The tuning condenser 2, Fig. 1, of a radio receiver is mounted on a U-shaped bracket 1 which forms the bearings for an epicyclic drive. Condenser 2 is driven by means of gears 3, 4, of which the latter is attached to a hollow shaft 5. Shaft 5 carries the fast speed knob 8 and pulley 7 which drives the pointer 18 via cord 17. Within shaft 5 is a second shaft 10 which carries the slow speed knob 11; the epicyclic drive is constituted by balls 14, Fig. 3, which lie in apertures 13 in the shaft 5 and engage a groove 20 in the shaft 10 and the surface of a bore in limb 6 of member 1. The groove 20 may be elliptic in shape or of greater diameter than the balls 14 and the knob 11 urged away from knob 8 by means of a spring 21. The diameter of the bore in member 6 is such that the balls 14 do not normally engage both it and shaft 10: in this case, in order to obtain a slow speed drive knob 11 is pressed in so that the balls engage both the bore and the shaft.

Abstract: 978,120. Distillation apparatus; separating fractions of a liquid mixture for chemical analysis. TECHNICON INSTRUMENTS CORPORATION. Nov. 5, 1962 [Nov. 13, 1961], No. 41672/62. Heading B1B. Liquid to be distilled is fed through tube 90 into the end of a helical passage 14 formed along the inner surface of a horizontal cylindrical vessel 12 which is rotated about its longitudinal axis on rollers 24. The lower portion of the vessel is heated by electrical heater 20. Discrete elements of the liquid pass along the vessel in the lowest sections of the helical passage. The vapours evolved from the heated liquid are drawn into tube 56 through holes 60, and then flow through line 65 into condenser 64, by the action of a vacuum pump connected to the outlet 79 of the condenser. The condensate collects in receptacle 80. The residual undistilled liquid reaching the left-hand end of vessel 12 discharges into outlet cap 44, and leaves the apparatus through outlet 52. For the separation of a liquid mixture, a number of separate vapour tubes 62, Fig. 3, are located within the tube 56, each tube 62 being connected to one of the holes 60 in tube 56 and leading to a separate condenser. The components of the liquid mixture vaporize in sequence in vessel 12, and the vapour fractions are withdrawn via the separate tubes 62. The apparatus may be used for the separation of samples for chemical analysis, e.g. in the determination of the alcohol content of beer, or the phenol content of plant effluent. Specifications 774,711, 783,649 and 834,635 are referred to.

Abstract: 1378876 Picking-up tools; working semiconductors SONY CORP 7 Sept 1971 [8 Sept 1970 (2) 30 Oct 1970 5 Feb 1971] 41762/71 Headings B4W and B5E [Also in Divisions B3 and H1] A tool (Fig. 6A) for picking-up apertured semi-conductor wafers is formed from a hollow cylinder with a peripheral groove 52 adjacent one end by cutting two slots 48 from one end parallel to its axis. With the legs defined by the slots pinched together the grooved end of the tool is passed through the aperture in the wafer and the legs released so that the groove engages the walls of the aperture. The tool may have a loop at 54 for hanging on a hook. In a modification with only two slots the ends of the legs are tapered to engage the mating walls of a recess formed in a projection from a holder over which the wafer is to be dropped. The central bore of a rod from which the apertured wafer is sliced is cut ultrasonically. The cutter (Fig. 18) comprises a ferrite or magnetostrictive structure 118 producing longitudinal vibrations which are communicated to a cutting tip 121 shown more clearly in Fig. 19A, by a hollow stainless steel pipe, an odd number of half-wavelengths long, through which water mixed with carborundum is fed to the cutting tip. This tip, the dimensions of which are given, has a groove between two flanges generally of the same profile as the required hole but with angularly offset sets of grooves 131, 132 to allow polishing material entering the cutting area via holes 133 in the groove to escape. The forward end of the tip, which is apertured to leave a core centrally of the hole, is conical.

Filed: 1970-09-03
Abstract: 1311693 Non-woven net CHAVANOZ SA 3 Sept 1970 [11 Sept 1969] 42296/70 Heading D1R An apparatus for use in producing non- woven net fabric by winding a continuous thread around spaced elongate supports, and advancing the thread sections extending between the supports while maintaining the sections in spaced parallel positions to form a weft sheet, is characterised by having control means for sensing the presence of thread sections in the sheet, and for stopping the winding and advancing means in response to the absence of one or more sections from the sheet. Thread 32 is wound by rotating tube 20 about helical springs 36, 38 which rotate to advance the thread sections 5 to form the weft sheet. The control means includes a photoelectric cell 80 which, when it senses the presence of passing thread sections, emits a signal to reset a time switch set to stop the rotation of tube 20 and springs 36, 38. When the cell fails to emit a signal, due to the absence of a thread section from the weft sheet, the time switch operates to stop the rotation of the tube and springs. The springs may be replaced by other members having a helical configuration, e.g. screws, threaded cylinders or helically grooved cylinders. The cell may be replaced by, e.g. a fluidic pressure sensing device. The net fabric is formed by bonding warp threads to the weft threads. Selvage threads 74, 76 may be fed through the springs to lie within the loop ends of the thread sections.

Abstract: 1532251 Data processing HONEYWELL INFORMATION SYSTEMS Inc 20 Oct 1975 [21 Oct 1974 (2)] 42901/75 Heading G4A A multiprogrammed data processing system transfers from a first procedure to a second procedure, the transfer instruction specifying those program segments to which the second procedure should have access, by safestoring descriptors not accessible to the second procedure, loading an instruction segment register with the address of a required instruction segment and an instruction counter with the number of the next instruction, loading a parameter stack register if parameters are to be passed from the first procedure to the second procedure and adjusting the parameter stack register and an argument stack register to reflect the passage of parameters. The first procedure calls for the second procedure, the safestored descriptors being returned to the appropriate registers on completion of the second procedure. The descriptors define memory locations containing program segments and data files. Each procedure is also limited to assigned working space in a virtual memory of the system, as defined by the respective descriptors. Certain instructions cause, as a result of a call, no descriptors to be safestored, all the descriptors used by the first procedure being used by the second procedure, the second procedure possibly also using additional descriptors. To prevent access to certain portions of memory by the second procedure a "shrink" operation may be carried out on a descriptor so that the base and the size of the memory area as defined by the descriptor are altered so that the memory area defined by the altered description is smaller than the memory area defined by the descriptor prior to the "shrink" operation.

To this end the contacts 55, 57, 59, 61 of a direction switch 15, which applies gating signals to the thyristors through diodes 37, 41, 45, 49, 53 and resistors 35, 39, 43, 47, 51, are arranged to be operated in pairs 55, 59 and 57, 61 so that they are all open for a period between transition from one contact pair to the other. Thyristor 17 is conductive during normal running of the motor and circulates flyback current through the motor field and armature and the relevant thyristor pair 19, 27 or 21, 23 during off periods of the chopper 33. During operation of the switch 15, both contacts 59, 61 are simultaneously open to cause the thyristor 17 to turn off and so interrupt the flyback current to allow the conducting thyristor pair 19, 27 or 21, 23 to turn off. Closure of contact 55 or 57 makes conductive the appropriate pair of thyristors and closure of contact 59 or 61 fires the thyristor 17 to allow the induced current from the armature 31 to be applied through the conducting thyristor pair to the field winding 25 to reverse the motor direction. Diode 29 acts as a "plugging" diode to conduct the induced armature current after the motor connections are reversed and while it is still rotating in the original direction. The thyristors may be replaced by the combination of a PNP and a NPN transistor interconnected to form a regenerative feedback pair,
