Abstract: 1296524 Ignition systems for burners UNITED GAS INDUSTRIES Ltd 18 Nov 1969 [20 Nov 1968] 54952/68 Heading F4T When a gas valve (not shown) is being opened to supply gas to a burner, a switch 10 is closed to charge a capacitor 19 with current rectified by a diode 21, the capacitor discharging through the primary of a transformer 16 when a thyristor 18 is triggered to cause sparking at a gap 17 connected across the transformer secondary. The gas valve has a control spindle 22 slidingly connected to a control knob 23 which must be pushed to unlock the spindle 22 prior to rotation for opening the valve. This pushing causes the knob 23 to abut an operating member 29 which urges a moving contact 11 of the switch 10 against a contact 13 to charge the capacitor 19. When the valve has been opened and the knob 23 released, the knob 23 is urged outwardly by a spring 27 to allow the moving contact 11 to be spring urged against a contact 12 to connect the capacitor 19 to the trigger of the thyristor 18 to trigger same. Alternatively (Fig. 2,) the thyristor trigger is connected to the current supply, but bypassing the diode 21, so that the thyristor is triggered on alternate half-cycles.

Abstract: 1296869 Photographic cameras EASTMAN KODAK CO 2 Nov 1970 [3 Nov 1969] 52018/70 Heading G2A A camera having a shutter as in Patent No 1238324 is provided with a holder 28 for a percussive flash unit, and with a flash and speed control assembly which in a first position results in a first shutter speed and in a second position results in a second shutter speed and in flash lamp firing, the second position being set automatically on insertion of a unit. The flash and speed control assembly consists of lever 12, 18  held against clockwise rotation (as seen) by pins 13, 22 respectively when no flash unit is present, Fig.1 (not shown). On camera operation, a driver 9 rotates shutter blades 2, 3 anti-clockwise, (as seen) until an arm 18a stops their opening  movement by engaging surfaces 2e, 3d of the  blades. The blades are returned by a spring 8 acting on a tab 3a. Insertion of a flash unit pivots the levers 12, 18 to the solid line positions shown, thereby moving the arm 18a out of the path of the surfaces 2e, 3d. Thus when the camera is operated, the blade 3 is free to move to the position shown, i.e. until it is stopped and returned by the spring 8. The blade 2; on reaching its solid line position, engages the arm 18a and pivots the lever 18 anti-clockwise (as seen) to its dotted line position. This movement raises a pin 20 and hence an ignition bar 19 to free a striker 26a. Return movement of the blade 3 also returns the blade 2 by means of a tab 3b engaging an edge 2e.

Abstract: 1305083 Valves D J GOLDSMITH and D F PRATT 24 Feb 1970 8885/70 Addition to 1239416 Heading F2V [Also in Division G1] The thermostatic mixing valve disclosed in parent Specification is modified so that the thermal control means is operable even when the flow control means is in the "off" position. In one embodiment, the housing has hot and cold water inlets H, C, and a mixed outlet 102. The ratio of the flows to the outlet is controlled by a sleeve 132 actuated by a temperature responsive element comprising a coiled coil 104 made of laminated strip material constituted by either a bi-metal or the equivalent in plastics material. The sleeve 132 slides on a tubular member 103 which is itself axially movable and which extends through the coiled coil and carrier at one end a valve member 113 co-operating with a seat 110 to control the flow of hot water to the port 125 of the sleeve valve. At the other end of the member 103, an axially movable valve member 120 co-operates with a seat 130 to control the flow of cold water. On-off and volume adjustment is through a knob 123 which through a screw 122 moves the member 120 axially allowing the tubular member 103 to move to the right under the influence of a spring 117, thereby allowing the admission of hot water. Due to a barrier 124 in the member 103, positioned between the hot and cold inlets, the member 103 subsequently floats between the seats 110 and 120 in accordance with the difference between the pressures of the two supplies. Temperature adjustment is achieved by a knob 114 which moves axially a member 107 and thus one end of the thermal element 104 via threaded member 109. The valve member 113 is free to rotate with the seat 110 so that it is possible to adjust the knob 114 when the cold inlet is closed. In a second embodiment, Fig. 3 (not shown), the tubular member forms the rotatable part that effects the temperature adjustment, instead of being axially movable to effect flow control. Flow control is effected by a double-beat lift valve controlling the two inlets.

