Title: Multi-stage pressing device used for plates
Inventor: STAHLSCHMIDT DIPL-ING CARL
IPC: F04D29/16
Filed: 1968-11-07
Abstract: With the advantage of complete evenness of platen loading irrespective of any discrepancies in the thickness of the chip board elements being pressed, thus eliminating need for platen irons of varying thickness. Applicable to multiple platen presses with any number of platens. The lower press table supported on rams at the corners, independently controlled by level sensing instruments to ensure completely even raising of the table. The table is connected via a link rod in pivot connections at either side with lateral hinged fork arms on the upper press cross-head the lateral arms thus rising with the rising table. The individual platens are connected to this rising fork arm by means of linked tension rods, the thus rise together with the bottom table. Each tension rod contains a plate weight compensator in the form of a hydraulically loaded differential piston, and cylinder system, connected to a central hydraulic system, having a valve control system such that the load on a check piston is removed at the top of the stroke, thus applying full hydraulic pressure to the back of the piston which is dimensioned such that the load applied is more than the weight of the platen and its load.

Patent DE-1919713-A1 (DE)
Title: Hydraulically operated injection moulding - device
Inventor: HEHL KARL
IPC: B29C45/70
Filed: 1969-04-18

Title: Tri-n-octyl-aluminium prepn - from isooctene-contg octene
IPC: C07F5/06
Filed: 1971-02-20
Abstract: Tri-n-octylaluminium (I) (used in the prodn. of di-n-octyl-tin cpds. useful as stabilisers for Cl contg. polymers) is produced by treating octene contg. 0.1-5% isooctene of the formula CH2=CR1R2 (R1 and R2 being alkyl residues with a total of 6C) with HCl and, without sepg. off the isooctyl chloride formed, reacting with diisobutylaluminium hydrides (IIa) or triisobutyl-aluminium (IIb), the HCl-treated octene being added to (IIa, b) instead of vice-versa, so as to moderate the reaction. Despite the presence of isooctene in the starting material and the absence of a sepn. step in the process, the prod. is practically free from isooctyl cpds. which could give rise to toxic isooctyl-tin cpds.

Title: Safety mechanism for telescopic boom crane
Inventor: UCHINO HISANORI
IPC: B66C23/90
Filed: 1972-07-03
Abstract: The hydraulic jack includes cylinder inside which slides a tightly sealed piston linked to a stem extending out of the cylinder. It has a constraint detector to detect all load in the axial direction of the hydraulic jack, corresponding to the load on the stem.

Patent DE-2308987-A1 (DE)
Title: Candle filter with helical binding wire - of rectangular section to assist removal of filtering aids during back-flushing
Inventor: CHRISTIAN CHRISTOPHER WILLIAM
IPC: B01D29/15
Filed: 1973-02-23
Abstract: The Parent Patent describes a filter candle with inward flow and consisting of a perforated tube closed at one end and carrying an external fine-mesh sleeve. A helical binding wire holds the sleeve in place and an external filtering layer, esp. of kieselguhr, rests on the sleeve. The binding wire is of triangular section to facilitate complete removal of the kieselguhr. The improvement comprises using a binding wire of rectangular, esp. square, cross-section, with one face flat against the sleeve. This avoids the tapering effect which tends to lock the kieselguhr in place when the filter is back-flushed.
Patent DE-2331694-A1 (DE)
Title: Toilet cleaning brush - cleanser cartridge in handle, and button squeezes cleanser via channels onto bristles
Inventor: UGRINSKY ALEXANDER
IPC: A46B11/00
Filed: 1973-06-22
Abstract: The head and the handle of the brush are separable from each other. The handle is hollow and receives a container or cartridge containing a suitable cleansing agent with an outlet nozzle which fits into the entry bore on the brush head. Between outlet end of cartridge and head entry part a spiral spring is fitted. At the opposite end of the handle a knob, when pressed, supplies cleanser to the brush. This action can also be achieved by screwing the handle in one direction. Turning the handle in opposite direction or releasing the pressure on the knob stops the supply of cleanser due to the return action of the spring.
Patent DE-2351792-A1 (DE)
Title: Contact construction for distribution wiring socket - is made from sheet metal and without screw type cable terminations
Inventor: KRUEGER FRITZ
IPC: H01R13/11

Abstract: The contact construction has additional arms as well as those which form the spring contacts for holding the plug pins after insertion. The additional contacts form part of the arrangement for gripping the incoming wiring. For example one additional arm may have channels, and an opening to take the ends of the spring members attached to the other arm. The cables may then be inserted in the channels and pressed home until they are gripped under the springs. The spring contact arrangement may be attached to the corresponding arm by soldering. The connections are readily accessable, easy to manufacture, and permit an economical mounting assembly.

A damping device is provided to absorb the kinetic energy of the car as the wheel rolls off the cover. Part of the cover can be in the form of a slide movable against the direction of travel, and loaded by a spring acting in this latter direction. A controlled ram, acting on the slide, can be provided. Alternatively a hindrance can be provided on the track shortly after the cover.
Patent DE-2402193-A1 (DE)
Title: Refuse compactor with ram and refuse container - has opening in ram for feeding refuse into container
Inventor: BOOTON ALAN JOHN
IPC: B30B9/30
Filed: 1974-01-17
Abstract: The refuse compactor has a compacting ram which is moved by the drive into and out of the refuse container. The refuse is loaded into the container while the ram is still within the container. This ensures that the ram cannot trap a hand placed into the gap between the retracted ram and the container edge when loading the container. The box shaped ram has three actuating spindles driven by nuts from a motor with a belt pulley drive arrangement. The refuse is placed from above onto the ram whose underside aperture door opens when the ram is in the uppermost position. The ram door mechanism closes the droom automatically during its downward travel and opens the doors during its upwards travel.
Patent DE-2402774-A1 (DE)
Title: Noise absorber for high speed flow valves - is made from sintered ceramics as a cylindrical lining
IPC: F16L55/027
Filed: 1974-01-22
Abstract: This noise absorber used for pipelines or fitting carrying gaseous or liquid media at high flow rates, is arranged on the inside wall of the pipeline or in the fitting. This lining prevents direct contact between the high speed flow and the elastic structure of the pipeline and it prevents transmission of vibrations into the pipework or its fittings. In the diagram the housing of a throttling valve is connected to a steam supply line. The housing accommodates a valve closure unit which throttles the flow between the valve seat and the extension when the valve is partly open. A reflection noise absorber is fitted downstream of the valve seat. The housing is lined downstream of the reflection absorber with a sintered ceramic liner which has excellent noise absorbing properties so that any radial flow emerging from the reflection noise absorber cannot initiate any vibrations in the valve wall. The liner which can also be made from sintered metal has high stability and it is relatively simple and easy to fit and dismantle.
