Patent DE-2558475-A1 (DE)
Title: Oligomerisation of alpha olefins - using catalyst system contg. aluminium alkyl halide, used in prodn. of synthetic lubricating oils
Inventor: LOVELESS FREDERICK CHARLES
IPC: B01J31/02
Filed: 1975-12-24
Abstract: A straight chain >=3C alpha-olefin is oligomerised by mixing with a soluble catalyst system in an inert atmos. at =200 degrees C according to the procedure of the parent patent, giving an oligomer of 20-60C. The catalyst system used in this addn. contains an Al-alkylhalide (I) having a 1-4C lower alkyl gp. and an organohalide having at least one satd. C atom to which only one atom of Cl, Br or I is bonded. (I) is present in the system at about 0.1 wt. % and a total halide: Al ratio of at least 2.5:1 is achieved. Used for prepn. of synthetic lubricating oils. The main patent proposes the use of a catalyst system comprising (I) and any organohalide. Use of the type of organohalide specified above gives oligomers having a viscosity index >100, a low pouring point and good stability to oxidn. The oils obtd. have a viscosity which changes very little with temp. In an example 2 liqs. comprising respectively 76.5 g 1-octene contg. 4 ml. 25% EtAl sesquichloride and 69.2g 1-octene with 10g brominated 1-octene (alkyl bromide) were mixed at 120 degrees C during 30 min. and gave an 83% yield of oligomer with mol. wt. corresp. to about 24C.

Title: Stay arrangement for door closing mechanism - has external regulator for adjusting stay roller relative to cam notch
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: E05F3/22
Filed: 1976-01-20
Abstract: The stay for a door closing mechanism has a closing spring resting against a plate cam by means of a roller. The plate cam has notches for holding the roller in the fixing position of the closing shaft for preventing closing by blocking the closing spring. This stay arrangement can be externally connected and disconnected optionally. The force of the closing spring is used for holding the closing mechanism shaft. The plate cam has an externally accessible regulator pin (13). The roller (6) is fitted into an opening in one position of the regulator pin. In another position the entering of the roller (6) into a notch is prevented because the regulator pin projects into the hole of the cam plate (7). The regulator pin (13) can slide between the notch (9) and the rotating axis of the closing shaft (3) and actuated by a plunger.

Title: Concrete shuttering with high easily calculated stress resistance - employs hinged couplings connected to cross members with screw fittings
IPC: E04G11/12
Filed: 1976-02-07
Abstract: Concrete shuttering can absorb a high degree of stress exerted in the longitudinal plane of the couplings. It is also possible to calculate easily and exactly the amount of stress which can be absorbed, eliminating the need for allowing large safety margins. The couplings (10) can be progressively attached be progressively attached to the crosspieces (7, 8) of adjacent shuttering elements using screw mechanisms which cooperate with the crosspieces because of an association of forms in the longitudinal direction of the crosspieces. The coupling itself is split into two coupling bars (12) hinged together at a pivot (11) with a screw mechanism attached to one of the bars. The screw mechanism is inserted into the holes in the crosspiece and the coupling and tightened to prevent movement.

Title: Temporary external glazing heat loss reduction - with detachable insulating layer applied to parts of glazed surface except small portion required for interior lighting
Inventor: DEUTSCHMANN DIETRICH DIPL ING
IPC: E06B9/04
Filed: 1976-02-28
Abstract: The process for increasing the resistance to heat passage on external glazed areas of buildings, is esp. applicable to modern buildings with large expanse of glass in the facade, normally leading to excessive heat loss and increased fuel consumption. For this purpose a layer of insulating material (2) is detachably applied to the glazed surface (1), with the exception of the area needed for daylighting the interior. Fixture can be effected by plug shaped-section units (3) and suction holders (4). External appearances may be improved by stretching a decorative material or foil (5) over the insulated surface, to blend with the character of the building. No structural alterations are involved, and the insulation is easily applied and removed.

Title: Post alignment and fixing device - has clamp and stop plates which screw together for displacement during alignment in hollow space base
Inventor: HAEGEBY FRITZ
IPC: E04H12/22
Filed: 1977-01-25

Title: Centring mechanism for trunk in veneer paring machine - has reduction gear in deflecting positions for chains linking hoists and scanners
Inventor: KETTELER OTTO ING GRAD
IPC: B27L5/02
Filed: 1977-02-17
Abstract: The device is for centering a round timber trunk in a veneer paring machine, with two prism-type hoist units at an interval apart, each supporting the trunk at two points, and each fitted with a scanner for determining the relevant centre point in the trunk cross-section. The scanners are linked to the hoists for counter movement, which is stopped on contact with the trunk at a third point. The hoist units (7) and scanners (9) are connected by chains (11) carried over deflecting positions (12). In each of these positions there is a reduction, in the form of chain wheels (17, 18), enabling the hoists to carry out thrust movement at a speed accelerated by the resultant factor. The scanners reach the trunk and break off the centering process only when the trunk centre point and centering centre point coincide.

Title: Pneumatic conveyor with explosion pressure wave restriction - has vertical section shot off at alternate ends by valve protected from contact with material
Inventor: KANICS ANDRAS DIPL ING
IPC: F16L55/10
Filed: 1977-04-27
Abstract: The system halts propagation of the pressure wave from an explosion in a pneumatic conveyor system handling free-flowing bulk material, dust or fluidised commodities in a closed pipe. The material is passed through a vertical section of the system acting as a pressure trap, and whose ends are alternately shut off by closing devices. The seat of the latter is protected from contact with the material. Thus the latter is alternately collected in the buffer chamber formed by the vertical section and then released from it. The devices can be arranged to move against the flow direction to shut the flow off.

Title: Input signal evaluation circuit - has two peaks in two parts of signal measured and compared for meeting specified relation (BE 14.10.77)
Inventor: HEDDEGEM LUCIAAN HECTOOR ELIAS
IPC: B07C3/14
Filed: 1977-05-04
Abstract: The evaluation circuit uses detectors and comparators. A first peak detector detects and registers a first peak value of a first part of the input signal. A second detector detects and registers a second peak value of the input signal second part. Comparators are connected to both detectors and continuously compare the first peak with the second peak. They check whether they meet a specified relation. The input signal is readjusted in accordance with comparison results. A third peak value detector is responsive to the trough shaped stage of the input signal to enable the other signals to be coded.
