Title: Communication system
IPC: H04Q5/00
Filed: 1972-05-18
Abstract: 1343002 Party line systems STANDARD TELEPHONES & CABLES Ltd 18 May 1972 [21 May 1971] 23438/72 Heading H4K A communication system including a plurality of stations connected to a common communication path has a calling arrangement wherein the calling signals comprise a total number of pulse transitions divided into groups to give a unique station code so that a decoding arrangement in the station responds to the code whereby a timing circuit is prevented from operating on receipt of the respective code by being switched into a long delay mode coincident on the receipt of inter-group pauses. In the system described the calling signal consists of seventeen pulse transitions divided into three groups by 1 second code pauses and prefaced by a 1 second start pause with a terminating 2 second ring pause followed by a single switch off pulse edge. The decoding arrangement includes an electronic, solid state counter which totals the pulse transitions so that a response is obtained for a group call where the first group of transitions is sent followed after the 1 second code pause by the remainder of the total or an all station call when all seventeen pulse transitions are sent. In the circuit arrangement an on circuit timer S is used to operate the switch 6 on receipt of a valid start pause and this provides a power supply to the decoding circuitry. The input pulses are attenuated to a suitable level and filtered in amplifier 4 and reshaped in inverter 9 so that they can be accurately counted in the counter arrangement 10, 11. The count is passed to a decoder which consists of gates connected to a strapping field in which the particular station's code groups are set up so that  an output is obtained whenever a valid code group is received. This output is used to change the time delay of off circuit timer 15 from a short to long time delay thus keeping the circuit alive during the code pause. The timer 15 is arranged to be reset whenever a pulse transition is received and thus if a code pause is received at the wrong time, i.e. another station is being called, will time out and disable the switch 6 thus shutting down the station. When the whole code is received oscillator 7 is operated during the ring pause to provide an audible alarm at the station and a ring back tone to the control station. A station can make a call to the control station by short circuiting the idle line using button 18.

Title: Improvements in or relating to washing machines
IPC: D06F31/00
Filed: 1950-09-26
Abstract: 704,336. Washing-apparatus. POENSGEN AKT.-GES., GEB. Sept. 26, 1950 [April 3, 1950], No. 23621/50. Class 138 (2) A continuously operating washing and rinsing machine having a plurality of inter-communicating containers 1 ... 8 successively traversed by the washing and rinsing water in opposite sequence to the operations performed on the articles being washed, in which a batch of articles is placed in each container and remains therein until the laundering operation is completed, is characterized in that the containers are arranged on a rotatable platform 9 and are thereby moved in a timed sequence to the various working positions, each operation always taking place at the same point. In the example eight washing containers 1 ... 8 communicate with one another through overflow pipes 10 containing three-way valves as 16,17,18. The containers are connected through valves 19 ... 26 to an annular pipe 27, through valves 28 ... 35 to an annular pipe 36, and through steam valves 37 .... 44 to an annular steam pipe 45. The pipes 27, 36 and 45 are fed from a rotary joint 46 through pipes 47, 48 and 49 respectively. Above the containers is a frame 50 carrying washing stirrers 51 or the like, and a motor 52 for centrifuging. Means 53 for introducing the washing agents is disposed above the washing container 4. A rotary head valve Figs. 4 and 5 (not shown), may be used in place of the rotary joint 46. Operation. The clothes are loaded and unloaded from each container in turn as it reaches the position of container 1 (Fig. 1). Meanwhile the articles in container 2 are being soaked in water at 40‹C. The articles in container 3 are prewashed at 60‹C. and those in container 4 are finally washed at about 80‹C. In container 5 the articles are pre-rinsed at about 60‹C., in container 6 at 40‹C. and in container 7 they are rinsed with cold water. The articles are pre-dried in container 8 by centrifuging or wringing. Cold water from annular pipe 27 and valve 24 enters container 7 and overflows through pipe 10 into container 6 where it is heated from 20‹C. to 40‹C. by steam supplied from pipe 45. It then overflows to the next container and so on to container 2 whence it discharges to waste. Separate waters may be used for the washing and rinsing stages. Thus rinsing water may be supplied to the container 7 by pipe 36 and valve 34 and discharged to waste from container 5. The height of the overflow pipe 10 in each case determines the level of liquid in the container. The washing and rinsing water may flow off continuously or intermittently. On completion of each stage, the frame 9 with the containers 1 ... 8 is moved through # revolution so that container 8 takes the place of container 1 and so on. Specification 672,755 is referred to.
