Title: A data transmission arrangement utilising phase shift carrier signalling
IPC: H04L27/227
Filed: 1961-02-23
Abstract: 964,176. Telegraphy. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 23, 1961 [Feb. 23, 1960], No. 6765/61. Heading H4P. In a carrier phase reversal signalling system the receiver has two phase detectors, one 10 for detecting the incoming signal phase reversals, the other 16 for comparing a local ambiguous phase reference signal, derived, e.g. by full-wave rectifying at 12 the incoming signals and then dividing by two at 14 the doubled frequency, with an incoming phase reference signal transmitted before the start of a message to derive a control potential which, dependent on its polarity, operates through a bi-stable circuit 18 to actuate or not a phase inverter switch 19 in one input to the main phase detector 10 so that ambiguity is removed. Since the " start " phase reference signal is in phase quadrature with the data signals a 90 degrees phase shifter 15 is inserted between the local phase reference generator 14 and the ambiguity resolving phase detector 16. The output of the latter may be rectified at 21 and applied to block a normally open gate 23 preceding the local phase reference generator 14 so that this generator is not influenced during the very short start signal by phase quadrature oscillations. The switch 19 may be in the other input to the detector 10. In a modification the " start " signal is a frequency shift detected by a frequency discriminator with output applied through a monostable circuit and " AND " gate circuit to the bi-stable circuit 18, the other input to the AND gate being taken from an output of phase detector 10 corresponding to a MARK signal which is always arranged to follow the " start " signal. The bi-stable circuit operating the phase inverter switch is then only actuated when the two inputs to the AND gate have a predetermined relative polarity. The filter 13 can be replaced by an oscillator with phase controlled by the output of rectifier 12.

Title: Hydraulic control system with automatic stop
IPC: F15B9/12
Filed: 1951-03-27
Abstract: 683,996. Hydraulic machines. BENDIX AVIATION CORPORATION. March 27, 1951 [March 27, 1950], No. 7137/51. Class 69 (ii). In a hydraulic control system comprising a motor, valve, and a control handle each having a movable element, the three elements are coupled together differentially so that motion of any element applies forces to the other elements to move that one of the other two elements offering the least resistance to motion. The motor 10 comprises a cylinder pivotally mounted at 18 and a piston 14 having a rod 15 connected to an arm 16 which extends to the device to be actuated. Fluid is supplied to the motor via conduits 21, 22 through a valve 11 having a grooved piston 27 held in the neutral position shown in Fig. 1 by a spring 29, in which position ports 19 and 20 leading to the conduits 21, 22 are blocked and ports 26 and 23 are connected and hence fluid supplied by a pump 12 flows via these latter ports and a conduit 24 back to the reservoir 25. The differential mechanism comprises a lever arm 42 pivotally connected to the piston rod 15 and by links 43 and 44 to the valve piston 27 and handle 13 respectively. To move the piston 14 to the right a predetermined distance corresponding to the setting of an adjustable stop 47, the handle 13 is given a push to the right and released. This movement shifts the valve piston 27 to the left where it is held by a garter spring 36 engaging a groove 40. Fluid flows via port 26, passage 30, port 19 and conduit 21 to move the piston 14 to the right, the displaced fluid flowing via conduit 22, ports 20 and 23 and conduit 24 to the reservoir 25. As the valve piston 27 is held by the spring 36, movement of the rod 15 rotates the arm 42 clockwise about the link 43 and moves the handle 13 to the right in synchronism with the piston 14 until the handle is held by the stop 47. The arm 42 then rotates about the lefthand pivot of the link 44, the valve piston being moved to the right to force the spring 36 out of the groove 40 so that the spring 29 returns the piston 27 to its neutral position wherein further movement of the piston 14 is arrested. Similarly the piston 14 may be moved a predetermined distance to the left by pushing the handle 13 to a stop 48 to cause the spring 36 to engage a groove 41. The valve 11 contains a relief valve 35. Either or both of the stops 47 and 48 may be omitted and the handle 13 moved continuously by hand to a desired position corresponding to that to which it is desired to move the piston 14.

