Title: Method of manufacturing glue in small pieces in the shape of granules or drops and glue manufactured according to said method
IPC: C09H9/04
Filed: 1928-01-30
Abstract: 284,704. Stockholms Benmjolsfabriks Aktiebolag. Feb. 4, 1927, [Convention date]. Glue. - In a process of forming glue into granules or drops, by allowing a glue solution to fall in separate drops on to a travelling surface, the surface is powdered with talc, chalk, boric acid, pulverized glue, starch, &c. or a mixture of such materials for the purpose of coating the drops which are subsequently separated from the surplus powder by sifting. When the drops are sufficiently stiff they are removed from the surface and dried. The stiffening may be accelerated by combining the surface with a cooling device wherein air, water &c. may be used as a cooling agent. The surface may comprise a rotating cylinder, conveyer belt or rotating disc.
Patent GB-807531-A (GB)
Title: Process for the production of castings
IPC: C21C7/06
Filed: 1956-01-31
Abstract: A process for the production of metal castings from melts containing oxide slag impurities capable of reduction by hydrogen comprises introducing a measured quantity of hydrogen as a gas or as a substance containing hydrogen, e.g., a hydride, and continuing the introduction so long as the temperature of the melt continues to rise.  Hydrogen gas may be introduced through a lance or a ladle having porous members, or by absorbing the gas on a metal, e.g. palladuim, and introducing the latter into the melt. A metallic hydride, e.g. calcium hydride or magnesium hydride, may be added in the form of granules coated with paraffin or a synthetic plastic or enclosed in a sheet iron container.  The addition of hydrogen may be stopped as soon as the temperature begins to fall or it may be continued to saturate the metal with hydrogen which comes out of solution on solidification and, by producing pressure in the still plastic metal ensures good contact with the mould and gives better surfaces to the casting. The hydrogen containing metal may be poured into moulds having an increased moisture content to produce a casting having a surface zone of a hardened structure.

Title: Improved direction indicating apparatus for vehicles
IPC: B60Q1/34
Filed: 1924-12-05
Abstract: 233,759. Rees, S., Roberts, C. O., Cross, J. H., and Lambert, H. F. Dec. 5, 1924. Road-traffic signals on vehicles. - A direction indicator for vehicles comprises sliding casings mounted on each side of the evhicle and adapted to be projected by springs or cables into their signalling positions from within a casing mounted across the vehicle. The sliding casings may be mounted at the front or rear of the vehicle and may be used in combination with pivoted panels mounted on each side of the vehicle at the rear or front according to the position of the sliding casings. As shown in Figs. 2 and 4, casings 2, 3 controlled by handles 18, 14 respectively are projected from within a casing 1 by springs 11, 10 when their corresponding handles are released The casings 2, 3 are withdrawn by cables 16, 12 which pass over pulleys on the handle and are attached to a fixed pin 15. This arrangement provides for the complete withdrawal of the casings 2, 3 from their signalling positions for relatively small movements of the handles. The handles are held in their normal positions by spring latches 30, Fig. 5. When the spring-controlled button 37 is pressed the corresponding handle is raleased and the signal casing is projected. When both casings 2, 3 are in their normal positions within the casing 1 the circuit of a clamp 31 is closed at the contacts 20, 21, 26, 27 to provide a coloured light for indicating that the vehicle is proceeding in a forward direction. Each easing 2, 3 has glass sides bearing hands 4 and contains a lamp which is automatically illuminated by contacts 28 when the casing is projected. The apparatus shown in Fig. 2 may be used in combination with spring-retracted pivoted casings mounted in housings on each side of the vehicle and connected by cables to the handles 14, 18. When a handle is released the corresponding casing 2 or 3 is projected by its spring and a pull is exerted on the handle 18 or 14 to project the pivoted casing mounted on the same side of the vehicle. Each pivoted casing contains a lamp which is automatically lighted when the casing is projected, by contacts on the pivoted casing or by spring switches mounted on the indicator shown in Fig. 2 and operated when the casing 2 or 3 is projected. In a modification, the casings 2, 3 may be projected by cables and retracted by springs. In this case the cables from the sliding and pivoted casings on each side of the vehicle are attached to a sliding bolt lever mounted on the steering pillar of the vehicle.

Title: Improvements in and relating to boiler feed regulators
Inventor: MORTON ALAN JAMES
IPC: F22D5/30
Filed: 1958-01-30
Abstract: 837,872. Feedwater regulators for steam boilers. PARSONS & MARINE ENGINEERING TURBINE RESEARCH & DEVELOPMENT ASSOCIATION. July 7, 1958 [Jan. 30, 1958], No. 3162/58. Class 123(2) In a water-tube steam boiler comprising a steam and water drum a connected to a superheater c, water is fed to the drum through a pipe d at a rate controlled by a regulator valve e the setting of which is determined by signals received pneumatically from a water level device f and a steam flow device g. The water level device compares a fixed head j of water with the head k in the boiler gauge glass i and transmits a proportional signal through a relay n to an operator o which tends to close the valve e upon a rise in level in the drum and vice-versa. The steam flow device g senses the pressure drop across an orifice in a superheater by-pass line m and transmits a proportional signal to the relay n, this signal overriding that from the device f when the rate of increase or decrease of steam flow changes suddenly. With this arrangement the sudden increase or decrease in drum level occurring with a sudden increase or decrease in said rate is reduced whilst, during steady load or steadily increasing or decreasing load, the feed water supply rate is controlled primarily according to steam flow to maintain the drum level substantially constant.

Title: Method and device for automatically and continuously determining  the filterability of a fuel
IPC: G01N11/02
Filed: 1974-01-23
Abstract: 1418431 Testing fuel oils COMPAGNIE FRANCAISE DE RAFFINAGE 23 Jan 1974 [24 Jan 1973] 03207/74 Heading G1N The temperature at which viscosity of a fuel oil becomes excessive for practical use in an I.C. engine is determined by measuring the time taken for a measured quantity of the fuel to be drawn up a pipette tube by a pre-set negative pressure. As shown Fig.1, a cylinder 1 is filled with the test oil 17 to the level of a spout 5 and a negative pressure is applied via tube 11 and valves 9, 8 to a pipette 2 which has a lower end inside cylinder 1 and an enlarged middle portion 16 containing two thermocouples 12, 13 connected in opposition, whereby their resultant output voltage is normally zero. When the fuel oil reaches the lower thermocouple junction an output pulse is produced which stops a clock initiated with the negative pressure. If this time interval is less than a predetermined critical value, the fuel 17 is replaced in the cylinder 1 at a lower temperature and the process repeated until the measured time interval exceeds the critical value. The temperature of the oil at which this occurs is recorded. The cyclic testing is automated.
