Abstract: 1,233,323. Tape transport. SONY CORP. 5 Sept., 1969 [7 Sept., 1968], No. 44010/69. Heading G5R. An automatically reversible taps transport apparatus enabling recording/reproducing in both directions is controlled by an "E"-shaped system of pivoted levers 26, 24, 30, 241 pivoted to the chassis at 41, 29, 41<SP>1</SP>. For forward motion of the tape, the "E" system is in the position illustrated, so that:- (i) lever 24<SP>1</SP> moves idler 11<SP>1</SP> into engagement between the hub 4<SP>1</SP>a of a flywheel 5<SP>1</SP> (driven by motor 7) and a clutch wheel (17<SP>1</SP>, Fig. 4, not shown) to rotate pulley 3 and thereby shaft 2<SP>1</SP> carrying the take-up reel 3<SP>1</SP>;  (ii) the end 24<SP>1</SP>a lifts a spring 21<SP>1</SP> to release a brake on the pulley 3<SP>1</SP>; (iii) lever 24 moves idler 11 away from flywheel 5 thereby removing the drive to shaft 2 carrying the supply reel 3; and (iv) the end 24a moves away from spring 21 so as to cause a brake to be applied to the pulley 3 (Fig. 4) and thus to shaft 2. Automatic reversal.-A metal foil on the tape may activate an electromagnet 27, Fig. 3 (not shown), to cause a lever 35 to be moved down so that it is rotated clockwise (in Fig. 1) by a stud 5a on the flywheel 5. This lever 35 is attached to lever 30 and its rotation causes the "E" system of levers to move to a second position (Fig. 2, not shown) whereby the positions of the idlers 11, 11<SP>1</SP> and brake springs 21, 21<SP>1</SP> are reversed and a switch 47 is activated by rod 48 to reverse the direction of the motor. Fast forwarding and rewinding is controlled by hand-operated levers 50, 51, respectively. When pushed upwards (in Fig. 1) the lever 50 (or 51) rotates the lever 63<SP>1</SP> (or 63) which pulls the pulley 57a into contact with pulley 3<SP>1</SP> (or 3) so as to drive it by motor 7. Simultaneously the lever 50 rotates the lever 71<SP>1</SP> so as to move the "E" system of levers 26, 24, 30, 24<SP>1</SP> into position to reverse the motor direction.

Abstract: 1,233,635. Machinery safety devices. CONCORDIA MASCHINEN-UND ELEKTRIZITATS-G.m.b.H. 28 Aug., 1969 [10 Sept., 1968], No. 42939/69. Heading F2J. In a machine, e.g. a press, having a driving eccentric shaft and a clutch and/or brake engaged or disengaged by fluid pressure under the control of a solenoid valve 1, a safety device provides a mechanical connection between the driving-shaft and the valve spindle 11 so that in the event of valve failure, the spindle is moved positively to, and locked in, a safe position. The valve 1 connects an outlet 3 to a clutch actuating cylinder with a pressure air inlet 2 in the position shown, Fig. 1, and with an exhaust port 9 in the "safe" position. A solenoid 10 and diaphragm servo 10a actuate the valve. For single-stroke working of the machine, the valve 1 is moved to its 'safe' position before the end of a cycle. The eccentric shaft drives a shaft 17 on which is keyed a cam disc 12 which actuates a plunger 16 coaxially abutting the valve spindle 11 via an arm 15 having a spring-retained pivot 20 at one end, the other end having a stop 18. In normal operation the valve spindle has already moved upwards (Fig. 1) when the cam 13 moves the plunger 16, the arm 15 pivoting about 20. If the valve spindle has not moved, the resistance causes the arm 15 to pivot about 18, raising the pivot 20 against spring force until a locking pin 22 is spring- urged under the arm to prevent its return, and hence any opening of the valve. Access to the pin 22 may be by key-holders only. To allow for continuous operation, the cam disc 12 may be slid axially on shaft 17 to a position clear of the arm 15, an inspection window 28 allowing the setting to be checked.

