Title: A device for sorting cylindrical bodies
IPC: B07C5/34
Filed: 1961-01-13
Abstract: 918,806. Sorting pipes. MUNCHNER MASCHINENBAU A.G. Jan. 13, 1961 [Jan. 13, 1960], No. 1535/61. Class 117. [Also in Group XXVIII] A device for sorting into two groups a number of cylindrical bodies, such as rods and pipes, comprises a first inclined support 12, 12<SP>1</SP> on to which the cylindrical bodies are delivered, a second inclined support 29, a shoulder 13 by which the cylindrical bodies moving along the first support are stopped, a gate 27 which, when opened, allows a cylindrical body to drop through the support, electrically actuated means 22, 23 for lifting the cylindrical bodies in succession from the first support 12<SP>1</SP> over the shoulder 13 on to the second support 29, electricallyactuated means 26 for opening the gate 27, and electrical control means which are designed to be set by a number of switches 31-34, one for each cylindrical body, and which are so arranged that they actuate in succession the lifting means 22, 23 and at each actuation also scan the position of the switch associated with the lifted cylindrical body in order to also open the gate 27 when one of the switches is operated. As shown, four pipes 1-4 are placed in a tank 10 and tested for leakage by introducing water into the tank and supplying compressed air to the interior of the pipes. If one of the pipes is shown to be leaky, say pipe 2, the corresponding switch 32 is actuated which causes a contact 42<SP>1</SP> to touch a contact 42<SP>11</SP>. A motor 17 for a controller drum is started up and switches itself off after one complete revolution. During this revolution a contact lever 19 is brought four times into contact with a contact 20, e.g. by means of four cams on the drum to actuate an electrically-operated valve 21 which conveys the pressure fluid to the piston-cylinder device 22. Simultaneously, with each actuation of the contact lever 19 one of the contact levers 51 to 54 is actuated and if the switch corresponding to the lever actuated has been pressed, an electrical circuit is made through a valve 25 which supplies pressure fluid to the device 26 so that lever 27 is pulled downwardly.

Title: Edible collagen casings for sausage meat and other foods and method of manufacture
IPC: B29C48/10
Filed: 1962-01-16
Abstract: 991,183. Collagen food casings; sausages. JOHNSON & JOHNSON. Jan. 16, 1962 [Jan. 16, 1961], No. 1554/62. Headings A2B and A2D. [Also in Divisions B5 and C3] An edible hyaloid or translucent food casing comprises cohered collagen fibrils and substantially no collagen fibres. The food casing may also comprise dispersed droplets of fat and, if desired, 10 to 20% by weight of cellulosic fibres such as wood fibres. The casing may be tubular and may be shirred. It may be filled with sausage meat to yield sausages. Alternatively, the casing may be in the form of a sheet or film, In producing tubular food casings according to the invention, comminuted hide, e.g. unlimed cow hide, is made to swell in an aqueous solution of a non-toxic acid, such as lactic acid, until the sheaths surrounding the collagen fibrils are ruptured and swollen collagen fibrils are liberated. The amount of collagen tissue dry solids in the non-toxic aqueous acid may range between 2.5 and 6% by weight. A pump 91, Fig. 1, forces the resulting slurry of collagen fibrils through a filter 93 and an extruder 90, from which the extruded casing is passed upwardly through a vertical column 95 containing a strong coagulating solution, e.g. a 42% solution of ammonium sulphate in water maintained at a temperature below 25C. and pH7 by adding ammonium hydroxide. The casing is pulled out of the column by a rotating roller 87 and perforated, e.g. at 2 inch intervals, by needles 30 on a rotating wheel 31, and is then passed through a similar strong coagulating solution in a tank 88. The strong ammonium sulphate solutions render the collagen fibrils unswollen. The casing is next passed through a more dilute, e.g. 4 to 10%, solution of ammonium sulphate in a tank 103 and then through a hardening solution, e.g. an aqueous solution containing 12%, by weight, of ammonium alum, 8% of ammonium sulphate and 2.8% of citric acid maintained at pH4.3, in a tank 21, Fig. 2. The hardened casing is passed through washing water in compartments 105, 106 and 107 of a tank 104 and through a plasticizing solution, e.g. a 6% solution of glycerine in water, in an adjoining tank 109. The plasticized casing passes, between rollers 116, into a drying chamber 115 and emerges therefrom, between rollers 117, to be wound on a take-up reel 124. In the drying chamber, the casing is dried in warm air, e.g. at 60 to 70C., supplied through a pipe 118 and the part of the perforated casing between the rollers 116 and 117 is kept inflated with air. The casing may be cured at 80C. and 20-30% relative humidity for 24 hours, re-humidified in air at room temperature and humidity, e.g. 75% relative humidity, and packed in hermetically sealed containers made of metal or other serviceable foil. If a small amount of formaldehyde is added to the hardening or plasticizing solutions, the heat-curing treatment may be omitted. Carboxymethyl cellulose and/or egg white may be added to the glycerine used for plasticizing the casing.

