Filed: 1951-06-04
Abstract: 706,122. Chain hoists. COFFING, J. R. June 4, 1951, No. 13221/51. Class 78 (5) Handle 84 journalled around shaft 65 carries pawl 87 spring pressed against ratchet 68 so that anti-clockwise rotation of the reciprocating handle drives the ratchet, and raises load chain 70 over load wheel 69. Holding pawl 71 cooperates with the ratchet to prevent the back movement of the load chain, and may be withdrawn therefrom by rotation of rotatable head 78. To lower ; head 78 is set to withdraw pawl 71, so that the weight of the load presses against pawl 87. The handle, therefore, is raised to allow the lowering till pin 104 (fixed on pawl 87) abuts face 102 of rotatable ring 97 and causes said ring to rotate so that the slot 99 in the ring forces pawl 71 to engage ratchet 68 to hold the load whilst the handle is brought back anti-clockwise to its original position a second pin 94 on pawl 87 being caught in notch 92 of latch 91 (carried by the handle) so that as the handle is brought back the pawl 87 is kept clear of the ratchet until latch 91 strikes projection 107 and releases said pawl. Projection 105 on ring 97 allows the handle to be operated on the opposite (right-hand) side of the load wheel. To free the chain, handle 84 is raised (as above), pawl 71 being already withdrawn and then lowered so that pin 94 is caught by latch 91. The chain is then free. Projection 107 may be temporarily withdrawn to allow the handle to be swung over to be operated in the opposite (right-hand) position referred to.

Filed: 1972-03-21
Abstract: 1326178 Optical object alignment KASPER INSTRUMENTS Inc 21 March 1972 [22 March 1971] 13223/72 Heading H4D In apparatus for automatically aligning a semi-conductor wafer 11 with a mask 16, Fig. 1 in the manufacture of integrated circuit devices, the mask 16 and wafer 11 are each provided with pairs of alignment patterns 17, 18 and 11, 12, the wafer pattern co-operating with the mask pattern in a unique visual manner to signify alignment. Photoelectric scanning means 31, 36 automatically scan the pattern areas and producing output signals indicative of the relative position of the wafer and mask patterns. Logic circuitry in response to said scan output signals compute formulae responsive to any misalignment, which are utilized to produce control signals for driving motor means 26-28 to produce relative movement between the mask and wafer to bring them into alignment. Several separate alignment cycles are provided, if needed, for zeroing in on a finalized alignment. A tolerance selection means is provided for permitting a variation in final alignment tolerance. An initial coarse visual alignment step is used. The desired relative positions of single-line cross-marks 12 and 13 and double line crossmarks 17, 18 are with lines 14, 15 half way between double lines 19, 21 and 22, 23 respectively, Fig. 2. The scanning means comprises a single photodetector 36 behind a moving belt shutter 31, having in order of use, slit apertures 32, 34, 33, 35, respectively detecting lines: 14, 19, 21 (12, 17); 14, 19, 21 (13, 18); 15, 22, 23 (12, 17); 15, 22, 23 (17, 18). Photodetectors 39 and 40 co-operate with respective holes 37 and 38 to give pulse indications of which line is being scanned by which aperture. After pulse shaping in means 45, pulses 41 (line 14); 42 (19), 43 (21) Fig. 3 are produced and corresponding interpulses A<SP>1</SP>-C<SP>11</SP> are produced by generators 49, 53. The patterns are scanned twice, the first time to establish the direction of the pattern misalignment and the second time to establish the exact amounts of the misalignment. The tolerance within which alignment will be accepted is adjustable. Pulses A<SP>1</SP>-C<SP>1</SP>, A<SP>111</SP>-C<SP>111</SP>, for each of the four scans (four slits 33-35), one converted into three clock pulse trains. The width of pulses C<SP>1</SP> and C<SP>11</SP> are constant, being indicative of the spacing of lines 19 and 21 and being represented to by 2,000 clock pulses in the computing circuitry. The three clock pulse trains are fed to respective ones of three UP/DOWN counters in such manner that the direction of misalignment of the patterns is given by that counter storing the C<SP>1</SP>, C<SP>11</SP> clock pulse count, whilst the amount of the misalignment is given by the other counter contents. Extensive circuit details are given.

Drawings to Specification. [Class 40 (iii).] A photo-electric cell is so constructed that the photo-electrons pass directly from the photo-electric material into the electrodes without traversing a vacuum. Two copper or other plate electrodes, one of which is semitransparent, are separated by a thin layer of " semi-conducting material of unipolar conductivity " such as cuprous oxide a few molecules in thickness, and the cell is sealed up in a celluloid or glass coating. The Specification states that when light falls on the transparent electrode a photo-electric effect takes place so as to set up a potential difference between the electrodes, that the threshold potential across the interfaces between the layers is less than that at a surface in vacuo, and that the copper cell is sensitive to infra-red radiation of wavelength 0À001 mm. It may be used as a light-actuated relay, for television, in connection with talking films, photophones, colour sorting apparatus, photometers or radiation pyrometers, or as a means for converting solar radiation into electric energy for charging accumulators. The Specification refers to a pub. lished research by Griger showing that argentite (Ag2S) crystals when clamped between metal electrodes of which one is illuminated give rise to an e.m.f.

