Patent DE-3843549-A1 (DE)
Title: Protective cover for the piston rod of a hydraulic telescopic vibration damper for motor vehicles
Inventor: BERNDT WILHELM
IPC: F16F9/38
Filed: 1988-12-23
Abstract: In conventional protective covers with protective sleeves or bellows of variable length, a considerable part of the damper tube surface is covered by the protective sleeve or the bellows, especially where the piston rod is intended to run completely into the damper tube. The said cover adversely affects the cooling of the vibration damper, which is disadvantageous especially in the case of high performance dampers subject to high thermal stresses. Using a bellows of variable length, the new protective cover is intended not to adversely affect the cooling of the damper despite a part of the damper tube surface being constantly covered. For this purpose a cylindrical carrier part arranged on the damper tube for fixing the bellows is designed so that an axially continuous peripheral radial gap is formed between the cylindrical carrier part and the vibration damper tube, by way of which intensive cooling of the said damper tube area occurs as the piston rod runs in and out. The protective cover is especially well suited for use in those hydraulic telescopic vibration dampers which are subject to high thermal stresses, but is not confined to such an application. <IMAGE>

Title: Process and apparatus for the temperature control of moulds for the processing of thermoplastic materials
IPC: B29C45/73
Filed: 1989-02-24
Abstract: To provide a process for the temperature control of injection moulds by means of cooling water, the mould having a plurality of cooling channels which are in each case connected by an inflow and outflow to a flow control device for the cooling water and all the inflows and outflows of the flow control devices opening out into a common inflow or outflow channel, into which the cooling water is fed via a preliminary temperature-control device and from which the returning cooling water is conducted to the preliminary temperature-control device, by which process independent heating and cooling of the moulds to the desired set temperatures is possible, it is proposed that the preliminary temperature-control device should control the flow temperature of the preliminary temperature-control circuit by means of a temperature-controller in such a way that during heating the controlled variable chosen should be the highest temperature set value of the flow controller set temperatures plus a spread and that the heating should be maintained until the thus-defined highest flow temperature is reached, that after reaching this highest value the temperature controller should switch over automatically and then, during cooling, the chosen controlled variable should be the lowest temperature set value of the flow controller set temperatures less a spread. <IMAGE>

IPC: B42C9/00
Filed: 1989-05-03
Abstract: A binder for binding loose leaves in book covers, which are provided on their cover back with a strip of melt adhesive, has a frame structure and two parallel support walls which form between them an insertion shaft for inserting the book covers filled with the leaves, which insertion shaft is bounded at the bottom during the binding operation by a heating plate.

Title: Erecting projectile fins by compression spring energy - applied to piston axially mobile in cylinder with apertured wall
Inventor: BAYER KARL DIPL ING
IPC: F42B10/20
Filed: 1989-05-31
Abstract: The fins (12) which erect from a projectile after firing do so by pivoting about pins (14) disposed near the cylinder (32) providing the motive power for erection. The cylinder holds a piston (34) axially movable from the first position, with the fins retracted, with the second position with fins erected, under the action of a power storage element (36), e.g. a compression spring, losing most of its stored power during the advance. An internal throttle (42) links the cylinder cavity (40) with the external atmos. The cylinder wall has a progressively obscured aperture (38). Mechanical engagement between the advancing cylinder and the fins derives from a cylinder projection (48) engaging a slot (26) at the rear of the fin, or a rolling contact between surfaces of changing curvature to ensure correct timing correlation. ADVANTAGE - Erection elements are more compact than the inflatable units used for known projectiles.
