Abstract: 1485446 I C engine throttle control DAIMLER-BENZ AG 8 Nov 1974 [16 Nov 1973] 48524/74 Heading FIB An I.C. engine with a control device for limiting its speed by closing a throttle valve 2 in its air or combustible mixture intake duct 1 in dependence on the vacuum in the duct downstream of the throttle valve comprises a servo device 12 responsive to the vacuum and adapted to move the throttle valve 2 in response thereto in the closing direction against the resistance of a spring 17 which is in some circumstances at least dependent on the position of said valve, the valve being so movable irrespective of its instantaneous operative position. Valve 2 is rigid with an intermediate lever 4 biased in the opening direction of the valve by spring 5 and biased in the closing direction by spring 8 acting by way of part 7, the valve being opened by movement of linkage 9 to the right. When the vacuum downstream of valve 2 exceeds a certain value (as a result of engine speed increasing beyond a value depending on the throttle valve opening), servo device 12 causes lever 15 to rotate anticlockwise until a part 16 engages lever 4 and moves throttle valve 2 in its closing direction. The operating characteristics of the control device depend on the pre-stressing of compression spring 17 determined by the position of a setting member 18. In other embodiments Figs. 2, 3 and 4 (not shown), the end of spring 17 remote from member 18 abuts against element 19 slidable on rod 14 and linked respectively to lever 6, lever 4 and lever 15.

Title: Integrated attenuation elements
IPC: H01L29/86
Filed: 1972-10-23
Abstract: 1389349 Semiconductor devices SIEMENS AG 23 Oct 1972 [24 Jan 1972] 48668/72 Heading H1K An attenuation circuit comprises a N-type semiconductor body 1 of e.g. P doped Si with P-type Boron doped zones 4, 5, 6 and N-type phosphorus-doped zone 3 on its opposed face with control electrode 13. Zones 4, 5, 6 have electrodes 7, 8, 9 and are aligned in a row (Fig. 1). ). Alternatively a further phosphorus-doped N-type zone is formed adjacent zone 4 with an electrode thereon (Fig. 2, not shown) or such zone may be provided in the vicinity of zone 4 but on the opposed face and separately from the zone 3 and electrode 14 (Fig. 3, not shown). In operation (Fig. 4) a HF input is capacitance coupled to input zone 4 also resistance coupled to a control signal between terminal 44 and earth, while output zone 5 is capacitance to the control signal source. Control zone 6 is resistance capacitance coupled to a further control signal between terminal 47 and earth. Contact electrode 13 on the reverse face is earthed over HF blocking choke 52. Application of control voltage (which may be DC or low frequency AC) positively to earth at 44 biases PN junctions between 4, 5 and 2 into the pass direction to diffuse holes from 4, 5 into region 2 and electrons from 3 into region 2. This lowers the differential resistance between 4, 5 and 3, and if a zero or -ve voltage is applied to terminal 47 the PN junction between zone 6 and region 2 is blocked. The HF signal at 40 then passes across PN junctions 4, 5 to 50 without attenuation. A zero or -ve voltage at terminal 44 blocks PN junctions between 4, 5 and 2 and a positive control voltage at terminal 47 pass biases the PN junction between zone 6'and region 2 to inject holes from zone 6 and electrons from zone 5 into region 2, so as to lower the differential resistance between zones 6 and 3. The HF input at 40 passes to 50 only over the blocking layer capacitance of the PN junction 2, 4 and is shunted to earth over capacitance 49, so that the output signal is highly attenuated to a degree variable by a control signal. Control zone 6 also acts as a capacitance screen between input zone 4 and output zone 5. Zone 15 reduces mis-match between the input of the device and an input line to terminal 40 in response to a negative control voltage applied thereto over terminal 42 to draw off the control current which flows across input zone 4, so that the differential resistance at signal frequency between terminals 10, 17 equals the line surge impedance. A matching resistor may also be connected in series with the connection to zone 15 (Fig. 5, not shown). Plural such attenuation elements in a single semiconductor body may be connected in series, and the passive components may be integrated with the body.

