Filed: 1974-03-14
Abstract: 1467376 Washing machines PHILIPS GLOEILAMPENFABRIEKEN NV 14 March 1974 [15 March 1973] 11438/74 Heading D1A To prevent unbalance in a washing machine when a spin drying cycle is interrupted and the drum speed falls below a threshold value (e.g. 80 r.p.m.), the drum is refilled with water and then in response to a first high water level sensor switch rotated alternately in opposite directions to distribute the laundry again and then operation of a pump and rotation of the drum in a single sense is initiated, the motor supply being regulated for spin drying in response to a second water level sensor switch 5. In a machine with the circuit shown with a heater 6 in series with the D.C. motor 1 supplied through a rectifying bridge 2 with two thyristors controlled by a regulating device 3, and two water level sensor switches 4, 5 closed in response to a full and an empty tub respectively. After interruption spin drying the tub is filled with water and. the motor supplied through the water level sensor switch 4 and periodically reversed, as in the washing cycle, until the timer starts the spin drying cycle by actuating a pump to reduce the water level and permit drum acceleration. As the switch 4 opens after a delay the timer contact 7 closes to continue the motor supply and the water level sensor switch 5 and timer switch 8 close to permit the regulating device 3 to control the thyristors controlling the motor speed. The device 3 compares the back e.m.f. of the motor with a reference voltage during the periods when the motor is not energised by the rectifying device and should the drum speed drop below 80 rpm stops the motor by turning off the thyristors.

Title: Improvements in and relating to Automatic Train Pipe Couplings.
Inventor: MATHYS ALBERT WILLIAM
IPC: B61G5/06
Filed: 1916-08-14
Abstract: 105,187. Mathys, A. W., (White, W. C.). Aug. 14, 1916. Couplings, disconnectible. - Relates to train-pipe couplings of the kind in which two similar couplerheads carrying the train-pipes, steam-pipes, electric conductors, &c. are automatically coupled when the cars are coupled. Each coupler-head 1, Figs. 7 and 8, has a number of chambers 2, 3, 4 into which the pipes &c. 5, 6, 7 enter, and, in order to guide the heads together, each is constructed with a guide-arm 27 adapted to co-operate with a body portion of the other head and with a body portion comprising an inner inclined vertical face 11 having a number of ports 12, and an outer vertical face consisting of an inclined portion 22, a second portion 23 almost parallel to the axis of the coupling, and an offset portion 24. Fig. 12, having converging ribs 25 for guiding the tapered nose 28 of the guide-arm 27. The inner faces of the guide-arms 27 have portions 29, 31 inclined slightly more than the portions 22, 23 on the body. Wings 32 at the top and bottom of the coupler-heads and adapted to ride upon the arms and bring the heads to the same level. Each head has rearwardlyextending arms 8 with slots 9, through which pass pins on a pipe-carrier 58 slidable vertically on rods 50 connected to the car coupling 49, Fig. 1. The pipes 5, 6, 7 pass loosely through holes in the carrier 58 and are ball-jointed at 58<a> the arrangement allowing the coupler-heads a limited pivotal and sliding movement with respect to the carrier. The coupler-heads are further supported from the car coupling by braces 56 connected to shelves 55, on which the heads are adapted to rest. The necessary telescopic movement of the heads with respect to the pipes and electric conductors is provided for as shown in Fig. 7. The steam-pipe 5 passes into the chamber 4 through a steam-tight packing 34; the air-pipe 6 terminates in a piston 35 in the chamber 3 and is held against rearward movement by an abutment 36 engaging against a plate 37 on the draft-yoke 54, the air pressure in the chamber 3 thus acting to press the coupler-heads together; and the electric conductors pass through telescopic casing 48 and are coiled at 47 in the chamber 2 and connected to terminals 41 arranged in insulating-blocks 42. In addition, portions of the pipes may be arranged to telescope upon each other. The ports 12 in the coupler-heads are elongated and have seatings 14, Fig. 13, to receive the flanges 15 of correspondingly-shaped gaskets 13, which are retained in position by notched keepers 16, Fig. 14, consisting of pairs of plates with oppositely bevelled meeting edges 18.

Title: Improvements in or relating to the water-resistance of shaped articles comprising polyvinyl alcohol
IPC: C08J7/12
Filed: 1944-06-16
Abstract: Shaped articles of polyvinyl alcohol are made water-insensitive by treatment with an aqueous solution of at least 15 per cent of a strong base in the presence of air and at a temperature of from 50-90 DEG  C.  Bases such as sodium hydroxide and quaternary ammonium bases are used, preferably in 30 per cent concentration. Wetting agents such as isopropyl naphthalene sodium sulphonate may be used in the solution.  Films are either wetted with the solution and dried in an atmosphere of nearly 100 per cent humidity or are immersed in the solution and air bubbled in; both processes take from 1-6 hours and are followed by washing free from the base.  The treated films may be used for wrappings and safety valve diaphragms.

[Class 119] An automatic sporting gun has a space above the usual cartridge-transporter into which a single reserve cartridge can be placed by hand when there is already one round in the chamber. With a first round in the barrel 9, Fig. 7, a second round is fed to a space above the transporter 3a and below the breech block 6 by insertion through a side opening 2a, Fig. 3, normally partly closed by a shutter 10 controlled by a spring 10a. The reserve round then rests on the transporter and remains there until the first round is fired when the barrel recoils carrying the breech block with it until the block is held by a catch x on the transporter. The barrel then returns to its normal position and by means of a cam rocks a pivoted stop 7 to release the transporter whilst the breech block is held open by catch x engaging projection y. The transporter pivoted at 3b is also freed from a second pivoted stop 8 engaged by the inserted cartridge and rotates clockwise to move the round into the path of the breech block which is released by the transporter and rams the round into the chamber of the barrel.

The stop bus-bars d are arranged in two sets, one for the Great and its pedal stops and the other for the Swell and its pedal stops. Each set of stop bus-bars is connected to its own volume control comprising a main e and series of resistances f, of which resistances there are a series for each stop and, say, fifteen (three shown) in each series. Drawing a stop closes the contacts g of its series of resistances on fifteen volume-control bus-bars h connected to contacts i cumulatively connected by a foot switch k to the positive terminal of the supply, putting the resistances of each series in turn in parallel until short circuited by a contact i<1>. The resistances f are proportioned according to whether they are under the control of loud or soft stops ; a series may be utilized for a soft stop and in parallel with a second series for a loud stop.
