Patent DE-2616813-A1 (DE)
Title: Bin or container loader for vehicle - has lever system with pivotal and vertically movable hook member
Inventor: MARKKU AIRAKSINEN
IPC: B60P1/64
Filed: 1976-04-15
Abstract: For loading bins and containers on a lorry there is a system of levers and a tilting, right angled member which has at its end (2) a device for hooking on to the load (4). This right angled arm is operated by a hydraulic ram (6). The load rests on a roller (8) mounted at the rear of the vehicle. There is a hawser between the roller and the ram so that the load can be hauled on. The whole apparatus is hydraulically operated and controlled and the right angled member swings through approximately 180 deg. This enables a bin on the ground to be gripped and then lifted up and on to the lorry.

Title: Determn of end of steel refining period - when mfg steel in oxygen converters, using accelerometer to show converter movement
Inventor: RAMELOT DANIEL
IPC: C21C5/30
Filed: 1976-05-04
Abstract: Process for controlling the refining of molten iron where industrially pure O2 is blown through at least one tuyere located below the surface of the bath, comprising a value characteristic of the converter movement during the oxygen blow and detecting the one or two moments when there is a sharp drop in this value. Starting from one or the other of these moments the amt. of O2 required is blown in to obtain the precise moment of the end of refining coresponding to the quality of the steel required, the amt. of O2 being determined with the aid of a relationship previously established, for the converter being used, between the amt. of O2 and either the amt. of P in the steel or the Fe content in the slag. The converter movements are pref. measured along the axis passing through the trunnions, using their amplitude, frequency or acceleration, e.g. by use of an accelerometer. Method eliminates the need for premature tilting of the converter e.g. for measuring the Fe in the slag, as the converter movements indicate the precise end of refining.

Title: Swimming pool surface solar heating and cleaning cover - with water film ducted to absorb heat and impurities
Inventor: BRUECHER FRITZ
IPC: E04H4/08
Filed: 1976-07-27
Abstract: The floating cover for a swimming-pool conducts daytime solar heat to the water, without building up an obstructive heat accumulation, and at the same time removing surface impurities, without any danger of these being later carried back to the water. The film of water to be heated is broken up into fine particles on the surface by the buoyant covering unit (4), or is carried through ducts (1) to the pool edges, and absorbs sun heat and any impurities that eventually arise. There can be a pool side U-shaped channel (5) with shank forming a movable floating flap (3), sucking in heated surface water and impurities, and returning water via a filter.

Title: Light sensitive resin compsn. contg. dichromate contains monomer - forming insoluble polymer for higher speed and adhesion
Inventor: OBA YOICHI
IPC: H01J29/20
Filed: 1976-07-28
Abstract: The compsn., based on a water-soluble polymer (I) which becomes insoluble when exposed to light in the presence of a Cr (VI) cpd. (II), contains 25-400, pref. 50-200 pts. wt. water-soluble monomer (III), forming a polymer which is insoluble or scarcely soluble in water, per 100 pts. (I) and 1-30 pts. (II). Used for the prodn. of printing plates. The speed and adhesion of the resin to the substrate are improved. Examples of materials are, for (I): gelatin, polyvinyl alcohol, polyvinylbutyral, poly(vinyl alcohol-CH2: CHCONH2), and polyacrylamide. As (II) (NH4)2Cr2O7, Na2Cr2O7, K2Cr2O7 or (NH4)2CrO4 may be used. An example of (III) is CH2:CR. COO(CH2)nOR' (in which R is H or Me; R' is H, Me, Et or Bu and n = 2 or R' is H and n = 3). The addn. of 20,40 or 60% polyethylene glycol 600 dimethacrylate to a compsn. based on PVA and 5% (NH4)2Cr2O7 reduced the min. exposure needed from 2.51 to 2.42, 1.65 or 0.95 klx-min respectively.

Title: High speed conveyor chain - is driven from linear motor via belt and balls to double speed
Inventor: POISEL OTTO KARL DIPL ING
IPC: B65G23/14
Filed: 1976-08-13
Abstract: The high speed conveyor chain is driven by a stationary liner motor and a moving belt. The belt is an endless one and coupled to a line of bearings with balls (7). Whose double rolling action gives the chain a speed double that of the bell. There is an adjustable three-point bearing for the chain, producing the necessary friction for the drive to be transmitted. The belt can be composed of sections whose pitch is that of the chain and which fit close together when travelling straight, but can vary their interval when passing round curves. The balls can have two opposite adjusting recesses and a groove running at right angles to them.

Title: Three phase twelve pulse rectifier - has two transformer secondary windings connected in phase opposed star
Inventor: KREFT VANJA DIPL ING
IPC: F02B3/06
Filed: 1976-09-29
Abstract: For reduced harmonic distortion from a twelve pulse rectifier system whilst keeping the transformer simple and using established thyristor control systems, two secondary windings (R1, S1, T1; R2, S2, T2) are both connected to a common star point but with their respective phases in opposition. The secondary terminals are joined to two separate rectifiers (M1, M2) commoned on the d.c. side. The preferred voltage ration between the secondary windings is specified for a current ratio of 3:1 so that the power transmission of the circuits is in the same ratio as the current, and it also allows the use of established thyristor controls. If one rectifier is faulty then operation of the other, with the appropriate output reduction, can continue.

Title: Freight container spreader for single hook crane - has ropes to frame corners with hydraulic cylinders for levelling
Inventor: WERTH HERMANN ING GRAD
IPC: B66C1/10
Filed: 1977-05-14

Inventor: NOWAK BERNT DIPL ING
IPC: B65G51/44
Filed: 1977-07-06
Abstract: The equipment works in a conjunction with an optical scanner unit to detect the destination of tube post slugs while travelling, there being code markings on the slug and markings at regular intervals to determine a detection rhythm for the optical scanning. The rhythm markings are rings (Rt, Ri) between front and rear guide rings (Rf1, Rf2) of the slug (1), and the code markings are superimposed on these rings so as to increase the diameter (Ri). The scanner unit has a first photoelectric cell for the rhythm markings and a second one set radially further outwards for the code markings. The first cell can be offset in the travel direction in reaction to the second for a distance equal to half the ring width plus the width of the interval between the rings.
