Title: Washing machine
IPC: D06F15/00
Filed: 1965-04-14
Abstract: 1,107,532. Washing machines. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 14 April, 1965 [14 April, 1964; 11 March, 1965], No. 16028/65. Heading D1A.  A washing machine comprises a vertical cylindrical casing 1 whose top is closed by a lid 2 and coaxial therewith a cylindrical piston connected to the casing at a distance from the bottom by a diaphragm, means being provided for supplying operating liquid to the space beneath the piston and diaphragm to produce axial movement of the piston. The stainless steel washing vessel 1 is externally heat insulated and is lined with a perforated plastic cylinder 27 which may be corrugated and is spaced from vessel 1 by radial ribs. A stationary cylinder 3 concentric with vessel 1 is made of stainless steel reinforced plastics and is secured to the washing machine base by tie rods 9. One edge of a substantially cylindrical diaphragm 4 is secured to the upper end of cylinder 3 while its other edge is secured to piston 17. The plastic dome-shaped piston 17 is raised by a dome-shaped sheet metal part 18 which with a guide cylinder 15 can be telescoped onto guide cylinder 12 concentric with cylinder 3. Wash suds 24 are heated by heating ring 23. Pipes 28, 29, 35 vent to the atmosphere respectively the interior of piston 17, the space between the top of cylinder 3 and diaphragm 4. Pipes 28, 35 are connected to a common pipe 30 controlled by a cock 36 which is closed when the piston and diaphragm have been filled initially. The water in this space is maintained under the control of a float operated valve 31 and a valve 33. The spaces between diaphragm 4 and cylinder 3 and between cylinder 3 and wall 43 are filled initially from the main through pipe 39, the spaces being connected through a centrifugal pump 41. Pipe 39 is of smaller cross-section than pipes 28, 35 and 30 to prevent the piston from being raised during filling. The pump 41 has as large a cross-section as possible and is as low as possible in the machine so that it can pump the operating water efficiently from the space between cylinder 3 and wall 43 to the space behind the piston and diaphragm. The machine is normally vented to the atmosphere through valve 44 but this is closed when squeezing out is completed so that the ends are forced out through pipe 48 instead of by a special pump. Before lid 2 can be removed it must be released by piston 17 at its highest point so that the washing can be placed round the piston. During washing the piston is raised and lowered after which the washing is squeezed out by increased pressure on the piston, e.g. by changing the motor operating the pump. Rinsing then takes place in the same way as the washing. The machine may be controlled by switch mechanism driven by a synchronous motor.

Title: Improvements in or relating to telecommunication systems
IPC: H04B3/20
Filed: 1942-11-14
Abstract: 561,405. Two way repeaters. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., GILLINGS, C., and COWLEY, P. E. A. Nov. 14, 1942, No. 16128. [Class 40 (iv)] In a terminating repeater comprising differentially controlled attenuation networks in the respective paths, the control current for increasing the attenuation of the go-path is obtained from the balancing resistance of a hybrid transformer in the circuit of the returnpath amplifier. By this means, a signal arriving over the two-wire line when the gopath is biassed against it is prevented from maintaining this bias against itself. The Provisional Specification includes another arrangement with the same object. In one arrangement, Fig. 1, signals from the two-wire line 2WL after amplification at GA are fed to the line GO. A portion, rectified at SRRA, alters the bias on the return path amplifier RA to vary its plate current and so bring the return path attenuator RVAN to its highattenuation state. Signals from the return path RN after amplification at RA are fed to the two-wire line and also produce a current in the line-balancing circuit which includes resistance YD and an input transformer for a rectifier SRGA. Currents rectified by SRGA alter the plate current of the amplifier GA and so bring the go-path attenuator GVAN to its high-attenuation condition. In a modification, Fig. 2 (not shown), the output of amplifier RA is coupled to the hybrid transformer through a second hybrid transformer and the control currents are derived from the balance circuit of the latter. In another arrangement, Fig. 3, which is described only in the Provisional Specification, the control potentials are obtained from additional grids in the main amplifier tubes. When, for example, a signal comes in over the return line RN an alternating voltage is produced across resistance YG connected to this additional grid and is used to produce a rectified voltage for biassing the other amplifier tube and so bringing the go-path attenuator to its high attenuation condition.

Filed: 1948-06-16
Abstract: 641,527. Liquid-spring shock-absorbers. DOWTY EQUIPMENT, Ltd., and BINGHAM, A. E. June 16, 1948, No. 16231. [Class 108(iii)] A shock absorber of the kind in which resilient compression of entrapped liquid affords resistance to loads operating in tension, and expansion of the liquid is controlled by damping orifices, comprises two chambers arranged concentrically in overlapping relation, one chamber being essentially of greater volume than the other, the smaller chamber being constituted by the annular space around a piston rod extending into a cylinder at one end and carrying a piston slidable in the cylinder, the cylinder being open to atmosphere at the other end, there being one or more restrictions affording the sole communication between the two chambers, and liquid filling the larger chamber and the maximum available space in the smaller chamber. In the construction shown in Fig. 1, the larger chamber 11 is formed by an outer cylinder 12 surroundthe cylinder 13 defining the smaller chamber 10. Communication between the two chambers is by way of one or a few restricted orifices 22 and by several orifices 23. Flow through the orifices 22 is controlled by a rigid ring 24 having an annular channel 24A and a plurality of communicating ports 24B, 24C. Flow through the orifices 23 is controlled by a resilient split-ring 25 which prevents flow into the smaller chamber but permits it in the reverse direction. The end 19 of the cylinder 13 is reduced in thickness and seats on a packing ring 18 in an annular recess in the end of the outer cylinder 12. Thus liquid pressure acting on the cylinder 13 in the orifices 22, 23 produces slight axial movement of the cylinder 13 to compress the packing 18 to a greater pressure than that of the liquid. Packing gland means 15, 17 for the piston rod and piston respectively is of the unsupported area type described in Specification 539,966, [Group XXVI]. In the construction shown in Fig. 2 the larger chamber 11A is constituted by a hollow space in the piston rod 26. Fixed flow restriction means 27 are provided between the two chambers.