Title: Accelerators of vulcanisation and their preparation
IPC: C08K5/00
Filed: 1939-01-17
Abstract: 523,904. Vulcanization accelerators. DUNLOP RUBBER CO., Ltd., TWISS, D. F., and HALE, R. W. Jan. 17, 1939, No. 1556. [Class 70]. [Also in Group IV] A vulcanization accelerator for rubber is made by reacting an aldehyde which is substantially insoluble in water with a secondary dialkylamine in an aqueous medium. The term "dialkylamine" includes cycloalkyl amines and secondary amines in which the -two valencies are satisfied by a polymethine chain, e.g. piperidine. The aldehyde may Be introduced as a thin stream into an aqueous solution of the amine, or an aqueous suspension or emulsion of the aldehyde may be reacted with the amine. In an example, benzaldehyde mixed with potash soap and water is reacted with an aqueous solution of piperidine.

Title: Improvements in equi-signal radio beacons
IPC: G01S1/02
Filed: 1944-01-27
Abstract: 585,393. Directive radio systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and GREEN, E. Jan. 27, 1944, No. 1570. [Class 40 (v)] In an equi-signal radio beacon of the type in which modulated carrier is radiated from a central aerial and side aerial systems in predetermined phase relationship which is varied in dot-dash rhythm to produce the two radiation patterns, the depths of modulation of the carrier radiated by the central and side aerials are substantially different so that the combined radiation diagram is substantially different from the side band radiation diagram. The radiation diagram of the central aerial is a circle as indicated by rings A<1> to E<1>, Fig. 1 of radius depending upon the amplitude of excitation, while the side aerial system produces the two lobe diagram shown in dotted lines. The carrier excitations are adjusted so that the radius of the circular diagram is substantially equal to the mean of the maximum and minimum vectors of the two lobed carrier diagram to produce a resultant carrier diagram of the form shown in Fig. 2c, giving minimum undesired off-course signals and reasonable sharpness on course. The depths of modulation are adjusted to produce a resultant side band diagram, for example, such as that shown in Fig. 2a. A receiver fitted with a filter to remove harmonics of the modulation frequency produces a modulation frequency output, at any particular direction, which is limited to the amplitude of the carrier or side band diagram, whichever is the smaller. The effective radiation diagram registered by the receiver incorporating the filter is thus produced by superimposing the carrier and side band diagrams and drawing. the diagram which coincides with the inner of the two at all points. This resultant diagram may thus be made to have the optimum offcourse form while the discrimination on-course is determined by the modulation depth adjustments. An arrangement for series modulation of the H.F. amplifiers which are fed from a common H.F. source and feed the two aerial systems, is shown, the amplitude of modulating signal fed from a common source to each modulator being adjustable.

