Title: Improvements in or relating to range finders
IPC: G01C3/12
Filed: 1945-12-20
Abstract: 605,488. Range-finders. KODAK, Ltd. Dec. 20, 1945, No. 34571. Convention date, March 13, 1943. [Class 97 (i)] A coincidence or stereoscopic range-finder has a single objective which includes a reflecting-transmitting surface and has the same power for reflected as for transmitted beams, the light from two spaced windows being directed by suitable reflectors upon opposite sides of the objective which thereby forms images in a comparison field one by reflected and the other by transmitted light, means being provided to effect coincidence. As shown in Fig. 3, the range-finder comprises reflectors 31, 32 and a semi-transparent reflector 30 directing light on to opposite sides of an objective 33 having a central reflecting- transmitting element 34 formed by interference layers, the reflected and transmitted beams being of different colours. The beam from the mirror 30, reflected by the element 34 back through half of the objective and the beam from reflectors 31, 32 transmitted thereby pass via erecting prisms 35 to a comparison plane 36, where the images are viewed through eye-piece 37. Coincidence is affected by rotating the mirror 30 about a pivot 48. The finder may incorporate the coincidence line and fiducial mark system described in Specification 605,486. An index 40 in the field 36 is illuminated by a suitable lamp light from which passes via prisms 35 to be directed through an aperture 41 in the mirror 30. Thence the beam is transmitted by the objective to reflector 32, and thence via bevelled edges 43, 44 on reflectors 31, 30 respectively is reflected to the objective 33 and returned to form an image in the plane 36 via the reflecting element 34 and the prisms 35, any maladjustment being indicated on a scale in the field 36. The prism system 35 may be omitted and the beams reflected by mirrors 31, 32 and 30 may be inclined to the axis of the objective. The invention may be applied to the stereo rangefinder described in Specifications 603,475 and 605,481. Specifications 605,482, 605,483, 605,484 and 605,485 also are referred to.

Title: Add-subtract counter
IPC: G06M1/38
Filed: 1967-07-28
Abstract: 1,134,799. Counters. E. W. BLISS CO. 28 July, 1967 [24 Aug., 1966], No. 34711/67. Heading G4D. An add-subtract counter comprises an add ratchet wheel and a subtract ratchet wheel which are prevented from being driven in the undesired direction when the add or subtract pawl is effective. The subtract solenoid I rocks double-armed pawl G counter-clockwise about pivot 76 so that the shorter arm 70 advances star-shaped ratchet wheel E half a step clockwise, as permitted by sprung detent K. Any tendency to rotate in the opposite direction is prevented by the edge 96 of detent K. De-energization of the solenoid permits spring 78 to rock the pawl G clockwise so that the longer arm 72 advances the wheel E another half-step. Similarly the add solenoid H co-operates with pawl F, star-wheel D and detent J. The two star-wheels drive opposite sides of a differential C, the output of which drives the lowest order of a counter, Fig. 2. The units wheel 28 is associated with a second units wheel 30 set to display one more. Both unit wheels drive tens wheels 32, 34 through conventional transfer wheels 40. When the wheels 28, 32 display 00 cams 46, 50 reverse switches SW2, SW3 so that input pulses operate the counter in forward direction only. At a count display on 28, 32 of 99 the wheels 30, 34 display 00 and cams 58, 62 reverse switch SW1 so that the counter operates in reverse direction only. Switch SW3 controls an external load.

Abstract: 1379848 Electro-medical apparatus PEAK TECHNOLOGIES Ltd 12 July 1973 [25 July 1972] 34777/72 Addition to 1378754 Heading G1N In a system for monitoring cyclic movements of a patient, e.g. movements of the chest wall due to respiration, as in the parent Specification in which a movement sensitive field envelopes at least part of the patient and variations in the field are monitored, a signal is provided for each successive group of a predetermined number of movement cycles and an inclination is given in response to the absence of such a signal in a predetermined interval from the preceding signal. As shown, variations in the field are sensed by a receiver RX to provide a signal A, Fig.6, this signal being applied to a Schmidt trigger to provide squarewave pulses. These squarewave pulses are applied to a pump circuit which includes a capacitor which is charged as shown in Fig.6-B. The output of the pump circuit is applied to a Schmidt trigger which provides an output signal, Fig.6-C, when the pump output reaches a predetermined level after three pulses. The output signal resets the pump circuit, via an inverter and is applied to reset a timer T. If the timer output signal, Fig.6-D, is allowed to fall to a pre-set level then an alarm is energized. This indicates that a Schmidt output signal has not been provided within a predetermined interval from the preceding signal. Details of the circuitry are described with reference to Figs.1-4 (not shown).

