Title: Improvements in the production of brewers' wort
Inventor: DUMMETT GEORGE ANTHONY
IPC: C12C7/06
Filed: 1957-10-17
Abstract: In producing brewers' wort by mashing a mixture of grist and liquor, the mixture is fed continuously to a duct having a transverse dimension and form selected in relation to the mixture and its rate of feed as to cause the mixture to flow as a quiescent plug through the duct, and the length of the duct is such as to ensure that the plug remains as such in the duct for a time sufficient for sensibly complete reaction during movement in the duct.  The duct may be inclined upwardly or downwardly at a gradient of the order of 1 : 50 (Figs. 1 and 2, not shown).  The continuous discharge from the duct is conveyed to a separator from which the separated sweet wort is passed continuously to the input of a continuous or batch-operating apparatus for converting the sweet wort into hopped wort and the hopped wort is passed to a fermenting stage (Figs. 3 and 4, not shown).  Suitable dimensions of the duct are disclosed.

Abstract: 1,188,704. Delivering sheets. M. D. MARTIN. 14 July, 1967 [20 Feb., 1967], No. 32502/67. Heading B8K. A sheet stacker is provided with means to move the discharge end of a sheet conveyer upwardly as the stack accumulates and then back to an initial position, there being a set of catcher fingers arranged at the said discharge end and movable to intercept sheets leaving the conveyer when the discharge end has reached a predetermined height and movable out of the intercepting position when the discharge end has been moved back to its initial position. Sheets are stacked on a pallet or delivery conveyer 6 by a conveyer mounted in a frame 2 which conveyer is adjustable in height according to the height of the stack, by a device 3. When the stack reaches a maximum height and must be removed, delivery is continued, but the sheets are intercepted by a series of parallel spaced fingers 101 slidable in guides from beneath member 31. The front corners of the intercepted sheets are supported by plates 121 which are swung into position simultaneously with fingers 101. The fingers and plates may be under pneumatic control and the movement of these members is timed with the stacker controls for raising and lowering the discharge end of the conveyer frame 2. An air cushion device 7, including a manifold 31 which is held generally parallel to the top of the stack by the turning of pivoted bracket plates 32, produces an air cushion on top of the stack and below the sheets being delivered from the frame 2. When the sheets are being intercepted by fingers 101 and plates 121 the device 7 provides an air cushion between discharged sheets and the fingers and plates.

[Also in Division G1] Cancerous animal cells are identified by scanning the cell with a beam of electromagnetic energy of a wavelength within the absorption band of nucleic acid in the cell, detecting the energy reflected or transmitted and indicating when the variations of energy intensity differ from a predetermined pattern of variation. Light from a source 7 is focussed on the cell under test on a slide 1 and the transmitted light is split by a prism 15 so that light of a wavelength absorbed by nucleic acids (2652 ) falls on a photomultiplier 25 and a wavelength absorbed by cell proteins or a stain falls on a photomultiplier 31. The slide is moved in a rectangular raster pattern and the respective outputs S 1 , S 2  from 25, 31 are differentiated, and if the difference between the derivatives R1, R2 is greater than a preset valve a signal from circuit 39 indicates that the cell is cancerous. The prism may be replaced by filters or dichroic mirrors and the slide may be fixed, and scanned by a flying spot scanner. In a modification only wavelength 2652  is used, the presence of high frequency components in the output from the photomultiplier, detected by a high pass filter indicates that the cell is normal. Their absence indicates a cancerous cell.

Abstract: 1,019,291. Electrophotographic apparatus. RANK-XEROX Ltd. Aug. 27, 1962 [Aug. 30, 1961], No. 32786/62. Heading G2H. A xerographic apparatus comprising an electrostatic charging station for charging a photoconductive surface, a radiation projection station for forming a latent electrostatic image of an original only along a series of parallel lines on the charged recording surface and a developing station for developing the latent image on the photoconductive recording surface, the recording surface being successively passed through the stations. Normally a grid of parallel wires stretched across a frame is either placed in the path of the light from the original or the charged surface is exposed through such a grid before or during exposure to an original. As shown, a photoconductive layer on drum 10 is uniformly charged by corona discharge 13 and exposed to the microfilm projector 14, which contains a lens turret assembly 16, microfilm 17, lamp 21 and condenser lens 22, the film being moved synchronously with the drum and the image beam passing through shaft 24, variable width shutter 60 and grid 80 with wires parallel to the movement of the drum (to break up the image) on to the charged surface. The latent image is then developed by cascading developer 27 from bucket conveyor 26. The developed image is then transferred to web 32 by electrostatic transfer unit 38. and fixed by heater 41. The drum is cleaned by brushes 42 and lamp 44. The grid 80 has between 50 and 300 lines per inch and may be placed in a separate shaft from the image shaft so that the charged surface is exposed to the grid either before or simultaneous to the exposure to the film so that large solid areas of charge are broken up and a better developed image is obtained.

