Title: Improvements relating to the production of ferment-containing dry products of animalglands or mucuses
IPC: A61K35/38
Filed: 1949-09-30
Abstract: Ferment-containing dry products of animal glands or mucuses are produced by roughly disintegrating the said raw material, soaking it in an aqueous salt solution the pH value of which is adjusted, by adding surplus acid or alkali, to a value which is reduced by the natural buffering capacity of the raw material to a value equal or approximately equal to the isoelectric point of the fermentative complexes contained therein, thereby causing salting out of these complexes within the cellular depots, and then draining and drying the material.  Preferably the salt solution is a solution of sodium chloride or bicarbonate, and the added acid or alkali is hydrochloric acid or sodium hydroxide.  In examples: (1) stomach mucos  of cattle are cut into strips, soaked in a saturated solution of sodium chloride acidified with 3.5 per cent hydrochloric acid, and then the strips are drained, finely disintegrated and dried with a blast of dry air, yielding a pepsin-containing product; (2) stomach mucos  of hogs are similarly treated, except that the quantity of hydrochloric acid is 2.8 per cent.

Title: Improvements relating to armoured electric cables
IPC: B23K11/087
Filed: 1938-10-17
Abstract: 515,416. Armouring electric cables. BARR, I. D. (Wessel, O. P.). Oct. 17, 1938, No. 25253/37. [Classes 83 (ii) and 83 (iv)] Angular bending; welding.-An apparatus for seam welding the upstanding longitudinal flanges of a ribbon such as of steel, iron, brass or aluminium in armouring on electric cable, comprises a pair of roller electrodes bearing on the flanges from opposite sides, the electrodes being supported on a base so that their axes are together free to move laterally. The ribbon 12, which may be from 0.8 mm. down to 0.6 mm. thick, is drawn by a drum 21 rotated through reduction gear from an electric motor first through rolls 11 which bend it to the section shown in Fig: 3a then through rolls 14, which shape it into flanged U-form, whereupon the cable 15 is introduced and the tube bent to the form shown in Fig. 3c by two pairs of rolls 16, 17. The rolls are laterally and also vertically adjustable. The flanges are then welded by a pair of bronze or other electrode rolls 18 and the armoured cable then passes through guiding and straightening rolls 19, 20 and is wound on a drum 26 driven by a belt from the drum 21. The forming rolls may reduce the thickness of the marginal portions of the ribbon. The roll electrodes are mounted on hollow vertical shafts 30 rotatable in vertically adjustable ball bearings 32 in bearings 31 carried by slides 34, which are freely movable laterally on guides 35 so that they can float and thus avoid bending of the seam laterally. The electrode pressure may be adjusted by a screw 36 and springs 37, the screw being threaded through a bridge plate 39 and the springs engaging bridge plate 40a. The plates 39, 40a are connected together by rods 41a slidable in openings 42a with machine base. The electrode pressure may alternatively be effected pneumatically or magnetically. The roll electrodes may be driven from the mill units and in order to counteract any tendency of the peripheral speed of the electrodes to exceed the linear speed of the flanges the electrodes are driven from the mill units by a transmission which can slip i.e. a friction transmission in which the friction is less than that between the electrodes and the flanges. This may oe effected by connecting the mill units by belts to pulleys 41, 42 on shafts 43 which are provided with slidable spiral gears 45 meshing with spiral wheels 46 carried by the shafts 30. The shafts 30 may alternatively be driven by flexible shafts from the pulleys 41, 42. Current is supplied to the electrodes by starting contacts 49 from a transformer and cooling water passes through a duct 51 and over a baffle plate 52 and shaft 30 to a drain 53.. The armoured cable is guided through the electrodes by a grooved idler 55 carried by a screw adjusted bridge 54.

Title: Improvements in or relating to coal face support systems
Inventor: JACOBI OSKAR
IPC: E21D23/14
Filed: 1964-06-18
Abstract: 1,039,835. Advancing mine roof supports. BERGWERKSVERBAND G.m.b.H. June 18, 1964, No. 25271/64. Heading F1P. The roof support units of a mine roof support system are arranged in groups I, II, III . . . each group comprising e.g. ten units 1-10 one of which is relieved of roof-supporting pressure and is continuously urged to advance towards the working face, thereby to maintain or reestablish contact with the working face until complete advancement thereof triggers a control signal which initiates the setting of the unit against the roof and also the relief of pressure in, and advancing of, a further unit of the group. When the further unit completes its advancing movement, it is set by the control signal then transmitted, whereupon the process is repeated in a closed circuit following on from unit to unit in a cyclic sequence. The signal transmitted by the last support in a group is passed to the first support of that group. Alternatively, the roof supports may advance in a random order in which the support not in contact with the working face is the support unit which is next advanced. The control signals may be transmitted by feeler switches, and a further switch on each support is maintained in continuous contact with the working face so as to detect when a support is unable to advance and to prevent each advancement although an initiation signal may have been received from another support. The advancing sequence may be controlled electrically, hydraulically or pneumatically.

