Title: Improvements relating to methods and apparatus for producing stockings
Inventor: PALME OTTO
IPC: D04B9/06
Filed: 1968-09-04
Abstract: 1,236,256. Knitting-machines. O. PALME and F. VATTER [trading as J. H. VATTER NACHF. K.G.] 4 Sept., 1968 [18 Sept., 1967], No. 42062/68. Headings D1C and D1K. The diol cam system at each head of a cylinder and dial machine includes a bolt knitting cam insertable in advance of the usual knitting cam. The cam is depressed to chosen levels by a pattern controlled lever. The system enables dial needles to knock over in advance of cylinder needles and avoid taking yarn fed to the latter. If yarn is fed behind the cylinder needles to those of the dial, two plies will be knitted. A two ply stocking welt may be knitted in this way; the two plies being joined at either end by rib knitting. The plies may be joined in certain wales by low butt needles which raise the bolt cam. The heel area may be rib knit to facilitate shaping by ensuring that the dial needles of the surrounding areas are retracted by the bolt cam to raise the yarn. The sole may be ribbed and include and additional, cotton, yarn.

Title: Fuel injection pumps
IPC: F02M41/12
Filed: 1971-09-09
Abstract: 1369818 Fuel injection pumps ROBERT BOSCH GmbH 9 Sept 1971 [10 Sept 1970] 42063/71 Heading F1A In a fuel injection pump wherein the delivery from a pumping chamber 4 is controlled by a spring-loaded spool valve 14 in a by-pass passage 16a, 16b and reciprocable by the alternate flow of fuel into and out of a pressure chamber 39, the out flow being controlled by adjustable throttles 31, 35 to provide a hydraulic lock at a given speed, the valve 14 is rotatable to a position for starting in which its forward stroke is delayed to prevent opening of the by-pass 16a, 16b at low speeds, but at higher speeds the by-pass is arranged to open after a smaller displacement than with the valve in its normal operating position. Thus in the starting position shown, fuel displaced by an auxiliary pumping piston 18 enters the pressure chamber 39 and initially flows to an overflow passage 32 by way of a groove 40 in the spool valve 14. As the speed increases the spool valve moves to first throttle and then closes the groove 40. Further speed increase results in hydraulic lock occurring in dependence on the axial position of a spool valve 28 controlling in inverse ratio the size of the throttles 31, 35 in return passages 25, 34. Because of the inclined control edge 44 on the valve spool 14 the by-pass 16a, 16b is opened earlier than if, for the same high speed, the valve is rotated to its normal position in which the groove 40 and overflow passage 32 are disconnected.  In a modification the lower end of the spool valve 14 is provided with a projecting segment (46) and the end of the passage 34 controlled by the spool valve 14 is extended in a circumferential direction. This modification prevents unstable operation occurring in the event of the spool valve being moved to its starting position during normal low speed operation.

Title: Improvements in and relating to the application of protective and insulating coatings on metals
Inventor: SIMONS JOHN SPENCER
IPC: H01B3/30
Filed: 1960-12-12
Abstract: An electrical conductor is provided with an adherent protective and electrically insulating coating, said coating comprising a thermosetting resin reinforced with a refractory insulating material of a higher dielectric strength than the resin, and in the form of micro-crystalline flakes, the flakes of the said material being arranged in planes lying substantially parallel to the surface of the said conductor.  The preferred resin is an epoxy resin and the preferred refractory insulating material is mica.  The powdered resin and the flakes of refractory insulating material may be introduced into a closed chamber within which an electrostatic field is established, and the metal parts to be coated then introduced into this chamber.  The conductor may then be heated for example by passing an electric current through it to cause the coating to coalesce. Alternatively, the resin and the refractory material may be applied in the form of alternate layers by the electrostatic method. The resin alone may be deposited by dip-coating or by the fluidized bed process.  The metal parts may be pretreated with an epoxy resin varnish prior to the application of the insulating coating.  Portions of the metal surface not required to be coated may be protected by a mask.  To produce a metal member comprising an assembly of separate conductors, the individual conductors are initially coated by the electrostatic process described, the whole p  assembly being subsequently reheated to allow the individual coatings to coalesce; a further coating may then be applied to the composite unit.

