Abstract: 1,170,897. Abrading. SIEMENS A.G. 1 March, 1968 [3 March, 1967], No. 10004/68. Heading B3D. A process for lapping and/or polishing a plurality of plate-shaped semi-conductor crystals comprises sticking the plates 5 to a carrier 6 in such a way that their flat surfaces to be worked are all in a single plane, bringing and holding the plates in contact with the surface of a lapping and/or polishing tool in such a way that at and from the moment of first contact the working surface of the tool coincides with the plane of the surface of the plates to be worked, and moving the carrier relative to the operating surface of the tool. For mounting the plates on the carrier, a ring 1 is provided having a number of columns 2, the upper surfaces of which are in a common plane and each of which have a ring of suction holes or a single annular suction gap whereby the plates can be held one to each column with the surfaces to be lapped engaging the upper surfaces of the columns, the plates being initially positioned by being placed in recesses 5 in a template 4, the recesses corresponding to the columns. When the plates are held by suction on the columns, adhesive, such as beeswax, is placed on the upper surfaces of the plates and the carrier 6, which has been heated, engaged with the plates. Upon cooling of the carrier, the suction is switched off so that the carrier now holds the plates with the surfaces to be lapped in a common plane. The carrier plate is then applied to the lapping or polishing tool so that at the first moment of contact, the working surface coincides with the plane of the surfaces to be worked.

Abstract: 1,084,155. Making electrical connections. AMP Inc. March 17, 1966 [March 22, 1965], No. 11638/66. Heading B3A. In a tool for making an electrical connection between a wire and a terminal post by a clip telescopically movable on to the post, a clip is placed in the cavity of an enlargement 26 of a shank member 20, retaining means within the cavity being arranged releasably to retain the clip and a trip hammer device 82 is arranged to be tripped on rearward movement of the shank member to apply an impact to the shank member. The stripped end (14), Fig. 6 (not shown) of a wire (12) is placed against the clip in the cavity and the clip is then aligned with a terminal post which may penetrate within the channel section of the shank member 20 behind the enlargement 26. A hammer block 82 is withdrawn until its front face clears a lip 100 of a latch plate 94 which is upwardly directed by a spring 108. The clip is then pushed on to the terminal post, thereby forcing back the member 20 to which is riveted a yoke 76 fitted with a striker plate 80. The striker plate 80 pushes down an ear 102 of the plate 94, thereby releasing the hammer block 82, which impacts the striker plate. The impact force is transmitted to the shank member 20 to drive the clip and wire along the post. Further movement along the post may be effected by manual pressure.

Abstract: 1,108,624. Break-spinning apparatus. VYZKUMNY USTAV BAVLNARSKY. 22 March. 1966 [7 Dec., 1965], No. 12515/66. Heading D1D. In break spinning to prevent breakages or the formation of slubs arising from an accumulation of fibres on the edge 9 of the knife 10 which removes the comed-out fibres from the combing-roller 3, a duct 11 is previded for supplying air under pressure to the edge. The combing-roller rotates in a body 1 and fibrous material is supplied to it through a duct 18 by a roller 2. The fibres are separated by needles on the roller and are conveyed to the spinning-chamber along a duct 5 through which air is drawn as the chamber rotates. The fibres are detached from the cylinder by the edge of a knife formed by the intersection of the duct 5 with the hollow space in which the roller rotates. To prevent the accumulation on the knife-edge of fibres which give rise to slubs or untwisted, weak. places in the yarn, the channel 11 conducts air under pressure arising from the rotation of the chamber, to a point below the knifeedge. The air is conducted from the spinning chamber through a diffuser and a device 20 by which the pressure is controlled. The speed of air in channel 11 is less than that in duct 5 which in turn is less than the surface speed of roller 3.

Abstract: 1,227,198. Proximity detectors. EXPRESS LIFT CO. Ltd. Oct.24, 1969 [Oct.31, 1968], No.51709/68. Heading G1N. [Also in Divisions E2 and H2] An electric motor closing the sliding door of a lift is reversed when a mechanical or a capacitive detector detects a body in the path of the door. The capacitive detector comprises two vertical parallel conductors embedded in the strip. The capacitance between the two conductors forms one arm of a bridge circuit, the other arms being formed by an adjustable capacitor and the two parts of a tapped inductance or, alternatively, the two parts of a transformer winding. When the conductors approach a body the capacitance between them alters, and a signal appears at the bridge output. The signal is amplified to actuate contact points to reverse the motor. The sensitivity of the capacitive detector may be varied by using conductors of different length, or by using three or more conductors where each pair of conductors has a different spacing.