Filed: 1935-03-08
Abstract: 449,204. Conditioning air. ANDREW, T., Rivlyn, Davenport Park, and HOLT, S., The Oaklands, Offerton Lane, both in Stockport, Cheshire. March 8, 1935, No. 7282. Addition to 428,319. [Class 137] In apparatus for controlling the humidity and temperature of air, of the kind described in the parent Specification in which a thermostat controls the water supply to air sprayers in a main air supply and the temperature of such supply and in which a hygrostat in each branch air supply causes the operation of an air heater in cases of high humidity, one of said hygrostats acting as a master hygrostat to control the sprayers, a thermostat and a hygrostat are employed in each branch to control the air heating means, the hygrostat also regulating the flow of air through the branch. The air is circulated through a main trunk (not shown), to four branch ducts (not shown), each having a thermostat a and hygrostat b located in the room concerned. If the temperature falls, the thermostat a admits air to the part d<3> of the compressed air control line d, and if the humidity rises, the hygrostat b admits air to a part d<1> of the control line, the air pressure in either of these opening valve c and admitting steam to heater g. Increase of pressure in line d<1> also operates a motor e to close louvres f, thus reducing the air delivered by the branch and increasing the temperature of the air and reducing the relative humidity in the room. One of the hygrostats b acts as a master hygrostat, and may cause a switch i to start a pump j supplying water to sprays m in the main air trunk, simultaneously a steam valve k may be operated to supply steam to and heat water passing to the sprays m. An additional steam valve l, hydraulically operated by the water pressure from the pump j prevents the admission of steam until the sprays m are in operation. A thermostat q at the entrance to the main trunk actuates a motor r to close one set of louvres p for re-circulated air, and open another set o for fresh air to cause a fall of temperature. A compressed air plant n supplies air under pressure for the various controls. The valve k may be alternatively coupled to a dew-point thermostat s in the main trunk, cocks t and u permitting of the operation of the valve k either by the hygrostat b or by the thermostat s at choice. When the latter is used the thermostat q may be dispensed with.

Abstract: 1,262,891. Thermoelectric devices. WESTINGHOUSE ELECTRIC CORP. 11 Feb., 1969 [14 Feb., 1968], No. 7296/69. Heading H1K. A thermoelectric body 14 is disposed between two electrically conductive supports 12, 16 and is subjected to a compressive force by means of an insulating material which exhibits the property of shrinking on curing. As shown the pressure-applying insulating means comprises a thermosetting epoxy resin annulus 18 bonded to the supports 12, 16 by a bonding agent 20, which also seals a hole through the annulus 18 after curing to hermetically enclose the body 14. The body 14 may be soldered to the supports 12, 16, which may be of Cu, or may be held in place solely by the compressive forces. The annulus 18 may be an integral body, or may comprise two or more sections bonded together. It may be replaced by a moulded mass of a cold curing epoxy resin which shrinks on curing, or by two bars (52), Fig. 6 (not shown), of the thermosetting material bonded to the supports (12<SP>1</SP>, 16<SP>1</SP>) and urging them together due to shrinkage occurring during curing. The supports, or conductive plates bonded thereto, may serve as bridges between adjacent modules, heat transfer fins and ducts being provided in contact with the supports or plates. In a further modification each module comprises two complementary thermoelectric bodies (14), Fig. 9 (not shown), separated by a finned conductive unit (62), with each body (14) in contact with a respective one of the supports (68, 70) each of which carries further cooling fins. The compressive forces are applied through pairs of arms (78, 80) integral with or bonded to respective supports (68, 70), with the two arms of each pair directed towards one another but not meeting. A moulded mass (82) of an epoxy resin which shrinks on curing is bonded to the adjacent ends of the two arms (78, 80), and when cured this causes the ends of the arms to be drawn closer together, thus urging the supports (68, 70) towards one another and compressing the thermoelectric bodies (14). Two separate pairs of arms may be provided for each unit (62) of a series arrangement, or alternatively the arms may be common to all units (62).

Abstract: 671,377. Electric indicating systems. AIRMEC LABORATORIES, Ltd. Jan. 10, 1950. [March 17, 1949] No. 7365/49. Class 40 (i). [Also in Groups XIX and XL (b)] The total length in the direction of movement of a number of objects on a conveyer belt is measured by counting pulses generated at a speed proportional to that of the belt over the period during which the objects pass a fixed point. As shown, an object 3 on the belt interrupts a beam of light passing from a source 4 to a cell 6 through slotted masks 8, 11. A slotted disc 14 driven through gearing 32 from the belt driving shaft 12 interrupts a light beam to a photo cell 18 generating pulses which are fed to an amplifier 35. When the object interrupts the light to cell 6 an amplifier 25 operates a relay 22 connecting the amplifier 35 to an electronic pulse counter 20. The counter counts the pulses from cell 35 until the object has moved far enough to restore the beam to cell 6. A further counter 26 consisting of a number of decade units each comprising an index wheel operated by a high speed relay and a pawl and ratchet counts the number of objects on the belt. In a modification, a light spot is reflected from the belt to a photo-cell the amount of light to the cell being suddenly increased or decreased by the arrival of an object of contrasting colour. In a further modification the pulses may be generated by regularly spaced holes in the side of the belt passing a light beam intermittently to a cell on the other side of the belt.
