Title: Improvements in means for automatically operating entrance gates
IPC: E05F13/04
Filed: 1958-05-05
Abstract: 829,171. Gate operating appliances; remotely controlled fastenings. BRADY, D. May 5, 1958 [July 3, 1957], No. 14243/58. Classes 44 and 65(1) A gate operating appliance comprises a lever 4 pivoted near the ground 3, having a short arm 5 incorporating a laterally extending tread 6, and a long, inclined, weighted arm 7 coupled by a cable 12 to the gate 1, so that the gate is opened on downward movement of the arm, a latch 10 for holding the arm in its raised position being operated to release the arm when a vehicle passes over a contact pad 50 or a pressure pad 20. The arm 7 is restored to its original position by depression of the tread 6. The latch plate 10 is mounted by means of a slot 34 on a pivot pin 35 carried by a post 11 and is loaded by a spring 36. It is held in the position shown by a catch 31 and, in the open position of the gate, by an arm 38 on the gate. The gate is held in the open position by a catch 40. The catches 31, 40 are tripped at the appropriate times by pins 30, 42 respectively on a ratchet wheel 29 operated by a cable 23, when the pressure pad is depressed. If a contact pad is employed the ratchet mechanism is operated by a solenoid energized by the car battery, by means of contacts suspended beneath the car and adapted to engage contact pins of the pad.

Abstract: 1,099,477. Extruding strapping. T. J. KARASS. April 5, 1965 [July 2, 1964], No. 14250/65. Heading B5A. [Also in Division E2] High tensile strength strapping is made by melt extruding polymeric material through a uniformly heated substantially rectangular die orifice, uniformly cooling the extrudate, heating the extrudate to a temperature below its softening point while at the same time applying a stretching force to axially orientate the molecules, and finally heating the extrudate while in. a relaxed condition a temperature above the second order transition temperature but below its softening point to anneal the material of the strapping. Polymeric materials specifically mentioned are polyethylene, polycarbonates, polyesters, nylons, acrylic resins and polystyrene, with polypropylene being the preferred material. Such material may be rendered light stable by the addition of suitable pigments. The strapping is intended to be of generally rectangular cross section, but may be somewhat thicker in the middle or at the edges, the edges may be rounded and ribs or grooves may be provided to act as registering devices when the strapping is wound into coils. Fastenings.-A fastening C, Figs. 3 and 4 (not shown), comprises metal bent to form a sleeve, the free edges of which are spot or line welded and the strapping A is held by crimps 18, 19 and dimples 21. A releasable fastening made from wire is coupled to the strapping as shown, Figs. 6, 7 (not reproduced), the or a free end of the strapping being first looped around transverse bar 112. A second releasable fastening, Figs. 8, 9 (not shown), is stamped from sheet steel.

The compounds are prepared by acylating 6-aminopenicillanic acid, or a salt thereof, with an acylating derivative of an acid of formula <FORM:1124920/C2/2> 3-methyl-4-furazanacetic acid is prepared by (a) treating 3-methyl-4-furazancarbonyl chloride with diazomethane to form the diazoketone, (b) treating the diazoketone with benzyl alcohol and N,N1-dimethylaniline to form the benzyl ester of 3-methyl-4-furazanacetic acid, and (c) hydrolysing the benzyl ester with mineral acid.  The starting material for (a) is produced by treating 3-methyl-4-furazancarboxylic acid with thionylchloride.  The penicillins are effective against gram-positive and gram-negative bacteria and may be administered orally to man and animals, e.g. for the treatment of mastitis in cattle or as a nutritional supplement in animal feeds.  The penicillins may be formulated into pharmaceutical compositions.

Patent GB-144024-A (GB)
Abstract: 144,024. Watson, E. A., and M.-L. Magneto Syndicate. April 9, 1919. Magneto - electric machines. -A magneto, having a shuttle armature a, Figs. 2, 3, and 4, and a two-part commutator e for giving unidirectional current impulses, is combined with a switch m which is arranged to deliver some of the current impulses into an induction coil o' for the ignition of an internalcombustion engine, the remainder being delivered into a storage battery l. The magneto is self-regulating the current output of the machine being limited at high speeds by suitably proportioning the lengths of the commutator segments f, f<1>, or the inductance of the armature winding b, or by arranging an inductance in series with the armature winding. One end of the armature winding is connected to a commutator segment f by means of a pin g and metal strip h; the other end of the winding is earthed, and connexion is made with the other segment f<1> when a sufficient speed is reached, by a centrifugal cut-out consisting of a contact on a blade spring i and a cooperating contact screw j on the segment f<1>. The switch m has the form of a spring blade actuated by a cam r to engage one or other of the fixed contacts n, n<1> and connect the commutator brush k either with the battery l or with the primary winding o of the induction coil. Both ends of the armature winding may be insulated and connected directly to the commutator segments, the cut-out in this case being separate from the magneto. In the arrangement shown in Fig. 7, the ignition coil o is placed in series with the armature winding b and may serve as an inductance to limit the generated current; the winding b is adapted to be periodically short-circuited by the switch m. The coil o, in a modified system, may also be periodically short-circuited by the switch m or by a segmental switch rotating with the cam r.

Title: Process for preparing unsaturated polyester resins curable in air
Inventor: BEHAR ROBERT
IPC: C08G63/52
Filed: 1959-05-01
Abstract: Unsaturated polyester resins which harden in the presence of air are prepared by heating a mixture of at least one olefinically unsaturated polycarboxylic acid or anhydride and at least one polyhydric alsohol in the presence of a polyether containing at least two beta-gamma-unsaturated alkenoxy groups but no esterifiable groups and which copolymerises with the polyester formed.  Preferred features are that the acid and alcohol should be reacted in stoichiometric proportions; the polyether should be present in an amount of 10 to 45 wt. per cent. of the acid plus alcohol; and the reaction should take place in the presence of an organic solvent which removes the water of esterification azeotropically.  Acids mentioned are maleic, fumaric and itaconic which may be mixed with phthalic or adipic acid.  Polyhydric alcohols mentioned are ethylene, diethylene, and propylene glycols and the butane diols.  Suitable polyethers have the general formula: <FORM:0947701/C3/1> where R, R1, and R2 are H or alkyl; n is 1, 2 or 3; R1 is a residue of an alkane polyhydric alcohol R1(OH)n+ 1 and m is 0, 1, 2, 3 or 4. The polyesters are used conventionally in solution in an olefinically unsaturated comonomer, e.g. a vinyl, allyl or methallyl ester, styrene or vinyl toluene.  Copolymerization may be effected with an organic peroxide catalyst with or without a metal salt, e.g. cobalt napthenate or octoate, or tertiary amine accelerator.  In examples hydroquinone is used as an inhibitor and titanium dioxide as pigment. Ethylacetate and/or dibutyl phthalate are used as dispersants for the pigment and catalyst.