Filed: 1946-11-23
Abstract: 624,114. Duplex pulse signalling; pulse modulation. McGUIRE, J. H. Nov. 23, 1946, No. 34815. [Class 40 (v)] In a duplex pulse communication system using a common carrier frequency both ways with pulse phase modulation and receiver suppression during transmission, the pulse repetition frequencies are independent and control the frequency of a reference phase generator at the distant receiver, and a " memory " phase demodulator at each receiver provides uninterrupted output of the demodulator during receiver suppression. The generator RO may be a transitron Miller integrator saw-tooth generator with bias and therefore frequency controlled by a feedback channel FBC and voltage output fed via C2, R7, A, B to a " memory " condenser C6 at instants when double diodes V2, V3 are rendered conducting by pulses fed through a transformer T1. The stepped voltage passes to an amplifier AC and audio output filter LPF and simultaneously controls the frequency of generator RO by feedback proportional to any drift between the P.R.F. and generator and amplified by valves V4.

Title: Improvements in or relating to aircraft structures
IPC: B64C3/00
Filed: 1934-12-05
Abstract: 445,437. Aircraft wing structures. BRISTOL AEROPLANE CO., Ltd., and RUSSELL, A. E., Filton House, Bristol. Dec. 5, 1934, No. 34987. [Class 4] Relates to aircraft wings of the type comprising a single spar designed to resist the bending forces on the wing and a box-like structure designed to resist the major part of the torsional forces on the wing. A single metal spar 10, Fig. 1, is arranged at the deepest point of the wing section. Spaced from each side of spar 10 are longitudinal girders comprising vertical walls 12 and flanges 13 connected to rigid upper and lower metal skins 14, 15, this constituting a torsion resisting box. Spar 10 is connected to parts 14, 15 by its flanges 11. Spar 10 is continuous across the body 19, Fig. 2, whilst the inner ends of the box flanges of girders 11 are connected by diagonal braces 16 to the bottom flanges at which points of connection the girders are pivoted to body 19. The torsion box is thus prevented from resisting bending forces on the wing. The stresses produced between diagonal braces 16 and flanges 13 are resisted by a fore- and-aft bulkhead 20, Fig. 2, to which flanges 13 are fastened and which serves also to transfer the torsion in skins 14, 15 to pivotal attachments 17,18. Spar 10 terminates outwardly at similar bulkheads 21. Ribs designed to redistribute the bending loads may be provided between the spar end and the wing tip.

Title: Code discriminator
IPC: G06K7/14
Filed: 1976-08-23
Abstract: 1519256 Selective signalling; bar code reader MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 Aug 1976 [2 Sept 1975] 35060/76 Headings G4H and G4M A code discriminator, for a bar code including a guard pattern and characters, comprises means for scanning the code and transforming the code into an electric signal, means for counting and averaging the width of a bar and a space in the guard pattern and using the average width in sampling the first character following the guard pattern, and means for counting and dividing the total width of a character and sampling the next character. The UPC bar code used on merchandise labels in supermarkets consists of a guard pattern 101, an industry code character, 5 data characters, a centre pattern 01010, 5 data characters, a check character and a guard pattern 101. Equal-width black bars and white spaces are used for 1 and 0 respectively, and each character has 7 bits in a code such that (given that adjacent bars /spaces are contiguous) each character has two variable-width bars and two variable-width spaces. The code used to the right of the centre pattern has black and white interchanged relative to the code used to the left (so the left and right have odd and even parity respectively, which permits discrimination of direction of reading). In Fig. 8, the electric signal representing the scanned code is applied at a (top left) via G1, G2, G3 to a shift register 9, a bit clock for shifting the signals in being derived as follows. During the 10 of the first guard pattern, a gate G5 passes clock pulses from an oscillator 1 via a dividefrequency-by-4 circuit 2 to a counter 3. During the first character, FF3 is set to enable G6 to pass clock pulses from oscillator 1 to a counter 4 and whenever this is equal to counter 3, a comparator 5 resets counter 4 and switches FF4 (which acts as a divide-frequency-by-2 circuit). FF4 provides the bit clock for shift register 9. The bit clock pulses are counted at 8, a count of 7 resetting FF3 (end of character). Oscillator 1 also drives a counter 7 via a divide-frequencyby-14 circuit 6, counter 7 being reset at the end of the guard pattern and at the end of each character. At the end of each character (before resetting), the contents of counter 7 are loaded into counter 3 (which now acts as a store, merely) and compared with counter 4 as before to provide the bit clock for register 9 (for the next character) &c. Each character is provided in parallel from register 9 to a buffer to feed a computer, with a strobe pulse at A10. The centre pattern is recognized at G13 to produce a pulse at A1 and invert subsequent bits at G1. A parity check is performed on each character at 15. Monostable 12 detects absence of input at a to reset the circuitry, reset also occurring at power-on.
