Title: Improvements in process of manufacturing brushes
IPC: A46D1/00
Filed: 1925-09-23
Abstract: 240,822. Withycombe, R. M. Oct. 2, 1924, [Convention date]. Filamentous rubber.-A process of making a filamentous rubber brush consists in causing a strip of rubber to adhere to a relatively non-elastic backing, thereafter slitting the strip. As shown in Fig. 2, a rubber strip 1 is secured by adhesive to a backing 2 of cardboard or other material and slits 4 and 5 are made in the rubber. The strip when cut is removed from the backing to form two strips, each adapted to be rolled to form a brush. In order that the brush in use may be capable of holding a considerable quantity of liquid the filamentous part of the strip may be given a curved set. This may be done by coating one side of the strip with linseed oil and allowing it to dry before attaching it to the backing. In another method the strip is stretched upon a saddle-shaped form, having been coated with a composition to produce unequal tension on opposite sides of the strip. In a further method the rubber strip, prior to being slit, is vulcanized upon a suitably curved form, which may be the backing itself.

Title: Improvements in or relating to machines for inspecting the dimensions of work-pieces
IPC: B07C5/08
Filed: 1944-12-01
Abstract: 587,203. Sorting-apparatus. SIGMA INSTRUMENT CO., Ltd., and BOOSEY, F. R. Dec. 1, 1944, No. 24039. [Class 106 (ii)] Sorting-apparatus comprises a primary gauging anvil for contacting the work-piece and thereby performing gauging movements which are directly mechanically communicated to an arm capable of engaging either of two electric contacts. - When the work-piece is of correct size, oversize or undersize, the arm contacts respectively, neither' contact, one contact or the other, to operate appropriate electromagnetic means for the sorting of the pieces. As illustrated diagrammatically in Fig. 1, work-pieces W are delivered successively by a rotor 10 into gauging position at such time as a cam 24 driven by the same means as the rotor 10 assumes the position shown. The anvil 8 is moved to contact the work-piece and through the anvil 2 adjusts a spring-pressed bell-crank 5 to neutral position or to touch contact 6 or 7 according to whether the work-piece is correct size, undersize or oversize, respectively. As the cam 24 rotates one step, contacts 29, 31 and 32, 33 are closed, and if the work-piece is oversize or undersize, circuit is established from source 35 through these contacts and contact 6 or 7 to an electromagnet 19 or 21 which operates a deflecting plate 12 or 13. The projections 16 or 23 close contacts 40 or 42 to maintain the electromagnet energized while the cam follower 25 opens the contacts 29, 31 on reaching the periphery of the cam 24, so that as the work-piece is released by the gauging device the position of the bell-crank 5 does not affect the circuit. The electromagnet therefore holds the appropriate deflection plate in position while the gauged work-piece is passed to the shoot 11. When the cam follower 25 reaches the low point 26 at the next gauging point, the contacts 32, 33 open to break circuit to the electromagnet and contacts 29, 31 close ready for the next gauging operation. The mechanical details are shown in Fig. 5, the bell-crank 5 and related contacts being enclosed in a device 50 carrying a gauging anvil 51 and adjustably mounted in a stock 49. A motordriven sprocket 68 is solid with a cam 66, equivalent to cam 24 of Fig. 1, which also carries three equally-spaced spring-pressed studs 62 adapted in turn to press a spring-pressed anvil 53 against the work-piece W held by a rotor 56 which is rotated with the cam 66 but is made to pause in the gauging position when the highpoints 61A of a face cam 60A, rotating with the cam 66, engage a spring-pressed rod 75 which is projected to engage a stop 78 on the rotor 56, a spring coupling 72 permitting the suspension of drive to the rotor and the subsequent acceleration when the stop 78 is released. Deflectors 86, 87 operate to deflect defective work-pieces as in Fig. 1. In addition to the magnets, there'may be signal lamps.

Filed: 1968-05-22
Abstract: 1,168,198. Detecting neutrons. UNITED STATES ATOMIC ENERGY COMMISSION. 22 May, 1968 [13 June, 1967], No. 24357/68. Heading G6P. Isotope mixture analysis, in, for example, nuclear surveillance, is effected by neutron irradiating the mixture and analysing the delayed neutron response. One embodiment employs a subcritical arrangement while in a second, a nuclear reactor is used. The absolute quantities of individual fissile and fertile species are determined directly by detector calibration. The delayed neutron yield and spectral shape are uniquely characteristic of each individual species. In the subcritical arrangement a pulsed neutron source comprises a neutron flash tube in which the reaction is:- The arrangement is suitable for the assay of PU239 or U233 in fuel elements or breeder blankets, or in the non-destructive evaluation of burn-up in irradiated fuel. Alternatively, the neutron source may be a focused plasma device, accelerator or nuclear reactor. The delayed neutron response is measured by a neutron detector followed by time analyser. The detector is a proportional counter, giving discrimination against gamma rays, and the analyser is a gated counter. In a nuclear reactor, where the isotopic composition of the fissionable material is to be analysed, the delayed neutron response may be measured after a rapid shut-down, after pulsed operation or by a measurement of the phase and magnitude of the zero power reactor transfer function in response to small, low-frequency reactivity oscillations. The least squares techniques are used to obtain the fractional delayed neutron yields from the measured data. The pulsed operation may be carried out by a "prompt burst" excursion plus a rapid shutdown of the reactor or by pulsing the shut-down system with an external neutron source. The transfer function method employs input-output cross-correlation techniques to reduce drift and background effects.
