Patent DE-3143033-A1 (DE)
Title: Electrical reversal of a linear high pressure pump
Inventor: HILDEBRANDT ROLF
IPC: F01L25/08
Filed: 1981-10-30
Abstract: According to the invention, when using a linear high pressure pump for pumping a pressurised medium the working movement of the working pistons of the primary and secondary cylinder, which are coupled together, is reversed by electrical reversal. On reaching the respective limit position a control signal for the actuation of an electromagnetic control unit of a directional control valve is triggered by electrical pulse generation, for example by initiators. Very short switching times are achieved by this reversal, so that no losses or pressure fluctuations occur. This results in a continuous, pulsation-free delivery of a working medium, for example in the case of paint spraying or preservative units.

Title: Scissors, in particular hair-cutting scissors
Inventor: TAKAHASHI FUKUTARO
IPC: B26B13/24
Filed: 1981-11-12
Abstract: Scissors, in particular for employees in hairdressing salons and beauty parlours. Fixed in the region of the rear ends of the cutting edges of the two scissor blades is, on at least one inner face of one cutting edge, a sliding or contact element of high strength and low friction. As a result, in scissors whose blades possess a high cutting quality over the entire length of the cutting edges owing to the, in each case, inwardly bent cutting edges clamped to one another by the common bearing bolt, the ease of operation is substantially improved over comparable scissors, without impairing the high cutting quality. In addition, the scissors according to the invention have a substantially longer life compared with the known scissors. The material for the sliding or contact elements can advantageously be a tetrafluoroethylene plastic.

Title: Delivery container
Inventor: SPORI ARTHUR
IPC: B65D83/04
Filed: 1982-04-26
Abstract: Arranged inside the container body is a two-part insert (2, 3) which has an immovable part (2) and a sliding part (3). The sliding part (3) can be actuated from the outside of the container and can assume two positions. In the starting position, a channel (11) arranged in the sliding part is aligned with an apportioning region (6) in the immovable part (2). The tablets (7) thus pass through a funnel-shaped inlet (5) into the apportioning region (6) which is preferably constructed to receive one tablet. When the sliding part (3) is moved into its second position counter to the force of a restoring spring (10), the apportioning region (6) opens towards the outside, but is at the same time closed towards the inside by the displacement of the channel (11) so that only the contents of the apportioning region are delivered. The delivery container accomplishes an apportioned delivery in a simple manner, it being possible to continue using conventional container shapes. <IMAGE>

Abstract: A power-assisted brake system for road vehicles with hydraulic wheel brakes is explained, in which a separate brake circuit is provided for each vehicle wheel. For each brake circuit a separate pressure accumulator is provided, from which pressure is applied to the wheel brake. This pressure accumulator and an electrically actuatable solenoid valve arrangement, by means of which the wheel brake cylinder can be coupled to the pressure accumulator in pressure build-up phases, connected to the reservoir of the brake system in pressure reduction phases and can be shut off from both the pressure accumulator and the reservoir in pressure maintaining phases, are combined with the brake calliper of a wheel brake, assumed to be a disc brake, to form a compact unit. For proper actuation of the solenoid valve arrangement, an electronic control unit is provided, which from a comparison of reference value signals with actual value signals characteristic of the kinetic state of the vehicle wheel generates the control signals suitable for rapid matching of actual and reference value for the braking deceleration. The pressure accumulator can be charged by means of a separate accumulator charging pump provided for each brake circuit. The accumulator charging pumps are designed as small plunger pumps, which can be driven by the vehicle wheels.

Title: Glow ignition device for an internal-combustion engine
Inventor: LINDER ERNST DIPL ING
IPC: F02B19/14
Filed: 1983-05-17
Abstract: The glow ignition device (42) has two rings (43, 44) made of ceramic material, which bear on one another and inside enclose an annular tunnel (71) and adjacent to a cylinder head (50) of an internal-combustion engine (48) are built into an extension (54), which is located on the upper end of a cylinder (49). A plurality of transfer ports (70a) which open into a main combustion chamber (52) located above a piston (51) moving up and down in the cylinder (49), emanate from the tunnel. An electrically heatable wire coil is inserted into the tunnel as glow ignition device (45). On the compression stroke of the piston (51) combustible mixture is forced through the transfer ports (70a) into the tunnel (71) where it is ignited by means of the glow ignition device (45). Because a plurality of transfer ports (70a) is arranged on the periphery of the main combustion chamber (52), the residual part of the mixture there is essentially ignited simultaneously at a plurality of points by means of ignition torches emerging from the transfer ports. This results in a very rapid reaction of the mixture which reduces the fuel consumption and the pollutant content in the exhaust gas. <IMAGE>
