Title: A process for the production of ferment preparations
IPC: A61K35/60
Filed: 1932-02-22
Abstract: Ferment preparations suitable for carrying out proteolytic and/or lipolytic processes are obtained from the pylorus attachments of fish other than plagiostomi.  The pylorus attachments are worked up by the processes usually employed in the case of organs of slaughtered animals or by other known methods. The attachments may be comminuted and used direct in aqueous suspension in the drenching of skins and hides, or they may be dried and extracted with organic solvents. Thus, the pylorus attachments are separated from the shell fish or herring, finely comminuted, defatted with acetone or ether and, after separating the solvent, dried.  Alternately, the mash of organs can be extracted with dilute alkali.  The dry preparations may be mixed with sawdust, inorganic salts or other carriers and diluents as well as activating additions or preserving agents.  After suitable fine grinding the product can also be worked up in known manner into pharmaceutical preparations.ALSO:Ferment preparations, which can be worked up after fine grinding into pharmaceutical preparations, are obtained from the pylorus attachments of fish other than plagiostomi.

Title: Submerged floatable hoses for transporting oil and other liquids on the sea
IPC: F16L11/133
Filed: 1964-02-10
Abstract: 1,048,961. Pipes; pipe joints. BRIDGESTONE TIRE KABUSHIKI KAISHA. Feb. 10, 1964 [Feb. 13, 1963 (2)], No. 5405/64. Headings F2G and F2P. A method of conveying oil or other liquid over an expanse of water using a hose pipe consisting of two substantially coaxial tubes 1 and 2 with an interspace 3 between them comprises, when the liquid is to be conveyed, filling the interspace with air so as to cause the hose to float, and, when the conveyance of the liquid is completed, either replacing the air with water or evacuating the air in said interspace to cause the hose to submerge. As shown, the interspace between the inner tube through which oil may be passed and the outer floater tube is sealed by an end flange 4, adapted to be connected, for example, to a similar flange of another length of pipe and having sleeves 5 and 6 secured to the outer and inner tubes respectively, an opening 3<SP>1</SP> being provided in the flange through which air or water can be fed in or extracted by a pump. In a modified arrangement, Fig. 3 (not shown), a separate pipe 7 is used to extract or feed fluid to the interspace. The hose is of rubber, reinforced with wires or fibres as necessary, the outer tube being sufficiently flexible when it is intended to merely evacuate the interspace to sink the hose so that the outer tube collapses about the inner tube on evacuation of the interspace. As illustrated in Fig. 4 (not shown), the hose, shown in both its floated and submerged positions, A and B, respectively, is connected between a ship 10 and a buoy 9, the latter being connected to a permanently submerged pipe 13 and being provided with a pump and the necessary control valves.

Title: Numerical positioning control
IPC: G05B19/25
Filed: 1969-01-31
Abstract: 1,255,975. Programmed positional control. GEORG FISCHER A.G. Jan.31, 1969 (Feb.2, 1968], No. 5442 /69. Heading G3N. A numerical positional control arrangement for one of two movable members of a machine tool whilst the other of said members moves independently, has a first input receiving programmed co-ordinates representing successive tool path sections, a second input signal from the tool representing positional changes of the other movable member, and an interpolator for obtaining from the programme a slope value for each successive path section and for generating in accordance with this slope value a feed signal which is dependent upon the positional change signal. A machine e.g. a lathe has a carriage moving linearly at constant speed which carries a cross slide 15 disposed at a fixed or variable angle # to the carriage movement, the tangent (f) of which should be the ratio of two whole numbers e.g. 5/3. The carriage displacement (z) causes a generator 18 to deliver pulses e.g. one pulse per 0À01 mm. through a distributer 21 to one of three frequency dividers 22-24 having ratios of 3, 5, 2 respectively. The slide 15 is driven by a pulse motor 17, or other servo drive in a coordinate direction (x). The data carrier, e.g. magnetic tape or punched cards, contains information regarding x, z, and f which is read into means 2, intermediate store 3, and on command to storage counters 4-6 respectively. The required tool displacement is divided into linear sections having co-ordinates z, x and slope x/z = f. If/is greater than x, f is programmed to be equal to x. The continuous z pulses from generator 18 after division by 5 in divider 23 are subtracted from counter 4. At each subtraction the slope number f is added to the total in a counter 7 and when the resultant reaches "1" this number is deducted from the total and the number in counter 5 is simultaneously reduced by one and the drive means 17 displaces the tool in the x direction by one increment of displacement, the actual movement being x/sin #. To compensate for displacement of the tool in the z direction, each x pulse activates divider 22 and on each third input z pulse an output pulse from divider 22 switches the pulses from generator 18 back to divider 23, or if the total in counter 7 is still at least 1, an output pulse from divider 22 triggers a further x movement. An incremental x movement in the negative direction connects the divider 24 which operates in the same manner as divider 22 in the positive direction. Due to the high reading speed of means 2, it is possible to produce curved contours by resolving curves into small linear sections. The angle of the cross slide 15 may be changed by a programmed pivoting of the guide tracks.

