Patent GB-1286980-A (GB)
Title: Discard device for calculating machines
Inventor: HABERKORN OTTO
IPC: G06C15/24
Filed: 1969-12-15
Abstract: 1286980 Calculating machines WALTHER-BUROMASCHINEN GmbH 15 Dec 1969 [14 Dec 1968] 61083/69 Heading G4B [ A discard device for calculating machines comprises a value recording unit having a shaft guided between two guide levers and carrying a set of gears arranged to be coupled intermittently to the transmission elements of the machine, the value recording unit being slidable under control of lever means so that it can provide rounding-off. A value recording unit 6, is disposed for lateral sliding and mounted for rotation by means of frame 18 mounted on shaft 17. A set of gears 23, each of which has a lateral zero cam lying opposite a zero stop bar 25 on the unit frame 18, is mounted on shaft 22 supported in the curved slots 21 of guide levers 20. A counterclockwise swivelling of guide levers 20 raises gears 23 into contact with transmission elements 43 for the introduction of a value into the value recording unit 6, or its subsequent removal. The value is rounded-off, following the movement of the value recording unit to the left as viewed from the direction of arrow A by the action of spring 49 acting through lever 45 and pin 46. The movement, which is normally blocked by the abutment of pin 50 and stop surface 52, is permitted by the movement of lever 55, so that pin 63 occupies the central notch 61, thus moving stop slide 51 so that lever 45 can rotate until pin 50 abuts surface (96, Fig. 5, not shown) of the second stop slide 64. The value recording unit 6 is thus displaced two places to the left so that the two least significant figures can be discarded, with rounding- up of the third least significant figure if the second least significant figure is five or above. A sensing lever 39, Figs. 2, 3, which slides with the gears 23 is rotated so that lug 41 is pushed against the transmission element 43 of the second least significant figure. If this transmission element has been displaced five or more units, to set the corresponding gear at 5 or over, the lug 41 can engage in the teeth of the transmission element 43 as indicated at 41<SP>1</SP> of Fig. 2, in which case the rotation of lever 39 is sufficient for the lug 44 at its opposite end to strike a tens transfer lever 34 and thus allow it to add one unit to the third least significant figure. If however the transmission element 43 of the second least significant figure has been displaced less than five units lug 41 will lie against the teeth 42 and the rotation of lever 39 will be insufficient to free the tens transfer lever 34. Operation of lever 73 moves stop slide 64, so that pin 50 abuts surface (98, Fig. 6, not shown), with consequent rounding-off of the third least significant figure and simultaneous displacement by one place of the decimal point indicator 97, Fig. 3. Full displacement of lever 55, so that pin 63 occupies notch 62, rounds-off the four least significant figures and thus facilitates multiplication, and other power calculations.

Abstract: 1279469 TiO 2  fibres FARBENFABRIKEN BAYER AG 29 Dec 1969 [2 Jan 1969 28 Aug 1969] 63070/69 Heading C1N Fibrous TiO 2  is made by contacting one or more titanium tetra-halides at above 600 C., e.g. 750-950 C., with a melt of one or more salts of an inorganic oxygen-containing acid which is capable of forming a volatile anhydride under the reaction conditions; and then recovering fibrous TiO 2  from the reaction medium. The titanium tetra-halide, e.g. TiCl 4 , may be mixed with a carrier gas, e.g. air or N 2 . The melt may be a sulphate polysulphate, disulphate, thiosulphate, sulphite, disulphite, carbonate, nitrite, nitrate or phosphate, and may also contain a metal halide. Excess titanium tetrahalide may be condensed and recycled. The TiO 2  fibres or whiskers, having an aspect ratio of at least 10 : 1, e.g. 100 : 1 to 2000 : 1, are recovered by dissolving residual melt in water, and separating the TiO 2  from the aqueous solution. Examples describe the production of TiO 2  fibres by passing TiCl 4 -loaded N 2  over melts of (1) Na 2 SO 4 +MgSO 4 ; (2) Na 2 SO 4 +MgSO 4 + NaCl; (3) Na 2 SO 4 +MgSO 4 +LiCl+NaCl; (4) K 2 SO 4  + CaCl 2  + LiCl ; (5) ZnSO 4  + CaCl 2  + KCl; (6) ZnSO 4 +KCl; (7) NiSO 4 +NaCl; (8) CuSO 4  + NaCl; (9) CdSO 4 +CaCl 2 +NaCl; (10) KAl- (SO 4 ) 2  + CaCl 2  + NaCl.

Title: Preset state indicating unit in an electronic tuning type receiver
IPC: H03J5/02
Filed: 1978-06-28
Abstract: An electronic tuning type receiver includes a memory (9) into which frequency data is written when the user simultaneously operates a presetting switch (11) and one of a plurality of channel selection switches (7a to 7e). To verify that these switches have been correctly operated to write the data into the memory, there is a preset state indicating unit which includes an OR gate (12) with inputs connected to the various channel selection switches, a flip-flop (13) with its SET terminal connected to the WRITE input of the memory (9) and its CLOCK terminal connected to the output of the OR gate. The Q output of the flip-flop drives an indicator (16). The flip-flop acts as a one-shot circuit causing the indicator to light, if the OR gate is producing an output at the same time as there is a WRITE input to the memory. <IMAGE>

Title: Limit setting mechanism
IPC: H01C10/14
Filed: 1978-11-07
Abstract: The extent of movement of a shaft 3 of an adjustable component, such as a potentiometer 1, is limited in one sense by a stop, and the position of the stop can be altered only after the release of a security lock associated with a second shaft 13. Hence the limiting value at which a plant may be tripped cannot be raised without access to a key for the lock.

Title: Method of connecting cables
IPC: H01R4/20
Filed: 1979-08-16
Abstract: An electric cable (1) is connected with a tubular connector (2) by crimping in at least two places (3, 4) by the application of radial force.
