Title: Improvements in or relating to machinery or apparatus for effecting interchange of heat
IPC: A23L3/20
Filed: 1923-07-18
Abstract: 225,109. Seligman, R. July 18, 1923. Sterilizing milk &c.- Plates with facial ribs and grooves adapted when assembled to furnish inter-plate zig-zag channels for the passage of the heat-exchanging fluids, as described in Specification 223,033, [Class 64 (iii), Surface apparatus &c.], are arranged in an apparatus so that the operations of heating or cooling a fluid, or both, are simultaneous or successive and may be conducted in stages or regeneratively. In the example shown in the Figure, the apparatus comprises three sections, a regenerative section being interposed between a cooling and a heating section. Cold milk, for example, to be heated flows to the regenerative section at r, wherein it is preheated by hot milk admitted at s from a hot milk holder, the warmed milk passing out at r<1> to a filter if desired and thence to the heating section at u into which hot water is admitted at t and emerges at t<1>. Heated milk from this section flows out at u<1> to a holder and thence to the regenerative section at s and by way of s' to the cooling section emerging at s<2> cooled by brine passing from v to v<1>. The filtering may be effected in a filter plate assembled in the apparatus. In a modification, the regenerative operation may be effected indirectly through the medium of water warmed by the hot milk and used to preheat the cold milk. Communication between sections may be arranged by way of ports in the plates, and removable plugs may be used to varv the method of passage. Thus, heating might be effected with parallel flow through several plates followed by cooling with series flow.

Abstract: 339,215. M³ller Akt.-Ges., C. H. F. March 9, 1929, [Convention date]. R÷ntgen-ray apparatus. - For controlling the exposures in X-ray photography a raysensitive cell connected to a device for indicating its charge is arranged on the opposite side of the object being photographed to the source of X-rays. The exposure is given for the time required for the indicating device to reach the value at which the photographic plate exhibits the optimum ground blackening and which is constant for the type of plate used. Where several objects of different permeability to the rays are to be photographed together, a cell of sufficient size to be simultaneously affected by rays traversing each of the objects is used, or the cell may be moved during the exposure. A cassette incorporating a cell for use in the process comprises a frame 30 covered in front by a sheet of aluminium 31 behind which are placed reinforcing foils 32 enclosing the sensitive film 33. A lead plate 36, having a window 38 behind which is a shell 41 of material opaque to the rays, containing the cell 4a, is fitted in the back of the frame 30. In a modification, the shell 41 is mounted on a lead slide moving in a groove in the plate 36. The cell mav also be used to determine the time of exposure, and be replaced by the plate during the exposure itself.

Abstract: 1,133,041. Moulding fibre-resin strips. KOPPERS CO. Inc. 25 Feb., 1966 [25 Feb., 1965], No. 8507/66. Heading B5A. In a process in which a fibre-resin strip and a carrier strip of e.g. metal are drawn through a heated forming passage and the used fibreresin strip thus formed separated from the carrier strip, the edges of the carrier strip, which is wider than the forming passage, run in slots located in each side wall of the forming passage. In this way wear upon the material shaping surfaces of the forming passage by the edges of the carrier strip is obviated and a clean edged strip is produced. In the described embodiment a central carrier strip 12 sandwiched between outer fibre-resin strips 10a ,10b is pulled through a heated die by a suitable caterpillar puller mechanism, the fibre-resin strips being separated from the carrier strip after passage through the puller mechanism. The die comprises top and bottom parts 6a, 6b bolted together, the parts being separated by blocks 18 and shims 19 so as to form a passage having slots in its side walls. Shims 19 are replaceable so that strips of various thicknesses may be produced. A succession of carrier strips may be used the leading end of each strip overlapping the trailing end of the one before which is of reduced width so that only one thickness of strip passes through the slots with the forming passage (see Figs. 3 and 4, not shown). Alternatively a long single strip may be used the end of which is of reduced width.

Abstract: 194,160. Lloyd, N. M. March 28, 1922. Golf-practising appliances.-Relates to registering and indicating devices for captive ball games, of the kind in which a ball is connected to a cord wound upon spring-drum which, when the ball is driven for example with a golf club. operates a pointer which moves over a scale, the drum returning to its initial position and rewinding the cord thereon, and consists in connecting the drum with the mechanism for operating the pointer in such a manner that movement of the drum in one direction only is transmitted to the mechanism, so that the results of successive drives may be totalled on the scale. The ball is attached to a cord wound upon a spring-drum 3, Fig. 4, which carries a wormshaft 8 engaging with a worm-wheel mounted freely upon a spindle 10, supported on a bracket 11 secured to the housing. The shaft 10 is rotated in one direction only by the drum through a ratchet wheel, which is integral with a sleeve 12 on the worm-wheel and coacts with a pawl carried in a sleeve 15 secured to the shaft; rotation of the shaft in the opposite direction during the return motion of the drum is prevented by a ratchet-wheel 16 and a pawl 17 secured to the shaft and to the bracket 11 respectively. The shaft carries a slidable pinion 18 which can be adjusted by mechanism operated by a handle 32 to engage with either of the toothed wheels 19, 20, which are connected to pointers 22, 25 respectively carrying miniature golf balls adapted to move in a slot in the scale 28, Fig. 3, which is graduated to indicate the yardage of a drive and marked with representations of tees, bunkers, and greens. The handle can be moved against either of two stops 33, 34 coloured, for example, blue and red and secured to the housing. The balls are coloured to correspond with the stops. The scale is supported by a casing having a transport top, and the device is secured to the ground bv means of the base 53. In use, the handle is moved against one of the stops for example the red stop, in which case the pointer carrying the red ball will be in operative connection with the spindle 10 and one of the players drives the ball attached to the drum so as to move the red ball over the scale. The handle is then placed against the blue stop and the next player drives, the accumualtive effects of successive drives being registered on the scale. When the pointers reach the "greens" on the scale, the holes may be played on the usual putting green. The pointers can be brought back to their initial positions by means of the spindles 46, 47.
