Abstract: Summary In order to be able, in a simple manner, to erase, by heating, data recorded on bodies with reversible, tempe-rature-variable light extinctions, and then to be able to use the body a new for the recording of data, these bodies consist of at least one polymer material and/or resin matrix material (A) and at least one organic low-molecular substance (B), which is insoluble, at least partially, in the latter and which is contained therein as a dispersed second phase, whereby the pair of materials (A/B) possess variable  light extinctions below a specific temperature (T0) in dependence on a previous heating above To and are so constituted that, upon being heated above a conversion temperature (T2) which lies above T0, and being cooled off subsequently to below T0, yield maximum light extinction; and, upon being heated in the state of maximum light extinction to a temperature (T1) which lies above T0 and below T2, and subsequent cooling off to below T0, yields light extinctions which become smaller with increasing temperature; and, upon being heated to a temperature between T1 and T2 and subsequent cooling off to below T0, yields minimum light extinction.            Such bodies - in film form or in the form of coatings, for example - can be employed as erasable microfilms and other erasable record carriers.

Abstract: RADIAL PISTON FLUID TRANSLATING DEVICE        WITH POWER CONSERVING SCAVENGING MEANS                          Abstract In a pump or fluid motor having a closed chamber in which cylinders orbit and reciprocate, leakage and cooling fluid which accumulates in the chamber is formed into a rotating annular volume by centrifugal effects and exhibits a higher pressure in the region where the cylinders move radially inward and closer together than in the opposite region where the cylinders move outward and further apart.  Power wastage from drag torque, turbulence and heat generation is reduced by scavenging the accumulated fluid from the chamber.  Internal recirculation of the scavenged fluid from the high pressure portion of the annular rotating volume back to the low pressure portion is avoided by communicating the drain passages with only a limited relatively high pressure sector of the rotating volume of fluid.

Abstract: ABSTRACT OF THE DISCLOSURE     In a direct ignition gas burner control system wherein two valves are connected fluidically in series with the burner, a make-before-break thermostatically actuated switch is effective, when a set of "cold" con-tacts are made, to energize an electrical resistance igniter and to open a first of the two valves which opening enables a pressure actuated switch to close its contacts.  When the igniter is above a temperature sufficient to ignite gas, the thermostatically actuated switch makes a set of "hot" contacts while its "cold" contacts are still made.  In this intermediate contact position, a second of the two valves is opened, allowing gas to flow to the burner.  Continued energizing of the igniter causes the thermostatically actuated switch to break its "cold" contacts, effecting de-energizing of the igniter.  When the "cold" contacts are open, the pressure actuated switch provides a hold-in circuit for the valves.  The transitory intermediate contact position of the thermo-statically actuated switch is of sufficient time duration so that, in the event the pressure switch contacts momentarily open due to a drop in pressure when the second valve opens, the valves will remain open.

Abstract: LONG-LIFE MILLED TOOTH CUTTING STRUCTURE Abstract of the Disclosure One or more holes are drilled into the crest of the tooth-shaped cutting structure of a milled steel tooth rotary rock bit.  Tungsten carbide rods are positioned in the holes and hardfacing is applied to the tooth.  The hardfacing is applied across the top of the tooth crest and acts to hold the tungsten carbide rods in place.  The rods are inserted in holes parallel and close to one flank of the tooth so that the entire length of the carbide rods can be attached to the hardfacing by burning the hardfacing through to the carbide rods.  Wear on the tooth will proceed along the side of the tooth not reinforced with the carbide rods and a self-sharpen-ing effect is enhanced by the strength of the carbide rods. The carbide rods and holes therefore can be relatively inexpensive, since close tolerance finishing is not required.

A  process  is described for improving the activity of supported silver catalysts which have already been used, in which the used catalyst is first washed with an inert liquid containing ammonia and/or aliphatic amines and 1 to 1,000 parts, per 1 million parts of catalyst, of cesium, rubidium or a mixture thereof is then deposited on the washed catalyst.     The deposition is generally effected with the aid of an impregnating solution containing the cesium and/or rubidium compounds in a suitable quantity.     This process makes it possible to improve considerably the activity of supported silver catalysts which have already been in use for the oxidation of ethylene by means of oxygen or air.

Abstract: ABSTRACT            "Fireguard for Hose Assembly"     This disclosure relates to a fireguard for pro-tecting a hose or an assembly of a hose and fittings. The fireguard includes a layer or tube of a silicone compound which is positioned around the hose, and a metal shroud or sleeve which encloses the layer of silicone compound.  The silicone compound and the shroud protect the hose at normal temperatures and for a short length of time at a high temperature. In the event the high temperature persists for a length of time, the silicone compound decomposes to a layer of silica ash, which is held in place between the shroud and the hose, and the ash forms an excel-lent heat insulation for an extended time.  The shroud is preferably flexible so that the hose may be bent, and the fireguard preferably also includes another layer of the silicone compound and a collar around each hose fitting.
