Title: Improvements in cylinder grinding tools
IPC: B24B33/08
Filed: 1946-05-22
Abstract: 619,685. Cylinder honing tool. DEHN, S. G. (Automotive Maintenance Machinery Co.). May 22, 1946, No. 15529. [Class 60] In a cylinder grinding tool having carriers for abrasive elements expanded by a spring unit, the spring unit has one portion with a low deflection and highfrequency characteristic and a coacting portion with a high deflection and a low-frequency characteristic. The abrasive carriers 14 are expanded by cones 24, 25, threaded on a stem 21 to the upper end of which is secured an adjusting knob 34. An opening 30 is provided in the head 23 of the tool and in this space is located a washer-like spring 31 having a highfrequency characteristic and a coil spring 32 having a low-frequency characteristic, the upper end of the coil spring bearing against the skirt 33 of the knob 34. The lower end of the stem 21 carries a stopblock 36 which fits into an opening 22 in the lower end plate. In use the knob 34 is turned to shift the cones axially and expand the tool until the abrasive elements are in firm engagement with the cylinder wall. Further rotation of the knob 34 moves the stem 21 downwards against the pressure of springs 31 and 32, the amount of this further movement being indicated by a marked sleeve 37. As the grinding operation proceeds the tool will expand under the pressure of spring 32 until the lower end of the stem is withdrawn into the body of the tool, when the stop-block 36 will seat into the gearing 22 and prevent further expansion of the tool. The washer spring 31 is stated to respond to high-frequency vibrations of the abrasive elements, so that the latter maintain a rapidly-vibrating contact with the cylinder wall and do not become clogged or glazed.

Title: Tape cassette
IPC: G11B23/28
Filed: 1976-04-15
Abstract: 1501075 Tape cassette SONY CORP 15 April 1976 [17 April 1975] 15689/76 Heading B8M In order to prevent inadvertent erasure of recordings on a tape 3 of a cassette T a safety device 20 of the cassette is moved from its first releasably locked position to its second releasably locked position wherein access to a recess 22 in the cassette of an actuating element 36 of a tape recording/reproducing apparatus is unblocked. In the first locked position, wherein access to the recess 22 is blocked, a projection 32 on a resilient arm 31 of the device 20 positively engages a through-hole 32 on the peripheral wall 1c of the cassette. In the second locked position the projection 32 positively engages a second through-hole 34 on the wall 1c. The element 36 is part of a microswitch 35. The device 20 is unlocked from each of its locked positions by pushing the projection 32 from the corresponding through-hole inwardly into the cassette using a pencil or other pointed element. The apparatus includes cassette locating means for positioning the cassette at an operative position in the apparatus. The device 20 comprises resilient arms 41a and 41b for engaging in notches 39a and 39b respectively to facilitate the attainment of the first locked position and for engaging in notches 40a and 40b respectively to facilitate the attainment of the second locked position. In another embodiment, Figs. 7-9 (not shown), the projection (32<SP>1</SP>) and one of the resilient arms (42<SP>1</SP>a) of the device (20<SP>1</SP>) are integrally made. Also, to prevent the device (20<SP>1</SP>) from coming out of cassette T a bead (41<SP>1</SP>b) of the other resilient arm (42<SP>1</SP>b) pressingly engages an indentation (43b) provided on a wall 1b of the cassette housing. The cassette includes pivotable lid members 8a and 8b which are moved from the closed position of Fig. 1 to permit the withdrawal of the tape along the opening 2 of the cassette. Apertures 38a and 38b are provided in the cassette T to expose top and bottom walls 27, 28 of body portion 25 of the device 20 when in the second locked position. Frangible tabs 10 of the cassette can be selectively removed so that the presence or absence of the tabs 10 can be detected by detecting levers (not shown) of the apparatus. The degree of displacement of the levers is used to establish the correct tape transporting speed and/or the correct equalization and bias current for the magnetic material of the tape 3. The safety device is moulded of a suitable plastics resin.

Abstract: 253,360. Rogers, F. H., (Republic Flow Meters Co.). June 17, 1925. Dynamometers. - In measuring the efficiency of electric power units comprising a steam turbine or other prime mover 10 and an electric generator 11 by means of an indicating instrument having two circuits, the current in one circuit is controlled according to the load output of the unit, and the current in the other circuit is varied inversely as the power supplied to the unit by a U-tube 15 containing a balanced column of mercury 16 controlling the current in the circuit and operated by the differential pressure set up by an orifice 14 in the conduit 13 supplying steam or other power medium to the turbine &c. The mercury may vary a non-inductive resistance 21 through contacts 22, the resistance 21 being in series with the pressure coil 20 of a wattmeter or the moving coil of an electrodynamometer, the current coils 19 or stationary coils being in series with the load 18. In the case of a polyphase generator, one indicating instrument is sufficient if the load is balanced, but, if the load is unbalanced, the number of instruments and resistances is one less than the number of wires leading from the generator.

Abstract: 1420830 Making dry shaver cutters RONSON PRODUCTS Ltd 1 April 1974 [2 April 1973] 15759/73 Headings B3E and B3A [Also in Division B4] A method of making an inner cutter for a dry shaver of the kind comprising a perforated foil against which is reciprocated an inner cutter having a plurality of blades mounted in a rigid support, consists in corrugating a ribbon transversely to its length and winding the corrugated ribbon on edge to form a helix. The ribbon may be wound so tightly on a mandrel that the latter serves as the final support, or the inner edge of the helix may be adhered to the mandrel. Alternatively, the ribbon 4 is removed from the mandrel, and partly embedded in a body or metal or plastics 5 constituting the final support. At least half of each turn may be embedded, or all but the outer edge of the turns may be embedded. Finally the exposed outer edge of the helix is ground to a cutting edge.
