Inventor: SCHAPIRA JOSEPH
IPC: C23G1/06
Filed: 1979-10-04
Abstract: 1. Process for cleaning vehicles, by putting into operation, in an acid medium, notably at a pH less than 3, in the presence of at least one surface-active agent, preferably non-ionic or anionic, notably at ordinary temperature, an effective quantity of a mono- or dialkylphosphoric ester the alkyl group or groups of which each contain from one to three carbon atoms, characterized by the fact that simultaneously an effective quantity of at least one compound chosen from the alkanephosphonic acids and their esters with the formula :  see diagramm : EP0027083,P5,F3  in which R1 is an alkyl radical containing from one to eight carbon atoms, possibly substituted by at least one of the substituents of the group containing the halogens, the hydroxyl radical, other phosphonic groups and amino groups with the formula :  see diagramm : EP0027083,P6,F1  in which each of R2 and R3 , which can be identical or different from one another, represents a hydrogen atom or the significances of R1 , and each of R4 and R5 , which are identical or different from one another, represents a lower alkyl radical containing from one to four carbon atoms, or a hydrogen atom, is put into operation.

Title: Automobile door lock with forked pivot bolt engaging pin staple - uses roller to transmit forces from pawl which secures bolt at closure
IPC: E05B65/32
Filed: 1979-12-28
Abstract: The automobile door lock uses a recoil sprung forked pivot-bolt (4) engaging a post-mounted pin-staple (1), utilising a sprung pawl (7) to catch bolt (4) at closure. Door closure movement brings the pin and the bolt into contact and the bolt pivots to trap the pin in the fork. The pawl engages teeth (21,22) formed on bolt perimeter. A roller (13) is used to transmit pawl forces to the bolt, which is located by a curved pawl inlet (12), and is secured by an 'S' shaped spring (16) to pawl fulcrum pin (8). The arrangement obtains a relatively quiet lock action and reduces the force required to effect pawl disengagement. Alternatively, the roller may be mounted on an axle pin spanning two cheeks which constitute the pawl.

Title: Brine source for water softener regeneration - with salt and brine chambers sepd. by calcined clay partition
Inventor: EIERMANN RUDIGER
IPC: A47L15/42
Filed: 1980-11-17
Abstract: Brine source for ion-exchange water softeners in domestic appliances (esp. dishwashers) comprises a salt chamber sepd. from a brine chamber by a brine-permeable partition, with the improvement that the partition is made of calcined clay. The clay partition is permeable to dissolved salt but completely impermeable to salt crystals, thus preventing blockage of the line from the brine source to the ion exchanger.
Patent FR-2470068-A1 (FR)
Inventor: KOST HEINZ
IPC: B01F5/10
Filed: 1980-11-19
Abstract: In order to prevent deposits from forming in heterogeneous liquids, a deflecting body (10) is arranged in a container (1) above the container base (3). The contours of the deflecting body (10) are matched to the container casing (2) in such a manner that the flow cross section in the gap between deflecting body (10) and container casing (2) continuously decreases downwards as far as the discharge opening (4) and the liquid flowing off is thus continuously accelerated. In this way, intensive washing of the dead container zones (8') is also reliably effected. Turbulence-generating elements can further assist the intensive mixing of the liquid.
Patent FR-2470279-A1 (FR)
Inventor: BERGER XAVER
IPC: F16B13/12
Filed: 1980-11-26
Abstract: The expanding body (10b) of the plastic dowel (10) consists of expanding segments (14a, 14b) which are profiled on the outside and are separated from one another by a slot (13). The end section (11b), which is formed from the segments (14a, 14b), merges into a transition section (11a) with a cavity (12). Longitudinally offset perforations (17) are provided in the transition section (11a). Deformable webs (18) are located between the perforations (17) so that a wood screw which is to be screwed in here is guided better on a relatively long path. The expansion effect of the plastic dowel (10) is not adversely affected in this case.

Title: Fish scaling machine with multi-bladed friction rotor - employs air suction between blades of sinusoidal profile
IPC: A22C25/02
Filed: 1980-12-24
Abstract: The rotor has a horizontal, tubular core of annular cross-section which is rotated on its longitudinal axis. A series of evenly-spaced, radial blades are mounted on the core. The edge of each blade is flat and has a sinusoidal profile. Air is sucked through orifices into the core passage. The orifices are pref. located between the blades so that decompression in the edge profile gaps pulls down the scaled surface between edge crests. The tubular core is pref. slightly bi-concave in longitudinal cross-section.The machine is pref. equipped with a number of interchangeable rotors which can be easily changed to suit the scaling of different types of fish. Scaling can be carried out more quickly without leaving any uneven patches and without damaging the fish. The fish is left with a very smooth, clean, regular surface.
Patent FR-2498544-A1 (FR)
Title: Vehicle trailer braking circuit - incorporates damper between towing arm and master-cylinder to reduce jarring
IPC: B60T11/10
Filed: 1981-01-29
Abstract: The progressive brake for a trailer includes a spring (1) which compensates for the inertial force of the trailer during braking. The spring bears against a nut (2) which can be adjusted according to load. As the towing vehicle brakes, the towing arm moves against the action of the spring and drives a piston into a master-cylinder, forcing brake fluid into the wheel-cylinders to effect braking the trailer wheels. When the towing vehicle ceases braking, a damper (3) allows the towing arm tc return to its initial position slowly reducing jarring.
Patent FR-2499745-A1 (FR)
Title: Magnetic tape coded data recorder and tester - monitors error appearance during recording for corrective rewriting using parity bit generator
IPC: G11B20/18
Filed: 1981-02-12
Abstract: Increased density of coded data recording of enhanced reliability is achieved by checking the recording immediately after writing each coded pulse and each data byte. The circuit ensures the recording of marking and service sync pulses as well as provides the check of marking pulses on the magnetic tape. The faulty recording is re-recorded, and the check playback is carried out during the time interval between the consecutive cloded pulses using the same head as for the recording. The instant of correct recording is indicated by a market pulses, and a generator of byte parity digit is included with the amplifiers of recording and playback connected to registers. The coded signals are fed to recorder register formed by flip-flops for each track of the magnetic tape and linked to the byte parity shaper as well as to gates of a recording amplifier block. The output of the amplifiers is applied to the magnetic heads to play-back amplifiers connected to gates of coded signals recording controller. The latter includes coincidence gates and registers as well as OR gates checking the validity of bytes recording.

Title: Resin modified heavy oil to plug expansion gaps in concrete paving - preventing moisture ingress and subsequent erosion
IPC: E01C11/10
Filed: 1981-04-06
Abstract: Gaps or slots between concrete slabs are filled with a mass of plastic or elastic material injected at the base of the gaps between the slabs to flood the gaps below the level of a conventional capping strip. Specifically the filler is injected by holes typically 1-2 cm bore drilled obliquely through the slabs to their lower edges to reach any substrate cavities and to flood the slots or gaps from below.

Title: House with integral solar heating - has one or more collectors accumulating heat in foamed concrete foundations
IPC: F24D11/00
Filed: 1981-04-17
Abstract: The heat store is defined by foundations (1) which are deepened, enlarged and made to be heat insulating by using foamed concrete. The tubes (2,3) for circulating the warmed air are placed on the ground before the foundations are excavated and the material removed from the excavations (4) is placed over the tubes and forms part of the heat accumulator. A single heat insulation layer (6) insulates the top surface of the accumulator and the bottom of the floor slab (7) while the collector has a transparent wall (8), absorbent wall (9) and a support wall.
