[Class 35] A starting mechanism for a small motor, particularly for dry-shavers, comprises a manually-actuated pawl adapted to swing about its pivot and engage projections on a starting member, the interrupter of the motor being simultaneously released to complete the motor circuit, means for displacing the pawl sideways out of the path of the projections while it is returning to its initial position also being provided. As shown, the pawl 10 is pivoted at 11 and operated through a connecting link 17 from a manually-operated switch disc 19 pivoted at 18. A rocker 12 is mounted on the same pivot as the pawl and a spring presses them together at 13. The operating link pivot 14 is provided with a rounded head projecting into a hole in the rocker 12 and when relative displacement of the pawl and rocker takes place, the pawl is displaced axially against the spring pressure. A starting disc 7, mounted on the motor shaft, is provided with beakshaped axial projections 8 which are engaged by the pawl in its travel from left to right in Fig. 2. Friction between the pawl and rocker causes these to rotate together about pivot 11 until the rocker engages the right-hand stop 16. Further motion of the pawl displaces it relatively to the rocker and it is displaced axially to disengage the projections 8. Simultaneously with this movement, the camdriven interrupter 5 is released from a restraining arm 27 which is raised about a pivot 26 by a pin 24 carried on the disc 19. During its return motion the pawl is maintained in its displaced position until the rocker 12 is restored to its initial position relative to the pawl by engaging a left-hand stop 16.

Abstract: 805,645. Locks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 16, 1957 [April 19, 1956], No. 12009/56. Class 44 A key operated safety lock comprises a bolt 3 adapted to be actuated by a key which cannot be withdrawn unless the bolt is in the locked position; a detent 5 arranged to prevent the bolt being moved from the unlocked to the locked position; and means 6, magnetically actuatable 10 from outside the lock, for withdrawing the detent to permit the bolt to be moved to the locked position. As described, the bolt 3 is rotatable in its own plane through a right angle by means of a barrel lock 1 which is of known construction such that the key can only be removed when the bolt is in the locked position. The bolt has a raised portion 4 on one face and the detent 5, which is carried on an arm 6 mounted on a pivot 7, is urged into engagement with the side face of the bolt 3 by the spring 8 biasing the arm 6 towards the bolt; rotation of the bolt into the locked position is thus prevented by engagement of the detent 5 with the edge of the raised portion 4. The lock is mounted upon the door of a housing, and the housing carries a magnet 10 disposed in such a position as to attract the arm 6 and disengage the detent 5 from the bolt 3 only when the door is closed. Thus the key can only be withdrawn from the lock when the bolt 3 is shot, and the bolt 3 can only be shot when the door is closed. It is also stated that the magnet may lie within the lock and be attached to the detent, and a ferromagnetic member may be mounted on the housing so as to cause the magnet to move and disengage the detent when the door is closed.

Title: Improvements in or relating to melt-spinnable compositions
IPC: C08L39/06
Filed: 1960-04-06
Abstract: A single phase melt-spinnable composition comprises (1) an amide type synthetic linear fibre-forming condensation polymer and (2) a water-soluble poly(N-vinyl amide) having a main polymer chain consisting substantially exclusively of carbon atoms. Preferably (2) remains water-soluble after heating, and the specified materials are polymers of N-vinyl lactams or N-vinyl N-alkyl aliphatic amides (including lactams wherein the vinyl group is substituted by alkyl or acyl, and amides wherein the vinyl group is separated from the N atom by methylene groups), e.g. poly (N-methyl-N-vinyl-formamide), poly (N-vinyl-propiolactam), poly (N-vinyl-valerolactam) and in particular poly (N-vinyl-pyrrolidone). The preferred condensation polymer (1) is a polyamide, e.g. 6 nylon, 66 nylon or 6,10 nylon, but polyurethanes, polyureas and the thioanalogues also may be used.  The compositions may be obtained by melt blending or by the aid of solvents, e.g. methanol, formic acid or in particular water.  Conveniently the poly (N-vinyl amide) may be added to the condensation polymer forming reactants before or during the condensation reaction, as is illustrated in the examples. Optional composition ingredients are polystyrene, titanium dioxide, manganous hypophosphite (light stabilizer) and antioxidants such as sodium phenyl phosphinate, cupric chloride, cupric acetate, potassium iodide, sodium thiosulphate, benzoquinone, diphenyl-p-phenylene diamine, pyrogallol and sodium iodide.

Title: Method of entering information into a memory device and device for performing the method
IPC: G06F11/16
Filed: 1961-04-06
Abstract: 960,169. Digital data storage. SVENSKA RELAFABRIKEN A.B.N. A.B. April 6, 1961 [April 14, 1960], No. 12348/61. Heading G4C. In a method of and arrangement for transferring data from a register to a cyclically operating store, such as a magnetic drum, the data is entered in the store commencing with the most significant bit and non-significant bits in positions of higher order, such as zeros, are not entered. As shown, Fig. 1, data is transferred from a register R to a magnetic drum MT, the register being scanned by a scanner A before the transfer takes place to ascertain the highest significant digit. The register R may be a contact bank in a book-keeping machine. As shown in detail in Fig. 4, the attainment of equality between the desired address of a drum sector and the drum sector addresses read from the drum MT, causes a pulse P to be applied to trigger D which changes over to enable a gate E which commences to pass clock pulses S from a timing track on the drum to step on a three stage binary counter X 1 , X 2 , X 3  the outputs of which are decoded at F to cause pulses to be applied successively to leads p 0 ..., p 7  connected to the respective stages of the register R. The stages of the register are thus scanned successively, commencing with the most significant, scanning continuing until a significant digit, as represented by the connection of a p lead to a q lead q 0  - q 11 , causes an output on a q lead to activate an "or" gate C and reset the trigger D thereby cutting off the supply of pulses to the counter X 1 -X 3 , which remains unchanged until the data in the register R is to be entered on the drum. When the entering operation begins, a five step counter T 1 , T 2 , T 3 , Fig. 1, is stepped on by the drum clock pulses, the counter outputs being decoded and fed to a distributer H whose inputs are connected to triggers I 1 -I 4  supplied with the output of a decoder B connected to the leads q 0 -q 11  of the register R so that the digits stored in the register R are successively read out in binary coded form to the triggers I 1 -I 4 , the distributer H serving to serialise the data and add a parity check bit derived from a further trigger P 1  before entry of the data on the drum MT. A circuit is also described (Fig. 2, not shown), for reading data from the drum and converting it from serial to serial-parallel form to actuate digit or machine function keys in a book-keeping machine. The register R and drum MT may be read simultaneously, the outputs being compared (Fig. 3, not shown) in a comparator which actuates an alarm if there is any inequality between the data.
