Abstract: 1,247,841. Endless and roller conveyers. CRISPLANT A/S. 23 Sept., 1968 [25 Aug., 1967], No. 39175/67. Heading B8A. Parcels 36 and the like are temporarily stopped by a raisable stop 24 at one of a pair of receiving stations 4, 6, comprised of a plurality of rollers 10 driven by an endless belt 14, whereat the parcel's destination is read by an operator who feeds a corresponding code into a control box 40 connected to a memory device (56), Fig. 2 (not shown). The operator then presses a release button 46 on the control box 40 which initiates the lowering of the stop 24 provided that a parcel is not at that instant leaving the other receiving station and provided that a set time delay has elapsed since the release of the last parcel, irrespective of the station, thereby ensuring an even spacing of the parcels downstream of the station. On release of the parcel by the stop 24 the parcel interrupts a plate-electric cell 32, 34 which prevents the said lowering of the stop in the other receiving station and initiates the raising of the respective stop 24 on passage of the trailing edge of the parcel and in conjunction with a pulser (70) measures the length of the parcel. The pair of receiving stations feed a common conveyer 16 constituted by further rollers 18 driven by an endless belt 20 at a greater velocity than the rollers 10 and having an anti-slip coating whereby to assist in the rapid removal of the articles from the area of the stop. The conveyer 16 has a converging path the edges of which are defined by a pair of endless belts 38 driven at a velocity such that their component of velocity in the direction of conveyance is equal to that of the rollers 20. The parcels are subsequently fed to a further roller conveyer 22 for conveyance to their desired destination whereat the respective code in the memory actuates a discharge device, which may comprise a dead or live arm or means for tilting the rollers. The number of rollers that are tilted depending on the length of the article as measured by the photo-electric cell 32, 34. Sequential operation of the above is through a control circuit (Fig. 2 and 3, not shown), whereby the receiving stations may alternately feed the conveyer 16 or one receiving station may have preference over the other. The roller conveyers may be replaced by endless conveyers.

Title: Separating diacetylene from acetone by distillation
IPC: C07C7/11
Filed: 1956-12-28
Abstract: Diacetylene is separated from a mixture with acetone by heating the mixture to form a vapour, contacting the vapour with water to dissolve substantially all the acetone vapours, and cooling and condensing the diacetylene vapours, preferably directly into a solution of not more than 20 per cent concentration in a solvent. The water used is preferably cooled to 10 DEG  to 25 DEG  C. and the solvent to between -40 DEG  and 10 DEG  C.  In an example a solution containing 8.3 per weight of diacetylene together with benzene and vinyl acetylene in acetone is changed to a kettle surmounted by a packed glass fractionating column fitted with a dephlegmator.  Water is fed into the dephlegmator head and flows down the column. Diethylene glycol diethyl ether is used as a collecting solvent and the diacetylene recovery is 85 per cent. Other suitable solvents mentioned are alkyl alcohols, e.g. methanol, ethanol, butanol, 2-ethyl butanol and diethyl carbitol; glycols, e.g. ethylene glycol, ethers, esters, ketones and chlorinated hydrocarbons, e.g. carbon tetrachloride.

Title: Method of determining exposure amounts in photographic printing
IPC: G03B27/73
Filed: 1973-08-21
Abstract: 1448225 Exposure control in photographic printers KONISHIROKU PHOTO INDUSTRY CO Ltd 21 Aug 1973 [25 Aug 1972] 39665/73 Heading G2A Optical characteristics including large area transmittance density of negatives on a film strip to be printed are measured to determine provisional exposure conditions for each negative and whenever two (or three) adjacent negatives have large area transmittance densities differing by less than a predetermined amount their exposure conditions are averaged. This is to ensure that when the strip contains a number of photographs of the same scene, the prints of the scene will not differ from each other; which they may do if the exposure conditions are determined solely on the basis of individual analysis. As shown, a strip 1 is fed past stations 3, 8 and 10 which respectively determine the base density, size, and type (i.e. manufacturer) of each negative and feed corresponding values to a circuit 14 which sends an appropriate first correction factor to an operation circuit 17. At station 6 light is directed through the strip 1 and is directed (a) to an integrating sphere 20 having photomultipliers 22 respectively located behind red, green and blue filters to measure the large area transmittance density of the three colour components (b) to an integrating sphere 20 having a similar photo-multiplier arrangement 22' to measure the colour transmittance densities in the central portion only of each negative and (c) through optical fibre bundles 27 to photo-multipliers 28 to measure the neutral density of each negative in various areas. The outputs of the photo-multipliers are fed through an A-D converter to circuit 17, which selects a corresponding second connection factor. The factors are fed from circuit 17 to a circuit 25 which determines provisional exposure factors, compares large area transmittance densities and, when the densities of adjacent negatives have large area transmittance densities differing by less than 0À1 averages the provisional factors for those negatives. Final values are retained in a store 33. In determining provisional exposure factors, if a negative has abnormal colour characteristics circuit 25 has to determine whether this is due to a charge of light source or to a subjective colour density failure. In cases where this is difficult to decide, circuit 25 compares the colour characteristics of the frame in question with those of the preceding and succeeding frames. When the characteristics are the same it is assumed that the light source was changed; when they differ it is assumed that the negative is a subjective colour density failure. An indicator 31 indicates the number of tested frames and correction values.

