Abstract: A method of assembling a gas spring from a closed end cylinder sub-assembly 32 and a piston sub- assembly including a piston, 36 piston shaft 40, shaft bushing 60 and shaft to cylinder annular seal means 58 comprises the simultaneous pressurizing of the cylinder sub-assembly with gas under pressure of at least several atmospheres and insertion of the piston assembly and seal means into the cylinder sub- assembly, which includes a predetermined quantity of lubricating oil, with immediate subsequent crimping of the cylinder open end to retain the piston sub-assembly and gas under pressure within said cylinder. The apparatus comprises two relatively moveable parts 74, 76 which are adapted to hold the piston and cylinder sub-assemblies respectively and, when moving towards one another to form a sealed cavity-by means of seals 112-which is pressurized with gas via point 124. Upon further movement towards one another the piston sub-assembly enters the cylinder and crimping occurs. The cavity is then vented and the cycle repeated. Constructional details of the gas spring are described and these include an end flange on the piston which yields to prevent jamming. <IMAGE>

Title: Two-stage catalytic process for removing contaminants from hydrocarbonaceous feedstocks
Inventor: GIBSON KIRK R
IPC: B01J35/10
Filed: 1982-09-23
Abstract: Hydrocarbonaceous feedstocks having high concentrations of metals and sulfur as contaminants are contacted with a hydrodemetalation catalyst in a first zone and then with a hydrodesulfurization catalyst in a second zone, the average temperature of the first zone being maintained at least 15 DEG C higher than the average temperature of the second zone. This increases the removal of the contaminants and provides a longer life for the catalyst system compared to both catalyst zones being kept at the same average temperature.
Patent GB-2135128-A (GB)
Title: An energy regulator
Inventor: ROYLE TERENCE GORDON
IPC: H01H37/30
Filed: 1983-02-10
Abstract: An energy regulator for regulating the power supplied to a heating element 12 consists of a slideable member 2 mounted in a supporting body 1 and kept constantly in contact with a cam surface 6 of a cam member 3. Movement of the member 2 provides a set angular disposition, dependent on the required temperature of the heating element 12, between a bimetallic temperature sensor 11 and a spring 14. As the temperature of the heating element 12 increases, the bimetallic temperature sensor 11 straightens, thus changing the angular disposition between it and the spring 14, until a point is reached when the spring 14 causes electrical contact 9 to snap upwards from electrical contact 8, so as to disconnect the power supply from the heating element 12. <IMAGE>

Patent GB-831608-A (GB)
Abstract: 831,608. Moulding concrete blocks. LANGDON, H. W., and WHATLEY, G. July 11, 1957 [April 13, 1956], No. 11353/56. Class 87(2). [Also in Group XXX] In a concrete block-making machine in which the blocks are formed on carrier plates, the plates are conveyed through the machine and, after removal of the blocks, back to the machine by a system of track sections extending in spaced relationship with one another between the entry and discharge ends of the machine with a further track section connecting the firstmentioned sections at the entry end, powerdriven impelling means for the plates being associated with each track section. The tracks comprise three straight sections 12, 13, 14 in the machine shown in Fig. 1, each having associated with it a carriage 26 (shown only for section 12) reciprocable longitudinally and carrying retractable pawls 32 to effect longitudinal movement of the carrier plates 11 in one direction. Each carriage is reciprocated by the oscillations of a lever, there being three such levers 18, 19, 21, one coupled to each carriage, and all oscillated by rotation of a common crank 15. The levers are pivoted at one end and supported at the other by curved tracks 23, 24, 25.

Title: Improvements in stapling machines
Inventor: KEMP JACK VOYNA LESLIE
IPC: B25C5/16
Filed: 1983-07-01
Abstract: A power-operated stapling machine comprises a plunger 16 which is moved downwards by the core 19 of the solenoid 20 to push an end staple 11a in a row of staples 11 through a stack of paper sheets and against an anvil 2 which bend the staples to hold the sheets together. The downward movement of the plunger 16 causes a link 29 to rock a lever 27 counter clockwise. This causes a wheel 26 to rotate the wheels 22, 23 clockwise whereby the wheels 22, 23 frictionally feed a row of staples 11 forwards until it catches up the rear end of the staples already in the machine. The machine operation is not interrupted meanwhile. Return movement of the plunger 16 promotes only an idle movement on lever 27. The lever 27 is connected to the wheel by a one-way clutch. A new row of staples is at once added to a guide bar 10 and is engaged by the second driving wheel 23. <IMAGE>

Title: Improved process for the production of protein fibres
Inventor: MAURICE TERENCE J
IPC: A23J3/00
Filed: 1983-12-02
Abstract: Smooth, elastic and even protein fibres are formed by extruding a mixture of protein micellar mass (PMM) and gellable starch into hot water. The starch may be present in an amount up to about 30 wt% of the PMM. A wide variety of properties can be achieved by varying the concentration of starch. An increase in fibre strength and elasticity is achieved at low concentrations of starch while softer fibres of increased moisture content result at higher concentrations of starch. The fibres are useful in a variety of food analog products.

Patent GB-2164201-A (GB)
Title: A fast electro optical shutter tube
Inventor: HARES JONATHAN DAVID
IPC: H01J31/50
Filed: 1984-05-19
Abstract: The electro optical shutter tube uses a ramp voltage to modulate the energy of electrons carrying an image parallel to a guiding magnetic field. The electron stream enters a velocity selective detector which selects a narrow range of electron velocities and hence gates a short frame from the electron stream. The duration of this frame may be much less than the risetime of electrical signals used to drive the tube. The modulating ramp voltage may be applied between the photocathode PC and the drift space entrance DEN, and a gating pulse is applied to a phosphor screen P so that it accelerates to energy sufficient to excite the screen, only those electrons having velocities in the range which brings them to the drift space exit during the pulse. <IMAGE>
