Patent GB-1189895-A (GB)
Title: Switching Apparatus
IPC: G05B19/08
Filed: 1968-08-26
Abstract: 1,189,895. Switching circuits. KRAUSS-MAFFEI A.G. 26 Aug., 1968 [3 Oct., 1967], No. 40612/68. Heading G4H. In a switching arrangement for machine control systems, the operational steps of the machine are controlled by predetermined combinations of input switches 1-5, the closure of a given combination of switches (e.g. 1, 3 and 5) causing a resistor array 120 to apply a zero current signal to one of a number of transistor amplifiers (e.g. 18) to set a corresponding multivibrator (e.g. 42). The output from the multivibrator 42 is connected in another resistor array 121 to operate associated ones of relays 6-10. The switches 1-5 may be manually operated, or operated by the movements of the machine. Switch 5 is a magnetically operated transistor (Fig. 4, not shown). The switches are connected to column wires 30-34 and these are connected by resistors 41 to row wires 35-40. The column wires are connected to the positive pole via resistors 11-15 so that when the switches are open current can pass to the amplifiers 18-23. When all the switches connected to a row wire are closed there is no signal and the corresponding multivibrator operates. Multivibrator 43 is connected to two row wires and is therefore operated by two different combinations of switches 1-5 (1 and 4, 1 and 2). There is also a feedback line 59 from multivibrator 42 so that unless this has first been operated the multivibrator 43 cannot be operated. Similarly multivibrator 44 responds to three different combinations if multivibrator 43 has already been operated. The outputs leads 45-47 from the multivibrators are connected via resistors 48 to combinations of relays 6-10. The relays may also be controlled by switches 63, 64. The relays, which may be transistor circuits or thyristors, control the operating steps of the machine. The resistor circuits 120, 121 may be formed by providing parallel row conductors on one side of an insulating plate and the column conductors on the other, the resistors being soldered to the conductors through holes in the plate.

Title: Improvements in sheet feeding devices
IPC: G06K13/077
Filed: 1958-12-17
Abstract: 882,218. Punching sheets. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 17, 1958 [Dec. 23, 1957], No. 40740/58. Class 31 (2). [Also in Group XVI] Record cards 10, prior to feeding to a punching station, are separated sequentially from a stack by a feed-knife or other known means 15 and fed by rollers 16, 17 to rollers 21, 22, driven by a motor 20 which feed the cards on to a pair of timing conveyer belts 31 provided with pairs of stop projections 32 which frame each card. A pair of friction belts 33, driven by a motor 39, co-operate with the timing belts 31 to urge the cards towards the stop projections 32 and, subsequently, into contact with a movable stop 41 which registers each card at a punching station 13. The timing belts 31 are driven intermittently by a means 30, which may be an hydraulic drive mechanism, such that cards 10, which are received at a constant speed from the feed rollers 21, 22, are accelerated by the belts 31 to a maximum speed and then retarded so that they are brought to rest at the punching station 13. The friction belts 33 are driven at a constant speed which is slightly higher than the maximum speed of the timing belts 33. The projections 32 on the timing belts are in pairs 32a, 32b which are spaced apart to frame a card 10 with about one-eighth of an inch clearance, and of a height equal to the thickness of a card if they extend across the width of the belts 31. The register stop comprises a transverse bar 41 on a rod 42 secured at each end to a double-armed pivoted lever 43 adapted to be rocked, against the action of a spring 44, by an hydraulic piston to cause the bar to move away from the path of the cards 10. The levers 43 could be operated by cams. In operation, as the leading edge of a card 10 approaches the bite of the belts 31, 33, the accelerated belts 31 have obtained the speed of the card, and the latter is just clear of the front and rear projections 32a, 32b on the belts. The belts 33 now cause the front edge of the card to abut the front projection 32a, the belts 31 are accelerated and then retarded to rest position, and the belts 33 move the card to abut the register bar 41 at the punching station 13. After the punching operation, the register bar 41 is swung away, and the card is fed by the grip of the belts and the rear projection 32b on the belts 31 to a second punching station 14 and second register bar 41, and it is then delivered to a stacking means.

Title: Electrical measuring apparatus
IPC: H03K5/26
Filed: 1975-10-07
Abstract: 1519218 Automatic phase control; digital phase measurement INTERNATIONAL BUSINESS MACHINES CORP 7 Oct 1975 [30 Dec 1974] 40912/75 Headings H3A and H3H Phase differences between a signal from an unknown source Sx and a reference signal SR are measured by clock signals from a phase-locked loop which are gated to a counter by a circuit which enables the gate 19 in response to the reference signal SR and disables it in response to the unknown signal Sx. The resultant count is a measure of the phase difference. Accuracy and stability derive from maintenance of a predetermined phase locking between a signal derived by frequency division of the loop output signal and the reference signal, the loop output signal being a harmonic of the reference signal. Increased capture range is achieved by using two identical frequency dividers 27A, 27B in the phase locked loop.

Abstract: 1,223,534. Acoustic delay lines. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 Aug., 1969 [22 Aug., 1968], No. 41371/69. Heading H3U. To eliminate unwanted second or third time reflection signals in a delay device comprising a glass body 1 having input and output piezoelectric transducers 2, 3, a stepped reflecting surface 4, 5 is provided. The step is positioned so that one half of the waves from input 2 are reflected from the surface 4 to the output 3 and the other half are reflected from the surface 5 to the output. The difference in travel time of the two paths is chosen so that the desired signal is attenuated only slightly whereas the undesired reflection component is considerably suppressed since the reflection signals arrive in phase opposition to each other at the output transducer 3.

Abstract: 1,175,567. Automatic temperature control systems. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. Sept.12, 1967 [Sept. 12, 1966], No. 41491/67, Heading G3R. [Also in Division G1] The surface of the charge (2) in the shaft (1) of a blast furnace is scanned by a television camera (3) and information as to the intensity of light emitted from points on this surface (indicative of the temperature of each point) and as to the position of each point, transmitted to a computer. The output of the computer is fed through a digital converter to a display screen, which provides a numerical zonal display of the temperatures in the various areas on the surface of the charge (2). The intensity (temperature) values may be compensated for the differences in the distances of the respective points from the camera by modifying the values using information from a conventional telemetering system. Alternatively, a movable T.V. camera is used for both the temperature and telemetering measurements, Fig. 4 (not shown). The surface of the charge may for example be considered as being a number of concentric zones subdivided into sectors and an average value of the temperature of the points in each sector is taken. The average value for the different zones is then compared with the average temperature for the whole surface and any difference results in the addition of either more coke or more ore to the melt at a particular sector to raise or lower the temperature of that sector to the average value of the whole surface. There may be a plurality of T.V. cameras to allow viewing of the whole surface if this is too large to be covered by a single camera. Alternatively a single orientable camera may be moved to view successively all parts of the surface.
