Patent DE-3324756-A1 (DE)
Title: Powered screwdriver
Inventor: DUERR PAUL
IPC: B25B23/00
Filed: 1983-07-08
Abstract: The screwdriver has a holding device for screwdriver bits (4), the holding device possessing an axially displaceable adjustable sleeve (5) surrounding a receiving shank (3). On retracting the adjustable sleeve (5) towards the tool casing (1), a locking ball (6) which engages in a recess (4c) can move radially outwards into a recess (5a) of the adjustable sleeve (5). As a result, the screwdriver bit (4) is released and can be pulled out of the receiving shank (3) in the direction opposite the movement of the adjustable sleeve (5). After inserting a new screwdriver bit (4), the adjustable sleeve (5) is again brought into locking position by a compression spring (7). <IMAGE>

Title: Radial piston machine as an evolvent machine
Inventor: NEUHAUS HERMANN ING GRAD
IPC: F04B1/10
Filed: 1983-12-27
Abstract: Technical problem: The individual pistons of a radial piston pump or a motor generate a sinusoidal volume flow or a sinusoidal torque. Solution to the problem: The evolvent radial piston machine according to Figure 1 is controlled, in the operating range which generates the power stroke, by a curve which has the shape of an evolvent, and in the non-pressurised range is of sinusoidal shape. As a result, the volume flow or the generated torque of a cylinder piston during the power stroke is constant at all times. The sum of the generated volume flows or the generated torques of all the cylinders set in the operating range is uniform and constant at all times. Application: Hydrostatic transmissions with low rotational speeds. <IMAGE>

Title: Prandtl tube for non-stationary speed measurement
Inventor: KLAS ERNST DIPL ING
IPC: G01P5/165
Filed: 1984-06-08
Abstract: The present invention relates to a Prandtl tube consisting of an elongated member (1, 8) which is of streamlined construction and has an opening (3) on the front side (2) and one or more openings (10) on the sides, the openings (3, 10) being connected to a differential pressure measuring device, the differential pressure measuring device being a small differential pressure transducer (6) which is integrated between the front opening (3) and side openings (7) in the elongated member (1, 8). The preference in this arrangement is piezoresistive pressure transducers which can, if necessary, be provided with a temperature compensation circuit. Such a head pressure meter according to the invention can be of very small construction and is also suitable as a measuring head for a probe. Since no pressure-conducting leads are provided, but only electrical leads, there is a resultant ease of manipulation and, due to the reduction in the measurement volumes, a higher measurement accuracy and lower inertia. <IMAGE>

Title: ISO building-block system
Inventor: KIRCHBACH DIETER
IPC: E04B2/44
Filed: 1984-11-24
Abstract: The invention relates to an ISO building-block system for cold insulation, heat insulation and sound insulation. The system can be used to build walls, in particular in the case of houses, halls and buildings of all types, in accordance with the conventional and known construction methods. An insulating layer is formed in an ISO building-block system by filling the existing cavities on the outer sides of each ISO building-block with expandable insulating material. After solidifying, said insulating layer forms, throughout the masonry structure, a cold insulation, heat insulation and sound insulation which cannot be seen from outside or inside. As has been the case hitherto, a masonry structure constructed by the ISO building-block system can be plastered inside and outside. Since the insulation is not exposed to weathering, expenditure in terms of repair and maintenance is not necessary. Time and materials which have been expended in order to provide interior or exterior insulation used up until now are greatly reduced by the ISO building-block system.

Title: Process for producing a moulding from thermoplastic and thermoset
Inventor: TEUSCHLER HANS-JOACHIM DR
IPC: B29C70/84
Filed: 1985-01-18
Abstract: The invention relates to the production of such mouldings by conventional compression moulding and injection moulding processes taking into account material-dependent pressure, temperature and time conditions. The aim of the invention consists in reducing the outlay for producing the mouldings and in providing mouldings having improved functional properties. The object of the invention is to develop a process for producing the mouldings with a direct, undetachable end gap-free connection between the plastic components. This object is achieved according to the invention by inserting thermoplastic sections into a mould, forcing flowable thermoset into the space delimited by the thermoplastic sections, deforming the softening thermoplastic sections by means of the thermoset and forcing them into the contours of the mould which is preheated to the curing temperature of the thermoset. These mouldings are used as components in machine construction and in precision instrument engineering and as high-voltage resistant insulating bodies. <IMAGE>

Title: Sterile safety-filling and removal system for liquids
Inventor: STOK SRECKO
IPC: B67D3/04
Filed: 1985-09-30
Abstract: Sterile safety-filling and removal method for liquids. In the case of such a method, liquids, such as fruit preparations, fruit juices, extracts of the latter or the like, are poured into containers, such as special steel, stainless or plastic, or in BAG-IN-BOX containers and are delivered to the customer. This process means that there is a danger of reinfection in the event of improper handling, and it is often difficult to prove the cause of damage once it has occurred. In order to remedy this unsatisfactory situation, it is proposed that the filled container 1 is provided with two valves 2 and 3, which are arranged one behind the other, for the outlet and to insert between the said valves 2 and 3 a runback blocking device 4 which prevents the liquid from flowing back into the container 1 while the liquid is being removed. Furthermore, the assembly parts, such as union nuts 5 and operating levers, such as handles 6 and 7, are locked by means of locking devices 6, 8 and 9 and the latter are secured by means of seals 10. <IMAGE>