Abstract: 1,179,309. Analogue/digital converter. VARIAN ASSOCIATES. 22 Sept., 1967 [28 Sept., 1966], No. 43311/67. Heading G4H. [Also in Division G1] In an electrographic recorder with an electronic analogue-to-digital converter arranged to convert a variable signal Ei applied to terminals 2 into digital form in order selectively to apply writing potential to electrodes 9 in an array across recording medium 11 and so to record the variable thereon, the converter includes a pulse generator 4, an electronic counter circuit for producing a reference signal Er whose amplitude is proportional to the number of pulses counted, means 3 comparing the signals Ei, Er to produce an error signal Ee which shuts off pulses from the generator 4 at zero error so that the count stops at a null balance count and electronic gates responsive to the null balance count selectively to apply writing potential to the electrodes 9. As shown in Fig. 1, the counter is a bidirectional shift register 7 with an array of flip-flops 6, of which one, 6<SP>1</SP>, has initially an output opposite to all the others and this opposite output can be made to travel round the ring a step for each pulse. The outputs of the flip-flops 6 are tied through diodes 13 to successively higher resistance points of a resistor 14 to produce successive values of Er and are also applied to gates 8. The gates 8 include transistors which take longer to switch than the flip-flops 6 so that only when the register 7 dwells on a null balance count can a transistor be biased to the conductive state and the gate 8 allow sufficient potential to pass between the corresponding electrode 9 and a common electrode 12 for writing on the intervening medium 11. A commutator, Fig. 5 (not shown), may be used to allow time sharing between several variables. Alternative counting and selecting circuits providing analogue-to-digital conversion are described with reference to Figs. 3 and 4 (not shown).

Abstract: 1427898 Profiling opthalmic lens edges, workpiece clamping ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE) 9 Oct 1974 [9 Oct 1973] 43752/74 Headings B3B and B3T In a machine tool for profiling the edge surfaces of opthalmic lenses a template of the lens edge profile and the lens to be machined are secured coaxially one at each end respectively of the machine spindle by respective clamping jaws actuated by a common actuating means. In the embodiment described the machine is provided with a driven work spindle 3 rotatably supported in a machine frame and a clamping jaw 1, 2 coaxial with the spindle and located adjacent each end of the spindle respectively. The jaws 1, 2, are connected to respective rack members 5, 6 engaged by a common pinion 8 which is supported on a slide 9 movable parallel to the spindle axis, the racks also being movable in directions parallel to the spindle and to the slide 9. A handle 12 is secured to the pinion 8 to control the movement of the racks and hence the jaws 1, 2. In the inoperative position, the jaw 1 is urged into abutment with its respective end of the spindle by a spring 14 and the other jaw 2 is spaced from the other end of the spindle with a stop 13 at the end of rack 6 engaging an abutment on the machine frame 7. The lever 12 is then pivoted in a clockwise direction causing the pinion 8 to roll on the rack 6 by displacement of the slide 9 at the same time displacing the rack 5 to the left to move the jaw 1 away from its end of the spindle, thus allowing a template 15 to be placed between the jaw 1 and the end of the spindle 3. By releasing the control lever the rack and jaw 1 are then returned to their initial position by way of the spring 14 but with the template securely held between the jaw 1 and end of the spindle. Likewise the workpiece or lens 16 is then located between the jaw 2 and its ends of the spindle and clamped between the jaw 2 and spindle by rotating the lever in an anticlockwise direction which causes the pinion 8 to roll on the rack 5 and hence move the rack 6 to the left by way of the slide 9 which also moves to the left. The interaction of the two racks 5 and 6 causes the template and workpiece or lens to be held simultaneously by jaws 1, 2 at each end of the spindle respectively. In this arrangement the resultant axial force on the spindle by the jaws 1 is zero and hence the spindle is not subjected to any axial thrust during the profiling operation.
