Patent GB-399090-A (GB)
Title: Improvements in and relating to the manufacture of building slabs
IPC: D21J1/00
Filed: 1933-02-17
Abstract: "Refiner stuff" from paper manufacture is mixed with water, binders, and if desired, fillers, and is felted and dried to produce building slabs.  A pressing operation during or after drying produces hard slabs.  In an example 2 per cent of resin and 2 per cent of water-glass in aqueous solution form the binder, which after felting is precipitated on the fibres by means of aluminium sulphate. "Refiner stuff" is the coarser fibrous material separated by centrifugal or jigger sorters from the fine wood pulp used for the manufacture of paper and card.

Inventor: GRIGO DAVID MOISEEVICH ROODKOV
IPC: C07C45/50
Filed: 1962-02-09
Abstract: Aldehydes are produced by the oxo synthesis at 170-200 DEG  C and 150-300 atm. in the presence of cobalt carbonyls formed in situ from an oil-soluble cobalt salt, the cobalt carbonyl being treated after the carbonylation step with oxygen or an oxygen-containing gas so as to form a non-volatile oil-soluble cobalt compound from which the aldehyde is separated by distillation, the regenerated oil-soluble cobalt compound being then recycled to the carbonylation reactor. The cobalt salt originally added to the carbonylation reactor may be, for example, the naphthenate, butyrate, or oleate.

Abstract: 907,526. Jet propulsion nozzles. GENERAL ELECTRIC CO. Feb. 13, 1961 [April 1, 1960], No. 5246/61. Class 110 (3). A jet propulsion nozzle comprising a convergent-divergent primary nozzle-section for receiving the engine working fluid and a secondary nozzle circumferentially spaced about the primary section to form a passage for the introduction of secondary fluid into the nozzle, in which the primary nozzle is axially movable relative to the secondary section to vary the throat area and discharge orifice of the nozzle, has throttle means in the passage connected to the primary nozzle so as to throttle the secondary air flow in accordance with the position of the primary nozzle. The jet propulsion nozzle comprises a primary convergent-divergent nozzle section 1 formed by a set of overlapping flaps 9 which slide axially along curved track elements 12 to vary the area of the throat 10 and primary discharge orifice 11. Track elements may be provided for alternate flaps only. The track elements 12 are mounted in a passage formed by the secondary nozzle section 2 surrounding the primary nozzle through which flows the secondary air which may be obtained from the compressor of the jet propulsion engine or may be ram air. The flaps 9 are actuated by motors 18 through linkwork 19, 20. To vary the secondary air flow, a throttle 22 is mounted on the rod 19. Movement of the throttle 22 relative to the frusto-conical passage 23 provides a throttling area variation which is linear with respect to movement of the primary nozzle 1. If desired, the passage 23 may be formed paraboloidally, hyperbolically or according to any desired function. Specification 896,484 is referred to.

Abstract: 567,613. Control systems for spoce-clischarge apparatus. BRITISH THOMSONHOUSTON CO., Ltd. April 2, 1943, No. 5286. Convention date, April 8, 1942. [Class 38 (iv)] [Also in Group XXXVII] Switching control.-An arrangement to prevent continued flashing of a faulty discharge lamp 10 having a starting switch S that operates to pass a heating current through the filaments 11 and then applies the full voltage between them, comprises an auxiliary switch X that opens the circuit of the starting switch after repeated attempts to start the lamp. In one construction, Fig. 2, the starting switch comprises bimetallic strips 21, 22 carrying contacts 23 normally separated, a high-resistance heater 25 that on closure of the switch P causes the strip 21 to bend and close the contacts 23 applying the heating current to the filaments, and a heater 26 operating when the contacts 23 are closed to bend the strip 22 away from the strip 21, so co-operating with the cooling of the strip 21 to open the contacts 23 and flash the lamp. Mounted near the heater 25 is a bimetallic strip 41 carrying a wire catch 44 forming one contact of the switch X that is normally closed by its engagement with the other contact 42 which is a spring strip biassed to snap out of engagement with the catch 44, but restrained thereby. The heater 25 operates continuously (except when the contacts 23 close), unless the lamp is running and after repeated attempts to start the lamp heats up the strip 41, which has a lagging 43, until it withdraws the catch 44 and allows the strip 42 to spring into the open position. The switch remains open until reclosed by manually operating a plunger 50. When applied to a glow-switch, Fig. 4 (not shown), a special heating coil is wound round the base of the strip 41. The construction, may be simplified by bending the free end of the strip 41 to form the catch 44 and by mounting the strip directly on the base. 30. A rectilinearly-moving rod may replace the spring strip 42. Specification 560,707 is referred to.

Title: Improvements in and relating to pulsators for milking machines

Abstract: 418,169. Milking-machine pulsators. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. Feb. 20, 1934, No. 5576. Convention date, March 18, 1933. [Class 84.] In a milking- machine pulsator which is controlled by a fluid streaming to and fro between two fluid-tight containers, one of the containers is placed in a pulsator chamber, or each of them is placed in a separate pulsator chamber and communicating with the pulsating pressure, the container or containers acting on elements controlling the distribution of high and low pressure, by the variations in volume of the container caused by variations in pressure within the enclosing chamber. Figs. 1, 2 and 3 show such an arrangement, in which a chamber 1, always open to the atmosphere, communicates, via valves 3, 4 and channels 6, 7, with two pulsator chambers 8, 9 and with nipples 10, 11 from which pipes extend to the teat cups. Chambers 12, 13 are in connection with the vacuum system of the plant through the nipple 14. The pulsator chambers 8, 9 enclose fluid-tight elastic containers 15, 16 communicating with each other by a pipe 17, throttled at 18, while a fluid-tight partition between the chambers 8, 9 supports the shaft 20<a> of a lever 19. When the pressure in the chamber 9 is higher than that in the chamber 8, air from the container 16 will stream into the container 15, the latter acting upon the lever 19 and moving the arm 20. When the pressure of the arm 20 is sufficient to overcome the pressure difference on the sides of the valves 3, 4, the valves are thrown over to their opposite seats, and the pressure distribution of the system is thereby changed. The container 16 will then expand, causing the valves 3, 4 to be returned. A modified form, dispensing with the lever 19, is shown in Fig. 4, while Fig. 5 illustrates a further modification provided with a rotating valve 29.

In an example, Fig. 2, a Ni core 3 containing a wafer of semi-conductor material is bonded to a alumina disc 2 and the disc to a Ni mounting stud 1 of the transistor by layers 5, 8 of Cu and layers 6, 7 of Ti. The assembly, in a graphite, Fig. 4, is compressed by a spring and outgased in a hydrogen atmosphere for 10 minutes at 1000‹ C. Next the assembly is heated inductively in a vacuum in the range 900-1000‹ C. for at least 2¢ minutes. Heating is reduced for at least a further 2¢ minutes to reduce the temperature to 700-770‹ C. for converting #-Ti to α-Ti. In another example, Fig. 3 (not shown), an improved joint is formed by recessing (11) one face of the mounting (1A) and using annular brazing washers locating over projections (10, 13) on the mounting (1A) and alumina disc (2A). The method may be used for bonding Ni to beryllia.
