Title: Continuous mixer for rubber and plastic material - having two contra-rotating shafts with spiral blades
Inventor: RIUS ENRIQUE GUIX
IPC: B29C48/41
Filed: 1975-03-27
Abstract: Continuous mixer for mixts. of rubber, plastic and the like have two rotors turning in opposite directions inside a mixing chamber, provided with an inlet and an outlet with variable opening through which the mixt. leaves in the form of a continuous thread. The rotors and mixing chamber are divided into a feed zone and a mixing zone, in such a way that, in the zone with inlet the rotors rotate inside parallel chambers connected to one another at their sides, in the feed zone the rotors tun inside cylindrical parallel but independent chambers and in the mixing zone the rotors turn inside parallel chambers connected at their sides. The feed zone of each rotor is provided with a screw conveyor with double threads and double passages and the mixing zone of each rotor is provided with six spiral vanes, of which two, which are referred to as mixer-screw vanes are displaced in the circumferential direction at 180 degrees w.r.t one another and extend continuously over the entire length of the mixing zone and are divided into four sections.

Title: Arrgmt. for feed in and return control on grinding machines - includes a drive for the spindle head with program controlled motor
Inventor: GRAF ROLAND
IPC: B24B49/04
Filed: 1975-04-21
Abstract: The grinding machine includes a motor drive for the spindle head which is program controlled from a motor control system and an incremental pulse generator which generates series of electrical pulses corresponding to certain stretches of feed in or return stroke of the grinding wheel. The machine further consists of an evaluation arrangement which processes the information from the pulse generator and which, after computation of the paths, feeds the information in the form of a programme to the drive motor control arrangement. A capacitor (19) and a charging pulse generator (18) are mounted between the pulse generators (17) and the evaluation arrangement (2). The purpose of these is to convert the rows of pulses from the pulse generator to an analogue voltage change at the capacitor which corresponds with the path to be travelled by the grinding spindle.

Abstract: The electrolysis of an aq. alkali chloride soln. is carried out in an upright electrolytic cell, with 2 cation-exchange membranes between an anode and a cathode and consisting of an anode section, a cathode section and a middle section between the membranes. Aq. alkali chloride soln. is passed into the anode section continuously, whilst water or dil. alkali hydroxide is passed into the middle section continuously and the liquid in the middle section is passed into the cathode section and the resultant aq. alkali hydroxide soln. is removed from the cathode section. The liquid in the middle section is passed through this without uniform mixing, in a direction parallel to the surface of the membranes, forming an alkali hydroxide concn. gradient, the soln. from the part in which the cocn. is highest being discharged and passed to the cathode section. High current efficiency is attained and an aq. alkali hydroxide of high concn. (15%, i.e. ca 4.5 N or more) is obtd. The amt. of alkali chloride in the prod. is much lower than in the conc. and purified catholyte from the conventional diaphragm electrolysis process.

Heat insulating properties are at least equal to those of standard powdered compsns. Heat-expandable material helps to lower density and heat-conductivity of compsn.
Patent DE-2607205-A1 (DE)
Title: Aluminium metal high jump support with counterweight - has telescopic tubular stand with clamping screws and measuring scale
Inventor: KONIK BERNHARD
IPC: A63B5/02
Filed: 1976-02-23
Abstract: The high jump stand consists of two tubes which fit one in another. The aluminium outer tube is adjustable in height by means of a clamping screw and carries a measuring scale by which the height of the bar rest can be measured. The upper end of the outer tube is closed to keep out dirt and/or water. The iron inner tube stands on a foot piece which does not come into contact with the mat, and carries a counter weight in its cross piece. The minimum height of the stand is 1.55 metres which can be extended to 2.55 metres. This enables the height of the bar to be fixed accurately to any required height between 0.5 metres and 2.5 metres. Because the foot piece does not come into contact with the mat the bar cannot be vibrated off its rest after a successful jump.

Title: Fluid divider for surface distribution and collection - esp. etching fluid, maintaining constantly fresh supply without any problems
Inventor: BROWN SILAS A
IPC: B05B13/00
Filed: 1976-03-17
Abstract: A device has a detail with a number of fluid source channels for delivering the fluid to the working surface. The source channels are spaced some distance from each other, so as to distributed the fluid uniformly over the surface positioned some distance from the channels. The details with the fluid source channels also has a number of drainage openings spaced uniformly apart so as to collect and evacuate the fluid delivered by the source channels. A supporting arrangement such as a plate appropriately relatively to the detail with the fluid source channels, so that the object to be etched can be inserted between them and supported hydrostatically. This guarantees a high class accurately etched product by uniformly distributed and constantly refreshed fluid. There are no difficulties as with immersion baths and no possibilities of damage to the protective layers.

Title: Separation and transfer of vertical container stack - has pneumatically operated clamp and stop collar
Inventor: PESCHEL ARNO
IPC: B65G59/06
Filed: 1976-10-30
Abstract: A vertical stack of boxes (1) which contain ceramic objects is separated after firing and then transferred onto a belt conveyor (7). Whilst a pneumatic clamp cylinder assembly (10, 14, 18) retains the stack (1) with the help of two vertical rails (2), a second cylinder forces the lowest box loose so that it falls onto the belt conveyor. A second pair of pneumatic cylinders (6, 21) now moves a stop collar beneath the stack. The clamp cylinder is then retracted so that the entire stack is able to settle on the stop collar (6). At that point, the procedure is repeated for the removal of the next box.

Title: Phase identifier for chrominance signal in PAL decoder - uses phase detector connected to integrator to indicate phase
Inventor: MISKIN LESLIE THOMAS DR ING
IPC: H04N9/465
