Abstract: 1,155,730. Antitoxins. IMMUNE MILK CO. OF AMERICA, Inc. 24 Oct., 1966 [24 Oct., 1965], No. 47601/66. Heading A5B. Antitoxins are produced through the milk systems of female members of the equine, bovine, canine, porcine, hircine and camel species by a method including the steps of Iryper-immunizing said animal with a commercial toxoid, collecting the milk from the hyper-immunized animal, removing casein from the milk, concentrating the protein from the remaining milk serium of filtration, precipitation and centrifuging, emulsifying the concentrated residue with water, removing salt from the emulsion by dialysis, and collecting and freeze drying the remaining protein antitoxin. The collected milk may be diluted with sterile distilled water, the centrifuged sediment recovered in a sterile container, filtered, refrigerated and collected prior to emulsification with water. The animals may be given 5 cc. of commercial toxoid e.g. tetanus toxoid, at weekly intervals for a total of 8 weeks to produce hyper-immunization. Concentrated rennet may be thoroughly mixed with the diluted milk heated to about 100‹F. in the proportion of 5 parts by volume per 100,000 parts of dilute milk, said mixture is cooled to about 80‹F., permitted to coagulate for about one hour, agitated to break up the clots which have formed, and milk serum is withdrawn from the coagulated casein. Protein is precipitated from the milk serum by filtering the serum through multiple layers of cheese-cloth adjusting the pH to 6.8, adding ammonium sulphate, mixing thoroughly and holding: at about 40‹F.. for about 12 hours, siphoning off and discarding the clear supernatant liquid centrifuging at 20,000g the remaining precipitated protein solution, discarding the clear supernatant solution, placing the sediment on filter paper to absorb the remaining fluid, refrigerating for about 12 hours at -20‹F., recovering from the filter paper, emulsifying with water in the proportion of 10 gms of protein to 5 cc. of water, dialyzing against sterile distilled water for about 72 hours and freeze drying the remaining protein antitoxin. Antitoxins which may be produced by the above method include tetanus, diphtheria, staphylococcus, shigilla and botulinum, snake venom and toxins produced by micro-organisms such as bacteria e.g. Rickettsia, viruses, moulds and fungi.

Abstract: 996,421. Concrete mixers. A. F. GARLING- HOUSE, J. W. HALL, L. H. GARLING- HOUSE, and W. DEXTER, [trading as GARLINGHOUSE BROS.]. Dec. 16, 1963, No. 49619/63. Heading B1C. A concrete mixer has a flexible container 21 given a regular rhythmic deformation as by a wobble plate 25 to which it is attached ; the angle of the wobble plate is 5-30 degrees to the horizontal and preferably 27 degrees, when a rate of rotation of the wobble plate shaft of 400 r.p.m. will complete mixing in 2¢ seconds. As shown in Fig. 1, the mixer is mounted on a motor vehicle and may be elevated by a hydraulic ram 16 until it is in the position shown by broken lines, when it may be discharged through doors 45, 46. The container may have internal bosses, and/or a central column or cone describing a conical path (see Figs. 14 and 15, not shown). The container may alternatively be flexed by a roller following a circular path (see Figs. 7 and 8, not shown), or by plungers cam-operated in a circumferentially progressive sequence (see Fig. 9, not shown). In another embodiment, Fig. 10, the container 75 may take an elongated form and be flexed by a plurality of wobbleplates as at 76, 77, 78 ; it has a loading hatch 79 and discharge doors 87, 88 operated by a hydraulic ram 89.