Title: Extractor roll drive of continuous casting apparatus
IPC: B22D11/128
Filed: 1974-07-25
Abstract: 1443605 Driving pinch rollers/hauling between rollers GENERAL MOTORS CORP 25 July 1974 [20 Aug 1973] 32820/74 Headings B8A and B8B [Also in Division B3] A continuously cast bar, e.g. of ferrous metal, is withdrawn from a fixed mould (12) by a roll 16, Fig. 4, in a succession of forward steps, separated by comparable periods of dwell, occurring 120 times per minute, there being a slight reverse movement, e.g. 0À025 inch compared with a ¥ inch withdrawal stroke, during the dwell period. The roll 16 is driven with inevitable and variable lost motion effects, by a shaft 26, Fig. 3, through gears, the shaft rotating one-third of a turn, for each rotation of a uniformly-driven shaft 20, by the action of cams 22, 24 and followers 30a, 30b, 30c and 34a, 34b, 34c providing an intermittent drive, with a small reversed rotation during the dwell period. The roll 16 carries a brake disc 40, Figs. 4, 5, and, pendulously suspended by bearing members 42, 44e, a brake calliper unit 44 constantly gripping the disc to move with the disc and the roll as far as an ear 44g (depending from the unit 44) can move between an adjustable stop 48b and a fixed stop 52d. When the roll 16 and a reduced end 36d of a stub shaft 36, Fig. 5, extending from it, rotate in clockwise (withdrawal) direction, a spring-loaded pin 54 is pushed, by the ear 44g, back into the fixed stop unit 52 until the ear engages the stop 52d. This stops rotation of the brake unit 44 but the roll can continue to rotate against brake resistance until the roll and cast bar 14 are brought to a standstill. The spring-loading of pin 54 immediately exerts a reverse torque on the roll 16 by way of the ear 44g, brake shoes 44m, Fig. 4, and brake disc 40, until the ear contacts the adjustable stop 48b. The cams 22, 24, meanwhile, drive the shaft 26 in a slight reversed motion to reverse the roll 16 slightly. In the dwell period, after a withdrawal stroke, a fresh ring (13) of metal solidifies between the end of the cast bar and a boron nitride orifice plate (12b) located between the chilled mould (12) and a melt-holding vessel (10). The slight reverse movement of the bar 14 counteracts the effect of thermal contraction and facilitates welding of the new ring of metal to the end of the forming bar.

[Also in Group XIX] A measuring device which performs and classifies linear measurements in which light from the source 3, Fig. 1, is divided into two beams by slits in the shield 4, one beam is reflected by the mirrors 10 and 11 and forms an image of the slit on the measuring scale 8. The other beam is reflected by the prisms 12 and 13 and the mirror 10 and forms an image on the light sensitive member 7 which comprises a plurality of light sensitive units. The mirror 10 is attached to the pivoted arm 9 which is rotated by the sensing device 14 to a position which is a function of the dimension of the object 14a being tested. The light sensitive member is used to perform measurements in several ranges by varying its position, on the light beam axis with respect to the mirror 10. The size of the slit image on the photo-sensitive member is maintained constant in each position of the member by displacing the prism 13 in the opposite direction to the member, Figs. 2, 3 and 4 (not shown), whereby the total length of the beam path is maintained constant. Fig. 8 indicates the electrical arrangement, the light sensitive units forming the member 7 are indicated at 7a-7m, each cell is associated with a range or class of dimension values which depends on the position of the member with respect to the mirror 10. With the switch 75 off light incident on e.g. cell 7d causes relay 74d to operate whereby counter 77d is connected to the supply 76 and a count is recorded. False operation due to light overlapping adjacent cells is prevented by relay 74d opening theoperating circuits of the relays associated with cells 7c and 7e. Cumulative counting is performed by throwing switch 75 when in addition to' operating the counter associated with the cell being energized, a count is registered in all preceding circuits. To prevent false operation two arrangements (not shown) are described in which power is disconnected from the points 71 and 76 until the mirror has taken up the position determined by the size of the object being tested. In each case the operation is controlled by a switch which is operated when the object is inserted.

Abstract: 326,483. Morris Motors, Ltd., Seddon, W., and Cordey, R. F. Nov. 13, 1928. Compensating for wear; blocks and shoes acting on drums.-An automatically adjustable stop for limiting the motion of a movable part in one direction applicable more particularly for adjusting brakes and clutches for wear comprises in one construction, as applied to a brake, a series of balls h carried by a spring-ring i which holds them in contact with a fixed cylindrical part g while they engage also the tapered part of a thrust piece e by which the pressure of the rotary cam c is transmitted to the brake shoes a. The return movement of the shoes is thus limited by the wedging action of the balls. If due to wear, the movement of the shoes exceeds a predetermined amount, the part j of the piece c moves the ring i and the balls to a new position whereby the normal position of the shoes is kept constant. Wedges or. rollers may take the place of the balls. In order that the operating arm l of the cam mav have a constant stroke and initial position, it is coupled to the cam spindle by a one-way clutch comprising balls p disposed in tapering recesses in a part o rigid with the cam spindle and on which the boss of the lever l is mounted. A torsion spring q urges the cam to follow up the thrust pieces e. A construction is also shown in which thrust pieces and stop devices such as shown in Fig. 1 are disposed between brake shoes and a pair of operating pistons working in a common hydraulic cylinder.
