Title: Manually operable metering syringe for liquids or plastic compositions, especially for dental purposes
IPC: G01F11/02
Filed: 1981-07-24
Abstract: The present invention relates to a manually operable metering syringe for liquids or plastic compositions, especially for dental purposes, which comprises a cylindrical body (1), a piston (4) provided with a threaded rod (3) and an internal screw thread part engaged with the threaded rod and detachable from the cylindrical body (1). Fig. 1 shows that this metering syringe, according to the invention, is distinguished in that the threaded rod (3) has at least one groove or flattened section (4) and that the piston part (7) is integrally connected with the threaded rod (3). The metering syringe according to the invention furthermore comprises a mounting and guiding member (2) which can be detached from the cylindrical body (1) and which has at least one passage opening (6) complementary to the cross-section of the threaded rod (3). In this detachable mounting and guiding member (2), a knurled nut (5) with a lefthanded thread is held and guided and, during rotation of this nut, upward and downward movement of the piston part (7) is possible in the cylindrical body (1) without the piston executing a rotary movement during this upward and downward movement. This results in the special advantage that tearing-off of the piston contents during back-aspiration is largely avoided. <IMAGE>

Title: Tanker vehicle
Inventor: KUHN ERNST DIPL ING
IPC: B60P3/22
Filed: 1981-10-12
Abstract: The invention relates to a tanker vehicle for transporting liquids or gases, in particular liquid gas, a fitting box for a fitting, in particular measuring fitting, being provided and at least one line being present between the tanker vehicle and the fitting box. Hitherto, the fitting box and vehicle have been securely connected to one another in such a way that separation can only be carried out for repair and maintenance purposes, that is to say not during operation, and special aids and tools are essential. Under certain application conditions, for example if the tanker vehicle is to be completely emptied at the customer's premises, the fitting box is however superfluous. In order to achieve an economical application of the tanker vehicle and optimum utilisation of the transport capacity, it is proposed according to the invention that the fitting box be arranged on the tanker vehicle by means of quick-coupling and quick-release mounting elements, that mutually assigned parts of a coupling for the line are provided on the fitting box and on the vehicle and that movable compensation elements, in particular rotary joints or compensators, are provided for the line. <IMAGE>

Title: Process for the water-saving cooling of a washing liquor
Inventor: GRAF RICHARD DIPL ING
IPC: D06F35/00
Filed: 1981-10-21
Abstract: The washing liquor which, at the end of the washing programme, is contained in the tub of an automatically controlled drum-type washing machine having a level control at an upper and a lower level has to be cooled gradually, because too rapid a cooling of the washing liquor would precipitate the phosphates contained in it. In the known oscillating rinsing, the procedure is that, when an upper level is reached, the water supply is switched off and the liquor discharge switched on. After a lower level is reached, these operations are reversed again. The liquor cooling and dilution is therefore incomplete and necessitates too high an outlay of water in order to achieve the desired purpose. This disadvantage is to be avoided. According to the solution, when the upper level of the washing liquor diluted by cold water which has flowed in is reached, the washing drum is moved for 5 to 30 seconds, and thereafter the washing liquor is discharged as far as the lower level and then supplied again until the upper level is reached.

Title: Process and equipment for separating a gas mixture, such as air, by adsorption
Inventor: AMITANI TATSUO
IPC: B01D53/04
Filed: 1981-12-21
Abstract: A process for separating a gas mixture by adsorption is described, in which adsorption and desorption steps are carried out repeatedly and in mutually offset cycles in a plurality of adsorption columns, and which is characterised in that, to initiate a desorption step, a gas mixture supplied by or discharged from an adsorption column, in which the adsorption has been completed during a primary (first) pressure-lowering period, is transferred to another adsorption column, whose pressure has, after completion of the desorption step, been increased by means of a non-adsorbed gas constituent, supplied as a result of the low-pressure adsorption, and/or a gas mixture, supplied or discharged during the primary pressure-lowering period, to a value between the adsorption pressure and desorption pressure, in order to carry out a low-pressure adsorption step, during which the adsorbable gas constituent of the gas mixture is adsorbed, while a pressurised gas mixture, supplied during the primary pressure-lowering period, of low concentration of adsorbable gas constituent can be effectively used. The invention also relates to equipment for carrying out this process.

Title: Pneumatic central-locking system for the doors, flaps or the like of a motor vehicle
Inventor: HEIMBRODT KLAUS-J
IPC: E05B65/38
Filed: 1982-06-19
Abstract: The invention relates to a pneumatic central-locking system for the doors, flaps or the like of a motor vehicle, having a vane-cell pump as a pressure source. To make it possible to achieve a rapid pressure equalisation in the working spaces and working lines of the pneumatic system, there is an automatic vane return which takes effect when the pump is at a standstill and which brings about a fluidic flow short-circuit through the vane-cell pump. This return can be obtained pneumatically or mechanically by rotating the pump rotor once at low speed or by increasing the retaining forces or introducing return forces.