Combustion equipment, for example of a gas turbine engine, comprises an outer casing 12 and an inner flame tube 11 which is closed at one end 16, fuel admission means 19 being located adjacent the closed end of the flame tube and means for admission of primary air being disposed opposite the fuel admission means, the primary air and the fuel admission means being positioned at opposite sides of the flame tube. Additional air is admitted with the fuel, and the primary air is admitted through vanes which impart thereto a rotary motion about an axis substantially perpendicular to the axis of the combustion chamber. The closed end 16 of the flame tube is connected by an expanding portion 15 to the main portion 13 of the flame tube. The fuel injector 19 injects fuel through the aperture 18 through which some primary combustion air also passes being guided by a deflector 21. Opposite the injector 19 is disposed a vortex chamber 22, air entering at 27 passing between the swirl vanes 29 and issuing through the throat 26 into the flame tube as a vortex having a hollow core 30. The fuel and air entering through the aperture 18 enter the core 30 in the vortex flow and the fuel and primary air mix as shown by the arrows 38. Further primary air enters through the openings 31 and dilution air through the openings 32. In a second embodiment, the flame tube is built up of overlapping tubular sections of increasing diameter. The combustion chamber shown in Fig. 6 comprises an annular flame tube, the outer and inner walls of which are built up of overlapping tubular parts, which is disposed between outer and inner air casing walls 71, 72.

Filed: 1961-02-15
Abstract: 926,395. Microfilm cameras. PHOTO COPIE G.m.b.H. Feb. 15, 1961 [March 30, 1960], No. 5601/61. Drawings to Specification. Class 98 (1). In a microfilm flow camera having interchangeable lens for photographing documents of different widths, a switching device is provided by which different pairs of markers are brought into operation indicating the maximum document width for which the camera is set to film and a lens appropriate to that width is moved into or retained in the operating position and the speed of movement of the document or film appropriate to that width is selected. Typically the document speed is kept constant and for the different document widths one or more manual operations of an electrical contact lights the appropriate pair of marker lights, moves a lens turret disc or slide through the appropriate indexing distance, and engages an electromagnetic clutch for the film feed roller of a diameter appropriate to speed corresponding to the lens selected, each roller having its own clutch. Provision is made for the use of films of different width, this necessitating change of film magazines and of film rollers to the width chosen, such change being also adapted to bring into operation a different set of document width markers. Instead of manual operation of the contact controlling the markers, lens turret and film feed roller selection, the contact may be operated by means controlled by photo-electric scanning of the document to determine its width.

Title: Improvements in automatic adjusting devices for brakes
IPC: F16D55/228
Filed: 1953-02-28
Abstract: 738,034. Automatic adjusting devices for brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Jan. 19, 1954 [Feb. 28, 1953], No. 5672/53. Class 103 (1). In a brake device to automatically compensate for wear of the friction members, two pins 28 extend axially one each side of the piston and cylinder mechanism (12, 6) in the "spot-type" disc brake illustrated; each pin has one end associated with a friction pad 8 and is slidably fitted through a sleeve 17. One end of the sleeve is longitudinally slotted 20 and is provided with a part-conical end 19 and is threaded adjacent said end. A nut 26 having a partconical end of the sleeve is screwed onto the sleeve, so that rotation of the nut on the sleeve tightens the slotted part of the sleeve about the pin until a predetermined degree of interference has been obtained. As the friction pads 8 and backing plates 9 are moved towards the disc 1 they move the pins 28 secured thereto in the same direction and also the sleeves 17 secured to each pin. Each pin moves until the shoulder 18 thereon contacts the annular stop 16; the helical spring 23 compressing during the process. On release of the braking pressure the spring 23 retracts the assembly 17, 28, 26, 9 and 8 until the shoulder 18 on the sleeve 17 is again contacting the flange 22 of the distance piece 21. The friction pads will then be spaced away from the disc by the amount of clearance 25 between the shoulder 18 and the stop 16. As the friction pads wear the braking force will overcome the resistance between the pin and the sleeve and draw the pin through the sleeve to automatically compensate for wear of the pads. On the braking load being removed, the pads will again retract their predetermined distance 25, as explained above. The device may be applied to any suitable type of disc brake and with suitable modifications it will also be suitable for drum brakes. The Provisional Specification describes the invention applied to an alternative form of vehicle disc brake. Specification 688,382 is referred to.
