Title: Toy motor car circuits
IPC: A63H18/04
Filed: 1976-09-14
Abstract: 1509471 Toy motor car tracks MASUDAYA TOY CO Ltd 14 Sept 1976 [19 Sept 1975] 38062/76 Heading A6S A toy motor car track is inclined and connected between the top and bottom of a lift tower so that a toy motor car can travel freely under gravity down the track to its bottom end, enter a lift in the tower, and be raised by fan driven wind power acting on the lift to the top end of the track. As shown, an inclined track 3 for a single toy car connects between the top and bottom of a lift tower 5 containing a lift 13. A toy car 1 placed on the bottom of the track 13 is prevented from entering the lift by a spring biassed stop 21. Depressing a knob 25 outside a base frame 4 carrying the tower 5 lowers the stop 21 and releases the car 1, which runs forward through a door 18 pivoted at its top edge into the lift 13. A switch (not shown) is closed to connect battery cells 9 to an electric motor 8 driving a fan 6. Air is pumped by the fan 6 through an opening 11 to the lift tower 5 and raises the lift 13. The door 18 acts as a check valve, preventing escape of the pumped air. At the top of the tower 5, the lift 13 engages slops 26, and the toy car runs out onto the top of the inclined track 3. As a modification two lift towers 5 may be arranged side - by - side with their inclined tracks 3 forming a single, double path track so that two cars may be raced against each other. If the toy car 1 accidentally falls to the bottom of the lift shaft, it can be removed through a sliding door 28.

Title: Sutures and methods of making same
Inventor: KURTZ LEONARD DAVID
IPC: A61L17/14
Filed: 1966-08-25
Abstract: 1,148,466. Filamentary strands. L. D. KURTZ. 25 Aug., 1966, No. 38098/66. Heading B5B. [Also in Divisions A5 and D1] A suture comprises a non-absorbable polyfilamentous strand having tissue-inert solid particulate polytetrafluoroethylene (P.T.F.E.) incorporated in the interstices thereof to an extent sufficient to fill the dead air spaces therein whereby the polyfilament is given properties of a monofilament. The polyfilamentous strand preferably is made from hydrophobic material, for example a synthetic material such as a polyester, a polyolefin or a polyamide. The impregnated suture is obtained by treating the polyfilamentous suture strand with a dispersion or suspension of tissue-inert solid particles of P.T.F.E. in a fluid carrier, the particles having a size sufficiently small to enter into and be retained within the interstices of the polyfilament thereby to fill the dead spaces of the polyfilament, and thereafter removing the fluid carrier from the impregnated suture. The dispersion or suspension preferably is an aqueous dispersion, for example a saturated aqueous dispersion; the particles of P.T.F.E. preferably have an average size of not more than 1 micron, for example of 0À2 micron. When the strand is hydrophobic, it may include from 5 to 30%, preferably 5 to 20%, based on the weight of the untreated strand, of particles of P.T.F.E.; a polyester strand preferably includes from 8 to 14% of P.T.F.E. particles. As exemplified, a polyethylene terephthalate suture is impregnated with particles of P.T.F.E., dried and hotstretched (at a platen temperature of 450‹ F.) by 40% based on its original length. The sutures may be sterilized by known techniques, for example by electromagnetic radiation or by autoclave ethylene oxide.

Title: Improvements in or relating to thermostats and thermostatic switches
IPC: H01H37/02
Filed: 1957-12-10
Abstract: 875,632. Thermal switches; switch contacts. TEXAS INSTRUMENTS Inc. Dec. 10, 1957 [April 24, 1957], No. 38436/57. Class 38 (5). [Also in Groups XIII and XXII] A temperature-responsive actuating-element such as a snap-acting bimetal 11 is mounted, as by welding, on a post 9 which is a press fit in a hole 7, the post or hole or both having a surface of soft metal 27 such as tin, lead, cadmium, zinc, aluminium or silver which is smeared by the press action. The metal-coated surface may be first roughened, e.g. the steel post 9 may have longitudinal grooves 25 or grid-type knurling. Pressing of the grooved post into position causes distortion of the hole 7 as shown in Fig. 5 and the pressing is done in stages with intermediate testing of the operating temperature so that the final pressing fixes the post to give the position for the desired operating temperature. In a switch, in an unheated condition, a contact on the bimetal 11 engages a metal strip which constitutes one terminal of the switch and which is secured, on an insulating strip by a rivet passing through an insulating bushing, to a pressed steel base 3. The base is formed with the hole 7 and with the other switch terminal 23. In a modification, the base is formed of moulded insulation with embedded metal terminals, one of which has the hole for the post and the other of which bears a fixed contact.

Title: Improvements in or relating to translating stored data into a code
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04L12/54
Filed: 1956-12-18
Abstract: 833,369. Magnetic counting-apparatus; datastorage apparatus. STANDARD TELEPHONES & CABLES Ltd. Dec. 18, 1956, No. 38559/56. Class 106 (1).. [Also in Group XL (b)] In code-translating equipment comprising a first store in which data is stored and a second store in which the code is stored, the stores comprising ferro-electric or ferro-magnetic cells, the cells in the first store are coupled to groups of cells in the second store, at least one group being coupled to two or more cells, and the coupling means are cyclically scanned in a predetermined sequence The apparatus described. comprises 5 columns 31-35 (only one shown) of ferror-magnetic storage cells, which may be formed by individual toroids or by holes in ferro-magnetic blocks, and is used for reading out, digit by digit, in a 5-unit telegraphic code, the amount registered in a single column decimal counter 21 as described in Specification 833,368. The rows of 5 cells, from bottom to top, are set to represent the coded form of the decimal digits 0, 1 ... 9 respectively and are connected to corresponding row wires for each counter denomination as indicated. Thus the rows of cells are scanned sequentially with the corresponding counter cells, by half-read and half-write pulses 1W1, 1W2; the pulses are applied also to column wires via amplifiers 31W-35W. Any " 1 "- indicating output obtained through a column wire or a separate output wire at amplifier 31R-35R sets bi-stable trigger 31F-35F to " 1 "; output 31f1-35f1 opens gate 3G1 to cause the " 1 " to be re-written, the triggers being reset via 3G2 before read-out of the next row. When an output is obtained from counter read-out amplifier 21R, triggers 30F, 36F are set to "1," to prepare for stepping 3-stage counter 3C and to condition gates 3G4, 3G5, 3G6 respectively. Such gates receive the " 1 " outputs of 31F-35F and are controlled by the successive stages of 3C so that the coded representations of the units, tens and hundreds digits in counter 21 are transferred to triggers 41F-45F, 51F-55F and 61F-65F respectively. The coded digits may subsequently be transferred to some other storage medium, e.g. a shift register or magnetic drum. If it is required to translate the number on the counter into more than one code, additional arrays of coding storage cells like 31-35 with associated circuitry may be provided.
