Patent DE-3302467-A1 (DE)
Title: Pair of rails for adjusting vehicle seats
Inventor: GRIESEMER ALBERT
IPC: B60N2/07
Filed: 1983-01-26
Abstract: A pair of rails for adjusting vehicle seats is to be improved with respect to the expenditure in terms of manufacture and assembly and also in terms of its constructional length. Whilst the known pairs of rails have rollers or the like which in each case can be moved individually between their own stops, the degree to which said rollers can approach one another being restricted by said stops, the invention proposes an arrangement of the rollers 3, 4 in a common cage 5 at a constant distance from one another. By means of this positive guiding, the roller 3 or 4 which is respectively the rear one viewed in the direction of movement can move on into the central region of the lower rail 1 together with the cage 5, which means the upper rail 2 has a larger displacement path. In other words, a specific displacement path can now be achieved with a shorter constructional length. Another consequence of this is that the expenditure in terms of manufacture and assembly is lowered. <IMAGE>
Patent DE-3305815-A1 (DE)
Title: Control valve for hydraulic systems
Inventor: GROB ALFRED
IPC: F04B49/10
Filed: 1983-02-19
Abstract: The control valve for hydraulic systems is intended as a shutoff or relief valve for a pump (19) and has a pressure-limiting valve (28) and a pressure-holding valve (39) positioned downstream of the latter. If a high pressure is to be reduced for a short period, the pressure-limiting valve responds and relieves the pump. If the overload phase persists for a prolonged period, a control slide (43) is moved into a position in which the pump is relieved directly to the return at low delivery pressure. The movement of the control slide (43) is to take place in a delayed manner. This is achieved by the fact that a spool (49) is formed in the said control slide and the said spool has rotation imparted to it by a flow of pressure medium flowing via bores (60, 61). At each rotation, a restriction bore (65) is connected to the delivery side of the pump and a connection is thereby established to a chamber (47) which displaces the control slide (49) into the shutting-off position counter to the force of a compression spring (40). <IMAGE>

Patent DE-3310250-A1 (DE)
Title: Set-down device for dough pieces
Inventor: SCHROEDER REINHARD
IPC: A21C9/08
Filed: 1983-03-22
Abstract: There is a set-down device, in which there is arranged at a distance above a product carrier (26) a belt conveyor (4) with an end deflection (19), which can be moved forwards and backwards, of a conveyor belt (14) and the spacing between end deflection and product carrier during the backward movement is smaller at least in the front region of the product carrier than the spacing during the forward movement. At the same time it is desirable that, in the set-down device, the operational reliability is increased and the spacing increase is accelerated. This is achieved in that the height position (28, 39) of the end deflection (19) of the conveyor belt (14) and of the product carrier (26) relative to one another can be set to a smaller spacing for the backward movement and to a greater spacing for the forward movement by means of a height-adjusting device (28, 39), having a separate drive (33, 43), and control stops (13, 11; 46, 47). Switching over to a smaller spacing and to a greater spacing takes place accurately, rapidly and operationally reliably. <IMAGE>

Patent DE-3321301-A1 (DE)
Inventor: HERRNRING GUENTHER DR PHIL
IPC: B43K5/10
Filed: 1983-06-13
Abstract: An ink supply system for writing instruments which operate with liquid ink. The writing instrument has a large-volume ink reservoir which communicates via a recharge valve with a small-volume ink reservoir which is adjacent to the writing element. The transmission of ink from the large-volume ink reservoir to the secondary reservoir is controlled by a sensor as a function of the quantity of ink which is present in the secondary ink reservoir. In order to simplify the recharging of the ink, and to be able to operate with the least possible electrical energy, the present invention utilizes as a recharge valve a tube pump which is rotatably driven by an electric motor and also can generate the pressure necessary to convey the ink to the secondary ink reservoir.
