Title: Accelerating natural and/or synthetic rubber vulcanisation - using neutral to basic metal alkyl di:thiophosphate and higher mol. wt. di:thiophosphate
Inventor: VOORTMAN ALBERT
IPC: C08K5/5398
Filed: 1977-11-24
Abstract: Vulcanisation accelerators for natural and/or synthetic rubber contain, as active ingredient, a metal alkyl dithiophosphate mixt., (A), of natural to basic metal alkyl dithiophosphates and higher mol. wt. metal alkyl dithiophosphates. The mixt. is obtd. by reacting dialkyl dithiophosphoric acid having formula (RO)(R'O)PSSH (where R and R' are pref. 3-18, esp. 6-10, C alkyl) with a 5-50 mol % excess of a metal oxide or hydroxide, first at 20-30 degrees C and then at 60-80 degrees C. Use of mixt. (A), in place of an individual dithiophosphate, increases scorch time, e.g. from t5 24.7 - to 40.6 min. at 120 degrees C, thus prolonging safe storage and working time. The vulcanisates resist reversion and ageing.

IPC: C14B1/02
Filed: 1977-12-01
Abstract: Appts. comprises an initial wash and softening tank, a conveyor for removing the hides from the wash tank to the dung removal and drying stage. The conveyor consists of two horizontal belts between which the hides are gripped and transported. The last stage comprises a chain conveyor which grips the hide along the longitudinal axis in the direction of motion, a series of rotating drums with coms set horizontally beneath the moving hide and inclined at an angle to give the max. contact surface, between each drum a water spray bar directed at the hide and finally a roller with scrapers which removes the moisture from the surface of the cleaned hide. The chain conveyor consists of an upper chain with rubber pads which press against the smooth side of the hide and a lower chain with support plates on which the hairy side of the hide rests. Each drum comb is placed between an adjustable bar above the hide by means of which the distance of the comb tips from the hide can be precisely adjusted in accordance with the thickness of the hide. The ribs of the last roller are adjusted so that they are in contact with the hide and squeeze the water out of the hair. Water useage is minimised.

Title: Wind-sucking prevention system for horses - has sensor detecting initial muscular movements and applying electrical impulses to horse's neck
Inventor: SCHRIEVER ROBERT
IPC: A61N1/36
Filed: 1978-01-09
Abstract: The equipment reduces and/or prevents ticking and hiccuping or wind-sucking in horses, using the muscular movement on or before commencement to initiate impulses at the horse's neck. The horse is thus subjected to an electric shock just before performing the unwanted action, which causes a negative reinforcement effect. When the sensor indicates the beginning of a muscular contraction, one or several electrical impulses may be applied to the horse's neck.

Title: Overcurrent protection for rectifier fed loads - has comparator to which three signals, derived from load current and voltage, are applied
Inventor: VOELGER HORST DR ING
IPC: H02H3/087
Filed: 1978-03-13
Abstract: The loads are supplied through a rectifier with constant voltage regulation and superposed current control. A comparator (5) precedes a flip-flop (2) tripping the overcurrent protection. A first signal proportional to the load current is delivered by an amplifier (1) when the current exceeds an adjustable limit related to the load nominal current, and a second proportional to the load voltage are applied to it. The first signal ensures that the flip-flop is not operated at nominal load current and voltage. A third signal is derived from collapsing load voltage is applied to the comparator.

Title: Mining equipment lifting gear - includes traverse with lug carrying socket with shanks for chain connector for swing in all directions
Inventor: GOTTSCHALK GUENTER
IPC: E21F17/02
Filed: 1978-04-07
Abstract: There are hooks to grip a structural member on the carrier claw used in mines, with shanks holding a traverse acting in conjunction with a circular member for chain attachment. This traverse (3) has a lug (12) of a rotating hinge joint formed on it, with a socket (13) mounted to swivel round it. The socket has shanks for accommodation of the circular member (20). The lug, mounted crossways, can be housed in a traverse recess (10) with an opening from which the socket shanks protrude. This permits swivelling of the first part of the carrier chain, to prevent bend stresses on it when the chain is pulled obliquely, and ensures adequate rigidity in spite of limited traverse cross-section.

Title: Setting tool for torsion damper characteristic - has tool for compressing plastics damping ring bonded to outer peripheral inertia ring
Inventor: BIRKLE HANS GERHARD DR ING DR
IPC: F16F15/14
Filed: 1978-07-04
Abstract: A torsion damper consists of a dished hub (1) of highly ductile material, bonded through its flange (2) to a plastic ring (5), the latter being bonded to an inertia ring (6). The damping characteristic can be controlled by setting the radial compression applied to the plastic ring (5) to a given value. To do this, the assembly is supported in a base (8), while the flange (2) is forced radially outwards by a downwards force on the mandrel (10). This expands the forming tool (9), which consists of separate triangular segments (9a) inside the dished hub (1).

Title: Spraying mineral fibres onto an article - to insulate it and improve setting of binder which includes water soluble polymer
Inventor: NESER RUDOLF PETER
IPC: C04B28/26
Filed: 1978-09-25
Abstract: Metallic or non-metallic articles are spray coated with mineral fibres suspended in a binder consisting of a 1-10 (2-6) wt. % soln. of one or more alkali metal silicates mineralogically contg. >=15% kaolinite, together with one or more water soluble organic polymers which are resistant to alkalis and/or finely divided silica.

Title: Multipole plug connector with two sectioned housing - has shaft type compartments for contact brackets with plug holes and retainer
Inventor: AWAKOWICZ ERWIN
IPC: H01R13/436
Filed: 1978-12-06
Abstract: The multi-pole plug connector has an insulated housing formed from two sections joined together. It can be mass-produced by an automated process and it will also be possible to remove the contact elements from the housing without any special tools. The contact elements are in separate compartments in the same plane and project from plug holes. One section of the insulated housing (1) is made with shaft-type compartments (3). The cross-section of these compartments is of the same shape as the contact elements (4). The plug hole (10) is in the front wall of the compartment aligned with the contact. The other section of the housing (2) is at right angles to the plug axis and has a projection (12) which will reduce the size of the compartment to retain the contact. The two housing parts may have latching elements, working in pairs, thus affording firm, but releasable connection.

Patent DE-2854145-A1 (DE)
Title: Cartridge for thermal protection switch - has glass element to change state and trip switch by collapsing cartridge
Inventor: LEHMANN KARL HEINZ
IPC: H01H37/74
Filed: 1978-12-15
Abstract: The thermal protection switch uses an interchangeable (replaceable) glass cartridge. At a temp. below the operate temp. the cartridge is amorphous glass strong enough to hold the sprung switch units in closed circuit. Above the operate temp. the glass becomes crystalline and breaks so that the sprung switch levers open circuit the circuit breaker contacts. The cartridge (50) contains the glass, or vitreous, protection element (41) and the spring tensioning device (52, 59). The cartridge is constructed of a metallic bottom can (51) with an insulating top onto which a metal conducting plate (58) is fastened. The insulator/metal plate combination presses the glass element (41) hard onto the base of the bottom metal can (51). The base can (51) is connected to power (63) so that current flows through the can, glass element, and metal plate on top of the insulated cap, to the second power terminal (65). If the glass element collapses, due to change of state at the operating temp. the tensioning spring (59) extends to lose its tension and the cartridge collapses.