Abstract: 1,199,060. Fastener driving tool. FASTENER CORP. 3 Nov., 1967 [19 Dec., 1966], No. 50050/67. Heading B4C. A pneumatically-actuated tool for driving fasteners, such as nails or staples, comprises a piston 26 movable in a cylinder 18 by means of compressed air fed from a reservoir 16 under the control of a valve means 20 and a control valve assembly 22 responsive only to joint actuation of trigger-and-safety control means 78, 80 in order to control the valve means 20. The control valve assembly 22 includes a valve piston 84 slidable in a cylinder 82 and provided with 0-rings 104, 106, 108, 110 defining chambers 112, 114, and 116. An exhaust valve 94 is slidable in the piston and cylinder 84, 82 and is formed with a head 94a for co-operation with a slot 92 in the piston. With the tool in the position shown in Fig. 3, air flows from the reservoir 16 through passages 118, 134, around the head 126 of a slidable valve member 122, a chamber 88 and passage 48 so as to maintain the valve means 20 closed .Upon pressing the nose of the tool against a workpiece so that the piston 84 is raised by the safety device 80 and then actuating the trigger 78 to open the valve 98, the pressurized air acting on the valve 20 is exhausted via a passage (90, Fig. 2) so that the valve 20 opens allowing air in the reservoir 16 to pass via a passage 46 to actuate the drive piston 26. At the end of the driving stroke, a valve 72 (more particularly described in Application No. 50050/67) in the drive piston allows air to pass through ports 62, a return reservoir 60, a passage 120 and a port 136 to thereby raise the valve member 122 so that the valve 20 is closed and the drive piston raised by the air in the reservoir 60. In a modification the piston 84 may be actuated by the trigger and the exhaust valve element 94 by the safety device.

Title: Measuring systems
Inventor: BARNES JOHN
IPC: G01B11/04
Filed: 1964-12-10
Abstract: 1,133,833. Electric digital calculators. SETPOINT Ltd. 3 Dec., 1965 [10 Dec., 1964], No. 50259/64. Heading G4A. In a measuring system for obtaining an approximate value of a parameter P known exactly only at certain instants, a digital function F according to the formula F m  = hP m +(1-h)F m-1  is generated, where h = 2<SP>-S</SP>, s being a positive integer, and P m  is the last known exact value of the parameter on the m'th step of the function, there being more than one step between successive ones of said instants, and the value of the digital function about 2<SP>S</SP> steps after the time at which the instantaneous value of the parameter is required being obtained. This function value approximately equals the required parameter value. As described, an 18-stage cumulative subtractor register R holds the current value of F. A control circuit driven by an oscillator enables two gates 1, 2 alternately. The first gate 1 passes the contents of the 12 high order register stages (F m-1 ) back to the register but shifted s = 6 places along to equal hF m-1 . This is subtracted from the present register content giving (1 - h)F m-1  in the register. The second gate 2 then passes the measured parameter value P m  in negative form to the 12 low order register stages, the other stages receiving ones. The quantity - hP m  thus obtained is subtracted from the current register contents giving (1-h)F m-1 +hP m , i.e. F m . A binary counter is incremented by one by the oscillator every step and when a read pulse is received indicating that the current value of the parameter P is required, the counter is reset. When the counter next overflows, the contents of the 12 high order stages of the register R are read out as the required value. The counter may overflow at a count of 2<SP>8</SP>, 2<SP>s</SP> + 1 or 2<SP>8</SP> - 1, depending on the form of the function P. The oscillator frequency may be adjusted to ensure that equal numbers of steps occur in the intervals between successive exact values of the parameter P, if these intervals are unequal. The length of a hot moving steel bloom may be obtained using fixed photo-cells spaced along the path or a rotating polygonal mirror to specify the position of the leading edge of the bloom at fixed intervals (of time) as the exact values of P, and producing the read pulse (see above) on detection at a fixed position of the trailing edge of the bloom.

A device for use in removing piston rings from a machine tool comprises a first jaw 2 carried on a rod 1 and a second jaw 3 mounted on one arm of a two-armed lever 4 which is pivoted at 5 on a support slide 6 which is adjustable along the, rod 1 to accommodate different sizes of piston rings. In operation, the device is located over a piston ring 9 in the machine tool, the jaw 3 being biased by a spring 8 so as to facilitate gripping of the ring between the jaws 2 and 3. Upon the release of the piston ring from the machine tool the normal resilience of the ring reacts against the pressure of the spring 8 so that the ring is lightly held between the jaws 2 and 3, Fig. 2 (not shown). The device is then swung into a release position, e.g. over a collecting pin, and a push-rod 10, Fig. 3 (not shown), operates on the lever 4 to move it about the pivot 5 against the pressure of the spring 8 and so release the piston ring on to the collecting pin.
