Title: Delta modulation in inertial navigation system - using two measuring chains with sensitivity integrators by timing pulses
Inventor: HOFMANN FRITZ DIPL ING
IPC: H03M3/02
Filed: 1976-01-23
Abstract: Zero point and resolution errors as well as disturbances in a delta modulation measuring unit of an inertial navigation system are reduced by switching the sensitivity of the integrator input and by including a second measuring unit which operates during a reversal of measurement direction. A detector coupled to reversing table and motor is controlled from a logic circuit. Its measured value is integrated in a measuring chain for application to a navigation computer. During reversal operation a second detector supplies a measured value to a second measuring chain integrator and the respective output is routed via a switch to the computer. Sensitivity is changed by switches in resistive divider circuits. A programming unit and clock generator with synchronisation units ensure correct timing of operations.

Title: Asbestos seals or packing materials - treated with alkali to remove chloride cpds. causing corrosion of metals or glass in service
Inventor: HAACK HANS
IPC: C03C25/66
Filed: 1976-10-28
Abstract: Purified, noncorrosive asbestos materials are obtd. by an alkali treatment which substantially reduces their halide content, pref. by more than half the initial content. The initial asbestos or asbestos material is pref. exposed to alkali, and then washed with water and dried for mfg. seals, sheet, packing, cords, etC. The alkali is pref. a 1-5% soln. of K2CO3 and/or Na2CO3, used for 1/4-24 hrs at room temp., followed by washing with water at room temp. until the wash water is only feebly alkaline. In mfg. seals etc. or insulation, the asbestos can corrode components such as radiator valves; showcase window glass; glass observation windows on high temp. appts. The invention prevents such contact corrosion. An asbestos cord intended for a seal contained 0.55% Cl as chlorides. The cord was heated 72 hrs. at 500 degrees C so volatile chlorides, e.g. of Fe or Mg, evaporated; the cord then contained 0.038% Cl. The cord was next immersed for 4 hrs. at 20 degrees C in a 5% soln. of K2CO3. After drying, the cord contained 0.028% Cl, and the latter content was unchanged after 72 hrs. heating at 500 degrees C., i.e. all the volatile chloride had been removed and would therefore not cause corrosion when the cord was used in service.

Title: Recovery of polyvinyl chloride from tetra:hydro-furan - by addn. water with surfactant to prevent deposit
Inventor: DEUSCHEL WALTER DIPL CHEM DR
IPC: B01D3/14
Filed: 1977-01-14
Abstract: The parent patent refers to a method of separating PVC from soln. in THF, in which the water content is adjusted to 10-50 wt. % before distn. In this addn. 0.1-3.0%, wrt. to the water, of a surfactant is also added before distn. The original method effected practically complete recovery of THF leaving a PVC residue which was easily removable from the distn. vessel and easy to filter. Because of the complete separation of tetrahydrofuran the residue was neither noxious nor polluting. However, the method caused a deposit to form on the wall of the distn. vessel which has to be removed mechanically. The addn. of a surfactant eliminates this defect.

Title: Hot pressing chipboards in continuous sequence - by moving loaded cauls stacked in trays upwards in stack press
Inventor: BRUESSEL RICHARD
IPC: B27N3/20
Filed: 1977-01-21
Abstract: Building boards are made from binder and wood chips, wood wool, or other fibres, these materials are continuously spread into loads on cauls and these are stacked in a moulding tray and hot pressed. Moulding trays are moved singly from below into a heated stack press, stacked, pressed upwards at 50% of the working pressure and removed again. The sequence is as follows: (a) at 50% working pressure one fresh moulding tray is carried down and placed on the lower press ram; (b) the ram moves it up to the bottom of the previous tray, overpresses the pressure of the top press system until top stop members meet cams on the second highest tray, builds up the necessary pressure and holds it until the expansion of the load has dropped; (c) the top tray is suspended by a gripping device in the ram of the top press system; (d) pressure is released at the top press system, at the same time the top tray is lifted to its ejection level by the press ram; (e) the unloading carriage moves up, releases and carries out the top tray; (f) the top press system and ram move to the now top tray, overpress the bottom press system until the second lowest tray rests at the bottom stop members; (g) the top stop members are moved out; (h) the bottom press system overpresses the top press system; (i) the lower stop members move out; (j) the bottom press system overpresses the top one until the cams on the top tray are above the top stop members; (k) the top stop members move in and the cam on the second highest tray moves on to it; (1) the holder of the bottom tray is thereby moved above the level of the bottom stop members and the latter are moved in; (m) the top press system overpresses the bottom one until the cam of the bottom tray rests at the bottom stop members; and (n) the bottom press system moves out at the loading level. Process only requires half the number of trays previously used, no cover plates are required, no grips on the pressure-reducing press, low pressure on the trays, simplified process and hence cheaper prod. Process is suitable for surfacing chipboard with films, paper etc. or to bond to plywood.