Title: Improvements in or relating to compound master cylinders
IPC: B60T11/224
Filed: 1941-02-07
Abstract: 547,040. Hydraulic master cylinders. HYDRAULIC BRAKE CO. Feb. 7, 1941, No. 1666. Convention date, Feb. 7, 1940. [Class 103 (i)] In hydraulic master cylinders, particularly for operating brakes, comprising a relatively large diameter piston effective for moving the brake shoes into contact with the drums and a smaller diameter piston by which the braking pressure is applied, the larger piston is gradually rendered ineffective by the provision of a restricted passage connecting the chambers forwardly and rearwardly of this piston. Relatively small and large pistons 44, 60 move in parts of the cylinder 20 of corresponding diameters. A restricted passage 64 connects the chambers 24, 22 through a hole 70 in the sealing cup 68. Chamber 48 is connected to the reservoir 10 by a passage 28. A passage 30 is provided for connecting the chamber 22 to the reservoir in release position. During initial movement of the piston in applying the brake, only a small quantity of liquid flows from chamber 24 to chamber 22, the chamber 22 being kept filled by liquid drawn from the reservoir through passage 28, chamber 48, passages 54 in the piston 44 and past the sealing cup 56. A large volume of liquid is thus displaced from chamber 24 but when, consequent upon engagement of the brake shoes with the drum, the pressure rises substantially, liquid is more rapidly displaced from chamber 24 to chamber 22 through the passage 64 so that the piston 60 is rendered ineffective. During release a vacuum tends to form in the chamber 24 and liquid flows to it from the reservoir through chamber 22, passages 66 through the piston 60 and past the sealing cup 68. A vertically disposed master cylinder is also shown with the reservoir at the side of the cylinder and with the restricted passage formed in the cylinder wall.

Title: Quick disconnect coupling
IPC: H01R13/633
Filed: 1963-01-15
Abstract: 959,432. Pipe couplings. ROBERTSHAW - FULTON CONTROLS CO. Jan. 15, 1963 [Jan. 16, 1962], No. 1825/63. Heading F2G. [Also in Division H2] The patent is concerned with a quickly disconnectable coupling for connecting oxygen supply and electrical apparatus to the personal equipment of an aircraft pilot or a hospital patient. According to the invention claimed the coupling comprises a delivery member 14 with a socket portion 26 with extended arms 28, 30 having opposed inner side walls 40 in which are apertures 174 with electrical contacts 176 projecting, a fluid flow passage 152 and a cavity 140 with an abutment 154 in the socket 26, a housing 36 having side walls 38 from which contact springs (Fig. 8, not shown) project through apertures to connect with the contacts 176 of the delivery member 14, a sleeve 64 slidable in a chamber 54 in the housing 36 from which its end portion 72 projects and is received in the cavity 140 to form a passage through both supply and delivery members; a valve 76 in the sleeve 64 kept shut by fluid pressure except when raised by engagement with the abutment 154 in the cavity 140, a latching bar 20 on the housing for engagement with a hook 24 on the socket 26, and a latching lever 106 biased to a locked position by the spring 60 of the sleeve 64 and movable to retract the sleeve from the cavity 140 permitting the valve 76 to close when the housing is rotated about the hook to disconnect supply. A hose 18 and wires 46 connect with supplies of pressure oxygen and electricity respectively and the nipple 34 with a face mask. The manner in which the housing 36 can be rotated downwards about the hook 24 and the sleeve end 72 inserted in the cavity 140 to form a through passage can be readily inferred from Fig. 6. The projection 154 does not contact the valve-end 78 to admit oxygen to the junction until after the electrical contacts have been made. To disconnect the operator lifts the latching lever 106 about its pivots 104 so that its other ends engage an actuating bar 94 which retracts the sleeve end 72 from the recess 156 of the socket. This thereby allows the valve 76 to close under oxygen pressure and shut off the flow before the housing is rotated upwards to break the electrical connections and to disengage it from the hook.

A slide projector comprises a slide track between light source and projection lens, feed and receiving chambers for slides on opposite sides of the axis, a reciprocable pusher plate in the track, resilient means in the feed chamber to urge the next slide into the track and means on the pusher plate to engage the next slide only and separate it from the remaining slides. In one form slidable magazines are spring- urged rearwardly to engage the rearmost slide in each against a plate in which a projection aperture is formed and which is also formed with guides for rebated portions 73 of a plate 70 having an extension 74 carrying an operating piece 76 outside the projector casing. The plate has a flange 80 at one end and has secured at 84 a spring plate 82 bent rearwardly at its edge 86. By pulling the plate into alignment with the slides in the feed magazine the flange 80 is engaged behind the edge of the rearmost slide which can thereby be pushed across into the exposure aperture, a wedge shaped portion 78 on the extension 74 urging the remaining slides out of contact with the moving slide. The end 86 of the spring plate 82 pushes any slide already at the projection aperture into the receiving magazine. As the plate is retracted to uncover the projection aperture the slide at the aperture is retained there by a spring frame.
