Title: Clamping body for use in performing operations on a workpiece
IPC: B23Q3/10
Filed: 1977-11-10
Abstract: The workpiece to be machined is clamped on a clamping body which is provided with positioning recesses on the surface accommodating the workpiece. These positioning recesses interact via inserted positioning elements with corresponding recesses (31) in the workpiece so that a reference coordinate system (X2, Y2) can be defined to which all dimensions of the workpiece can be referred. In order to be able to set the machining spindle of the machine tool for machining a workpiece, e.g. for producing bores (37, 38), the clamping body also has a reference coordinate system (X, Y). The latter is defined on the basis of reference bores (39, 40, 41, 42) or by the side faces (27, 28) of the clamping body. The workpiece is fastened to the clamping body by means of screws which are inserted in bores (53); it is then accurately defined in its position. With this type of clamping, the production of individual parts and small batches is considerably rationalised. <IMAGE>

IPC: C21D9/40
Filed: 1975-11-13
Abstract: 1498203 Discharging annular workpieces J AICHELIN 13 Nov 1975 [14 Nov 1974] 46845/75 Heading F4B A method of heat treating annular workpieces 6 comprises passing upright workpieces through a heating zone in an oven chamber 1 on pallets 5 and automatically removing the workpieces from one end of the chamber by picking the workpieces up either singly or in groups at the inner circumferences thereof by a longitudinally-displaceable extractor mandrel 16. The mandrel is introduced into the oven chamber via an opening 17 to engage the foremost workpiece by a hook 20. The mandrel 16 lifts a workpiece 6 out of the pallet 5 and conveys the workpiece out through the opening 17 to lie flat on a repository 19. As shown, the extractor mandrel 16 is eccentrically rotatable on its axis and carries on electrically conductive contact 23 which actuates a control device 22 for the operation of the mandrel. In another embodiment (Fig. 3, not shown), the rings are arranged on the pallets in groups extending at right angles to the direction of move - ment of the pallets through the oven. The transverse arm 13 is utilized to push the oven pallet situated at the end of the oven forward progressively by a fixed amount so that the foremost ring 6 is pushed onto the hook 20 of the mandrel.

Abstract: 1,103,622. Magnetic resonance apparatus. HILGER & WATTS Ltd. Nov. 25, 1964 [Nov. 28, 1963], No. 47054/63. Addition to 960, 927. Heading G1N. In a micro-wave resonance spectrometer the micro-wave power generated in a klystron 47, Fig. 1, is applied to a cavity 45 housing the sample through a directional coupler 48, attenuator 49, phase shifter 50 and a circulator and the energy reflected from the cavity is modulated in a crystal modulator 56 and is passed via the circulator to a detector 46 which also receives energy supplied from the klystron via the directional coupler. The detected signal is passed through an amplifier 58 to a phase-sensitive detector 59 fed from a signal generator 57 actuating the crystal modulator. A modified arrangement, Fig. 2 (not shown), has two directional couplers whereby the energy coupled to the detector from the power source may be adjusted without altering the power input to the cavity or the level of the signal reflected and may use a transmission modulator 76 and has a matched load 75 terminating one circulator port. The arrangement of Fig. 1 can be modified to employ a transmission modulator and a three port circulator and the arrangement of Fig. 2 can employ a reflection modulator and a five port circulator. The phase shifter is used to select the absorptive or dispersive component of susceptibility and may be located in the micro-wave circuit at any stage following the splitting of the input and preceding the combining of the modulated and unmodulated signals. There are described with reference to Figs. 3 and 4 (not shown) arrangements analogous to those of Figs. 1 and 2 respectively in which automatic frequency control is provided by two extra directional couplers, a phase shifter, a detector and a control unit comprising an amplifier, phase-sensitive detector and a D. C. converter are used to feed an error voltage via a klystron output to the klystron 47.

Title: Control apparatus for a three phase electrical motor
IPC: H02K11/00
Filed: 1975-01-17
Abstract: 1487652 Protecting motors against overload LENNOX INDUSTRIES Inc 17 Jan 1975 [24 Jan 1974] 47492/76 Divided out of 1487651 Heading H2K The disclosure is identical with that of parent Specification, but the claims are directed to a refrigerant compressor driven by a two-speed three phase motor with control apparatus to switch off the supply to the motor when the temperature of any of its stator coils exceeds a predetermined value. Linear or non-linear temperature sensitive resistors 284, 285, 286 are located in thermal contact with inner stator coils (112, 113, 114), Fig. 2 (not shown) and are connected as shown to form a bridge circuit with a resistor 290, the arrangement being such that the bridge is unbalanced to make a reference point 293 positive, when the coil temperatures are below a predetermined value and a switch 304 is closed to short out a resistor 306. Thus a semi-conductor relay circuit 294 is energized to switch on a Triac 300 in a supply lead (279) of a pilot circuit for relay coils controlling contacts connecting the inner and outer stator coils to a three phase supply, Fig. 2 (not shown). Excess temperature of one or more coils balances the bridge circuit to make the point 293 negative, deenergize circuit 294 and so switch off Triac 300. Thus the relay coils are de-energized and their contacts open to disconnect the stator coils from the supply. This condition lasts until the cooling of resistors 284, 285, 286 causes the bridge to become unbalanced in its original polarity direction, a time delay between motor switch-off and switch-on being provided by members 294, 304, 306, which operate to connect the resistor 306 in series with resistors 284, 285, 286 when the bridge becomes balanced and thereby make it unbalanced in the negative direction to maintain the relay circuit 294 de-energized and Triac 300 off. The supply lead (279) also includes contacts (58, 84, 92, 102), Fig. 2 (not shown), controlled by sensors responsive to compressor operating parameters such as temperature and gas pressure, whereby the motor is switched off when any of these parameters becomes abnormal.

