Title: Gearchange control arrangement for an automatic transmission
Inventor: UMEZAWA MITSUO
IPC: F16H61/10
Filed: 1981-06-02
Abstract: A gearchange control arrangement for an automatic transmission for motor vehicles comprises a planetary reduction gear and a brake band for changing the transmission ratio. The arrangement serves to apply the brake band gradually. The arrangement comprises a servopiston, a piston rod attached to the servopiston and the brake band and a collecting-chamber piston which is inserted with the ability to slide axially in the bore of the servopiston. The servopiston is preloaded by a first spring which serves to return the servopiston in order to release the brake band. The collecting-chamber piston is preloaded by a second spring at one end of the bore of the servopiston. Oil chambers for the application and release of the brake band are formed on opposite sides of the servopiston and a collecting oil chamber is formed between the end of the bore and the collecting-chamber piston. Pressurised oil is fed to the application oil chamber, thereby moving the servopiston, counter to the first spring, in the direction of application of the brake band. The collecting-chamber piston then moves by a certain stroke counter to the second spring. The collecting-chamber piston then comes into engagement with the servopiston, with the result that the two pistons move together to tighten the brake band. <IMAGE>

Title: Primary mirror for celesial (astronomical) telescopes
Inventor: PETERSEN KLAUS
IPC: G02B26/08
Filed: 1981-09-02
Abstract: The prior art is reflecting (mirror, catoptric) telescopes having a fixed focal point, which are produced from ground glass elements and provided with a reflective layer. The object of the invention is to reduce the production costs for a reflecting telescope by using a rotating liquid mirror, and to undertake a shift in focal point by varying the rotational speed. It is known that a precise paraboloid of rotation is formed by rotating a liquid. According to the invention, the object is achieved when the primary mirror (5, Fig. 1) consists of a rotating liquid. The light beams (1) are projected via the planar auxiliary mirrors (2 and 4) onto the rotating primary mirror (5) which consists of a round vessel with liquid. The focused light beams are reflected to the focal point where a plane (flat) mirror (6) leads the light beams to the eye (8) of the observer via lenses (7). The change in focal point can be undertaken by a motor (9) whose rotational speed can be adjusted and which drives the liquid mirror (5) via V-belts (10), a bearing (11) and a shaft (12). <IMAGE>

Patent DE-3140298-A1 (DE)
Title: Linear bearing unit
Inventor: TERAMACHI HIROSHI
IPC: F16C29/06
Filed: 1981-10-10
Abstract: The invention makes available an improved linear bearing unit which exhibits no loss of operating performance despite the omission of a conventional cage. The bearing housing of the linear bearing unit contains a plurality of holes or bores for non-loaded balls and semicircular deep raceway grooves, a larger contact surface between the loaded balls and the raceway grooves thereby being obtained. The upper raceway grooves enclose between them a right angle relative to the centre of the bearing unit, thereby ensuring that there is no edge loading (which is also referred to as critical loading at the edge part). A prestress (or preload) on the loaded balls in some of the four raceway grooves can furthermore be employed. According to another aspect of the invention, an outer sleeve is built into the bearing housing, the said sleeve containing or having on its inner wall four raceway grooves. Side covers (or return/deflection plates), which are secured firmly on both front faces of the bearing housing, contain annular grooves which correspond to annular projections on both end faces of the outer sleeve, and U-shaped concave parts, which are in alignment with four raceway grooves situated thereon, which serve to reverse the movement of the loaded balls, and tongue parts on the innermost end of the side covers.

Title: Front power take-off shaft with hydraulic pump drive for agricultural tractors
Inventor: GOEPPEL ALOIS
IPC: B60K17/28
Filed: 1982-04-14
Abstract: The object of the invention is to create a device which allows a hydraulic pump to be operated at the front with simultaneous driving of a front transmission from the engine at the front in order to achieve a multiple utilisation of the tractor, especially of the flange point of the crankshaft at the front. The invention proposes to achieve this object by incorporating a front transmission into the front axle bearer or the like of the trailer, which transmission essentially comprises a transmission housing, an input shaft and output shaft, a driver pulley with V-belt groove being arranged directly on the input shaft or by way of components, with a holder welded or bolted on the transmission or on the front axle bearer or the like, which holder carries the hydraulic pump with bolted on V-belt pulley flange-mounted in a holding bracket or the like and offset parallel to the input shaft. The drive of a hydraulic pump comes from the driver pulley which is supported directly or by way of components on the input shaft and on which a cardan shaft is flange-mounted directly or by way of connections as drive element to the engine, to the V-belt pulley of the hydraulic pump. To date it has been usual to mount attachments on the rear end of the vehicle where a power take-off shaft is provided for their drive. In many instances, however, it is desirable to carry out a plurality of operations in one process, such as, for example, driving a beetroot topping machine at the front and to dig with a towed digger or to drive an additional hydraulic pump, for external hydraulic systems on front attachments.

Patent DE-3222021-A1 (DE)
Title: Board game
Inventor: JOACHIM EUGEN
IPC: A63F7/02
Filed: 1982-06-11
Abstract: In a board game having a sloping or inclined plane, the path over which balls or the like have to run is divided into two sections in order that said balls can be made to run out of the starting region into a target region. In this arrangement, on the one hand, the balls run over the path to be covered at random and without intervention on the part of the players but, on the other hand, there is to be an opportunity, within certain limits, for a possible change in direction of the balls. In a first section of said path, there are stationary obstacles, e.g. stationary pegs distributed over the running surface, which have to be passed without being able to adjust the course of the balls. In the second section, on the other hand, there are movable obstacles, e.g. likewise in the form of pegs, the position of which can be changed from the outside by means of a lever device and which can divert the path of the rolling balls or the like in a specific manner. This is achieved in that said pegs can be correspondingly altered by means of a lever arrangement in accordance with the wishes and the skill of the player. The balls then run in each case into a basket-shaped recess which serves as a catching device. This catching device is provided with symbols according to which a winner is declared, in dependence on the game rules which have been stipulated.

Patent DE-3232283-A1 (DE)
Title: Self-protection and signalling apparatus
Inventor: WEIDINGER HEINRICH
IPC: F41C3/04
Filed: 1982-08-31
Abstract: The initial use of a 9 mm smoke and flash (bang and gas) calibre munition opens up a wide range of applications for the user of the apparatus. 1) A particularly loud bang in the case of bursting cartridges as a result of the large calibre and the short movement of the combustion gases. 2) For the same reason, a very great effect when gas cartridges are used. Item 1) is advantageous for the emission of signals, for example rescue, alarm or starting signals. Item 2) is advantageous when defending against criminal attacks, such as a raid, break-in or violation (rape, murder, mutilation). Easy operation and, at the same time, a safe method of carriage permits immediate operational readiness, as a result of a sensibly arranged double-action trigger. The capability for use as a signalling apparatus is further enhanced by the allocation of a pocket lamp, this assembly being accommodated, in particular, inside the apparatus body. The loading head is set up for accommodating both the 9 mm cartridges mentioned above and for 15 mm calibre pyrotechnic ammunition. The double-action trigger is particularly important, and acts on the sear (striking lever) by means of a separate driver. A further feature is the handy shape and the small size of the apparatus. Finally, the easy manufacturing capability, the small number of individual parts (components) and their simple and hence cost-effective assembly are to be emphasised. The drawing in Figure 1 provides a summary of this. <IMAGE>
