Filed: 1946-08-27
Abstract: 616,094. Paint sprayers. HARTMANN, K. A. Aug. 27, 1946, No. 25595. Convention date, Sept. 1, 1945. [Class 69 (iii)] Heated paint is supplied from a container to a spray pistol in excess of its consumption, the excess being led back to a second container under a suitable counter pressure. Compressed air from 38 through a valve 36 to the container 10 drives the paint under pressure through a valve and through a heated coil 18 to the pistol 26. This pressure drives the required paint out from the pistol and also returns the excess through a coil and a counter pressure leak valve 16 to the container 12. Alternatively, delivery may be made to the top of the container which is open to atmosphere through valve 36 and pipe 44. When the container 10 is nearly empty the valve 36 is reversed to drive the paint from the other container. The heater comprising the coils 18, 20 is immersed in a liquid and heated by electric heaters 32, 34.

Abstract: 645,556. Hook fastenings; locks. INGERSOLL, Ltd., YOUNG, L. W., and TAYLOR, J. W. Oct. 4, 1948, No. 25852. [Class 44] A lock comprises a casing 2, a bolt 3 pivotally mounted therein and projected or withdrawn by a slide 7 mounted for linear movement on a rail 8, locking means holding the slide at both ends of the linear travel and a rotatable key or knob operated member 17 movable first to free the slide from one locked terminal position and then to move the slide to its opposite locked terminal postion. A lever part 13 has a spring plunger 24 urging it to engage with the members 17 or with projections 23 on the casing one of which is adapted to engage in one of the recesses 15 in the arm to lock the slide in either terminal position. A cam part 25 formed on the member 17 first displaces the arm out of engagement with the projection 23 as the member 17 is turned. On' continued rotation, teeth 16 on the member 17 engage in the recess 15 and displace the slide along the rail. A nose 9 formed on the slide engages in a shaped opening 10 on the near side of the bolt so that the bolt is moved from the fully projected position (shown) to the fully retracted position as the slide moves from one end of the rail to the other. In the fully projected position a flat surface 11 on the rear of the bolt abuts the end of the slide 7 to prevent the bolt being forced to the unlocked position. A hooked end 6 engages over a wall of the staple plate 4. The member 17 is formed in two parts coaxially arranged and individually operable from either side of the door. Both parts may be operated by barrel locks or the inside one may be operated by a knob. Specifications 632,768 and 641,072 are referred to.
Patent GB-974910-A (GB)
Title: Polypeptide growth promoting agent for animals
IPC: A61K38/22
Filed: 1962-07-05
Abstract: The invention comprises an active polypeptide composition characterized by being electrophoretically homogeneous, having a molecular weight between 6600 and 8000, producing growth in stabilized adult female rats, producing a tibial epiphyseal response in hypophysectomized female rats, accelerating the utilization of glucose by muscle, accelerating the oxidation of C14 glucose by adipose tissue located in the intestinal section and also accelerating the rate of C14 amino acid incorporation into the protein of muscle and into the protein of epididymal adipose tissue. The polypeptide is prepared from purified preparations of animal or human growth hormones or from impure preparations containing these, e.g. animal pituitary glands or the acetone-insoluble portion of animal pituitary glands.  The growth hormone preparation is subjected to acid hydrolysis at a pH of 1.5 to 2.5 preferably in an aqueous medium containing ethanol, n-butanol, toluene and water in the proportions of 4 : 0.4 : 0.4 : 1 by volume.  The insoluble portion is recovered from the extraction solvent and dried, extracted with 0.1 M acetic acid, and the extract so formed is filtered through an ultrafilter.  The ultrafiltrate is passed through a cation-exchange resin on the hydrogen cycle, washed with water to recover unabsorbed material, and the aqueous solution treated with an ethanol-ether mixture to precipitate the active polypeptide.  The dried precipitate is dissolved in water, the pH adjusted to 8.5 with ammonia, the resultant solution filtered and the polypeptide precipitated by the addition of a mixture of ethanol and ether.

An arrangement for cancelling common mode interference signals in a balanced line L1, L2, comprises a high gain inverting amplifier A fed from the lines via identical resistors R1, so that balanced signals cancel and only common mode signals are amplified, the amplified output signals being fed back to the line via identical resistors R2 to cancel the common mode signals in the line. The amplifier, Fig. 3 (not shown), has a gain of about 500 and comprises a Darlington pair input circuit feeding a class B output stage with D.C. feedback overall (via resistors R3 and R4) to stabilize D.C. conditions, and A.C. feedback, via resistors R2 and R1, which tends to reduce cross-over distortion. The value of R1 is about 10 x R2.

Title: Improvements in and relating to Semiconductor Resistors
IPC: H01C1/14
Filed: 1967-06-06
Abstract: 1,173,444. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 June, 1967 [9 June, 1966], No. 26981/67. Heading H1K. A semi-conductor resistor comprises a body of semi-conductor material of substantially prismatic shape with one side face bevelled near one end face which is constituted by a surface of fracture of the material, the bevelled face and an oppositely located face being provided with electrodes in the form of metal coatings extending up to the edge of the surface of fracture. The resistor may be a phototransistor, a thermistor, or a varistor. The electrical characteristics of the devices are mainly determined by the semi-conductor material at the fractured surface, this being the shortest distance between the electrodes, which is relatively uncontaminated by electrode material. A plurality of devices may be simultaneously produced by forming a wafer (53) of semiconductor material having a groove (55) extending along one surface by compressing finely divided material in a mould and sintering, Fig. 3 (not shown), vapour depositing layers (57, 59) of gold on the major surfaces, Fig. 4 (not shown), breaking the wafer perpendicularly to the groove (55) to form a plurality of bars as shown in Fig. 5, and then breaking each bar along the line 63. A resistor for mounting directly on a printed circuit board has two opposed side surfaces bevelled, the electrodes extending from the bevelled surfaces to the opposite end of the body where they are soldered to the conductors on the board, Fig. 1 (not shown). The device may be a temperature-sensitive resistor made of sintered lanthanum-doped barium titanate with electrodes of vapour deposited nickelchromium. Alternatively the device may be a photo-sensitive resistor comprising a body of cadmium sulphide activated with copper and gallium. A plurality of photo-conductive resistors may be assembled in individual apertures in a thick plate (33) of light-absorbing insulating material to form a matrix, Fig. 2 (not shown). Each resistor may comprise a body of sintered copper- and gallium-activated cadmium sulphide with one bevelled surface and having vapour deposited gold electrodes. Connections to the resistors are provided by metal strips (39, 41) secured to the gold films by electrically conductive cement. The metal strips (39) connected to the flat sides of each resistor extend forward of the fractured ends of the bodies, and have their ends bent over and secured with electrically conductive cement to a conductive silver lacquer layer (47) provided on the upper surface of the mounting plate (33). The metal strips (41) connected to the bevelled sides of each resistor extend in the opposite direction and terminate in tags (45) which protrude into and are dip soldered to metal eyelets (50) in a thin insulating plate (49).
