Title: Improvements in and relating to electric motor control systems
IPC: H02P3/10
Filed: 1940-01-01
Abstract: 537,739. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 1, 1940, No. 56. Convention date, Dec. 30, 1938. [Class 38 (iii)] Traction motors have a dynamic braking circuit prepared during coasting. Upon return of the accelerating controller to " off switch LB1 and LB2 open and switch B closes, thus completing a braking loop through resistances 19, 21 and energization of the field 16, 17 from a battery 53. The voltage across part of the resistance 21 is applied to coil 44 of a relay 46 and thus controls coil 47 operating the fluid valve of device 27 which adjusts resistance 19 so as to obtain a low current in the braking loop. When the current in the loop reaches a predetermined value, the relay 46 engages its upper contact and causes field shunting contactors FS3 and FS4 to close. The motors continue to coast with fields partly excited and a small current in the braking loop. Operation of a braking controller then causes contactors FS3 and FS4 to open and give full field for dynamic braking. Specifications 514,005 and 514,263 are referred to.

Abstract: Uredjaj sa konstantnom depresijom za odstranjivanje prašine iz grubih prečistača vazduha, prema pronalasku, je konstruisan tako da ukupan protok gasova kroz motor se, na izlazu iz motora a pri ulasku u ovaj uredjaj, deli na dva dela. Jedan deo gasova ide kroz cev (6) a drugi kroz cev (7). U cevi (6) se nalazi mlaznica (8) koja služi da stvori depresiju za odstranjivanje prašine iz grubih prečistača vazduha. U mlaznici (8) je postavljena cev za odstranjivanje prašine (9) koja je preko odgovarajućeg creva povezana sa komorom grubog prečistača vazduha iz koje depresija, stvorena na račun povećanja brzine gasova u mlaznici (8), izvlači u prečistaču već izdvojenu prašinu. U cevi (7) se nalazi leptir (10) koji je preko zavrtnjeva (12) pričvršćen za osovinu (11) na kojoj se nalazi poluga (13) sa priključkom (15) za komandu promene radnog režima motora. Cevi (6) i (7) su na oba kraja zavrtnjevima (4) kroz otvore (5) spojene spojnim pločama (3) sa ulaznim i izlaznim priključcima (1) i (2). Komanda promene radnog režima motora se povezuje sa polugom (13) preko priključka (15) tako da pri delovanju komandi za promenu radnog režima motora u smeru povećaja protoka vazduha kroz motor dolazi do otvaranja leptira (10) da bi protok gasova kroz cev (6) i mlaznicu (8) ostao konstantan i nezavistan od režima rada motora, a uvećani deo protoka biva usmeren kroz cev (7). Tako se ostvaruje konstantna depresija u mlaznici (8) i optimalno odstranjivanje prašine iz grubih prečistača na svim radnim režimima. Opruga (14) pomaže zatvaranje leptira pri smanjenju protoka gasova kroz motor.

Abstract: A base plate for use in packaging of foodstuffs, mainly sides of salmon, fillets and whole salmon, in which the food is placed on the base plate and then vacuum-packed in a plastic film, which base plate consists of two pieces of glued-together cardboard laminated with a plastic film on the front and back.  The pieces of cardboard consist of at least two layers, in which the layer of the pieces turned towards one another is not quite so waterproof as the other layers, and in which the glue used to glue the two pieces of cardboard together is an aqueous glue which penetrates into the not quite so waterproof layer and following setting makes these two layers stiff and waterproof.  It results in a particularly stiff product using a very inexpensive glue without harmful additives. The laminated-on plastic film can be applied to the lacquer in reverse, alternatively the glue with which the plastic film is laminated on can be coloured. The foodstuff does not then come into contact with the lacquer, but exclusively with the plastic film.

Abstract: A rigid sheet comprises a polymeric constituent formed from monomers in which vinyl chloride predominates and reinforcing fibres, the polymeric constituent being rigid at room temperature when not reinforced, and the fibres being uniformly dispersed throughout and all lying in or substantially in the plane of the sheet. In one embodiment the polymeric constituent comprises a dispersion or emulsion of polyvinyl chloride in water together with a solution of a vinyl chloride copolymer in an organic solvent e.g. a vinyl chloride/vinylidene chloride copolymer dissolved in toluene or a vinyl chloride/vinyl acetate copolymer dissolved in methyl ethyl Ketone and, optionally, a hydrocarbon fraction.  Alternatively, the polymeric constituent comprises a mixture of the said copolymers, one being dispersed in a solution of the other e.g. the vinyl acetate copolymer is dispersed in a toluene solution of the vinylidene chloride copolymer.  Asbestos and/or glass or organic fibres are added.  In the first example toluene solutions of a vinyl chloride/vinylidene chloride copolymer and of a styrene/diester of maleic acid and a C8 alcohol copolymer are mixed with additional toluene, powdered polyvinyl chloride, an aqueous polyvinyl chloride latex, stabilizers, talc, asbestos and pigment. This mixture is used to form the base layer of a laminated sheet and a similar mixture, without the styrene copolymer and containing a greater proportion of polyvinyl chloride, is used to form the body layer.  The aqueous phase of both mixtures may contain a minor amount of another latex e.g. a butadiene/acrylonitrile copolymer latex.  In the second example the body layer comprises a toluene solution of a vinyl chloride/vinylidene chloride copolymer, a vinyl chloride/vinyl acetate copolymer, asbestos stabilizers, talc and water.
