Title: Thermostatic valve with time switch control - has expansion element between thermostat and valve, with no mains connection
Inventor: SCHONHARDT PETER
IPC: G05D23/02
Filed: 1980-06-02
Abstract: The thermostatic valve is for temperature-dependant control of a passage medium and time-dependant pre-control of the valve tappet. A mechanical axial expansion element (9) is located between the pressure pin (6) of the thermostat and the valve tappet (3). The axial length of the element can accommodate two or more positions. The movement from an initial position to another and back is by an electric servo drive (24). This in turn is controlled by a programmed electrical time switch. The servo drive motor is actuated by a time switch contact and in turn moves the expansion member via a servo transmission.

Title: Heat pump operating system - defrost on evaporation pressure falling to specified value and continues operation after set period
Inventor: ESCHER SIEGFRIED
IPC: F25D21/00
Filed: 1980-06-16
Abstract: The heat pump operating system periodically stops the heating action and defrosts the evaporator. Defrosting takes place when the evaporation pressure in the latter has fallen to a first specified value, and the heating operation is continued if stoppage has occurred at least twice within a preset time, in order to reach this value. After a lower value of the evaporation pressure has been reached, the evaporator is defrosted again. For the first value of a pressure, corresponding to an evaporation temp. of between -3 and -14 deg.C can be selected. The preset defrosting period may be 30 min.

Title: Spacer for vertebral prosthesis - has oval shaped, concentric, telescopic members rotated into locked position to engage threaded portions
Inventor: KELLER ARNOLD
IPC: A61B17/02
Filed: 1980-06-26
Abstract: The distance piece is for insertion in a vertical prosthesis, and for embedding in cement to form a connection with a section of bone. It consists of two sections (1,2) which slide telescopically. The upper section (1) has a tube (5) forming a skirt with inner threads, and the lower section (2) has an externally threaded stem. Both are oval in shape, permitting the sliding action to give a required overall length. By fixing the lower section and turning the upper section, the threads engage, locking the two sections together. The upper section has flats (17) near the bottom, and the lower section has a hole (16) near its bottom. This enables a tool to be used, having a forked jaw to grip the flats, and a projecting pin to fit in the hole, in order to rotate the upper section. The tool has handles with a tooled locking bar between them.

Title: Horizontal wind-driven rotor - maintains favourable wind wings and rotor axis ratio by using laminated wing structure
Inventor: LICHT ARTUR ING GRAD
IPC: F03D3/06
Filed: 1980-07-14
Abstract: The design of the wind driven rotor is such that the rotation of the drive wings is transmitted by the rotor axis in a 2:1 ratio. This transmission is kept at its most favourable by positioning of the control surface in the direction of the wind force. The wings are pref. of laminated construction, in order to safeguard a regular and uniform run of the rotor, even at various wind forces. In this manner the surfaces of attack of the wings are reduced or increased in size as required. The opening and closing of the laminations takes place via a suitable mechanism by utilising the rotor centrifugal force. Electric power may be also used for adjusting the opening and closing of the laminations.

Title: Safety cage for stone block lifting forks - is locked in safety position by rods projecting downwards and operated by contact with ground
Inventor: BIEDERER FRIEDRICH
IPC: B66C1/24
Filed: 1980-07-24
Abstract: The apparatus for lifting stacks of bricks or stone blocks includes lifting forks. The stack is first placed on the latter, and then a wire cage is lowered to enclose the stack for safety reasons. Attached to each side of the cage is a rod which projects downwards below its bottom. Their ends are bent outwards and spanned by a horizontal rod. When the forks are lifted, this horizontal rod engages a locking device which keeps the cage in its protective position. When the forks are lowered to the ground again, the rods are again pushed upwards by contact with the ground so that the cage can be raised for loading or unloading. The horizontal rod is engaged by a spring-loaded swing arm with a latch member projecting from the bottom.

