Title: Solid alcohol contg. copolymer resins soluble in aq. bases - useful as floor polish compsns.
Inventor: BRADY JOHN W
IPC: C08F246/00
Filed: 1976-07-05
Abstract: The resins are made by polymerising a mixt. comprising (A) 20-70 mole% of >=1 monomer, contg. no carboxyl gps. (B) 15-60 mole % of >=1 carboxyl gp. contg. monomer, (C) 3-20 mole % hydroxy cpds. comprising a mixt of alcohols with a b.pt >175 degrees C, and consisting of 10-90 wt.% of >=1 water insoluble alcohol; and (D) 0.1-1.0 mole % of a free radical polymerisation initiator. The alcohol contg. resin has an average mol. wt. of 600-4000 and an acid value of 60-250. The prods. are hard glassy solids which can be powdered and dissolved in an aq. base to form a homogeneous, clear, colourless soln. esp. useful as clear, non-yellowing floor polishes. In an example, a hard glassy prod. was made by polymerising a mixt. contg. 7.89 mole.% decyl alcohol, 8.55 mole % 2,2,4-trimethyl-1,3-pentanediol, 33.3 mole % methacrylic acid, 16.6 mole % methylmethacrylate, 33.3 mole % styrene and 0.33 mole % benzoyl peroxide. The powdered prod. was dissolved in aq. ammonia soln. to give a clear soln.

Title: Injection moulding hardness detected by sensor near sprue - which physically or electrically detects consistency change in material
Inventor: FINK ANTON ING
IPC: B29C45/76
Filed: 1976-07-17
Abstract: A device for optimising the use of an injection mould, which can be heated and in which the last portion of the moulding to harden is that adjacent to the screw, comprises a detector or sensor just inside the sprue opening, which provides a signal indicating the change in consistency of the moulding material. The sensor may be manually operated, or may comprise an automatic device for opening the mould when the moulding has set. With both these systems, the detector may comprise a mechanical plunger which is reciprocated periodically through the mouthpiece of the injection nozzle to detect the consistency of the hardened material. When hardening has taken place the movement of this plunger is limited. The detector pref. comprises electrically insulated electrodes, the change in electrical resistance between them being used to indicate the consistency of the solidified material.
Patent DE-2634321-A1 (DE)
Inventor: ZOOR REINHOLD
IPC: A63C9/00
Filed: 1976-07-30
Abstract: The adjustment device has an adjustment nut (4), through which pass two holes (17, 19) which substantially form an X-shaped cavity in the adjustment nut. One hole (17) is designed as a threaded hole and the other hole (19) as a smooth hole. An adjustment spindle (5) passing through the adjustment nut (4) can be pivoted relative to the adjustment nut about an axis which passes through the place (21) of intersection of the two axes (18, 20) of the holes (17, 19). The adjustment spindle (5) is connected, for example, to a fixed part of the ski binding, the adjustment nut being connected to a part of the ski binding which is adjustable in the longitudinal direction. If the adjustment spindle (5) is aligned with the smooth hole (19), displacement of the adjustment nut relative to the adjustment spindle, in other words rapid adjustment, is possible, whereas if the adjustment spindle (5) is aligned with the threaded hole (17) adjustment is possible only by twisting the adjustment spindle, so that only fine adjustment is possible. <IMAGE>

Title: Safety guard for shaft driven press - has latch operated electromagnetically by dynamo on press shaft against spring return
Inventor: BAUMANN WERNER DR ING
IPC: F16P3/08
Filed: 1976-09-08
Abstract: Safety guard for shaft-driven press has a dynamo connected to the press shaft. When the guard (2) is closed a spring loaded latch (9) on the guard snaps under a first locking plate (12) secured to an armature shaft of a torque relay (10). When on actuation of the press clutch, the press shaft begins to rotate, the dynamo eneergises the relay to turn the armature shaft and so introduce a second locking plate (13), over the latch. When the press shaft stops at the end of the press cycle the spring-actuated return of the armature shaft frees the latch.

Title: Sandwich plate forming system for heat exchangers - uses two stage inflation of plate between two stop plates
Inventor: KIND GUENTER
IPC: B21D53/04
Filed: 1977-04-02
Abstract: Double or multiple sandwich plates which are pressure welded together according to a certain pattern are inflated to form a heat exchanger section. The sandwich plate is placed between two plates (2, 3) which are placed a certain distance apart (a + x). The channels in the sandwich plate are now inflated at a first pressure till the bulging channels touch the two plates. The distance between the two stop plates is now reduced (a) so that the tips of the channels are partly flattened. During the second stage of inflation, an increased pressure is applied till the channels obtain a more rectangular section.

Title: Bulk material elevator conveyor - has two belts running close together with partitions forming closed chambers in between
Inventor: BARRERA-BERRO EDUARDO-LORENZO
IPC: B65G15/14
Filed: 1977-05-17

Title: Opto-electronic sensing system - has MIS capacitor with buried layer for each sensor, and also for read=out register
Inventor: KNAUER KARL DIPL ING
IPC: H01L27/148
Filed: 1977-09-12

A reading out register with a second MIS capacitor wit a buried layer collects charge carriers from the sensor. The two MIS capacitors without a gate electrode are coupled with each other owing to the two buried layers being directly adjacent with each other. The buried layers are uniformly doped layers, and the insulated layer thickness between the sensor electrode and the buried layer decreases towards the reading out register electrode.

Title: Reversing circuit monitoring for electric motor - involves utilising digital logic elements to give feedback signal
Inventor: BIELEFELD KARL HEINZ ING GRAD
IPC: H02P23/24
Filed: 1977-09-21
Abstract: The logic and switching block (K) is inserted between the power circuits of the motor and the low voltage circuits of the control system (MSB). The supervision of the forward switching state (RL) is given by a logical connection of motor current (J) and position of the reverse contactor relay (RR). For reverse rotation the opposite holds. The forward and reverse signals (AL, AR) are generated in the controller (MSB). The feedback signals indicate execution of the command or failure to do so. In the latter case they can also be used as diagnostic checks.

Title: Metallurgical furnace wall plate cooler - esp. for blast furnaces used in ferrous and non-ferrous metallurgy
Inventor: BINEVSKIJ VALENTIN N
IPC: C21B7/10
Filed: 1977-10-25
Abstract: A furnace wall cooler for a metallurgical furnace comprises a metal plate having at least two pipes formed in the plate with end portions of the pipes bent aside in the same direction. The end portions extend from the plate and are connected with end portions of pipes arranged outside the plate to form closed coolant circuits. Each of the pipes arranged outside of the plate are mounted in a chamber having in inlet and an outlet for coolant. Only a relatively small amt. of water flows through the closed circuit so that in the event of damage to a pipe only a small amt. of water penetrates to the furnace. Such an amt. does not affect the furnace operation. The other pipes in the plate continue to function irrespective of the damaged pipe.
