Abstract: 1382107 Time control of heating installation; automatic temperature control systems M SMITS 7 April 1972 [8 April 1971] 16174/72 Headings G3R and G3T  A device 2 switches over a heating installation in a building from low power to full power at a time which is adjusted in dependence upon the temperature inside the building measured by e.g. a mercury contact thermometer 1. Projections on cams 3a, b, c, rotated by a clock motor 3, actuate switches 2a, b, c at three different pre-set times, but current flows through device 2 only if a circuit is completed by contacts 1a, b, c which correspond to three different temperatures. The device 2 switches the heating installation from full power to low power at a time controlled by a second device similar to the above, connected to a contact thermometer outside the building. A further thermometer 6 senses the outside temperature and actuates a regulator 5 which may move the switches 2a, b, c relative to cams 3a .. 3c to alter the time of switching-over of the first mechanism. The contact thermometers may be replaced by resistance thermometers or thermocouples.

Title: Method of and apparatus for checking the geometrical features  of mechanical workpieces in particular for measuring  concentricity and roundness
IPC: G01B21/30
Filed: 1974-04-11
Abstract: 1463533 Concentricity and roundness measuring M POSSATI [trading as FINIKE ITALIANA MARPOSS-SAS DI MARIO POSSATI & C] 11 April 1974 [19 April 1973] 16392/74 Headings G1M and G1N In a method of and apparatus for measuring the concentricity and roundness of features in a mechanical workpiece, e.g. valve guide holes and valve seats of internal combustion engines, one set of size checks is performed on different sections of a nominally cylindrical surface, a second set of checks being performed on a single nominally circular section of another surface of revolution, both sets of checks being carried out around the whole circumference of the sections, the data resulting from both sets of checks being processed to derive an indication of the concentricity error of the two surfaces, the roundness of the section of the surface of revolution being determined on the basis of a computation with the data resulting from the second set of checks. In the described embodiment, the first set of checks is performed by feelers 17, 18, the second set by feelers 19, 20, a further feeler 22 producing a signal compensating for axial displacement of plug 14. Displacements detected by feelers 17, 18, 19, 20, 22 are transformed into electric signals each being associated with an induction position transducer and with detecting circuits to form an electronic gauge.  The head 13 under test is inserted into a housing, lever 56 being operated so as to raise thrust element 74a together with a second element associated with a second piston (not shown) and thereby position the head 13 against reference elements 54a, 54b, (54) Fig. 2 (not shown). Actuation of a second lever 57 is then possible, so as to raise stem 79 into guide hole 12 of head 13. Failure of the stem 79 to enter hole 12 does not allow operation of a third lever 58, and indicates that the hole 12 is out of tolerance in some respect, this step preventing possible jamming of plug 14 in head 13. Activation of lever 58 thereby lowering the plug 14 moving stem 79 until arrested by a mechanical reference. A motor 43 rotates the plug 14 and the measurements are then carried out being reckoned on the basis of equations given in the specification.

Abstract: 871,033. Washing machines. GENERAL MOTORS CORPORATION. May 13, 1959 [May 28, 1958], No. 16414/59. Class 138 (2). [Also in Group XXIV] A washing-machine motor (34, Fig. 2 or 98, Fig. 3), is rotated in one direction to reciprocate an agitator and in the opposite direction to produce a high-speed spin. In Fig. 2, the motor shaft 50 carries freely-rotatable pulleys 54, 56 which can be coupled to the shaft 50 through a screw clutch 58. Clutch 58 comprises friction facings 74 on a nut member 72 threaded on a clutch screw 66 keyed to shaft 50. According to the direction of rotation of motor 34 and due to the inertia of nut member 72 drive is transmitted through a belt 84 or 86 to a pulley 46 or 48 fixed to a rotatable housing 26. When housing 26 is rotated in one direction by belt 86, an agitator shaft 24 is reciprocated vertically, and when rotated in the opposite direction by belt 84, agitator shaft 24, and tub shaft 25, are rotated. In Fig. 3 the motor shaft 100 carries oppositely-threaded portions 104, 106 and stop members 108, 110. When the shaft rotates in one direction a drive roller 112 moves axially to transmit highspeed drive to an inner spin track 96 and a drive roller 116 moves axially, free of an agitate track 94. Reverse rotation transmits low-speed drive through roller 116, and roller 112 is free. Tracks 94, 96 are bolted to a housing 26 containing mechanism similar to that in Fig. 2.

[Classes 38 (iii) and 38 (v)] No-volt release; push-button control systems.- A control system comprises a push-buttonoperated main contactor 1, the operating coil 2 of which is adapted to be connected across two supply-lines, the contactor being provided with an auxiliary time-delay contact 5 which causes reclosure of the main contactor if the line voltage returns, after wholly or partly failing, within the time-delay period thereof, and, during this period, a circuit is maintained across the contact 5, the operating coil 2, and a contact 9 of an auxiliary relay, which latter contact is open in normal operation when the auxiliary relay is energized. When an " off " push-button is actuated, the time-delay in opening of the main contactor is not afforded. Actuation of a push-button 10 effects closure of the main contactor 1 together with its auxiliary contacts 3, 4 and 5, there being no time-delay in closure of the contact 5. On release of the push-button, the circuit through the coil 2 is maintained through the contact 3. The auxiliary relay coil 8 is energized through the contact 4, the contact 9 taking its righthand position. On failure of the supplyvoltage, the coils 2 and 8 are de-energized, but a circuit to the coil 2 is maintained through contacts 9 and 5, as long as the latter is in its closed position. If a push-button 11 is actuated, with the supply voltage at its normal value, the coil 8 is maintained energized through the contact 9, and the time-delay contact 5 is rendered ineffective. The contactor 1 may act as a pilot contactor and may be of the two-pole type.