Title: Improvements in or relating to apparatus for the storage of digital information
Inventor: KILBURN TOM
IPC: G01R33/04
Filed: 1954-08-31
Abstract: 814,941. Electric digital-data-storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 24, 1955 [Aug. 31, 1954], No. 25301/54. Class 106 (1). [Also in Group XXXIX] A matrix for storing binary number digits comprises magnetic storage elements with cores which may be saturated in parts by electric currents therein as described in Specification 814,942. In one arrangement, Fig. 1a, the cores each have two parts 10, 14 of low and high retentivity respectively, the parts 10 being saturable by currents therein without affecting the parts 14. Rows a, b, c of elements are connected in series so that parts 10 of all the elements of a row can be saturated together. Conductors 17 are linked with the elements of columns and are used for reading into or reading out from an element. To write into an element x, direct currents are applied to rows a and c to saturate the parts 10 but not the parts 14 and a pulse is applied to conductor 17 in column b<SP>1</SP> to saturate parts 10 and 14 of element x alone, the record being retained by the retentive part 14. To read out from x, an interrogating current in the form of a pulse, a series of pulses or an alternating current is applied to conductor 12 of row b to change the reluctance of the parts 10 and a read-out signal appears on conductor 17 of the column b<SP>1</SP> if part 14 of element x is saturated. Matrix construction.-The parts 14 may be strips of retentive material common to a row of elements or a sheet of retentive material common to a whole matrix. In one arrangement, Fig. 2, the non-retentive parts of a row of elements and the intervening conductors are formed as a strip 20 of " Mu-metal " (Registered Trade Mark). The strip 20 is laid over a strip of retentive material 15 with an intervening layer of insulating material to prevent conduction across the gaps 13. In another arrangement, Fig. 3, complete rings 10c and intervening conductors 12a are punched from retentive material. The rings 10c may be broken as at 13b to facilitate introduction of the conductors 17. In a third arrangement, Fig. 4, strips 10a of non- retentive material and conductors 24 are mounted on sheets 26, 25 of thin insulating material which are then assembled with a sheet of retentive magnetic material 22. An equivalent arrangement is shown in Fig. 5. A channelled sheet 30 and channelled strips 31 are of non- retentive magnetic material and together form tunnels or holes of rectangular section for the conductors 33. Between the sheet 30 and the strips 31 are strips 32 of retentive magnetic material on which the digits are recorded. Electric currents are passed along strips 31 to produce saturation when necessary. The sheet 30 may be dispensed with and the strips 32 may be replaced by a sheet of retentive material.

Patent GB-897201-A (GB)
Title: Production of polycarbonates
Filed: 1959-07-24
Abstract: Dry polycarbonates are recovered from a wet mass thereof containing a liquid nonsolvent for the polycarbonate (especially water), by first compressing the wet mass to remove a substantial portion of the liquid, then heating to remove substantially all of the remaining liquid, and finally extruding the molten polycarbonate.  The wet mass may be that obtained by impinging separate streams, preferably sprays, of a polycarbonate solution and a hot non-solvent whereby to volatilize the solvent and either (a) collecting the precipitated polycarbonate above a hot liquid body of the non-solvent (e.g. water at 80 DEG -100 DEG C.) or (b) stream-stripping the precipitated polycarbonate.  The solvent is preferably a partially halogenated aliphatic hydrocarbon (especially methylene chloride) but may also be dioxane, a ketone, tetrahydrofurane or xylene.  The non-solvent is preferably water but may also be a monohydric or dihydric alcohol, an aliphatic hydrocarbon or carbon tetrachloride.  Preferably, the wet mass, obtained as described above, is first allowed to stand on a screen or submitted to the action of a shaker screen to remove a predominant part of the non-solvent and is then fed into an elongated chamber where it is propelled forwardly by rotating screws which squeeze out most of the remaining non-solvent.  The polycarbonate is then gradually heated in a further section of the chamber to volatilize the remaining non-solvent and, if necessary, vacuum is applied.  Finally, the polycarbonate is extruded from the chamber through a die and the extruded product chopped and possibly allowed to drop into cold water.  The polycarbonate may be that of a dihydric phenol or aralkyl diol or a copolycarbonate of a dihydric phenol and an aliphalic or cycloaliphalic dihydric alcohol.  The solution of the polycarbonate may be that obtained by (a) phosgenation of a dihydric compound in the presence of aqueous alkali and the solvent or (b) reaction of a bis-chloroformate of an aliphatic diol with a dihydric phenol. An example describes the drying of a bis-phenol-A polycarbonate. Specification 772,627 is referred to.ALSO:Extruded dry polycarbonates are obtained from a wet mass thereof by feeding the wet mass to a twin-screw extruder in the first part of which most of the water is squeezed out and in the latter part of which the remaining water is evaporated by the application of heat and a vacuum.  Finally, the molten polycarbonate is extruded in spaghetti-like rods which may be chopped into granular particles about 1/8 inch in diameter. Specification 772,627 is referred to.

Title: Improvements in electric circuit controlling devices particularly for refrigerators
IPC: F25B49/02
Filed: 1939-09-08
Abstract: 532,576. Thermal switches; retractive switches; motor control systems. GENERAL MOTORS CORPORATION. Sept. 8, 1939, No. 25422. Convention date, Sept. 15, 1938. [Classes 38 (iii) and 38 (v)] A switch lever 51 controlling contacts 56, 57 for controlling the running and starting windings 72, 71 of a refrigerator motor is moved into the "on" position by rotation of a hand knob 111, is moved automatically to cut out the starting winding by the expansion of a wire 80 in a motor circuit and to cut out the running winding also by still further expansion if the motor is seriously overloaded and is also to cut-out both windings when the temperature of the refrigerator falls sufficiently low by the contraction of a bellows 150 which acts on the switch 51 through the wire 80. The hand knob may also be depressed by the closing of the refrigerator door to move a shaft carrying a cam 116 controlling a spring contact 102 co-operating with a fixed contact 117 to close a circuit to a lamp illuminating the refrigerator cabinet, Fig. 9. Rotation of the hand knob 111 rotates the above shaft which carries a cup 115 having sliding engagement with a bolt 134 which has threaded engagement with a lever 83 pivoted at 84. The lever 83 is thereby rotated till its left hand end engages a stop 160 and, acting through the wire 80, rotates the switch 51 to bring contacts 56, 57 simultaneously into engagement with their fixed contacts so starting the motor. Temperature regulation is effected by further rotation of knob 111 thereby compressing the bellows to a variable extent.
