IPC: C07F7/22
Abstract: Cyclohexyltin compounds having the formula (C6H11)3SnX where X is chloride or bromide are prepared by reacting (C6H11)MgX with SnX4 in a molar ratio of 3+0.3:1.  The cyclohexyl radical may contain inert substituents, e.g. hydrocarbon residues.  The mixture at the commencement of the reaction may contain SnX4 in excess of (C6H11)MgX, and the (C6H11) MgX and the remainder of the SnX4 are added simultaneously in molar ratio of 3:1.  The (C6H11)MgX is added as a solution of its ether complex in aliphatic ether or as its ether complex in cyclic ether containing 5 to 6 members in the ring, e.g. tetrahydrofuran, tetrahydropyran, dihydropyran and N-methylmorpholine. The reaction mixture is maintained at 25 DEG  to 95 DEG  C.

The wall thickness of an extruded tube is varied during extrusion by accumulating a predetermined quantity of plastics material in a chamber and thereafter moving a member thereinto at a predetermined, varying speed by a single-acting piston and cylinder to extrude material from the chamber through a nozzle of constant cross-section. Material is fed along barrel 10, Fig. 1, of an extruder by screw 11, through conical passage 14 into accumulator chamber 13, forcing ram 18 upwardly. When a predetermined quantity has been accumulated, a switch (not shown) may be actuated to start extrusion by downward motion of ram 18 at a varying speed. This is controlled by a piston 20 in an hydraulic cylinder 21 to which fluid supply is controlled by valve in accordance with a cam surface 26 mounted on the piston-rod 19 and a follower 27.

Abstract: 1,252,455. Cathode-ray tube displays. MARCONI CO. Ltd. 10 March, 1969 [2 May, 1968], No. 20787/68. Heading H4T. Pulses, which are produced by a light-pen when it intersects the boundary of an area traced on the screen of a cathode-ray display by means of an auxiliary co-ordinate deflection system are utilized via a main deflection system to cause the area to follow movement of the light-pen across the screen. The area which comprises a rectangular "box" repeatedly traced at relatively high speed, is produced by the application to the auxiliary deflection means (not shown) of co-ordinate deflection signals - X, +Y, + X and - Y (Fig. 1), derived, respectively, from stages 2 ... 5 (Fig. 2), of a shift register synchronized by pulses fed via terminal 7, a further stage 6 supplying clamping pulse which hold the deflected beam at the position determined by one deflection signal until the next deflection signal is produced. The "light-pen", which is positioned as shown by the small circle in Fig. 1, comprises a fibre-optic and an associated photo-electric device 1 (Fig. 2) the (pulse) signals produced by which are supplied via an amplifier 8 as one input to four co-incidence gates 9 ... 12 the other inputs to which comprise the co-ordinate deflection outputs of stages 2 to 5 of the shift register, delay devices 13 ... 16 being included to ensure that the outputs from the appropriate stage reach gates 9 to 12 simultaneously with pulses produced by the "light-pen" when the corresponding side of the "box" is traced. As each side is traced the outputs of the register gates, which are fed to the auxiliary deflection means (not shown), are supplied to an OR gate 17 which supplies bright-up pulses (BU, Fig. 3) for the beam so that each tracing of a side produces a pulse via the " light-pen " when the latter is positioned over such side. The outputs of the coincidence gates 9 and 11 and 10 and 12 are then utilized to control respective UP-DOWN counters 18 and 19 respectively which via the main co-ordinate deflection means (not shown) cause the position of the " box " to move across the screen as the " light-pen " is moved until the latter ceases to produce an output signal (i.e. when the " light-pen " is in the centre of the "box ").

Abstract: 1,265,541. Dictation apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 29 May, 1969 [17 June, 1968], No. 27177/69. Heading H4K. [Also in Division G5] In the remote control of a dictating machine audio frequency tones are sent on the same line as the speech signals and are detected to provide control signals to operate a recorder where provision is made to prevent the tones being recorded. As shown, the recording assembly is connected through interface 4 to the telephone network and access is gained through hybrid 23 and A.G.C. circuit 26 to recorder 20. The recorder is of the magnetic belt type and is controlled by signals emanating from a logic circuit, Fig. 6 (not shown), which itself receives an input from tone detection circuit 30. The substation equipment 1, 2 must be provided with tone sending equipment for operating the recorder and six keys are used to provide start and stop, playback backstep, playback forward step, end letter mark, instruction mark and to call the attendant.  Operation.-If recorder is functional and at least 4 minutes recording time is available standby tone is returned by the 1050 Hz oscillator 31 and the recorder can now be operated by depressing the required keys. To prevent the stop tone remaining on the tape at the end of a recorded passage, the recorder automatically reverses and erases this length of tape. End of letter and instruction marks are punched on a conjoint index tape to prevent access to previously recorded material. Timer 11 functions to disconnect the system if no action is taken by the subscriber and the attendant can interrupt using handset 38. In an alternative system, the subscribers are connected to the recorder assembly through a buffer circuit which includes a voice operated relay (VOR), Fig. 1c (not shown). In this case the changeover from ready to record is caused by the response of this relay and thus a subscriber instrument without a tone generator is able to record a message but cannot otherwise control the operation of the recorder. Voice signals after being detected in the hybrid are passed through a 200 ms. delay so that the recorder has time to be operating and does not miss any speech signals. Since the operating signals to the recorder are instantaneous with the passing of a key or operation of the VOR no control tones can be recorded but 200 ms. of speech will be lost when speaking stops, but this is not found to matter. Normally, the recorder operates on termination of a control tone as determined by latches in the logic circuitry when switched from the stop into the record mode.

Abstract: 1289536 Film metering mechanism EASTMAN KODAK CO 25 Sept 1969 [28 Sept 1968] 47266/69 Heading G2A The transport of a film-strip 5 is terminated by the entry of nose 7c of a slide member 7 into a film perforation 5a under the action of spring 8. This action is supplemented by an additional force which acts only during the period in which the film wind is actually being operated. As the film wind lever 1 is turned from the position of Fig. 1 (not shown), in which the shutter has just been released, to the position of Fig. 2, the film is wound on and slider 7 moves upwards to engage in the perforation 5a. At the same time, a cam portion 1b of lever 1 causes a lever 3 to pivot about its spindle 3a, so that a leg 6a of a spring 6 carried by lever 3 bears against a projection 7a of slider 7. This provides an additional upward force on slider 7 besides that provided by spring 8. A further lever 11, also mounted on spindle 3a, is pivoted by a further projection 7e of slider 7, until its other end 11a, shaped as a pawl, engages in a ratchet 1c on lever 1, so preventing any further rotation. The film is now fully transported, and the shutter cocked. A pawl 9, normally locking slider 7 against upward movement, is also pivoted away by lever 3. Fig. 2 shows the position at the end of the film transport and shutter cocking movement of lever 1. Lever 1 is now returned to its normal position, Fig. 3 (not shown) by spring means (not shown), and the camera is ready for taking a photograph. During this return movement of lever 1, leg 6a of spring 6 is withdrawn from projection 7a, so that the additional upward force no longer acts on slider 7, which is retained merely by spring 8 alone. When the exposure is made by pressing the release member 12, 13, this at the same time pivots a lever 14 to draw slider 7 downwards again, during which movement only the force of spring 8 has to be overcome.