Abstract: 1,239,404. Stopping in predetermined position. S. G. DRAPER. 20 Aug., 1968 [23 Aug., 1967], No. 38721/67. Heading D1G. [Also in Division F2] Apparatus for arresting a sewing-machine spindle in a predetermined position comprises a rotary part arranged to be coupled to rotate with the spindle, braking means to co-operate with the rotary part for arresting rotation of the spindle, a fluid-pressure-operated piston and cylinder device for actuating the braking means, and means provided on the rotary part at a predetermined circumferential position for causing fluid under pressure to be supplied to the piston and cylinder device to actuate the braking means. As shown, a rotary part 13 having a spindle portion 17, a stem part 14 and a flange 13b is secured, together with a driving pulley 12, to the spindle 11 of a sewing machine 10. A sensing member 18 in the form of a piston is supported by a bearing liner 20 on the spindle portion 17, and together with a surrounding cylinder 22 is prevented from rotating by an anchoring stud (not shown) engaging in a fixed block. The cylinder 22 has an inturned flange 23 carrying an annular brake shoe 24, and the end of the sensing member 18 has a brake lining disc 36 adjacent the flange 13b. A tension spring 38 normally holds cylinder 22 to the left. When the brake is to be applied, air under pressure is admitted at 34, 31, to a passageway 30 in the sensing member 18 and may be free to flow into an annular channel 15 provided in the rotary part 13, and to escape therefrom through spaced radial passages 16: When, however, during rotation of part 13, a blocking member 33 disposed in the channel 15 comes opposite the exit of passageway 30, the air can no longer escape in this way, flows back around tube 31, impinges against the end cap 25 of cylinder 22, and forces the cylinder to the right against the action of spring 38. Flange 13b is thereupon gripped between discs 24 and 36, and the spindle 11 is stopped instantly in the desired position. Sliding movement of cylinder 22 is permitted by providing a slot in its wall for engagement with the anchoring stud referred to above. One or more further passageways 30' may be provided, in which case valves in the fluid pressure supply are selectively operated to feed one passageway only.

An addition-polymerizable polyester is obtained by reacting a lactone having 6 to 9 atoms in the lactone ring, not more than thirteen carbon atoms altogether and not more than two halogen substituents with an initiator in the presence of an acidic catalyst (other than trichloroacetic acid), wherein the initiator is of the general formula L-CM 2 -A-H. In this formula -A- represents -O-, -S-, -NH-, or -NR- (where R is an alkyl group having less than six C atoms), each group M is H, Cl, Br or R and L is any group having ethylenic unsaturation and containing no acid group provided that the total number of carbon atoms in the groups M, M and L, excluding any in aromatic rings, is less than 8. The temperature at which the polyester is prepared is such that little or no polymerization of the groups L occurs, preferably 35 to 100 C. The preferred lactone is #-caprolactone or a methyl #-caprolactone and the acid catalysts whose use is described and claimed in Specifications 1,201,909 and 1,210,496, e.g. p-toluenesulphonic acid, are particularly suitable. Examples 1 and 7 describe the use of #-hydroxyethyl acrylate and N-methylolacrylamide respectively as the initiator. The unsaturated polyesters may be copolymerized with monomers such as styrene in bulk or vinyl acetate in emulsion by conventional methods or may be reacted with addition polymers, e.g. P.V.C., when they act as internal plasticizers. Example 6 describes a paint based on a polyester-vinyl acetate polymer and containing also TiO 2 , methyl cellulose, sodium pyrophosphate and water. Reference has been directed by the Comptroller to Specifications 859,642, 859,643 and 859,645.

Abstract: 1289134 Automatic control systems HARTMANN & BRAUN A G 25 Nov 1969 [3 Dec 1968] 57541/69 Heading G3R The invention is concerned with preventing excessive overshoot in the response to a step change in the reference signal in a closed loop control system which could occur when the system is designed for optimum response to a disturbance. The closed loop control system receives a reference input signal w and is subject to a disturbance signal z, and provides a controlled output signal x. The signal w is applied directly to a junction 2 to be compared with signal x and form a deviation signal xw. The signal w is also applied to an attenuator 9 to provide signal kw which is added to the output signal V2y of an amplifier 8. A decaying function generator 7 receives the resultant signal and provides feedback signal xr which is added to signal xw to form an effective reference input to amplifier 4. The amplified signal y with any disturbance signal z forms the input to the controlled system 6. The signal y is also applied to amplifier 8. When the signal w is changed abruptly, for example when starting, the output signal x oscillates about the effective reference input to the amplifier 4 but not beyond the value defined by the signal w. An element having a proportional plus derivative action may be connected between the summation points 2 and 3, Fig.4 (not shown). In another arrangement, this element is located on the input side of the point 2, Fig.6 (not shown). It may be replaced by a delay member in the feedback circuit, Fig.7 (not shown).
