2,866,231 are referred to.

Title: Means for connecting conveyor sections
IPC: B65G19/28
Filed: 1966-11-16
Abstract: 1,131,863. Conveyers. GEBR. EICKHOFF MASCHINENFABRIK u. EISENGIESSEREI m.b.H. 16 Nov., 1966 [19 Nov., 1965], No. 51255/66. Heading B8A. Means for connecting sections 1 of channel shape of a face conveyer comprises a pair of superposed lugs 3, 3<SP>1</SP> fixed to the sides and near the ends of the conveyer sections 1 and a fishplate 4 placed between these lugs. The fishplate 4 is held to one of the sections 1 by a longitudinally split resilient hollow spring pin 5 extending through the lugs 3, 3<SP>1</SP>. The ends 6, 6<SP>1</SP> of each fish-plate 4 are wider than the vertical distance between the lugs 3, 3<SP>1</SP> and act to limit the range of horizontal swivelling movement between the sections 1, 1. The fish-plate 4 has a tapered cross-section to facilitate the desired relative movement both in the horizontal and in the vertical planes. Stressing of the pin 5 is prevented by the widened end 6 of the fishplate 4 resting on the side faces of adjacent lugs 3, 3<SP>1</SP> while a nose 7 on the fish-plate bears on the side wall of the conveyer to prevent pivoting about the pin 5. The trapezoidally shaped overlap 8 of one bottom of a section 1 on the bottom 9 of the adjacent section 1, tapers towards its end and is formed and dimensioned so that it also limits the relative horizontal swivelling movement of the sections 1. The deflected section 1 is accordingly not able to press against the fish-plate 4, see Fig. 3.

Title: Improvements in process of tempering nylon strands
IPC: C08L77/00
Filed: 1963-12-31
Abstract: 1,014,280. Tempering nylon strands. UNITED STATES RUBBER CO. Dec. 31, 1963 [March 18, 1963], No. 51277/63. Addition to 893,386. Heading B5B. A nylon strand is tempered by first cold stretching it until it has attained the constant length at which it is to be held during the subsequent heat treatment to which it is to be subjected and is then heated to a temperature not exceeding 7‹ F. above and not more than 80‹ F. below the melting point of the strand for a period of from 30 seconds to 7 minutes, preferably 3 to 7 minutes, under conditions such that the oxidation of the nylon is substantially prevented either by carrying out the heat treatment in an atmosphere free from air or by the use of polyamide strands containing a small proportion of an anti-oxidant. The melting point of the strand is determined when the strand is free from tension and situated in an atmosphere having the same pressure as the atmosphere in which the tempering process is carried out. The tempering process of the invention may be carried out upon the strands, twisted cords made from the strands or a web of those cords. The term " nylon " is used to describe any polyamide and the strands to be treated may be composed of any nylon material, but the process of the invention is particularly applicable to nylon 66 and nylon 6, the nylon materials most widely used as tyre cords. The tensile force applied to the strand to stretch it to the constant length at which it is to be treated may be sufficient to produce a tension just short of the breaking stress of the strand at the tempering temperature, but the tension is preferably about ¢ to 3 grams per denier. The strand may be heated by heating the rolls over which the strand is passed, by space heaters disposed within the tempering zone, or, when the process is carried out in an atmosphere of superheated steam, by the heat content of this steam. The process is preferably carried out in an atmosphere of superheated steam substantially at atmospheric pressure. Laboratory and field tests for measuring the flat spotting tendencies of tyre cords after these cords have been used in the construction of a pneumatic tyre are described. The process of the invention reduces these tendencies.

The acylation may be performed in two stages with differing acylating agents to give different groups Ac in the 8 and 14 positions. The acylation is carried out preferably in an inert solvent in the presence of a condensing agent such as trifluoracetic acid anhydride. The carboxylic acid, its halide or anhydride may be used as acylating agent. When a mixture of the 8- and 14-monoacyl derivatives are formed, they may be separated chromatographically. Partial hydrolysis of the diacyl derivative may be effected with an aqueous acid or alkali, or by adsorbing the derivative on a suitable adsorbent (e.g. silica gel or alumina) and exposing it to moist air, or by hydrolysis with enzymes of the T-2636C- producing micro-organism Streptomyces rochei var. volubilis. For this procedure the whole culture, a culture filtrate, a crude enzyme preparation or an acetone-powder of the mycelium of the micro-organism are used as the hydrolysing agent. The acyl derivatives of T-2636C have improved antibiotic activity against Grampositive bacteria.
