Abstract: 774,368. Electric cookers. GENERAL ELECTRIC CO. Dec. 2, 1955 [Dec. 2, 1954], No. 34573/55. Class 39(3) In an 'electric cooking appliance of the type comprising a well 2 disposed in an aperture in the horizontal top wall 1 of the cooker with an electric heater 8 movable in the well from the bottom thereof to the level of the top 1, the well is a cylindrical shell movable between a lower position in which the upper end 3 of the well is at the level of and rests on the top 1 and an upper position in which the bottom of the well is adjacent the aperture, and latch means 14 pivoted on brackets 13 on the underside of the hob 1 have abutment surfaces 16, 17 projecting through vertical slots 20 in the well, so that upward movement of the well raises the heater 8 to its upper position, and the surfaces 16, 17 of the latch engage brackets 19 on the heater 8 to retain it in its upper position when the well is returned to its lower position. In order to return the heater 8 to its lower position, the well 2 is raised above its normal upper position, whereby the latch 14 is released from the heater which returns with the well when the latter is lowered. The sheathed heater 8 has a drip pan 11 with a flange 10 resting in the lower position on bosses 6 in the shell 2, which has an external flange 3 normally resting on the top 1. The pivoted latch arm 14 is biased by a spring 15 to the position shown in Fig. 2 and has projecting fingers 16, 17, 18 adapted to extend into the slot 20. The fingers 16, 17 abut against the bracket 19 on the heater as shown in Fig. 5 to retain the heater in its upper position. To lower the heater, the well is raised until the bosses 6 lift the heater 8 from the latch 14, which is then moved by the spring 15 to the position shown in Fig. 2, whereby the heater returns with the well when pushed down to the lower position. Total removal of the well 2 is prevented by the engagement of fingers 18 with the lower end 22 of the slot, and further upward movement of the latch 14 is prevented by a stop element 13a on the bracket 13.

Title: Improvements relating to slur and carrier drive mechanisms for fully fashioned straight bar knitting machines
Inventor: WEST ERNEST
IPC: D04B15/64
Filed: 1968-07-20
Abstract: 1,207,761. Knitting machines. S. A. MONK (SUTTON-IN-ASHFIELD) Ltd. 16 July, 1969 [20 July, 1968], No. 34743/68. Heading D1C. In a multi-head straight bar knitting machine wherein the yarn carriers and slur cam tie bar reciprocate together an extra movement is imparted to the tie bar, at each reversal of the yarn carrier, to provide for a lead of the yarn carriers over the slur cams. A variable draw mechanism VDM reciprocates a rack 4 which rotates a shaft 6 having sprockets 9, 15 linearly moving chains 7, 14. Linear movement of the chain 14 reciprocates a roller 42 on a slide 43 having spring loaded plungers 54, 55 over which the idler may ride when the slide 43 and the yarn carrier YC connected to it, contacts stops 31, 32 on saddler 44, 45. Linear movement of the chain 7 rotates a shaft 11 having a pinion 10 reciprocating a rack 3 which drives the slur cam SC. The shaft 11 is mounted on a slipper 56 which is reciprocated on a rod 57 by a cam a linkage mechanism so that a linear movement is imparted to the shaft 11 rotating the pinion 10 and hence moving the slur cam SC, at the end of each stroke of the yarn carrier. The shaft 6 may have an overload mechanism and be driven by a pinion 5 and a driven plate 72 freely mounted on a hub 71 to the shaft 6. By way of balls 76 the plate 72 drives a plate 75 and drive plate 74 keyed to the hub 71 and pressed against the balls 76 by a spring 77. Upon overload the balls 76 move outwardly to disengage from recesses in the plates 72, 74 and the plate 74 is moved axially against the spring 77 to operate a micro switch 81 to stop the machine.

Abstract: 302,351. Siemens - Schuckertwerke Ges., (Assignees of Siemens-Schuckertwerke Akt.-Ges,). Dec. 15, 1927, [Convention date]. Addition to 226,547. Fluid.pressure.-The braking apparatus of the parent Specification is modified by providing means whereby the control valve of the pressure regulator 14 will be set for a value different from the usual full brake pressure when the safety brake is released. When the shaft 20 is turned on the occurrence of an emergency, the catches 22, 22<1> release the drop levers 37, 39, the former of which is connected by a rod 35 to the differential lever 28 pivoted to the end of the control valve spindle, and the latter of which is connected to the slide-valve 18. Consequently the rod 35 is moved until a stop 135 on it engages a lever 136 and the lever 28 is moved only to a position shown in dotted lines corresponding to reduced brake pressure. Since the lever 136 is connected to the rod 27, if the brake lever F is adjusted, it is moved towards the stop 135 and further restricts the movement of the rod 35 thereby ensuring that the brake pressure will not exceed the prescribed smaller value. The movement of the valve 18 disconnects the cylinder 9 from the pressure supply 16 and connects it to the exhaust 19. A throttle 119 in the exhaust is connected to the safety brake lever S in such a manner that when this lever is moved from the normal position 121 to the position 122, the throttle is opened and the weight 8 falls rapidly to apply the brake.