Patent DE-3107244-A1 (DE)
Title: Internal combustion engine with load control by adjusting the piston stroke
Inventor: DINKELACKER WALTER DIPL PHYS
IPC: F02B75/04
Filed: 1981-02-26
Abstract: An internal combustion engine with spark ignition is described, the load of which is controlled by adjusting the piston stroke, as a result of which the displacement is matched to the required engine power. The friction losses decline with a decreasing piston stroke that is a diminishing load. Furthermore, the charge cycle losses and throttle losses do not increase as the load diminishes, as a result of which the mechanical efficiency is maintained. In this method of load control compression pressure and mean pressure, and hence also the thermodynamic efficiency, remain approximately constant throughout the load range. Similar ratios are thereby created as in the diesel engine with mixture control, the friction losses of which, however, are higher especially at partial load. This new engine concept thereby leads, throughout the partial load range, to a substantially lower fuel consumption than in engines with known charge control. Improved combustion of the mixture with complete charging of the respective capacity also results in a reduction of the pollutant emissions.

Title: Ingot mould having a heat-insulating protective layer
Inventor: TEXTOR MARCUS DR
IPC: B22D17/00
Filed: 1981-05-23
Abstract: The ingot mould has a heat-insulating protective layer of sub-micron metal oxide particles on its working surface. The coating can be carried out by spraying the ingot mould working surface heated to at least 60 DEG  with an aqueous sol of a metal oxide. The use of sub-micron metal oxide particles makes possible the build-up of protective layers having a very small thickness and consequently very low heat conductivity. The coating can moreover be applied and also removed again in a cost-effective manner.
Patent DE-3126570-A1 (DE)
Title: "Timing device"
Inventor: BARRY WILLIAM L
IPC: F01L27/04
Filed: 1981-07-06
Abstract: Air timing mechanism for a high-pressure piston pump with the combination of a piston or a movable wall and an orifice which is set back mechanically during the intake stroke of the pump. In this arrangement, bellows form a variable-volume chamber with at least one mobile wall. An adjustable orifice parallel to a non-return valve is provided in the chamber in order to provide for an adjustable flow output from the chamber and a full flow through the non-return valve into the chamber. The wall is linked to the piston of the piston pump via an arm which is fixed to the piston and is connected to the wall in a slidingly displaceable manner. A switch-over valve directs the pressure medium onto a selectable side of the piston to drive it back and forth. The valve contains a distributing regulator which is linked, via a second arm, to the wall. The pressure medium in the chamber formed by the bellows can work in a closed system, by being forced from the chamber into an external chamber to be reused in the next pump stroke; with an alternative embodiment, the pressure medium can be discharged to the atmosphere.

