Title: Magnetic tape recorders with a tape drive pause device
IPC: G11B15/24
Filed: 1974-09-12
Abstract: 1462939 Tape recorder pause controls SONY CORP 12 Sept 1974 [17 Sept 1973] 39840/74 Heading G5R A magnetic tape recorder has a pause control 19 upon operation of which a pinch roller 15 is separated from a tape drive capstan 7 and then a switch 34 is opened to de-energize the electric motor 5 driving the capstan, switch 34 closing before roller 15 re-engages capstan 7 on return of control 19 from its pause position to its inoperative, normal position. Pressing a pause button 19 moves a slider 20 thereby moving a slider 22 which accordingly first pivots pinch roller 15 away from capstan 7 and then pivots roller 11, transmitting drive from motor 5 via belt 9 and pulley 10 to tape take-up reel drivewheel 4, away from wheel 4, whereafter on continued movement slider 20 reaches an extreme position on approaching which a pin 25 engages in a hook 29 of a latch plate 21 so that on release of button 19 from the extreme position spring 27 moves slider 20 back to a pause position locked by plate 21 which follows this return movement of slider 21 thereby opening power supply switch 34 of motor 5. On pressing button 19 from the locked pause position to the extreme position, pin 25 is released from plate 21 which is pulled by spring 31 to close switch 34, whereafter springs 27 and 41 return sliders 20, 22 to their inoperative positions whereby drive is again transmitted to wheel 4 and then roller 15 re-engages capstan 7.

Title: Alpha-halogeno-delta-unsaturated carboxylic acid esters and their cyclisation to substituted cyclopropane-carboxylic esters
IPC: C07D307/45
Filed: 1975-10-02
Abstract: The compounds of formula I' are prepared by cyclisation of the compounds of formula V in the presence of a basic agent. R<1> to R<4> represent H or a hydrocarbon radical, R<5> represents an alcohol residue and Y and Z each represent H or a halogen. R<1> and R<2> or R<1> and R<3> can be joined to form a ring with the C atoms to which they are fixed. The compounds of formula V are obtained by reaction of a 1-halo-3-alken-2-ol of formula II in which X represents a halogen with an orthocarboxylic ester of formula III. This process leads to the products of formula I' by a more economical route than the prior processes. <IMAGE>

Abstract: 973,410. Planing. RICHARD GARRETT ENGINEERING WORKS Ltd. Feb. 28, 1961 [Nov. 30, 1959], No. 40575/59. Heading B3L. A machine tool comprises a lost-motion mechanism for pivoting a tool 1 to-and-from working position. The tool 1 is clamped in a holder 1a which is angularly adjustable about an axis Y-Y on a clapper-box 2 pivoted to a holder 3 which is angularly adjustable on a slide 3a about an axis just below the axis Y-Y. The slide 3a is adjustable on a head 3b which is angularly adjustable on a ram 4. The ram carries a pivot pin 10 supporting an eccentric sleeve 11 carrying a hand-lever 13 and biased by a spring 15 to cause a double-armed lever 19, journalled on the sleeve, to be urged clockwise. The lever 19 carries an arcuate friction facing 21 to engage a friction slipper-pad 22 freelymovable between rubber buffers 30, 31. The lever 19 is connected by a ball-jointed rod 32 to a lever 33 fastened to the clapper box and limited in movement by an adjustable stop 45 and the clapper-box seating 6. At each reversal of the ram, therefore, the slipper becomes frictionally caught between the facing 21 and a guide strip 24 on the ram-slide thus causing pivoting of the tool. The mechanism can be put out of action by rotating the hand-lever 13 and tightening a lock-nut 17. In a modification, the tool is stationary and the guide strip 24, Fig. 5, is attached by an arm 62, or directly, to the reciprocating table 58. In further modifications, the lever 19 and eccentric 11 are replaced by a single lever, or the eccentric has set positions.

Title: Purification of tellurium
IPC: C01B19/02
Filed: 1961-11-23
Abstract: High purity tellurium is prepared by intimately contacting in a non-oxidizing atmosphere impure tellurium with an amount of zinc in excess of that required to form a water-soluble zinc telluride in an aqueous solution of alkali metal hydroxide of sufficient strength to prevent the precipitation of zinc telluride and oxidizing the telluride ion with, e.g. bromine, iodine or oxygen but preferably chlorine to form crystals of tellurium.  The ratio of tellurium to alkali metal hydroxide should not exceed 1.08 mol. of Te per 1000 g. of 11.7 molar alkali metal hydroxide.  The preferred alkali metal hydroxide is KOH.  The process may be conducted at 35-100 DEG  C., but preferably 50 DEG  to 80 DEG  C., under nitrogen.  The solution may be filtered before the telluride ion is oxidized.

Title: Improvements in and relating to transfer function analysers
IPC: G05B23/02
Filed: 1967-09-19
Abstract: 1,205,242. Transfer function analyzer. WESTON INSTRUMENTS Inc. Sept.19, 1967 [Sept.22, 1966], No.42489/67. Heading G1U. A transfer function analyzer incorporates a function generator for developing a sinusoidal wave to be applied as a stimulating signal to a system to be tested, in which generator separate signals representing points on rectangular waveforms and ramp waveforms respectively are produced selected and added in an appropriate sequence in accordance with the operation of a control system which incorporates a bi-stable circuit 154 to provide control signals at the mid points of the sinusiodal wave half cycles. The system to be tested provides resulting signals at a number of test points and these and the control signals are recorded in separate tracks of a recorder 166. The recorded resulting and control signals are played back simultaneously and a selected played back resulting signal e.g. on line 172 and the control signal on line 166a are applied to an analyzer 164 which determines the transfer function of the system in accordance with the selected signal in time synchronizm with the sinusoidal waveform from the function generator. A second bi-stable circuit 186 connected to the playback system changes state in synchonizm with the played back control signals to provide signals applied via a gate 192, 194 to switch the first bi-stable circuit 154 in accordance with played back control signals, so as to synchronize the sinusoidal wave from the function generator with the played back signals. The function generator, Fig.3B (not shown) in which rectangular and ramp waveforms are appropriately added in accordance with the control signals is similar to that shown in Specification 1,016,341, the timings of the separate steps in the synthesized sinusoid waveform from the generator being controlled by clock pulses. However the 90 degrees positions, at which ramp waveforms of reverse slope must be switched in, are controlled by signals on the lines bcd from the bi-stable circuit 154. As explained above, the operation of this is locked with played back control signals so that the function generator operation is locked to to the playback, when the gates 192, 194 are enabled by a tape playback signal. The signals from the bi-stable 154 are applied to the analyzer 164, to which also the test signals from the different recorder channels are applied in turn. The analyzer system is similar to that described in Specification 1,016,341. Two resolvers 161 and 162 respond to the test signals and to a waveform synthesized at 20a in response to control signals to provide outputs to two integrators 63 and 63a, the outputs from which provide the measurement output of the system.
