Title: An improved method of, and means for, handling biscuits
Inventor: PAGE ALFRED CORNELIUS
IPC: B65B23/12
Filed: 1948-10-21
Abstract: 670,590. Feeding biscuits to hoppers. WRIGHT'S BISCUITS, Ltd. July 21, 1949. [Oct. 21, 1948] No. 27343/48. Class 78 (i). A method (Fig. 1) of automatically feeding biscuits from a stacking machine to a vertically disposed hopper 16 comprises confining the biscuits between side guides 11 and causing the biscuits, on edge between the guides, to push one another along from behind over a band or table 15 which is curved over at right angles in the vertical plane so that the biscuits are turned from a vertical position to a horizontal position, said band or table terminating at the entrance to the hopper. Fig. 1. Biscuits 10 are fed from the stacking machine (not shown) between side guides 11 and upon table 13 by endless conveyer 12, and push each other up sleeve 14 and then between flexible steel bands 15 and 17 so that they pass into hopper 16 in flat position whence they are discharged by reciprocating device 23. Figs. 2 and 3. The flexible bands 15, 17 are enclosed within fixed guides 18, 19 which are spaced apart by pillars 20, guides 22 thereon serving as side guides for the biscuits and slots 21 permitting substitution of different pillars to vary the width apart of guides 18, 19. As shown, several rows of biscuits are guided side by side. Fig. 4. The bands 15, 17 are fixed at one end to hopper 6 and are movable at the other end (as in Fig. 4) so that when the feed is increased the bands expand upwards. To prevent excessive feed, band 17 is bent round to form a lug 24 which, when the band 17 flexes upwards, is forced down to enter a slot in sleeve 14 and thus prevent further feed till the excess of biscuits between the bands has been discharged. Figs. 5 and 6. When there is too small a feed, the bands 15, 17 tend to drop, and this tendency is utilised to block hopper 6 and to prevent discharge of biscuits therefrom, the movement depressing rod 25 against spring 26 and through linkage 33, 34, 35, 36 moving clamping plates 37 inwards within hopper 6 to stop the downward movement of the biscuits. The rod 25 is kept down by latch 29 engaging detent 30 in the said rod, and latch 29 is operated by reciprocating discharge block 23. This ensures that no biscuits are discharged from hopper 6 until there is a sufficiency of biscuits between the bends and until the said blade is moved to the left as shown (to engage latch 29) to prevent the blade breaking any biscuits. Specifications 670,560, [Group II], and 670,599 are referred to.

Abstract: 1462901 Transverse-flow fans TOYOTA CHUO KENKYUSHO KK 20 June 1974 [26 June 1973] 27357/74 Heading F1C [Also in Division F4]  In a rotary heat exchanger for heat exchange between a liquid and air having a rotor 6 comprising a plurality of a spaced apart hollow annular elements 17 coaxially disposed in planes extending perpendicularly to the rotor axis with annular arrangements of curved blades 16 extending between and connected to adjacent elements 17, liquid is supplied to and withdrawn from the annular elements 17 by means of diametrically opposed distribution and collection ducts 18 and 19. Liquid enters a chamber 7 at one end of the rotor via a stationary pipe 10 and a plurality of radially extending distribution passages 10A. The chamber 7, which includes a plurality of straight or curved blades 11 arranged to rotate with the rotor, communicates with the distribution duct 18 which in turn communicates with the annular elements 17 via openings 17B; liquid leaving the elements 17 via openings 17C and collected in duct 19 is led into a chamber 8 at the other end of the rotor and is discharged therefrom by way of a stationary outlet guide structure 13 and a pipe 12. Preferably the guide structure 13 is in the form of a spider comprising a series of arcuate passages leading inwardly from tangentially disposed inlet ports 13A towards the pipe 12. In an alternative embodiment Fig. 5 (not shown) the chambers 7 and 8 are located at the same end of the rotor. In addition to inducing and guiding a flow of air through the rotor, the blades 16 also serve as heattransfer fins and may be made from corrugated strip material see Fig. 11 (not shown); louver segments (16A), Figs. 12a and 12b (not shown) may be stamped and bent out from the surface of the corrugated strip and arranged along arcuate or suitably curved lines extending in the direction of rotation of the rotor. The rotor 6 is located in a passage 3 defined by casing members 1 and 2, with air entering through an inlet 4 and being discharged through an outlet 5. In order to maintain a constant air delivery temperature the rate of air-flow through the rotor can be controlled by a throttle plate 22 pivotable on a shaft 24. The angular position of a plate 21 pivotable on shaft 23 controls the position of the Rankine's vortex 20 within the rotor.

Title: Radiation filters
Inventor: BAYNHAM ALEXANDER CHRISTOPHER
IPC: H01P1/215
Filed: 1968-06-10
Abstract: 1,237,708. Fillers. MINISTER OF TECHNOLOGY. 27 Aug., 1969 [10 June, 1968], No. 27398/68. Heading, H1W; A filter comprises means for transmitting a circularly-polarized microwave through layers of material, one of which has a permittivity or permeability dependent upon the strength of an axial magnetic field. The filter is basically of the type in which a frequency-dependent interference effect is produced as a result of reflection at spaced discontinuities. As shown, a circular waveguide 11 is loaded.with dielectric material 7 in which are embedded layers 1, 3 of a semi-conductive material, e.g. intrinsic indium antimonide, a variable magnetic field being applied normal to these layers by means of horseshoe magnets 13, 15 and a solenoid 21. In addition, the waveguide contains half-wave plates 27, 29 for converting a linearly polarized. (L.P.) to a circularly polarized (C.P.) wave and vice versa. Unwanted components of the L.P. waves are absorbed by resistive elements 25, 31. It can be shown that the tensor permittivity of the semi-conductor layers is frequency dependent and hence the velocity of a C.P. wave therein depends both upon the frequency of the wave and the magnetic field. The frequency response of the filter may therefore be varied by means of the field. The layers may be flanked. by two further layers of ferrite which may contribute to the variable filtering action since it has a permeability dependent upon the magnetic field. The (outer) layers of ferrite 35, 37, Fig. 4, may form a pair of permanent magnets and may be joined by a soft-iron tube 39 which completes the magnetic circuit. The tube may be silvered inside to form a waveguide.