Title: Improvements in perspective sound systems
IPC: H04R3/12
Filed: 1954-05-07
Abstract: 772,258. Binaural and reverberation systems. PERSPECTA SOUND, Inc. May 7,1954 [Oct. 8, 1953], No. 13433/54. Class 40 (4). A system for producing spatial sound effects from a single programme signal comprises means for injecting into the signal a plurality of lowfrequency control signals, means for recording the composite signal, reproducing the composite signal and separating the programme from the control signals, and means for controlling the amplitude of the programme signal fed to a number of reproducers under the control of the control signals. A signal from a single microphone 14, Fig. 1, is mixed at 20 with separate low-frequency signals from control-frequency sources 17, 18, 19, the amplitudes of the control frequencies being controlled manually. The composite signal is recorded at 30. The signal is reproduced at 35, Fig. 2, and the control frequencies are filtered out at 93, rectified at 94 and used to control the gain of amplifiers 32 feeding spaced loud-speakers 34. The signal to one of the loudspeakers is delayed by a system such as shown schematically in Fig. 3 to give a reverberation effect. The control frequencies are preferably of low amplitude and sinusoidal in character so that their harmonics do not affect the programme signal. The system is applicable to theatres using a single loudspeaker, the spatial effect being lost but no deleterious effect being produced.

Title: Improvements relating to the control of electric motor-generators
Filed: 1952-05-27
Abstract: 714,970. Control of D.C. motors. BENDIX AVIATION CORPORATION. May 27, 1952 [June 29, 1951], No. 13453/52. Class 38(3) [Also in Group XXXV] Relates to means for reducing the starting current of a D.C. motor 5 which drives an alternator 14 having a rotor winding 13 and a stator winding 15. The motor has an armature 6, shunt field winding 7, and regulating field winding 8 as well as a starting series field winding 9, main series winding 10, and interpole winding 11. A carbon pile regulator 24 is connectable in series with the alternator exciting winding 13 and is biased by spring 30 to increase the voltage output of the alternator, an electromagnetic winding 31 opposing the effect of the spring and being energized in accordance with the voltage across the winding 15. A frequency regulator 21 has a carbon pile element 41 connected in series with the motor regulating winding 8 and biased by spring 40 in a direction to decrease the speed of the motor. Electromagnetic windings 44, 45, 46, and the winding 20 co-operate to bias armature 38 in a direction opposing the spring 40, the winding 20 being connected in series with the alternator exciting winding 13 and the regulator 24. The main control winding 44 is responsive to the output of the alternator and tends to increase the speed of the motor in response to such voltage. The opposing windings 45, 46, are energized from rectifiers 55, 61, which are connected across the winding 15 in series with resonant circuits 58, 63, respectively. The resonant circuits are separately adjusted to resonate at frequencies slightly above and below the operating value, so that a shift in frequency from the desired value will be corrected by the appropriate energization of the windings 45, 46. A switch 27 is closed during the starting operation of the motor when its back electromotive force reaches a predetermined value. This causes closure of switch 75 to short-circuit the starting winding 9 which is of fine wire and is included during the initial stages of starting for increasing the motor field and reducing the starting current. Closure of the switch 27, in addition, actuates a switch 81 to connect the alternator to the output line 82, the voltage regulator 24 being also included in circuit to allow the operating voltage of the alternator to be attained.

Abstract: 558,314. Valve circuits for wireless reception. REDIFFUSION, Ltd., and EXWOOD, M. Sept. 29, 1942, No. 13624. [Class 40 (v)] Distortion due to selective fading in the reception of modulated carrier waves is limited by introducing a local wave before the demodulating stage and having the same frequency as the carrier being dealt with and modifying from time to time the phase of this wave relatively to the mean of the sidebands of the carrier wave. The Figure shows apparatus adapted to be connected between an aerial and a terminal 2 connected to a receiver comprising an oscillator 5 feeding a mixer 11 to which the incoming wave is applied through an amplifier 3. A voltage dependent on the relative phases of these waves is derived from a phase -discriminator 7 fed through a limiter 4 and a trap circuit 6, and is applied to a variable reactance 8 associated with the oscillator 5. The phase varying control may operate at a subaudible or supersonic frequency and comprise a motor driven rotary variable condenser which may periodically vary the tuning of the trap circuits 9 or 10 or the variable reactance 8 may be varied by a periodically varying voltage. Alternatively the local wave may be introduced in the intermediate frequency stage of a superheterodyne receiver.
