Title: Method and apparatus for producing foam rubber slabs or contoured pads
Filed: 1955-03-24
Abstract: 782,453. Coating webs; coated fabrics; laminates. NATIONAL AUTOMOTIVE FIBRES, Inc. March 24, 1955 [Jan. 17, 1955] No. 8645/55. Class 140. In a method of making contoured foam rubber slabs the upper surface of uncured foam rubber is continuously shaped to a surface pattern departing substantially from the horizontal by advancing it beneath a correspondingly contoured doctor blade on a flat horizontally moving support such as a woven fabric and immediately thereafter the contoured foam is passed over direct heating means to set the foam in the predetermined contour while resting upon and engaged solely by the support. A web of flexible backing material is unwound from a reel 14 and is passed round a series of rollers 18a-18g to form a double ply over a gauge plate 10 where it is coated with uncured latex foam from a pipe 22. The web then is passed beneath a vertically adjustable contoured doctor blade 20. The coated backing material is then passed over heating means such as steam pipes before entering a gelling oven 26. The web is carried on an endless conveyer belt 38 beneath electrodes 28 adjustably connected to high-frequency oscillators 32 then to a preheating oven 34 which is similarly supplied with electrodes but also has hot air or steam heat. The web then is passed on an endless conveyer 46 through a hot air or steam heated curing oven 44. The conveyer 38 may be made of neoprene and the conveyer 46 of flexible wire mesh. Compressible displacement members may be placed in the foam rubber, e.g. in the form of parallel strips cut from a web of bonded alpha cellulose fibres. The web of bonded fibrous material is passed from a reel beneath a cutter 82 to produce strips 84 which are passed through a twisting and spreading frame 90 to space the strips laterally. The strips are then passed with the backing material over the gauge plate 10 to receive the coating. The backing material may comprise woven fabric, plastic film or paper.

IPC: B65H33/12
Filed: 1945-04-09
Abstract: 595,280. Delivery apparatus for printing &c. machines. HOE & CO., Ltd., R., and SKINNER, C. H. April 9, 1945, No. 8678. [Class 100 (i)] Apparatus for delivering printed or like products comprises an S-fly depositing the products on a conveyer in overlapping formation, and mechanism adapted at " count " intervals to hold back from the conveyer for a period the leading products of a batch and at the same time to accelerate the conveyer, so that the batches are separated. As shown, printed products P issuing from folding rollers 2, 3, are delivered by a rotary-fly 6 to a conveyer system 8, 18. Adjacent to the fly are rotating discs 11 which strip the products from the fly. Rotatably mounted on the discs 11 are spindles 10 carrying fingers 9 the tips of which are caused by gearing - 101, 10 10<3>, Fig. 1 to follow a path X, Fig. 4, so as at intervals to support the leading edges of the products leaving the fly thus displacing such products and separating the products delivered to the conveyer into batches of predetermined numbers. Co-operating with 'the fingers 9 to temporarily support the displaced products are blades 14 which may be pivoted and operated in synchronism, with the fingers by a cam 26 and links 29, 30. The gear 10<3> may be given an oscillatory motion so as to give the fingers a rapid movement as they are projected. To separate the batches, the conveyer system comprises slow moving belts 8 to which the products are delivered normally and faster moving belts 18 brought into operation during the period the parts 9, 14 are effective. For this purpose, the guide pulley 17 for the belts 8, which is normally above the run of the belts 18, is carried by a bell-crank lever 22 operated from the cam 26 so as to bring the belts 8 below the belts 18 and thus transfer the batch to the fastermoving belts. The conveyer system is carried by a frame 32, pivoted at one end to brackets 33 adjustable by screw mechanism 34 and at the other end is spring-mounted on rods 36 adjustable by screw-mechanism 39, the arrangement yielding if a jam should occur. The blades 14 may be yieldingly mounted for the same purpose.

Abstract: 1,253,873. Semi-conductor radiation detector. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 18 Feb., 1969 [19 Feb., 1968], No. 8708/69. Heading H1K. A radiation detector is made up of a plurality of trapezoidal elements 11-18 arranged to form a polygon, as shown in Fig. 2. The elements shown are each lithium-drifted germanium nipin double devices, that is they have two compensated sensitive regions each with appropriate electrodes. Alternatively the elements could be single pin lithium-drifted devices or non-drifted devices of silicon or A<SP>III</SP>B<SP>v</SP> semiconductor. If the radiation source is placed within the polygon the detector is of the " well "-type, and if opposite elements of a detector are connected to separate pre-amplifiers in coincidence it is possible to distinguish between signal components relating to the photoelectric effect and the Compton effect. In general, if separate preamplifiers are used for each device very high counting rates can be handled. A variant detector has the polygon of Fig. 2 with the addition of a known coaxial detector in the central space. The elements of the electron in Fig. 2 may be held together by an insulating or metallic strap; they may be encapsulated as a unit or may be individually encapsulated as shown in Fig. 4. The nipin element is mounted on PTFE blocks 25, 26, 27 within an evacuated or gas-filled aluminium housing 19. Connection between the p-type zone 6 and the housing is established by alumising the surface of blocks 27. Pressure contact to n-type source 9 is made by spring 48. Contact to the other n-type zone 10 is made by an insulated lead not seen in Fig. 4. Fig. 3 (not shown) gives details of the cold-welded end plate of the housing which is dished to allow for dimensional changes when the device is cooled to liquid nitrogen temperatures. Mention is made of the easy replacement of individual elements and of the possibility of re-drifting elements during their operational life.