Title: Process and device for producing plastic bottles
Inventor: HANTICH GERHARD DR
IPC: B29C49/72
Filed: 1981-07-15
Abstract: Plastic bottles with an interior volume which has a low germ count and is preferably sterile are produced by extruding a parison of plastic material, then cutting off a parison piece and inflating said parison piece in a blow mould by means of a blowing mandrel. The inflation bell (neck flash) formed during this process is fused to the unfilled plastic bottle in an airtight manner and, after the plastic bottle is demoulded, is left sealed in an airtight manner on the latter. The airtight fusing of the inflation bells can be carried out by exerting pressure on the still fusible, hot inflation bell wall, but also by, directly after demoulding two plastic bottles, fusing them together with their inflation bells pressed against one another. A device used for carrying out the process has, following the introduction opening of the blow mould, a pinch-off device for the inflation bell. <IMAGE>
Patent DE-3128459-A1 (DE)
Title: Game board with elements which are movable in the horizontal plane
Inventor: SCHUSTER JOACHIM
IPC: A63F9/08
Filed: 1981-07-18
Abstract: The invention relates to a game board, in whose frame there are individual elements. These elements, in this case equilateral triangles, can be transported in that in each case six of these elements, which form an equilateral hexagon, can be rotated about the centre point of the hexagon. Transport of the elements is possible since the equilateral hexagons overlap one another. The rotatability of the hexagons is achieved by simultaneous lowering and turning of the entire hexagon. When pressure is applied to only two opposite triangles of the hexagon, the remaining four triangles are also lowered since their connection to the actuated elements is non-detachable (rigid) and is detachable to the adjacent elements which are not intended to be moved. On completion of the rotation into the desired position, the elements are transported to their position of rest by means of compression springs which are situated below the elements. The game board can be used as a logical and strategic game and as an aid in intelligence tests.
Patent DE-3128461-A1 (DE)
Title: Centring apparatus for palletising machines
Inventor: MNILK REINHOLD
IPC: B65G61/00
Filed: 1981-07-18
Abstract: The invention relates to a centring apparatus for palletising machines. The object is to centre the respective articles to be transferred from the inside. The previous external centring arrangements are in some cases unsuitable because they cannot be used fully satisfactorily, especially in the case of easily deformable reusable boxes. With the centring apparatus according to the present invention, this object is achieved in so far as internal centring is undertaken at the points which are generally subjected to slight deformation. The box centring apparatus consists of centring members coinciding with the inner corner regions of the boxes to be transferred, these members being fixed to a base plate. The base plate itself has, corresponding to the inner contour of the box, recesses at least in some areas of the lateral and longitudinal surfaces of each box, making it possible for additional grippers to be swung at these points into corresponding recesses in the boxes. The use of the centring apparatus makes it superfluous to use a depressor apparatus, which is otherwise customary.
Patent DE-3131478-A1 (DE)
Title: Arrangement for connecting two tool parts rotating about a common axis
Inventor: WOHLHAUPTER GERHARD
IPC: B23B31/107
Filed: 1981-08-08
Abstract: The invention relates to an arrangement of two tool parts rotating about a common axis, in particular for connecting a boring tool (1) to a connecting shank (5). In this device, a pin (3) on one part engages in a recess (4) in the other part, and the pin has at least one tapered transverse bore (7, 8) in which the tapered end of a tapered grub screw (12 or 13) screwed into the other part engages with wedge action in order to clamp the two parts together. In order to permit the transmission of higher torque in such an arrangement and at the same time largely prevent the formation of "fretting corrosion", provision is made according to the invention for the pin (3) to have two tapered transverse bores (7, 8) at an angular distance differing from 180 DEG , and for the tapered end (14, 15) of a tapered grub screw (12 or 13) screwed into the other part to engage in each of these bores. <IMAGE>

Title: Process and apparatus for the continuous separation of polymers from monomers
Inventor: LUDWIG JUERGEN
IPC: C08F6/00
Filed: 1981-09-10
Abstract: The separation of monomers from polymers is carried out by evaporation of monomers with subsequent filtration. Hitherto, the heat necessary for the evaporation of the monomers has been obtained by heating and recycling part of the monomer gas separated off in a filter, this part being fed directly to the polymer/monomer mixture emerging from the reactor. However, this is very complex and is associated with high investment and operating costs. These disadvantages are now avoided according to the invention by carrying out the evaporation of the monomers by warming the piping, i.e. indirectly, at temperatures below the polymerisation temperature. <IMAGE>

Title: Electric clock
IPC: G04B27/00
Filed: 1981-09-26
Abstract: The invention relates to a clock in which both the hour hand alone and the minute and hour hands together can be adjusted via a common setting element which can be displaced for this purpose between two axial positions. The setting element is arranged buried in the battery cover, and in this axial position is accessible for rotary actuation after the battery cover has been removed, e.g. when changing the battery, for the purpose of jointly adjusting the minute and hour hands. In the buried position, the setting element can be gripped manually from behind and displaced axially, and as a result can be rotated from outside the battery cover for the purpose of locking adjustment of the hour hand alone. Care is taken to ensure that there is no problem in effecting axial displacement and reversal of the setting element. <IMAGE>