Abstract: 1325193 Digital signal generator POST OFFICE 16 Aug 1971 [18 May 1970] 23863/70 Heading G4H A digital signal generator used for testing P.C.M. systems produces a series of binary numbers representing successive amplitudes of a sine or cosine wave of a selected frequency and amplitude via a successive adjustment of a piece-wise linear approximation, and employs a counter 7 and logic means operating on the output of the counter to produce, when the counter is driven at a steady rate by a clock source and controller 6, 8, a sequence of binary numbers representing equispaced points of a waveform consisting of at least two straight line sections formed end to end, the n<SP>th</SP> section having a slope 1 # n # p and wherein the n<SP>th</SP> section occurs for a time 1 # n # p-1, the p<SP>th</SP> section occurring for a time #, T being constants. The counter 7, Fig. 3, not shown, comprises a chain of bi-stable devices interconnected by monostable devices such that when a first bi-stable of the chain is driven by the clock source the n<SP>th</SP> stage will be set or reset at twice the rate of the (n + 1)th stage, thus the counter is adapted to be advanced from zero to a maximum and reset itself to zero. At this point a logic circuit including a further bi-stable selects the complement of the output and the counter counts steadily back to zero. A further bi-stable indicates the sign of the count and hence a triangular waveform is generated in the form of the sequence of binary numbers. The output of the counter 7 is modified at 9 by a logic circuit comprising a combination of AND, OR gates, interconnections of counter output bit channels with other preceding outputs, and inverters, and a sequence of binary numbers of the properties defined above is produced. This sequence is further modified by a logic circuit 10 and the final sequence represents a sine wave to the accuracy required. Each binary number in the sequence is then multiplied by a factor e.g. 1À5 at 13 which circuit comprises a plurality of shift registers used as binary dividers which may be selectively switched into the circuit and their outputs added to the original number to produce the multiplication. The 11 digit sequence is then compressed to a 7 digit output and converted to a series at 11 and read-out at 14 under suitable clock control 129, 130. A plurality of the bi-stable stages of the counter 7 may be selectively driven by the control 8 and this renders adjustable the frequency of the output sine wave and hence frequency modulation may be employed. Amplitude modulation may be employed by varying the multiplication factor at 13.

Abstract: 1331054 Lathes; tool changing ALFRED HERBERT Ltd 2 Oct 1970 [9 Oct 1969] 49570/69 Headings B3B and B3T In a machine tool, such as a lathe, having tool changing means there is provided a rotary tool magazine 16 on which are mounted a plurality of tool carriers 19 from which successive tools can be transferred by a transfer unit 45 and located in a tool mounting 17 on the machine slide 15 in readiness for operation. Each of the tool carriers on the magazine has a guide track 19a with which a tool, having a complementary track portion is clampably engageable. The tool mounting 17 has a corresponding guide track which is alignable with that on the tool carrier, whereby the tools can be moved by the transfer means 45 from the carrier to the mounting and vice versa, the transfer means moving parallel to the track. The transfer means is provided with a further guide track 51 which is perpendicular to the alignable track and which is engageable with a further portion of a tool when the transfer means is in co-operation with the magazine and by the engagement between the complementary tracks the respective tool is moved by the transfer means. The tool mounting 17 on the slide 15 is provided with an annular toothed ring which is engageable with a corresponding ring on the tool. A fluidactuated piston displaceable only along an axis at right angles to the guide track is further provided in the slide 15 at the tool mounting, whereby the tool may be drawn towards the mounting to engage the co-operating toothed rings and thus rigidly clamp the tool to the mounting. The piston has a tapered portion which engages balls which are urged radially against an abutment to wedge the piston in the clamped position. Fluid pressure applied to the reverse side of the piston effects release of the piston prior to a tool changing operation and which is retained in the released position by a spring. Prior to clamping the tool in the mounting it may be rotated about the axis of the piston by a fluid actuated rack member 36 to permit the orientation of the tool in any required position. When the tool to be clamped in the mounting is of the rotary type; drive means 41 is provided by way of gearing from a fluid motor on the machine slide 15. In an alternative embodiment shown in Fig. 4, the magazine is in the form of a plurality of trolleys 160 movable along a continuous track 161 which is located behind the bed 111 of the lathe. The track is interrupted to one position only and which can be bridged to permit the traverse of the tool carriers on the trolleys by a reciprocatable transfer means 163, the bed being provided with a window 174 with a shutter 175 which is opened and closed by an actuator to permit the transfer of tools to and from the magazine to the tool mounting 117 where the tools are clamped as previously described.
