Title: Improvements in teat cups for milking machines
IPC: A01J5/06
Filed: 1938-09-09
Abstract: 505,956. Cow - milkers. ORRE, B. V. Sept. 9, 1938, No. 26390. Convention date, Sept. 13, 1937. [Class 84] A teat, cup for milking machines to take one or a pair of teats 7 comprises two stiffened side walls 20 adapted to jam the teat or teats between them and connected by two elastic end walls 21 which are so formed that on exerting pressure thereon by the fingers the side walls are caused to be withdrawn from each other against the action of vacuum inside the cup to permit the insertion of the teat or teats 7. As shown, the upper portion 2 of the cup is of rubber or other resilient material having a cover 3 with one or two openings for the teats surrounded by collars 4. The side walls 20 have metal plates 5 for stiffening, the elastic end walls 21 being semicylindrical. The lower portion 1 of the cup is of rigid material and the tip of the teat extends into it to avoid being compressed. In modified forms, one side wall may be stiffened and movable, the other side wall being rigid and immovable as by rigid connection or formation integrally with the lower portion 1, or the teat cup may be made in a single piece, the lower portion being thicker than the upper or having a surrounding stiffening to give the required rigidity.

Title: A control system for an electrostatic line printer
IPC: B41J2/385
Filed: 1966-06-14
Abstract: 1,129,856. Selective signalling. BORGWARNER CORP. 14 June, 1966 [19 July, 1965], No. 26446/66. Heading G4H. In an electrostatic line printer of the type in which an ion-beam-shaping character-apertured belt 17, Figs. 1 and 2, is moved across a dielectric printing web 10, energization of the printing electrodes 16 is controlled by a circuit which, for each character to be printed, computes which character on the belt should be in the first character printing position and energizes the appropriate printing electrode when the character belt has reached this position. The computation is effected, Fig. 5, by adding to each input character the number of its serial position in the input train and storing the result in a corresponding position of a semi-conductor store. A " mask code signal " indicating which character on the belt is in the first printing position, and obtained by counting timing pulses 32, Fig. 2, photoelectrically sensed from the belt, is then compared with all of the stored numbers and the corresponding printing electrodes are energized whenever agreement is attained. In a modification to reduce the possibility of the ion beam partially passing through an adjacent character, the characters on the belt are double-spaced and separated by dots (Fig. 6, not shown), printing of a dot indicating a malfunctioning of the control circuit. Pure or cyclic binary codes can be used.

Patent GB-482746-A (GB)
Title: Improved cellulosic or non-cellulosic fabrics or yarns and the production thereof
IPC: D06M15/423
Filed: 1936-10-01
Abstract: Yarns or fabrics are rendered crease-resisting by impregnating the mercerized material with an aqueous solution of thio-urea, or a substitution product thereof, and acetaldehyde, and drying rapidly at a temperature not exceeding 110 DEG  C.; the thio-urea acetaldehyde solution is prepared at room temperature and is employed at a concentration insufficient to cause stiffening of the material when dry.  Impregnation is preferably effected under pressure by means of rollers.  In an example, a linen fabric is mercerized and dried, and impregnated with an aqueous solution containing 10 per cent thio-urea and 7,5 per cent acetaldehyde by running through rollers, the material is dried at 108-110 DEG  C., lightly soaped to remove excess reagents, and dried.

Title: Improvements in or relating to electric telegraph or remote control systems
Inventor: SPEAKMAN WILLIAM GERALD
IPC: G08B9/00
Filed: 1957-08-23
Abstract: 881,563. Electric correspondence control systems. CHADBURNS (LIVERPOOL) Ltd. Nov. 18, 1958 [Aug. 23, 1957], No. 26620/57. Class 40 (1). In an electric system for transmitting angular rotation, a motor at the receiver controls a follow-up switch at the transmitter, via a selsyn link, to cut off its power supply when it has performed the correct angular rotation. At the transmitter end, movement of handle 10 in the clockwise direction rotates two arcuate control segments 12, 13 relative to interconnected brushes 16a, 16b, whereby the brushes connect segment 12 to the positive terminal of the supply via a centre ring 11, producing energization of relay R1, followed by contactor C1, thereby causing energization of the armature of receiver motor 21, which rotates in the appropriate direction. At the receiver end there is a second transmitter comprising a stator consisting of two main contact segments 25, 26 connected to the positive and negative terminals of the supply and separated by a number of small segments interconnected, except for the central segments, by resistors or inductors 27. Lying on the surface of the stator are three equi-spaced brushes 22, 23, 24 driven by the motor 21, the brushes being connected to a 3-phase stator winding 20 at the transmitter end, whose rotor carries the brushes 16a, 16b and a pointer 19. Thus the movement of handle 10 causes rotation of motor 21 which is followed by brushes 22, 23, 24 and brushes 16a, 16b until brush 16a is located over the gap 14 between segments 12, 13. This breaks the circuit for R1 from segment 12 to centre ring 11, but R1 remains energized via interconnected auxiliary brushes 30, 31 at the receiver end, which connect an inner ring 28, leading to the positive terminal of the supply, to an outer ring comprising a series of interconnected segments 29. Thus motor 21 continues to run until brush 30 is located over the insulation between two segments 29, enabling the motor to be aligned to within half a degree. Angular movement at the receiver is limited to 180 degrees in either direction by segments 32, 33 which, via brush 30, energize relay R3 or R4 to release the previously energized contactor C1 or C2 and cause the motor 21 to stop. Specification 777,573 is referred to.

Title: Improvements in weighting animal fibres
IPC: D06M13/256
Filed: 1932-05-21
Abstract: Animal fibres are weighted by treatment with an aqueous acid bath containing at least 10 per cent. by weight calculated on the fibres of alkylsulphuric esters having at least eight carbon atoms in the molecule or soluble salts thereof.  The weighting may be effected together with other textile processes e.g. dyeing.  By using halogenated alkyl sulphuric esters (obtainable according to Specification 394,043) increased weighting is obtained.  In examples: (1) woollen piece goods are treated at the boiling point with an aqueous bath containing the sodium salt of oleyl sulphuric ester and sulphuric acid: (2) wool yarn is similarly weighted with a bath containing sulphuric acid and dodecyl sulphuric ester: (3) woollen hose is weighted and dyed in a bath containing the sodium salt of octodecylsulphuric ester, sulphuric acid, Fast light yellow 2G, Amidonaphthol red G and Cyanthrol BGA: (4) wool yarn is first weighted with tetradecylsulphuric ester and then dyed in the same bath with Patent blue V: (5) felt hats are first dyed with Biebrich patent black 4AN and then weighted in the same bath by the addition of formic acid and the sodium salt of cetyl sulphuric ester: (6) woollen fabric is weighted in a bath of the sodium salt of trichloroctodecylsulphuric ester.  Besides wool and silk, rabbits', hares', dogs', camels' and cows' hair and other animal fibres may be weighted.  Brominated sulphuric esters are mentioned.
