Inventor: RUSINOV MICHAIL MICHAILOVIC
IPC: G02B13/02
Filed: 1980-10-21
Abstract: The Galilean telescopic system for binoculars consists of single collecting meniscus front (1) and second (2) lenses and a dispersing meniscus rear element (3) used as the eyepiece at a distance (8) behind the lenses (1,2), all being rearwardly concave. The element (3) consists of a cemented (7) doublet whose lenses (4,5) have approximately equal refractive indices but different dispersion. The glass of the lens (5) nearest the exit aperture (6) of the system has considerably lower dispersing power than that of the lens (4) further from that exit. The air space (8) is defined as a specified function of the rearward focus, the magnification of the system and the curvature of the forward face of the element.

Title: Transfer and setting-down apparatus for transferring brick mouldings deposited in a row on one stacking surface onto another stacking surface
IPC: B65G61/00
Filed: 1981-01-22
Abstract: The invention is concerned with a transfer and setting-down apparatus for transferring brick mouldings (2) deposited in a row on a setting-down surface (1) onto a stacking surface according to a selective setting-down program. This transfer and setting-down apparatus has a turning frame, mounted rotatably through at least 180 DEG about a central axis of rotation (3), with two suction beams (4), forming frame longitudinal sides parallel to one another in a vertical plane, and with suction plates adjustable on the suction beams (4) into selected setting-down positions in the beam longitudinal direction. The suction beams (4) are mounted rotatably in the wing cheeks (6a, 6b) forming the transverse sides of the frame. The wing cheeks (6a, 6b) are rotatably mounted, by means of a hollow profile (7) connecting them and having a vacuum connection and suction conduits (8) leading to the suction plates (5), on the axis of rotation (3) arranged between two bearing cheeks (9a, 9b). A rotary drive (10) for the turning frame is supported on one bearing cheek (9a) and a pivoting drive (11) for the suction beams (4) is supported on the other bearing cheek (9b). The two bearing cheeks (9a, 9b) are suspended on a crossmember (12). <IMAGE>
Patent DE-3106178-A1 (DE)
Inventor: NADAS JULIUS
IPC: B61H15/00
Filed: 1981-02-19
Abstract: The device automatically adjusts the slack in the brake linkage of railway vehicle during the braking process and has two telescoping rod members one of which is connected with a brake motor and the other is connected to the brake linkage. A nut, nonrotateably mounted on the brake linkage rod member, is threaded upon a rotateable spindle shaft which is axially moveable a limited distance within the brake motor rod member and is connected to this rod member by a control clutch. When the control clutch is stressed by torque, the control clutch member will become disengaged from the brake motor rod member to permit a relative adjustment between the two rod members to overcome any slack. When slack is overcome, a rotary clutch between the threaded spindle and the brake motor rod member will be engaged so that braking force can be transmitted between the rod members. A pretensioned spring stresses the brake motor rod member in the direction opposed to the braking force but does not exert any force upon the clutch control member.
Patent DE-3124661-A1 (DE)
Title: Mechanical seal for pressures acting from one side
Inventor: SONDERMANN KARL-JOSEF DR
IPC: F16J15/3208
Filed: 1981-06-24
Abstract: Sealing arrangements for pressures acting from one side, comprising a slip ring and a flexible clamping ring, are improved by the invention by the use, as a slip ring, of a plastic ring with its outer contour being of rectangular cross-section (1) which, facing the high-pressure side, has a wedge-shaped annular space (2) which divides the sealing ring into a bearing portion for the clamping ring and a sealing portion (9). The pressure exerted by the clamping ring (3) and the fluid pressure give rise to a sealing system which exerts only a low sealing pressure, due to the pretension of the clamping ring (3), when there is no fluid pressure present, while fluid pressure from the side of the sealing ring with the wedge-shaped notch produces a displacement of the sealing ring and of the clamping ring towards the flank of the groove and simultaneously expands the wedge-shaped annular space (2a), and the total contact pressure of the sliding sealing ring and hence the sealing effect is increased. According to the invention, the slip ring is advantageously made of polytetrafluoroethylene (PTFE) or some other fluorocarbon plastic (polymer) with a low coefficient of friction, either unfilled or filled with additives. <IMAGE>

With fastening belts of the inner basket, the injured person is securely held in his position on a vacuum mattress inside the inner basket and can be lifted without change with this vacuum mattress into the outer basket and can be removed from it. The slide basket is especially suitable for the transport of injured persons in underground mining.
Patent DE-3135345-A1 (DE)
Title: Sole for cycle racing shoes
Inventor: EPPLE FRANZ
IPC: A43B5/14
Filed: 1981-09-07
Abstract: A sole for cycle racing shoes (shoes for racing cyclists) has, disposed approximately in mid-sole, a fitting with a slot-shaped recess in order to ensure a safe hold of the shoe on the pedal of the racing cycle. The fitting has elongate holes for the purpose of adjustablity vis-à-vis the sole surface, and is screwed into the sole. With each elongate hole of the fitting there is an associated elongate guide which, however, is at right angles, or essentially at right angles, to the associated elongate hole. In the elongate guides there is in each case slidably disposed a threaded union bushing. The aforementioned configuration of the sole and the associated fitting makes possible an adjustment of the fitting and hence of the slot-shaped recess (transverse groove) located therein not only in the transverse direction but also in the longitudinal direction of the sole and also, in addition, in the diagonal direction. Finally, said configuration of sole and fitting also makes possible an angular adjustment of the fitting in relation to the sole surface. Said adjustability of the fitting in relation to the sole surface in all conceivable degrees of freedom is achieved by simple means. It makes it possible for the cyclist to set or adjust the fitting at any time according to his or her individual wishes until the best setting has been achieved for the slot-shaped transverse groove of the fitting relative to the corresponding transverse member of the pedal which engages into the transverse groove.

Title: Method for operating a charge transfer device provided with a preceding low-pass filter
Inventor: KNAUER KARL DR ING
IPC: G11C27/04
Filed: 1981-09-30
Abstract: In this method, successive amplitude values of an input signal are sampled in an input stage and supplied in the form of signal-dependent charge quantities to the transfer channel and then to the output stage of the charge transfer device. The aim is largely to remove input interference signals, the frequency of which differs from the frequency range of the useful signal to be transmitted by about the value of the clock frequency of the CTD or a multiple thereof. For this purpose, the input stage (EST) is operated at a higher clock frequency than the remaining sections of the charge transfer device. The application includes integrated filters, particularly transversal filters. <IMAGE>

Title: Process and apparatus for biological treatment of sludge
Inventor: SINNING BERNHARD DIPL ING
IPC: C02F3/00
Filed: 1982-10-28
Abstract: The invention relates to a process for the biological treatment of sludge in an aeration reactor 1, in which the sludge is treated in the aeration reactor 1 with air supplied via a gas feed line 4 and/or oxygen supplied via the gas feed line 4 as the treatment gas, during which the sludge is circulated with the aid of a circulation device 6 and in the course of which is kept at a mesophilic or thermophilic temperature range. To avoid heat losses and to reach the necessary process temperature without supply of external energy it is proposed that warm and moist exhaust gas from the aeration reactor 1, produced from the treatment with gas, is fed via an exhaust gas line 5 to a gas input device 8, which is arranged in the sludge feed line 2 of the aeration reactor 1, and passed into the sludge to be treated with gas. It is further proposed to pass the heated sludge withdrawn, following the treatment with gas, from the aeration reactor 1 via a sludge line 3, prior to further treatment, to a heat exchange device 9 to transfer the heat contained in the treated sludge to the sludge to be treated in the sludge feed line 2. <IMAGE>
