Title: Improvements in and relating to the control of the air supply in the air mains of compressed air installations
IPC: F16K17/164
Filed: 1945-08-22
Abstract: 597,547. Locking catches for valves. HOLMAN BROS., Ltd., and ORAM, M. Aug. 22, 1945, No. 21488. [Class 135] A control valve for a compressed air installation adapted to close should the pressure of the air supply fall below a predetermined value, comprises a manually-operable butterfly valve member 5, mounted on ball or roller bearings and biassed to the closed position by a weighted operating handle 7 and retained in the open position by a piston 8 subjected to the air supply pressure. The piston acts through a lever 9, pivoted at one end to the valve casing and carrying.at its other end a roller 10 which coacts with the handle 7, the arrangement being such that the lever 9 is pushed outwardly to engage the handle and hold the valve open when the air pressure is above the predetermined value, but when the pressure falls below this value the weight of the handle 7 causes the lever 9 to be pushed aside, to allow the valve to close. The arrangement of the lever 9 and the handle 7 is such that the valve may be opened and closed manually, irrespective of the air pressure.

Title: An improved process of and apparatus for heating bulk material
IPC: C10B7/04
Filed: 1937-08-05
Abstract: 487,106. Carbonizing-apparatus; drying granular materials. KRUPP AKT.-GES., F. Aug. 5, 1937, No. 21600. Convention date, Aug. 24, 1936. [Classes 51 (ii) and 55 (i)] [Also in Group XIII] In carbonizing-apparatus in which the material moving in a thin layer is indirectly heated by a heating agent moving in the same direction, the container for the material comprises an oscillatable lower part on which the material rests and a fixed upper portion, the two parts being connected together in a gastight manner. The material is continuously supplied from a sluice 7 to the lower part 1 of the container, which rests on slightly inclined plate springs 9 which move to-and-fro, the material being discharged through a sluice 14. The upper part 2 of the container, which is held fixedly in a water seal 12 by rods 11, is provided with juxtaposed heating flues 3 to which the heating agent enters and leaves through openings 4 and 5 respectively. The liberated gases are withdrawn through a pipe 13 connected to the stationary part of the container. In a modification of the invention, the heating flues 3 are replaced by a single hollow channel in each half of the container and the liberated gases are withdrawn through a pair of side channels in the lower half of the container leading to a collecting main.

Abstract: 124,188. Murray, T. E., and Murray, J. B. March 9, 1918, [Convention date]. Projectiles.-In connexion with the electric welding of the edges of thin metal sheets forming halves of a shell, as for example by means of a very large current applied for a short time, means are provided for preventing a relative lateral displacement between the contacting edges so as to obtain a uniform joint. The halves D, E are seated in recesses in a movable electrode C, and a fixed one A mounted insulatedly on a base. Relative lateral movement between the electrodes during the welding operation is prevented by means of two rows of metal pins F secured in the electrode C, and co-operating with sockets in the electrode A lined with insulating linings G.

Title: Process for the extraction of oils from fish livers
IPC: C11B1/02
Filed: 1928-07-27
Abstract: 314,505. Manufacture de Machines Auxiliaires pour l'ElectricitÚ et l'Industrie. June 29, 1928, [Convention date]. Fatty oils, extracting.- Oil is extracted from fish livers by treating the ground livers to break open the cells containing the oil and extracting the latter by centrifugal treatment. The cells of the livers are broken open by (1) freezing before grinding (2) a sudden rise of temperature produced for example by adding hot water to the ground livers (3) by fermentation or (4) altering the osmotic pressure within the cells by adding pure or salt water. Two or more of these processes may be combined. The livers are passed through a mincer comprising grids having successively smaller orifices, water being added before or after admission to the second grid. The oil is separated in a centrifugal machine in which the mixture enters the central tube 5 and passes downwards into the rotating bowl 1 which is arranged to bring the surface of separation of the two liquids to the outer edge of the inclined plates 7. The water and remnants of liver are evacuated by the tubes 12 and the oil rises through the holes 15 to the outlet 16.

Title: Improvements in headlights
IPC: F21S8/12
Filed: 1921-08-23
Abstract: 192,430. Bone, E. P. Aug. 23, 1921. Vehicle lamps; lantern obturators.-A motor headlight is made with a lens having a rearward focal plane within the head-light, a light-concentrating reflector adapted to produce its area of greatest light concentration in the rearward focal plane, of said lens, and a screen or obturator at said focal plane encroaching on said area of intense concentration. In one form, an ellipsoidal reflector 2, Fig. 1, is fitted in the lampcasing 1 with the light source 15 at its rearward focus 3a, and has its front portion 2 modified to a more gradual curve. The lamp front 4 carries an aplanatic double-convex lens 5 having its rearward focal plane 9-10 within the lamp, which plane contains the front focus 3 of the reflector 2 and a screen or obturator 6. The screen 6 is of rectangular form and has on one side an upper projection. An inverted image of the screen is thrown forward with sharp definition into the field of illumination permitting a change, within a small angle, between the dark area so produced and the most concentrated portion of the beam, the lower dark area produced by the upper projection on the screen being on the side towards the centre of the road so as to prevent glare to approaching cars when the car is upwardly tilted on uneven roads. The reflector distributes the rays of light from the light source over the focal plane inside the lamp in gradually decreasing density radially from the area of greatest light concentration at the front focus, and thus effects even distribution of the light over the roadway. The screen 6, which may have its rearward surface 6<a>, Fig. 5, made reflecting, is vertically adjustable by means of an electromagnet 11, the screen support being pivotally mounted and having its front portion secured to the lamp-body by means of a spring 12 which draws it downwardly against a threaded pin 13; when the electromagnet is energized, the screen is raised against the tension of the spring. Reference has been directed by the Comptroller to Specifications 173,243, and 178,388..
