Patent DE-2105302-A1 (DE)
Title: Concrete solidification acceleration
IPC: B29D11/00
Filed: 1971-02-05
Abstract: Acceleration of setting of concrete is effected by the application of external heating devices which cover its surface and insulate it from its surrounding, maintaining a temp. above ambient at its surface. The application of heat is accompanied by the application of water which is passed through the heating element to wet the surface of the concrete being dried. The process is carried out preferably by a blanket type heating element having an outer impervious and heat insulating covering, an inner sponge lining and a system of water feeding channels connecting with the lining. The advantage of applying water at the same time as heating is that moisture helps the setting reaction of concrete and prevents the harmful effects of dry heat, which would result without it.

Title: Rope making machine - has guides and reversal facility for material being drawn from reels into assembly point
IPC: D07B1/22
Filed: 1971-06-11
Abstract: Rope making machine has an assembly point and several reel holders with a reversal facility for the material, coaxial and parallel to the centreshaft, with guides to carry the material from the reels. This is directed from the reels in gps., through the guides, with reversal and without selftwist, to the assembly point. Machine is supported at the front end astride a pair of rollers and similarly at the centre section on rollers. At the rear a frame contains a bearing for the centreshaft. Machine is driven along the axis with parallel shafts supporting reels and guides. There are two reels, with bearings between, with a total of eight reels in the rear section which are located on vertical radii. The eight reels in the front section are located horizontally. This allows the material from to pass unhindered through the guides in section, having bundles of four, top and bottom. Guides are held on the shafts, which are driven by gears in the middle section and reverse by intermeshing with gears on the centreshaft. Material is drawn from the reel by nearby rollers and guides which lift the material into eyelets through the bearing brackets out of the way of other reels, and through to the front of the machine. In the rope forming and assembly unit are guide tubes and gears to assemble the supply of material from the reels, and form the rope. The formation may be round or square, depending on the proportion of reversal twist given to the material.

Title: Coolant temperature/oil pressure-controlled vehicle engine protection - temperature and pressure-sensitive switches parallel in main relay circuit
Inventor: WISCHERMANN JOSEF
IPC: F01M1/22
Filed: 1973-06-26
Abstract: The oil pressure sensor and the coolant temperature sensor are electrical switches, each of which controls the main relay whose actuation will switch the engine off. The pressure sensor responds to the oil pressure dropping below a pre-determined valve, the temperature sensor responds to the coolant temperature exceeding a pre-determined valve. In the case of a petrol engine the relay contact is preferably in the ignition circuit. The sensor switches preferably close near the un-safe condition and the main relay is energised to break its contact. The relay contact may, alternatively, control a solenoid valve in the fuel supply line.
Patent DE-2340723-A1 (DE)
Title: Firmly attached pan handle with spring - has metal slave abutment for latter allowing larger reaction forces to be absorbed
Inventor: BAUMGARTEN RUDOLF
IPC: A47J45/07
Filed: 1973-08-11
Abstract: The plastics handle is fastened by a support welded on to the pan wall and has a recess to house the spring which locks the handle onto the handle support. The point of attachment is covered by the metal sleeve and the spring lies on the inside of the sleeve. As the handle is positioned, the nose of the web of the stirrup-shaped spring slides onto the wedge part of the support and then onto the upper edge of the support, whereupon the spring exerts pressure on the handle forcing it against the pan wall. The reaction forces arising from the spring are taken up by the sleeve and not by the plastics part of the handle as before. Thus a stronger spring can be used without damaging the handle body.

Title: Resistance welding steel bars for concrete reinforcement - using bulges or projections on the steel to give strong welds
Inventor: KOSOLAPOW IOSIF I
IPC: B23K11/14
Filed: 1973-12-14
Abstract: Two steel elements, one of which is a bar, are joined into a grid or frame, by providing >=1 of the elements with a bulge or a projection and making the electrical resistance weld between the bulge on one element and the flat surface or bulge on the other element. The grid or frame can be made of longitudinal girders, e.g. with an L-cross-section using round bars as the cross-members; in this case, the ends of the round bars are pref. provided with bulges where the weld is made. The flat surface of a rectangular bar may also be provided with a continuous projection. The purpose of the bulges is to localise the weld into one spot so that adequate penetration is obtd. i.e. standard practice in resistance spot welding. The joining oc concrete reinforcing grids using arc welding produces joints of good quality but the process is slow and expensive, the present invention permits the use of resistance welding which can easily be mechanised for the automatic prodn. of grids.
Patent DE-2362520-A1 (DE)
Title: Continuous electronic control of resistance welding processes - for spot, projection and seam welding using seismic transmitter
Inventor: KRAUSE HANS-JOACHIM DR ING
IPC: B23K11/24
Filed: 1973-12-15
Abstract: The positive and negative absolute values of the speed-, acceleration-, or path- amplitudes of an electrode are measured during the welding current flow, i.e. during the pulse, and are processed and compared with prescribed standard values. The measurements can be integrated and displayed or, with the aid of a circuit, converted into positive and negative pulses which are then integrated and displayed. A tolerance unit can be linked to the display unit so a signal is given when prescribed limits are exceeded so the welding machine can be adjusted before the next operation; alternatively, the measurements can fed to a comparator supplied with standard values and the difference used for phase control. Consistent welds with optimum quality can be obtd. in spot, projection or seam welding.

Title: Articulated joint for fold up camp beds etc. - has gearing in swivel joints allowing automatic extension of all frames in one hand movement
Inventor: SCHNUETTGEN ALFRED
IPC: A47C17/68
Filed: 1974-02-09
Abstract: The articulated joint comprises essentially three parts which extend to form the leg and bed frames and swivel round to fold flat in the non-use position. Gear drive members are mounted on two of these parts wherein the gear drive member on the part which is adapted to rotate 180 deg. round a first part i.e. on the back rest frame has a larger diameter and more teeth than the gearing on the third joint member i.e. on the bed leg which is locked in the position of use by the second joint member i.e. back rest frame which is provided with the gearing. These two gearing mechanisms only mesh in the first swivel zone of the second joint member and as the second joint member is moved back from its second to its first swivel range the two gearing mechanisms are automatically brought into engagement once more by a further mechanism. Although the bed can be unfolded automatically in one step the back rest can still be adjusted individually.