IPC: F04C14/00
Filed: 1962-12-18
Abstract: 1,017,723. Gear motors. CESSNA AIRCRAFT CO. Dec. 18, 1962 [Feb. 23, 1962], No. 47770/62. Heading F1F. In a reversible pressure-loaded gear-motor, a sealing plate 34 is pressed against the gears 16 by fluid-pressure in a chamber 36 which is regulated in dependence on the speed of a power output shaft 20 by a control system, or mechanism, lodged in an end-block 28 situated between main fluid conduits, or lines, 12. The control system comprises passages 44, 46 communicating with main fluid-passages 30, 32, non-return valves 77a, 77b, 78a, 78b, annular chambers 42, 50, 64, two pairs of diametrally-opposite recesses 52, 54 communicating with chambers 50, 42, respectively, and a free-piston 62 slidably lodged in an axial bore 60 which is in communication with recesses 52, 54 through transverse bores 56, 58 and houses an end-closure plug 94 provided with a stop 96 for said piston. In operation, when fluid first flows through the motor in the direction of the single-tailed arrows, a proportion of the fluid enters the space beneath piston 62 through passage 44, valve 78a, chamber 50, recesses 52 and bore 58, whereby the piston is displaced upwardly to discharge a quantity of fluid through bores 56, recesses 54, chamber 42, a shallow recess 68 in shaft 20, chamber 64, valve 78b and passage 46. Subsequently, when shaft 20 is rotating, bores 56, 58 are periodically in register with recesses 52, 54 whereby fluid alternately enters the spaces above and beneath piston 62 so that pressure pulses are transmitted to chamber 36 through bores 38, 40. The restriction offered by recess 68 causes the pressure in chamber 42 to vary with the speed of shaft 20, thereby causing the pressure in chamber 36 to vary in a like manner. When the flow of fluid through the motor is reversed, as indicated by double-tailed arrows, valves 78a, 78b close and valves 77a, 77b open. Alternatively, the control system comprises a free-piston 162 (Fig. 6, not shown) lodged in a transverse bore 160 within a rotatable shaft which is driven by the power-output shaft 120a of the gear motor 110 and housed between two semicylindrical chambers 142, 150 externally of the motor. Chamber 150 receives high-pressure fluid from either of the conduits 12 through a pipe 144, or 146, and non-return valves 170 according to the direction of flow, whereas chamber 142 communicates with a pressureloading chamber 136 through a pipe 138, fluid being discharged from chamber 142 into pipe 144, or 146, through a flow-restricting orifice 166 and valves 170. Pressure-pulses transmitted to chamber 136, due to the oscillation of piston 162 in bore 160 when shaft 120a rotates, may be smoothed by the action of an hydraulic accumulator 163.

Title: Electrical resisitivity measuring equipment

Abstract: 1,007,822. Resistance measurements; semiconductor. STANDARD TELEPHONES & CABLES Ltd. Dec. 6, 1963, No. 48261/63. Heading G1U. A resistivity measuring device comprises a variable frequency source feeding two channels of similar transmission characteristics, comparison means for the outputs of the channels, means for varying the indicative coupling between two coils in the first channel by insertion therebetween of a sample of material of uniform thickness to reduce the transmission by a ratio linearly dependent on signal frequency, means for reducing the transmission of the second channel by a fixed ratio independent of frequency, and means for indicating signal frequency as a measure of resistivity. In Fig. 1 a variable frequency oscillator of e.g. 2-5 m/c/sec. series energizes two identical coils A, B coupled inductively to two identical coils C, D equally spaced therefrom, the outputs of such coils being respectively connected through a 62b. attenuator ATT and directly to differential amplifier DA and detector DET. Figure 2 shows the differential amplifier wherein the coil outputs are connected across respectively a 62b. 2-section attenuator R 2 , R 3  and an equal value resistance R 1 ; R 1  and R 2  being connected between the grids G 1 , G 2  of a parallel triode cathode follower V and RC shunt circuits C 1 , R 4  and C 2 , R 5  returned to a positive supply voltage, with a low frequency (e.g. 200 c.p.s.) square wave applied to the ends of the RC shunt circuits to alternately cut off the two sections of the cathode follower, whose output is applied to a RF amplifier and detector, and a LF amplifier feeding a phase sensitive rectifier energized from the 200 c.p.s. square wave supply to operate a centre-zero meter, which reads zero for equal inputs. A laminar sample of e.g. semi-conductor germanium or silicon is introduced between coils B, D and the energization frequency is readjusted to restore zero. It is shown that the ratio of coupling with sample present to coupling without sample between the coils B and D is proportional to p/f where p is resistivity of the sample and f is the energization frequency, so that for zero indication of the meter the sample resistivity is linearly proportional to frequency, so that the oscillator may be calibrated in terms of sample resistivity. Initial balance in absence of a sample is obtainable by removal of the 6db. attenuator and adjustment of the displacements between the coils e.g. by screw mountings until zero meter indication is obtained. Alternative ranges of measurement are obtainable by utilizing interchangeable coil units. Specification 1,007,821 is referred to.
