Abstract: 868,981. Pound boards. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug. 24, 1959 [Aug. 15, 1958], No. 26319/58. Class 113. A corrugated metal pound board comprises parallel channels of equal width and of equal depth, measured from the centre-line A, which are disposed alternately on either side of the centre-line. Each channel has a flat web 1 terminating on both sides in flanges 2 which are disposed at equal obtuse angles of their respective webs and radiused to facilitate clearing of the board. All the webs are parallel to the centre-line A and the extreme flanges 3 of the board extend in opposite directions from their respective webs. The intermediate flanges 2 are curved at all points, there being a point of inflexion at a point intermediate between the two webs.

Title: Means for damping vibrations of rotating bodies
IPC: B04B9/14
Filed: 1951-11-09
Abstract: 721,226. Vibration dampers. AMERICAN LAUNDRY MACHINERY CO. Nov. 9, 1951, No. 26320/51. Class 108 (3). [Also in Groups 11 and XXIX] A radial vibration damper 21 rotating concentrically with a rotary body 12 is driven by means of a constant ratio driving connection from a shaft 33, and the body is driven from the shaft by means of a slip clutch 35. A member 25 carrying the damper is driven by a belt 30 from the shaft which is the shaft of an electric motor 31. The damper is resiliently connected to the member by helical springs 23, and has a rubber ring 26 bearing on the member. The body shown is a hydro-extractor basket which is fixed to a shaft 13 rotating in a flexibly supported bearing 14. Excess tilting of the basket is prevented by a buffer 28 on the member 25. The shaft 13 has a pulley 17 driven by a belt 18 and a pulley 41 integral with the casing of the slip clutch. The clutch is driven by the shaft 33, the arrangement being such that on starting the motor the damper reaches maximum rotational speed before the basket, and on shutting-off current to the motor and applying a brake 19a to the pulley on the basket shaft, the damper continues rotation after the basket has stopped.

Title: New or improved egg-boiling appliance
IPC: A47J29/00
Filed: 1927-10-08
Abstract: 299,596. Bond, E., and Sumerling & Co., Ltd. Oct. 8, 1927. Egg-cooking apparatus. - In an egg-boiler, a conveyer is arranged to immerse the eggs in boiling water, convey them slowly through the water during the cooking period and to deliver the eggs when cooked by continuing the conveying motion out of the water. As shown in Fig. 1, the apparatus comprises a boiler 1 having a false perforated bottom 19 of arcuate shape to correspond with the path of the vanes 13 on a rotating disc 11. A shoot 15 is hinged at 16 to the boiler 1 and is angularly adjusted by a quadrant and clamping screw 17. The eggs roll down the shoot 15 and fall into the pockets formed between the vanes 13 which have inclined flanges 18 at their rear faces to prevent the eggs from passing too readily into the pockets with the danger of the following egg being jammed by the following vane. The flanges 18 may be replaced by rollers. The cooked eggs are delivered on to a shoot 21 having a removable stop pin 23, or delivery may be made into a padded receptacle. The disc 11 is mounted on and connected to a shaft 3, rotated by a motor, by a sleeve 9 having a screw 10 which is adjustable to regulate the friction drive between the sleeve 9 and the shaft 3. A non-adjustable friction drive between the sleeve and shaft may, however, be provided. Alternatively, the friction drive may be interposed in the gearing between the motor and the shaft 3. To permit eggs being removed from the boiler before the normal cooking period has expired, the casing 1 is provided with a lateral compartment 24 communicating with the main boiler through an aperture normally closed by a shutter which may be formed integrally with the lid of the compartment. A spoon may be inserted through the aperture and an egg removed from the pockets of the conveyer. If hard boiled eggs are required, eggs may be removed from the shoot 21 and placed in the compartment 24 for further cooking. A heater is enclosed in a base portion 27, and a removable cover 28 covers the conveyer. A clockwork driving motor may be used. The conveyer may be designed for a single series of eggs, or each pocket may hold a row of eggs in which case the conveyer would accommodate a number of series of eggs, the feed and delivery shoots being formed accordingly. Alternatively, the boiler is divided into compartments by partition walls, each compartment holding a separate rotary conveyer. The conveyers are mounted on a common shaft and the time periods in the compartments are regulated by overflow holes which control the water levels in the various compartments. In a modification, the time periods are altered by mounting the drums concentrically on shafts arranged within one another, and rotating the drums at different speeds. The drum vanes may be inclined from a true radial position to assist in the delivery of the eggs on to the shoot 21. The shoot 15 may be replaced by a hopper or an endless conveyer.

Title: Tomographic imaging device
IPC: G01T1/29
Filed: 1971-04-19
Abstract: 1294290 Tomographic imaging NUCLEARCHICAGO CORP 19 April 1971 [13 April 1970/ 26750/71 Heading H4D A tomographic imaging device includes a stationary planar radiation sensitive transducer producing co-ordinates of the received quanta of radiation, means for supporting an object under investigation, shield means between the transducer and support defining a radiation acceptance direction for the transducer and means for synchronously moving the support and shield means in such a way as to provide stationary images of radiation from points on a reference plane and predetermined patterns of images from points on other planes. The detector outputs yield directly the distribution of radionuclides throughout the reference plane and may be processed to provide the distribution across the other planes. Collimator 23, Fig. 1, comprises a bad disc pierced by numerous channels angled at #-20 degrees to the vertical, the collimator is rotated and synchronously therewith the "floating" table 41 supporting the object 10 is processed about a radius R= (db + c) tan #.Thus gamma-ray sources A, B, C in the plane parallel to the transducer 31 containing point B produce focused points as the collimator rotates. Points in other planes, e.g. A, C, however describe circles (Figs. 2-4, not shown). The transducer 31 may thus be focused on any reference plane by raising or lowering table 41 or varying the precession radius R. The complete apparatus, Fig. 5, comprises a "floating" X-ray table 41 supporting the patient and a detector unit 30 carrying the collimator and containing the transducer, e.g. a thallium activated sodium iodide crystal and a detector, e.g. a scintillation camera as described in Specification 3,011,057. This produces Cartesian coordinates representing each detected scintillation. Signals representing the rotation of the table 41 of the collimator are fed with the detector outputs to a computer which derives therefrom distributions of the radionuclides in any selected plane throughout the object 10. Four cross-sections at various levels may be indicated sequentially on the C.R.T. display 110 which is photographed by a time-lapse camera.

A rectangular area 4 on the top of the wafer is coated with indium, nickel and a second indium coating. Soldered through the top of the housing is a flat copper strip 5. The lower face 10 of the looped portion is coated with indium so that when the two parts of the housing are brought together and slightly rotated, the conductor is able to give slightly and a cold weld is formed between the conductor and the wafer. Part 8 of the housing is of glass and flange 9 on the upper part is sealed or welded inside flange 3 on the lower. The assembly is exhausted through tube 7. In a modification (Fig. 4, not shown), a tube through the centre of the housing serves both to exhaust the housing and to support a flexible loop cold-welded to the germanium.
