Patent DE-3319838-A1 (DE)
Title: Bicycle pedal
IPC: B62M3/10
Filed: 1983-06-01
Abstract: In a bicycle pedal having two cross-webs (1) and two side parts (4), the side parts (4) are guided with one end section (3) in each case through a slot (8) in the cross-web (1). Subsequently, the end section (3) is bent around through 90 DEG  and lies in an indent (2) of the cross-web (1) in a positively engaging manner. By virtue of this design, the side parts (4) are particularly well secured against rotation in relation to the cross-web (1). In addition, there are no edges protruding out of the cross-web which could lead to injuries. <IMAGE>

Title: Hydraulic, controllable shock absorber with a damping piston fixed on a hollow piston rod
Inventor: SCHMIDT RUDOLF
IPC: F16F9/46
Filed: 1983-09-22
Abstract: The object of the invention is to improve an electrical control of the damping forces in a shock absorber so that different characteristics of the damping forces can be obtained in various piston speed stages. To this end the valve disc base has an opening for the radius rod, so that an additional and closable oil passage is created through an upper and lower flow aperture. Depending on the working position of the radius rod and hence of the control piston either low damping forces in the middle piston speed range and high damping forces in the low piston speed range or high damping forces in the middle piston speed range and low damping forces in the low piston speed range can be achieved.

IPC: B62D63/06
Filed: 1984-02-23
Abstract: The special characteristic of the trailer with three axle assembly is that the maximum overall wheelbase of the three axles is less than 1000mm and is thereby legally registered as a single axle vehicle. The trailer is equipped with a specially developed axle assembly which provides for combining of the respective lefthand and righthand three wheels into triangular units by means of trailing arms, semi trailing arms and transverse links in such a way that optimum ground adjustment of all wheels is ensured.

Abstract: PCT No. PCT/CH85/00068 Sec. 371 Date Dec. 23, 1985 Sec. 102(e) Date Dec. 23, 1985 PCT Filed May 1, 1985 PCT Pub. No. WO85/05183 PCT Pub. Date Nov. 21, 1985.The invention relates to a process for measuring the characteristics of test articles made from plastic, particularly polyethylene or polypropylene, to establish whether they are made from non-regenerated, regenerated or optionally a similar plastic which has been regenerated to a certain extent by the infrared spectrometric measurement of the transmission-absorption in the carbonyl group band range of the plastic. According to the invention, the transmission-absorption is measured in the carbonyl group band range at least two different thicknesses of the same plastic and the thickness dependence of these measurements is used as a measurement criterion. The invention is more particularly used on bottle crates or other large injection moulded articles and can be used for classification preferably with sorting according to ageing criteria, also in the case of test articles made from regenerated material, as well as for the selection of old crates suitable for producing regenerated material. The invention also relates to infrared spectrometric means suitable for performing this process.

Filed: 1984-06-27
Abstract: A screw press is described, which is distinguished by a special reversing device. The screw of the press is guided in a ram recess so as to be sealed against flowing materials at its lower end, so that a first chamber, the volume of which can be modified and which contains a flowing material, is formed between the screw nut and the lower end of the screw. During the operating stroke of the ram of the press, the flowing material situated in this chamber is forced out into a second chamber, where it exerts pressure on a flexible device. The energy stored in the said device is used to reverse the ram. <IMAGE>

Patent DE-3428790-A1 (DE)
Title: Contactless photoelectric position transmitter
Inventor: PINGEL GERHARD DIPL ING
IPC: G01D5/34
Filed: 1984-08-04
Abstract: The invention relates to a contactless photoelectric position transmitter which can be preferably used for control purposes in connection with analog actuating drives. An economic and technologically simple solution of a photoelectric position transmitter is to be created in which dimming elements are arranged in the beam path between the radiation transmitter and the radiation receiver, which elements supply exactly reproducible output variables and have very low mass in order to achieve fast speed for control purposes. This object is achieved by the fact that two polarisation elements are arranged adjustably with respect to one another in the beam path of the radiation transmitter and the radiation receiver of the photoelectric position transmitter. The positions of the points of rotation of the polarisation elements can deviate from one another. The planes of polarisation of the polarisation elements can take up any angular positions within the angular range of 90 DEG . The change in photocurrent of the radiation receiver is detected via an evaluating circuit and provided as output voltage. The invention can be particularly advantageously used in control loops in conjunction with analog actuating drives or as a contactless actuating resistor.

Title: Apparatus and method for setting the backlash-free bearing arrangement of a rotatable component
Inventor: OBERMAYER HEINZ
IPC: G01M13/04
Filed: 1984-10-03
Abstract: To set the bearing pretension of a rotatable component (1, 2, 3, 4), a press is used in which the component, with pressing bushes (18) pushed onto its spindle (1), is clamped in place between a plunger (9) adjustable under the action of force and a rigid base (5, 6). An eccentric drive (12, 13, 19, 20) which can be rapidly relieved of load is provided for applying the press-in force. During a preadjustment, the component is driven via its drum (3) by a drive device (23, 24, 25) to simulate the operating state and the current consumption of the drive device (23, 24, 25) is used as a control variable for the coarse setting of the bearings. For the fine setting of the bearings, a device (30, 31, 32) is used for measuring the static breakaway force as a measure of a defined bearing pretension. To check the bearing setting, a frequency analyser (29) is connected via an acceleration sensor (27) to the rotating component. Use in all rotatable components in which high positional accuracy is demanded. <IMAGE>