Abstract: 1357857 Radio signalling; inductive signalling INTERNATIONAL STANDARD ELECTRIC CORP 30 Aug 1972 [6 Sept 1971] 40152/72 Headings H4L and H4U A radio paging system for calling mobile subscribers, includes a relay station which receives coded calling signals from a central transmitter and retransmits only those calls whose codes correspond to a selected subscriber or subscribers. As described, a nationwide system includes a central transmitter whose calls are retransmitted by a number of regional transmitters and the present arrangement enables the mobile subscribers with portable receivers to receive calls from the central radio transmitter which may be at a considerable distance away. The retransmission may be on a frequency identical to that of the central transmitter, may be shifted up or down by 4KHZ, or may be selected from a number of frequencies allotted to the retransmission service Alternatively the retransmission may be via an inductive loop. A transceiver mounted in a vehicle and forming a part of a mobile network may be adapted to effect the retransmission and to convert the received coded signals into more simple codes as used in the mobile network. In one arrangement, Fig. 1, the coded signals received by the repeater is demodulated at 2 and the signals decoded at 3 are supplied to a timer 7. A register 6 receives the output of receiver 2 and delivers stored code signals to a transmitter 8 when a control signal is received from the timer 7.

Title: Rotating pistons for reciprocating internal combustion engines
IPC: F16J1/24
Filed: 1963-10-14
Abstract: 978,923. Pistons. SULZER BROS. Ltd. Oct. 14, 1963 [Nov. 9, 1962], No. 40491/63. Heading F2T. A rotatable piston for a reciprocating I.C. engine comprises a mass arranged to be moved in the same axial direction as the piston, means being provided for converting the inertia forces produced on the mass by reciprocation of the piston into a torque which tends to rotate the piston. In the embodiment shown in Fig. 1, the mass 15 is screw-threaded on to a spindle 14 disposed inside a chamber 16 inside the piston which is filled with oil from the lubricating system for cooling via bores 20, 19, 21 and drained via bore 22 and constriction 23. When the piston is reciprocated, the screw-threads convert the axial movement of the mass into a rotary one with consequent rotation of the piston. Rotation of the piston is effective in only one direction owing to (a) the difference in friction between the compression and expansion strokes of the piston and (b) a greater reaction occurring when the mass is moved downwardly through the oil, this reaction being greater because of easy escape of oil under projections 24 on the bottom of the mass resulting in a rapid retardation of the mass; slow retardation of the mass occurs during upward movement of the mass because of the cushioning effect of the mass as it enters a recess 25 in the piston. In the embodiment shown in Fig. 2, the mass 48 is mounted on a pin 50 and provided with helical ribs 54. When the mass is moved along the pin, the ribs cause rotation of the mass, the reaction forces being operative through the oil in the chamber 47 and ribs 53 on the piston to cause rotation of the latter. In the embodiment shown in Fig. 3, the mass 65 acts like a piston within a recess 63 to suck oil through bores 66, 67 and valves 68, 70 and discharge it as jets through bores 71, 72 and valves 75, 76, the reaction of the jets causing rotation of the piston. A further embodiment, Fig. 5, shows the mass mounted on a pair of pivot-arms and arranged, when moved up and down by the piston, to rotate bevel wheels 135 through unidirectional clutches and thereby cause rotation of the gear ring 136 and piston; hammering of the mass can be reduced by filling the chamber containing the mass with oil and providing cushioning recesses or by the use of resilient abutments. The invention may also be applied to free piston engines.

Abstract: 960,387. Counting. PHILCO CORPORATION. Nov. 25, 1960 [Nov. 25, 1959], No. 40567/60. Heading G4A. [Also in Division H3] A multistable state circuit comprises a number of serially connected tunnel diodes 12, 13, 14 and means for applying pulses to establish a series of voltage stable states in the diodes. In a counter circuit, Fig. 4, the diodes are biased to their operating point by current source 15 and input pulses are applied from pulse source 16 to switch the diodes in turn from a low voltage state to a high one. When all diodes are in their high voltage state, transistor 28 conducts producing an output pulse, and also producing a pulse via transformer 27 which saturates transistor 25, thus short-circuiting the tunnel diodes to reset them to their low voltage state. Transistor 28 is thus again cut off to terminate the output pulse. In an alternative embodiment, Fig. 5, fast acting diodes are used in place of the transistors. The voltage across the tunnel diodes causes a fast acting diode 41 to conduct thus diverting some current from the tunnel diode path. This current flows through winding 42 of transformer 39 to produce an output pulse, and also produces a voltage across winding 38 which opposes the conduction of the tunnel diodes to reduce the current still further until the counter restores to its original state. Diode 41 then ceases to conduct, terminating the output pulse. A further diode 40 is connected across winding 38 to prevent undesired current flow in the tunnel diodes at the time of reversal of the voltage across winding 38.

In a servo mechanism for controlling movement comprising command means for producing pulses representing the desired movement and feedback means producing pulses indicating movement, there is a pulse generator 70, Fig. 1, producing first and second pulse trains displaced by 80 degrees which are applied to the command means to produce forward or backward command signals, X+, X - as the case may be, having one or the other of the two clock signal phases, and to the movement transducer 91 to produce similar forward or backward signals W+, W-, the command and feedback signals being compared in a comparator 80 comprising two similar counters 10, 20, Fig. 2, one receiving clock pulses and the other receiving the same clock pulses modified by the addition of extra pulses for each increment of the command movement or decrement of the feed-back movement and by the subtraction of pulses for each decrement of the command movement or increment of the feed-back movement, the output member being driven under the control of the values of the two counters until balance is reached, the values then being equal. The outputs of the counters 10, 20 are applied to set and reset flip-flops 30 which, according to the values, in the counters spends a greater or lesser period of each cycle in one state than the other. Phase discriminator 100 produces an analogue signal representing the mean of the output from the flip-flop. When balance is achieved the flip-flop spends half of each cycle in each of the two states and the mean output is zero so that the motor stops. More than one operational counter 20 can be associated with a single reference counter 10.
