Abstract: 1,227,049. Washing machines. INDUSTRIE A. ZANUSSI S.p.A. 14 May, 1969 [16 May, 1968], No. 24716/69. Heading D1A. [Also in Division A4] A dish or laundry washing machine is provided with a drying system comprising an electric heater 1 having a supply circuit including two thermally actuated switches 4, 5 responsive to two different temperatures of the drying environment in the machine and the driving motor of a timer controlling washing, rinsing, and drying cycles, and a manually actuated member, e.g. a push button operated contact 8, which is settable in two alternative positions to cause the timer motor to initiate a drying period of predetermined duration when the drying environment is at the higher, and at the lower, respectively, of said two different temperatures. When the contact 8 is closed the heater 1 is energized through the switches 3, 4, 5, 7, 8, the timer motor 2 being short circuited. The thermally actuated switch 5 opens when the temperature of the drying environment reaches say 40C. This energizes the timer motor 2 which closes the switch 6 and opens the switch 3 so that the heater 1 continues to be energised through the switches 7, 8, 4, 6, the motor 2 being again short circuited, and when the temperature of the drying environment reaches a value, e.g. 65C, causing the switch 4 to open, the heater 1 is then connected in series with and controlled by the timer motor 2. When however, the system is operated with the switch 8 open, the opening of the switch 5 at the said lower temperature of the drying environment energizes the motor 2 to close switch 6 and open switch 3, so that the motor 2 continues to run and control the heater 1.

A method for producing on a support an image giving a stereoscopic effect when in register with a viewing screen includes preparing an at least partially lineiform reproduction from a twodimensional picture. The lineiform picture when thus prepared may be of the form shown in Fig. 2, in which, when viewed through a lenticulated screen 3, the central portion produces an image which stereoscopically appears to lie, as a B, in a plane behind the plane of the support, the border A of the picture appearing stereoscopically in the plane of the support. In one method, Fig.3, a photo-sensitive layer 7 is exposed through a grid 6 having a large number of closely spaced slits, a picture 4 being focused by a lens 5. Successive exposures are made by keeping layer 7 and grid 6 stationary and moving picture 4 and lens 5 to new positions 4<SP>1</SP>, 5<SP>1</SP>. After processing, and with the left and right eyes at positions 5, 5<SP>1</SP>, an image will be seen at position X. Alternatively, the picture is held fixed and the layer 7 moved with or without movement of lens 5. Keystone distortion may be introduced by rotation of the picture or layer between successive exposure to further enhance the stereoscopic effect. An autostereo camera may be used to produce the lineiform image.

Abstract: 1,239,367. Sheet forming. COMET INDUSTRIES Inc. 10 March, 1970 [18 March, 1969], No. 11468/70. Heading B5A. [Also in Division G3] In a thermoforming machine, the various operations of the parts of the machine are controlled by programme card 116 comprising a flat plastics plate provided with longitudinal notched ridges 118, the card being forwarded, by means of a motor driven pinion gear engaging a central rack 120, under a series of press-button switches there being one switch corresponding to each ridge. The switches are selectively closed by the notches and the various operations are thus controlled. The plate is forwarded intermittently and, during its periods of motion, the switches are closed by engagement with the notches and the operations controlled according to a pre-set time sequence dependent upon the speed of the plate. During its periods of rest the operations are controlled by sensing devices located in the machine, the sensing devices also acting to resinstate the movement of the plate when desired conditions occur so that further control is obtained from the plate. In the embodiment shown in Fig. 1, the sheet to be formed is clamped by a fixture 46 comprising four pneumatically operated clamping bars (see Fig. 5, not shown) over an aperture in a vacuum tank 24 and is heated by upper and lower radiant heaters 38, 36 reciprocable over and away from the sheet along tracks 26 and 28 by means of a pneumatically actuated lever 82. The sheet is screened from the upper heater to control the temperature of different areas of the sheet by a screen 52 carried by a frame 48 reciprocable to and from a position above the sheet along tracks 40, upon which screen a selected template 54 may be positioned. After heating, the sheet is pre-stretched by blowing and then formed between a lower mould to which vacuum is applied and an upper mould, the moulds being carried by platens 100 and 98, respectively, reciprocable along racks 92 by drive pinions 102. After moulding, the moulded article is ejected by a blast of air through the lower mould. To control the sequence of operations, the card is forwarded until a first switch is closed to admit compressed air to the vacuum tank and movement of the card is continued until second and third switches are closed to start the heating, movement of the card being arrested at this point. After the sheet has been pre-stretched and heated to the required degree as determined by a photo-cell device and a temperature sensing device, the temperature sensing device arrests the heating and causes the plate to be further forwarded to bring further notches under further switches to control the rest of the forming operation. Sets of screen template/programme card pairs may be stored, each pair corresponding to the manufacture of a different type of article.

In a permanent data store comprising a number of stacked insulating boards S 1 -S n  each having printed wiring on one side, the boards being provided with holes K through which read wires Z are passed, the printed circuit loops L are selectively opened at A or O in order to store data and a capacitor C is connected between the input terminals of the uppermost and lowermost boards in order to compensate for the fact that the parasitic capacitance of these boards is different from that of the remainder since they each have only one neighbouring board whereas the remainder have two. As shown, the printed tracks B 11  and B 31  are both connected to track B 21 , this pattern being repeated along each of the boards, so that R/3 capacitors are required where R is the total number of tracks on each board. In a modification the boards are connected together in groups which are formed by interconnecting corresponding input terminals of the boards within each group. Thus when the uppermost and lowermost boards of the stack are connected via a capacitor the uppermost and lowermost groups are in fact connected together.
