Title: Preventing incrustations on surfaces in aq. systems - using chemical to form thin film on contacting surface
Inventor: SCHOLL GERHARDT ING GRAD
IPC: B01D53/48
Filed: 1977-03-28
Abstract: A process to prevent the formation of incrustations on surfaces brought into contact with aq. solns. contg. substances having a tendency to separate in the crystalline state, esp. in installations for desulphurising gas fumes using solns. contg. alkali or alkaline earth metal ions as absorbing agents or in measuring devices immersed in such solns. comprises adding to the aq. solns. a chemical substance giving rise to the formation of a thin protective film on the contacting surfaces. The process is esp. applied to appts. for physical and chemical measurements in aq. medium. The process avoids blockages and also erroneous measurements.

Title: Grinding machine for scissors blade - with rotary motion about longitudinal axis superimposed on longitudinal motion of blade engaging dished grinding disc
IPC: B24B3/52
Filed: 1977-04-07
Abstract: A scissors blade is ground by means of a dished grinding disc which engages on a mounting. After positioning in the dished disc, the blade is moved in a longitudinal traction plane which is set at an angle gamma greater than 90 deg. to the dish grinding disc axis. A rotary motion about its longitudinal axis is superimposed on the longitudinal traction motion and the blade carries out a helical motion. On termination of the longitudinal motion, the scissors blade is swivelled away on an arc. A support carries the workpiece via a support plate with a grinding base and a tensioning device. The support can be moved along a slide table.

Title: Circuit breaker hydraulic drive piston position indicator - has plunger with riders moving in piston between indicator switch on and off positions and fault position
Inventor: PALM JOACHIM ING GRAD
IPC: F15B15/20
Filed: 1977-05-09
Abstract: The position indicator, for indicating the position of a hydraulic drive's piston, as used for circuit breakers, etc., has a plunger (11) moving freely in the piston (3) and acting on an indicator switch. The plunger is forced to move between on and off positions depending on the position of the piston. Outside these on and off positions, the plunger is moved by a spring into a 'fault' position. The plunger has riders (14, 15) that interact with stops (16) on the piston.

Title: Filament warp yarn winding - has unsized yarns on either side of warps along beam
Inventor: GAENZLER ROMAN
IPC: D03D15/00
Filed: 1977-08-19
Abstract: In forming the warps for winding on to a warping beam, using smooth, untwisted and sized filament yarns, the edges of the band of warps are composed of yarns which are unsized. The warp arrangement allows the warps to be wound on to a beam provided with gaps at the eneds, to allow for temperature variations in operation, without allowing the warps for weaving to be caught and damaged. The edges of the line-up of warps are composed of one to three yarns on either side, using texturised and particularly false-twisted texturised yarns, or yarns which are highly twisted. The yarns for the edges of the warps on the beam are of the same gauge or higher than the titre of the yarns forming the warps for weaving.
Patent DE-2737428-A1 (DE)
Title: Book binding open signature stitching - starts with supply of spine-down open signatures on conveyor carriers to stitching device in lateral alignment
Inventor: RATHERT HORST ING GRAD
IPC: B42B2/06
Filed: 1977-08-19
Abstract: The signature supply order corresponds to the book page sequence, and the lateral alignment is provided by a guide edge. The open signatures are stitched by rotary needles with suitable threads. The thread coils penetrate the signatures from below, due to the needles oblique position, the pitch of the thread coils, and in dependence on the feed velocity. The threads leave the signature(s) in a spacing corresponding to the width of the stitches. Then the threads, which have passed through the signature(s) from a zig-zag connection and are slipped through the individual signatures at several points. The block of signatures is then lowered by the carrier, rectangularly aligned, and its spine glued.

Patent DE-2827686-A1 (DE)
Title: Scissors with inclined pivot bolt - has blades held in contact at cutting point without grinding to special shape
IPC: B26B13/28
Filed: 1978-06-23
Abstract: The pivot bolt of a pair of scissors or shears is arranged so that its axis is inclined to a line perpendicular to the plane of the scissor blades. The bolt axis is inclined in both the longitudinal and the transverse directions. This inclination of the bolt axis ensures that the blades are always pressed together at the cutting point and only at this point. The mating surfaces of the blades are ground flat and do not need to be ground with a special curvature as is the case with conventional scissors.

Title: PTFE-reinforced fluoro-polymer ion-exchange membrane - for cells producing chlorine and highly conc. alkali hydroxide
Inventor: BABINSKY ANDREW DANIEL
IPC: C08J5/22
Filed: 1978-10-09
Abstract: Fabric-reinforced ion exchange membrane is prepd. by first hearing a fluoro-polymer material contg. pendant side chains contg. sulphonyl gps. linked to C atoms, which themselves are linked to at least one F atom, to a temp producing sufficient flow of the polymer by melting to enable it to laminate with an open-meshed reinforcing fabric. The reinforcing fabric is then applied to the surface of the heated polymer with sufficient pressure to ensure that the polymer flows at least partially through the fabric and forms a laminate. The surface of the fluoro-polymer is treated with prim. and/or sec. amine, so that a major portion of the sulphonyl gps. on the surface are converted into the -SO2N-form, to a depth of >=10 (esp. 38-50) mu m. The aminated surface is continuous, does not include any micro-cracks and coasts the reinforcing fabric. Used for the prodn. of Cl2 and alkali metal hdyroxides, partic. in high concns. The membrane does not break and is satisfactory in cells operating under high current yield and low voltage.
Patent DE-2846516-A1 (DE)
Title: Reaction engine for vehicles - has opposed pistons in common cylinder with unequal resistances to produce net forward force
IPC: F02B71/00
Filed: 1978-10-25
Abstract: The engine has opposed pistons moving in opposite directions in a common cylinder. The combustion space is formed between them. One outer end of the cylinder is open to atmosphere so that there is no resistance to the movement of the piston on this side. The other end of the cylinder is closed so that the other piston compresses air on the side away from the combustion chamber and thus experiences a resistance. This results in unequal forces on the two pistons. As they are linked together there is a net force on the unit which gives a reaction force on the cylinder which propels the vehicle forward.
Patent DE-2847477-A1 (DE)
Title: Rotary driving or driven machine - has paired pistons in toroidal cylinder with one pair rotating steadily and cranks in drive-line to other
Inventor: REISEN RICHARD

Abstract: The rotary driving or driven machine has pistons in diametrically opposed pairs, connected to coaxial shafts and geared together. These rotate at relatively varying speeds to vary the working chamber vols. One of these pairs secured to the cylinder, rotates at steady speed driven from the (hollow) main shaft by planet gearwheels whose spindles run through bearings in the pistons. The other pair of pistons is fixed to a sleeve around the shaft with connecting rods to opposed cranks on the free ends of those spindles.

Title: Animal carcass skinning machine - with skinning flap cutter in revolving skin grip and skinning blade
Inventor: LEINING LYNDON R
IPC: A22B5/16
Filed: 1979-05-10
Abstract: A machine for skinning animal caracasses, specially pig carcasses, includes a rotatable vertical cylindrical drum, and a skinning blade next to it for the trunk portion of the carcass. The drum has a device to form and grip a flap of the skin at the start of the operation. A blade on the drum produces a longitudinal cut, when the carcass in urged against it, and the skinning blade progressively separates the skin from the carcass. This leaves a min. ambient of fat on the skin, requiring no other operation before its conversion to gelatin. The new method saves scalding and singing.
