Title: Improvements in or relating to machines for punching records such as record cards
Inventor: THOMAS ARTHUR
IPC: H04L15/10
Filed: 1953-03-31
Abstract: 741,746. Selective punching machines. POWERS - SAMAS ACCOUNTING MACHINES, Ltd. Feb. 18, 1954 [March 31, 1953], No. 8972/53. Class 31 (2). [Also in Group XXIV] A machine for recording data in the form of perforations by punches which are conditioned by signals initiated from a keyboard consisting of manually-operated keys 1 each representative of a character to be recorded, comprises normally-inactive selector means movable by the keys to an active condition to determine the signal or signals to be transmitted on the operation of any one key, a bail 19 supported for reciprocation and co-operation with an active selector means to cause the latter to operatively engage the signal transmitting means, a one-revolution clutch for operating the bail, and a latch device arranged to set the clutch into operation upon the actuation of any key and to disengage it after one revolution irrespective of whether or not the actuated key is restored to its inactive condition. The keys 1 are disposed in a keyboard similar to that of a typewriter and each is arranged so that when depressed it acts through a bell-crank 23 to slide leftwards in Fig. 1 a link 21 and thereby swing an interponent 17 so that a notch 18 in the bar engages over the bail 19 which is common to all the interponents ; each interponent is pivoted on a spring-supported lever 13 and normally urged away from the bail by a spring 20. The downward movement of the bail, which occurs whenever a key is depressed, then lowers the engaged interponent and rocks the corresponding operating lever 13 into engagement with the upstanding portions of one or more of a set of code bars 12 according to the prescribed code. Each code bar constitutes one link of a parallel linkage 4, 9, 10, 12 so that when actuated by an interponent it acts through a plunger 3 upon a flexible cable 2 for transmitting a signal for controlling the corresponding set bar of the punching machine. The bail is operated from eccentrics 37 on a shaft 38 which is driven through the onerevolution clutch whenever a key is depressed. The key when depressed acts through its link 21 upon a pivoted bail 58, Fig. 1, common to all the keys, and then through a link 57 and trip lever 55 to release latch members 47, 48, Fig. 2, which thereby permit a pawl 43 pivoted on the clutch disc 40 to engage a ratchet-wheel 45 on a power-driven shaft and so actuate the clutch ; the latch members trip the pawl after one revolution of the clutch and so disengage it. A space operation of the punching machine is controlled by a bar 67 through a flexible cable, and punching and skip operations are each controlled by a key which operates the clutchengaging linkage 57, 58 and, through interponents, an operating bar 13 acting directly upon a flexible cable. Instead of the plungers 3 operating flexible cables for setting the punches, they may actuate electrical contacts for controlling the set bars electrically.

Abstract: 645,902. Magnetic and electric tests. RADIO CORPORATION OF AMERICA. April 1, 1948, Nos. 9246 and 9247. Convention dates, April 19, 1947, and Feb. 3, 1948. [Class 37] The invention relates to apparatus for locating magnetic or conducting materials comprising two magnetically-coupled circuits, normally not mutually inductive, whose balance condition is upset by the presence of the magnetic or conducting material, and consists of means for neutralizing stray voltages in the coil systems by coupling the primary and secondary windings through two cores whose magnetic properties are such as to give induced voltages in quadrature, so that the rectangular components of any unrequired unbalance voltage may be balanced out independently. The secondary, or, as shown (Fig. 1c), the primary, may consist of two similar opposed windings 15, 17 connected in parallel or in series. Two adjustable metal slugs 49, 51, Figs. 6, 7, are introduced between the primaries 15, 17 and the secondary 19, consisting of such metals as to induce voltages, in quadrature into the secondary, the magnitude of such voltages being adjusted by knobs 41, 47 through worms 37, 43 and gear-wheels 33, 35, altering the position of each slug with respect to the coils. A fabric belt 31 between the primary and secondary windings carries the articles to be inspected. A list of metals and their properties (Fig. 8, not shown) enables appropriate choice of metals for the slugs to be made.

The casing is provided with a slot 5 registering with a corresponding slot in two sleeves 6, 13 which are secured in place by a screw 9 serving also to retain the pocket-clip 7. The rear end of the sleeve 13 is formed with a number of teeth 26. The springs 14 are each provided with a head 4 adapted to pass through the slots in the sleeves 6, 13, and casing, and are formed with a bent portion 18 which, when the lead holders are in projected position, spring outwardly and engage under the end of the sleeve 13. When the lead holders are withdrawn, the head 24 can be rotated to enable a desired lead to be selected, the heads 4 snapping over the teeth 26 under the influence of a spring 27 on the end of the sleeve 20.

Title: Improvements in or relating to the manufacture of coating compositions and to the production of resistant coatings
IPC: C09D115/00
Filed: 1932-04-04
Abstract: A coating-composition is prepared by disaggregating unvulcanized rubber by heating in the presence of oxygen, or gases, e.g. air containing oxygen, and mixing the viscous product with sulphur and if desired with accelerators, fillers and other p  compounding ingredients.  The composition is applied to surfaces of metals, wood, concrete, stoneware &c. by painting, spraying or dipping and is then vulcanized, e.g. by hot air.  In an example unvulcanized rubber is melted in a suitable vessel in the presence of air at a slowly rising temperature.  At 100 DEG  C. the mass becomes a thin liquid, and heating is continued for several hours and/or the temperature is raised to about 250 DEG  C.  After the desired viscosity is obtained the mass is cooled to 30-80 DEG  C. and sulphur, preferably in an amount exceeding 30 per cent. by weight of the rubber, is worked in and also if desired other compounding ingredients.