Abstract: 1,204,500. Photographic shutter mechanisms. EASTMAN KODAK CO. Oct.30, 1967 [Oct.31, 1966], No.49174/67. Heading G2A. A camera shutter has an open period depending on the force exerted on a shutter blade by an electromagnet, the current through which is dependant on the light falling on an exposure meter. As shown in Fig.1, depression of the shutter release 3 releases a plate 4 which moves under a spring bias 5. The shutter blade 2 is subjected to the increasing bias of a spring 10 as the plate 4 moves, but is held in the position covering the aperture 1 until the spring force exceeds the force exerted on the blade 2 by an electromagnet 6, when it is released and the aperture is uncovered until the projecting part of plate 4 covers it again. The current through the electromagnet 6 is dependant on a photo-resistor 8 in the circuit of the electromagnet, which circuit may also include a flashlamp 20, actuated by the movement of plate 4. In an alternative form, Figs. 5-7 (not shown), the shutter blade moves immediately on depression of the release 3 to uncover the aperture 1, but its motion is retarded as it abuts a pivoted lever, one end of which is attracted to the electromagnet 6.

Abstract: 1,185,726. Fluid-pressure servomotor systems. BORG-WARNER CORP. Nov.6, 1967 [Nov.16, 1966], No.50407/67. Heading G3P. A shock pressure occurring in either line 38 or line 40 connecting the opposite ends of a double-acting motor cylinder 24 to a directional spool valve 42 is relieved through a passage 62 inter-connecting the lines and normally closed at its ends by identical pilot operated relief valves 70, 76 arranged to open at increasingly high pressure with increasing static pressure. The relief valve 70 comprises abutting hollow plungers 108, 110 slidable in a bore 112. The plunger 108 has an integral poppet 68 normally closing the passage 62 and contains a pilot valve 114 biased by a spring 116 to close a displaceable tube 122 having a flange 124 slidable in a bore formed in the plunger 110. The compression of the pilot spring 116 increases with increasing pressure due to the static pressure acting on the flange 124 displacing the tube 122. Pressure in the line 40 acts through passages 128, 130, 132 on the end of the plunger 110 and through passage 58 on the end of the plunger 108 which is of smaller effective area than the plunger 110 to maintain the valve 70 closed. When the pressure rises, the pilot valve 114 opens to exhaust fluid acting on the plunger 110 to a return passage 137, 54 and the plungers thus move to the left opening the passage 62. Pressure in passage 62 forces the poppet 74 of the valve 76 away from its seat 72. The spool valve 42 has an axial bore 90 in which slides an anti-cavitation shuttle 80 which automatically moves to connect inlet pressure in the port 52 to the passage 58 or 60 experiencing the low pressure.

Abstract: 1329278 Infra-red television camera BOFORS AB 29 Oct 1970 [29 Oct 1969] 51490/70 Heading H4F An infra-red camera (Fig. 1, not shown) comprises a rotating hexagonal drum having a mirror on each face which scans the incoming infra-red radiation across a rocking mirror which vertically scans the radiation on to a concave mirror and hence to a detector 7, Fig. 2. As the horizontal aperture is only of the order of 25 degrees, for about 80% of the time the mirrors on the hexagonal drum are scanning the interior walls of the camera, which heat up during operation, thus affecting the output reading on a picture display tube. The output from the detector 7 is amplified in a preamplifier 8 and intermediate amplifier 9, the amplifiers 8 and 9 being provided with a D.C. feed-back L fed with a reference voltage U1. The amplified output which is dependent on the mean value of the signal from 7 is fed into a circuit 10 which renders the output signal independent of the background input signal and the output is passed via a switch 12 which can change the output between the direct output or that from an invertor 11, The circuit 10 comprises an integrator which produces a compensating signal and is gated to receive the signal from the input 10a during the background part of the signal. The integrator is connected via a resistor to the input of a video amplifier to which is also connected via a capacitor and resistor the signal from the input 10a and a reference voltage U2, the video amplifier being connected with negative feedback by a resistor. The values of the resistors may be varied to make the output independent of the background or they may be adjusted to make the output dependent on the background to varying degrees. An invertor may be included in the circuit 10 between the integrator and video amplifier. The integrator may alternatively be gated to have an input during the signal period of each cycle, or it may be gated to have an input one or more times in a group of line cycles.