Title: Position determination
IPC: G03F9/00
Filed: 1975-08-22
Abstract: 1519469 Aligning semi-conductor wafers INTERNATIONAL BUSINESS MACHINES CORP 22 Aug 1975 [16 Sept 1974] 34887/75 Heading G1A To determine the position of an object such as a semi-conductor wafer with respect to an optical axis, the object is provided with a target having light scattering edges and a spot of light focused on to the object is caused to scan around the axis; the timing of the signals produced by a photodetector viewing the target indicates the amount and sense of misalignment of the target and the axis. In Fig. 1 a beam of light from laser 10 is deflected by a prism 12 and plate 13, and is then focused on object 19 by lens 17. The prism and plate are carried in a rotatable support 11 so that the focused light 21 can scan around axis 24, the angular position of the scan being found by an encoder 15. Object 19 is provided with a cruciform target 20, Fig. 2, and light is scattered from the target edges 23 into a collector, e.g. of optical fibres 18, Fig. 1, as the spot scans the target. Depending on the relative size of the spot and the cruciform legs, a photo-detector connected to the collector will produce one or two pulses for each leg scanned, Fig. 4 (not shown). By measuring the phase of these pulses the alignment of the cruciform and the axis is found. A similar measurement is also made at another target on the wafer to give accurate information about misalignment. The apparatus may be combined with similar apparatus for receiving light scattered through a mask, so that the relative alignment of a mask and a wafer can be controlled. Also, if the mask carries marks at positions corresponding to those on the wafer but rotated by 45 degrees, after exposure the mask marks will be superimposed on the wafer marks; if the superimposed marks (having eight arms) are scanned it is possible to verify whether the mask and wafer had been aligned during exposure, Fig. 5 (not shown).

Abstract: 784,112. Making heat exchangers from composite sheets. RIEPPEL, P. J., CLAPP, M. C., and EVANS, R. M. Dec. 6, 1955 [Dec. 9, 1954], No. 35004/55. Classes 83 (2) and 83 (4). A method of manufacturing a hollow metal structure, e.g. a heat exchanger, comprises inserting between dies a composite metal sheet containing at least one intermediate portion having a lower melting point than that of the outer portions and being capable of bonding under heat with said outer portions, heating said composite sheet to at least the melting point of the said intermediate portion but below the melting point of the outer portions, introducing into said intermediate portion, where the configuration of said dies permits, sufficient fluid pressure to expand said outer portions and allowing the resulting structure to cool whereby said outer portions are bonded to said intermediate portion in the unexpanded areas. The composite sheet 5 is prepared by jointing by rolling at about 700‹ F. two equal thicknesses of aluminium 6, 7 with an intermediate thickness of zinc 8. Prior to rolling, the sheets are degreased and wire brushed and the intermediate zinc sheet etched. To manufacture the heat exchanger shown in Fig. 4 the composite sheet 5 is placed between dies 9 and 10 and heated to about the melting point of the intermediate zinc layer whereupon a nipple 13 (Fig. 2) is inserted into the zinc layer. When the assembly reaches approximately 800‹ F. fluid pressure, e.g. nitrogen gas at 300 to 700 p.s.i., is introduced through the nipple 13 into the zinc layer to expand the outer layer 6 into the die recesses 11 and 12 (Fig. 3). To prevent sticking, the dies are treated with graphite, chalk or talc compounds. Magnesium-aluminium alloys which melt at approximately 850‹ F. may also be used for the intermediate layer.

Abstract: 954, 220. Gyromagnetic resonance apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct.17, 1960 [Oct. 20, 1959], No. 35496/60. Heading G1N. In a nuclear resonance spectrometer a standard sample, in addition to the test sample, is subjected to the main magnetic field, the standard sample also being subjected to the field of a high frequency (F 2 ) oscillator which is locked to a resonance frequency of the standard sample, a voltage proportional to the difference in frequency between F 2  and the high frequency (F 1 ) field applied to the sample under test being used to control the speed of the recording mechanism-paper displacement or oscilloscope time base-to maintain it proportional to the speed of scanning of the spectrum, and hence prevent distortion of the recorded spectrum due to inadvertent variations in the rate of change of the parameter-main field intensity or frequency F 1 -with respect to which the spectrum is scanned. When resonance occurs in the sample for measurement placed in the field of the main magnet NS and of the coil W supplied by oscillator F 1 , a modulated voltage from modulator B is applied to detector D 1 , the direct voltage output of which records the absorption amplitude on recorder R. The frequency F 1 , and the frequency F 2  which is locked to a resonance frequency of a water sample S t , are compared in a discriminator D 2 , from which is derived a direct voltage proportional to the frequency difference: the drive of the paper strip in the recorder R is controlled by, and is maintained proportional to, this voltage. The spectrum may alternatively be displayed on an oscillograph, the time base of which is controlled by the output of the discriminator D 2 .
