Title: Carousel with facility for making double or multiple jumps
Inventor: MUELLER JUN PAUL
IPC: A63G1/26
Filed: 1981-04-13
Abstract: The invention is characterised by the fact that two or more passenger platforms (Fig. 4/2) are mounted on one or more centrally mounted carousel cross arms (Fig. 3/1) which are arranged in a cross or star shape and are driven electrically or in another manner. The passenger platforms (Fig. 3 + 4/2) can or are driven on the right-hand or left-hand side, independently of each other, electrically or in another manner. The jumping is achieved by virtue of the fact that the carousel cross arm or arms (Fig. 3/1) is (are) raised by hydraulic lifting movements (Fig. 3/6) or in another manner, resulting in the typical movements of jumping, hopping or rocking. The particular type of design of the associated entrance and exit of the passengers, the special efficient service by a particularly arranged pay desk and the specially designed rear-wall brake car (Fig. 3/4) as well as the carousel cross arm or arms which can be unfolded (Fig. 2/9) and the reinforcing ribs arranged in an articulated manner (Fig. 2/10 + 11) for the purpose of rapid construction and dismantling and frictionless transportation, the central part of the carousel being transported on a conventional intermediate two-wheeled car, which can be mounted and dismounted (Fig. 3/7), are likewise the subject-matter of the invention. <IMAGE>

IPC: E03C1/20
Filed: 1981-06-10
Abstract: The invention relates to a sanitary article, the seat bath, called a "bidet" for washing and douching the intimate parts of the human body. In general, the commercially available bidet is a quite a heavy and expensive article of use which requires its own standing surface in the sanitary area. Alternatively, supplementary constructions and accessories for lavatory bowls, with separate supply lines for the lavatory flushing water and the heated bidet water, have been proposed. Even these designs are technically complex and costly. According to the invention, normal bathtubs with a hand-held shower can be used as a bidet. For this purpose, a holder is provided for the hand-held shower, which holder is mounted on the wall of the bathtub. The edge of the bathtub serves as a seat surface for the user. The shower holder can be connected to the bathtub fixedly or releasably. In the exemplary embodiment according to Figures 1-3 of the application, the reference numeral (1) denotes the inner wall of the bathtub, (2) denotes the hand-held shower, (3) denotes the shower shaft, (4) denotes an elastic jaw part, and (5) denotes its foot part which is fixed to the inner wall (1) of the bathtub by means of a self-adhesive coating on the underside. <IMAGE>

With the aid of programmable memories (ERNPROM, FRNPROM), a speech processor (Spr-Pr) interworking with the programmable control device (P-St) and a speech memory (Spr-Sp), announcements of changed telephone numbers can be notified to a calling subscriber as well as instruction texts corresponding to the relevant special service feature. <IMAGE>
Patent DE-3125541-A1 (DE)
Title: Device for the frictionally locking connection of two structural parts
Inventor: LAUMANN WERNER DIPL ING DR
IPC: B01J3/00
Filed: 1981-06-29
Abstract: The device is intended to connect, in a frictionally locking manner, two structural parts which, when operating, are at an operating temperature which differs considerably from a mounting temperature and, at the said operating temperature, are to be held together at a predetermined tensioning force by means of at least one bracing element. In order to ensure uniform bracing of the structural parts without expensive mounting tools being necessary, the invention provides that, for the bracing element (6), use is made of a material, the mean expansion coefficient of which differs from the mean expansion coefficient of the material of the structural parts (2, 4; 3, 5) by such an amount that the tensioning force is adjusted at least largely automatically when the temperature changes from the mounting temperature to the operating temperature. The structural parts (2, 4; 3, 5) may, in particular, be portions of a vacuum housing of a superconducting magnet. <IMAGE>
Patent DE-3131319-A1 (DE)
Title: Control device for a hydrostatic travel drive
Inventor: NONNENMACHER GERHARD DIPL ING
IPC: B60W30/18
Filed: 1981-08-07
Abstract: The control device for the hydrostatic drive with primary and secondary unit has a feed pump for the provision of the pressure medium for the transmission control, feed pump and primary unit being driven by a common prime mover, especially an internal combustion engine. In the delivery line of the feed pump a measuring throttle (18) and a flow control valve (48) are connected in series. The pressure drop across the measuring throttle is used for the adjustment of the primary unit (10), the secondary flow of the flow control valve (58) for adjusting the secondary unit (13). The flow control valve is adjusted from the outset so that a secondary flow is produced only at - or close to - the maximum speed of the prime mover. This flow can be restricted by further operation of the drive pedal (57) so that in the control circuit (51) for the secondary unit a pressure is built up, which by way of the control element (52) adjusts the primary unit to a smaller capacity. It will be perceived from this that a return of the secondary unit occurs only when the prime mover has almost reached its maximum speed and the primary unit its maximum displacement. <IMAGE>
