Title: Draught excluder for fitting to lower edge of door - has internal mechanism to raise it clear of floor as door is opened
Inventor: CRONENBERG DIETER JULIUS
IPC: E06B7/215
Filed: 1991-11-28
Abstract: A draught excluder for fitting to the lower edge of a door consists of a housing (10) of inverted U cross-section which is fastened to the door (1) by means of screws (15). The housing (10) forms a guide for a second U shaped section (21) which has a specially shaped groove in its undersurface. This groove receives the upper edge of the flexible sealing strip (22). The assembly of the inner section (21) and sealing strip (22) is held clear of the floor when the door is open by means of a leaf spring. This leaf spring passes under transverse pins fixed to the inner section. When the door is closed, one end of the leaf spring is pushed inwards by means of a horizontal slider actuated by contact with the doorpost. The end pressure on the spring causes it to bulge downwards and press the sealing strip (22) against the ground. USE/ADVANTAGE - Draught excluder which is held clear of the floor whilst the door is being swung to open or closed position.

Title: Surface corrugation test - uses light at a flat angle to give projected image on a screen for corrugation peaks and valleys to be measured
Inventor: BERG ROBERT VAN DEN DR
IPC: G01B11/30
Filed: 1992-03-10
Abstract: To determine the deg. of corrugation at a surface, the surface is illuminated (LQ) at a flat angle (Wl) and the reflected light is shown on a screen (LW) as an image (SP). The corrugation is measured by the repeated peaks and valleys on the projected image. A unit to form shadows can be laid and/or moved across the surface scrutiny, as a shadow screen. The corrugation of the projected image is compared with an image of a known corrugation to measure the gaps between the corrugated peaks and valleys to locate and mark the peaks on the surface. USE/ADVANTAGE - The method is used for quality control of worked surfaces, such as pretensed or hardened glass panes, and other surfaces which have been machined and the like, which would affect the transparency or reflection characteristics, such as in building cladding materials. It is also used to monitor the quality of thin deposited layers for solar cells. The technique gives a rapid, simple and accurate test of the corrugation at a surface.

Title: Method for preparing spark-forming pulses and ignition system for carrying out the method
Inventor: VICHNIAK ZAKHAR
IPC: F02P3/09
Filed: 1993-04-28
Abstract: The new means of preparing spark-forming pulses is intended to extend the application area of known capacitor ignition systems into the low engine speed range and as a result to permit them to be used also on passenger cars; this is to be combined with a reduction in production costs by reducing the size of the cooling elements and the use of mini ferrite ignition transformers. For this purpose, both the engine speed and the charging of ignition energy accumulators are to be monitored and in each case a packet of the steeply rising brief spark-voltage pulses is prepared from the start up to a prescribed engine speed value at each prescribed ignition time, each subsequent pulse being produced at the time of the next complete recharging of the ignition energy accumulator while in the engine speed range which lies above the prescribed engine speed value individual pulses instead of pulse packets are prepared and the charge time constant is increased. A new component of the ignition system is an engine-speed discriminator (8) for monitoring the engine speed; the charge device (3) has a power control input (3.1) for switching over the charge time constant and an output (3.2) which indicates readiness for operation as a charge-termination indicator; the control device (4) has packet and individual-spark modes of operation, an operating selection input (4.2) for switching over the mode of operation and a gating input (4.3) for permitting internal packet pulses to be formed. Further (conventional) circuit components: synchronous clock transmitter (1), pulse shaper (2), storage capacitor (5), ignition (ferrite) transformer (6), ... Original abstract incomplete. <IMAGE>

Abstract: The invention relates to a process and the associated apparatus for the utilisation (valorisation) of mixtures of combustible organic substances and clay or carboniferous clay by recovery of a tar-free CO-containing and H2-containing combustion gas and coarse ceramic products (building ceramics) or components. For this purpose, the mixtures shaped into green bodies are subjected in a chamber (1) to heat treatment in a steam-containing reducing atmosphere by direct contact with a steam-containing circulating gas which is circulated and heated before this contact in a circulating gas heater (15, 23). In this heat treatment, there takes place at temperatures of up to 200@C the drying of the green bodies, at temperatures of 200-700@C the pyrolysis of the organic substance and a ceramic consolidation of the green bodies, at temperatures of 700-900@C the gasification of the carbon formed during pyrolysis, a further ceramic consolidation of the green bodies and a leach-proof binding-in of environmentally significant heavy metals which can be completed at temperatures above 900@C. <IMAGE>

Abstract: The use of copolymers (I) contg. 0.1-99.9 wt% 4-vinylphthalic anhydride, 4-vinyl-phthalic acid and/or dialkyl 4-vinylphthalate ester (II) and 99.9-0.1 wt% vinyl and/or diene comonomer(s) (III) as components of polymer alloys is claimed. ADVANTAGE - (I) have a desirable combination of properties as components of polymer alloys, e.g. markedly better heat distortion temp. than corresp. styrene homopolymers, together with the possibility of reactive phase coupling (via acid or anhydride gps.) (I) are therefore useful as compatibilisers in polymer alloys and for the prodn. of polymeric networks; copolymers contg. more than 50 wt% 4-vinylphthalic acid units are soluble in aq. alkali and are therefore also useful for the prodn. of resist materials. In an example, 4-Vinylphthalic acid was prepd. by bromination of phthalic acid with bromine in aq. NaOH soln., followed by reaction with ethylene for 16 hrs. at 100 deg. C and 40 bar in the presence of Et3N, Pd(OAc)2, tri-o-tolyl-phosphine and DMF, pptn. with CaCl2, soln. and acidifcation. The acid obtd. was sublimed at 90 deg. C and 0.03 mbar to give 4-vinylphthalic anhydride (VPA). A copolymer contg. 10.5 wt% VPA and 89.5 wt% styrene (by FT-IR analysis) was prepd. by radical polymerisation in acetonitrile with AIBN as initiator, followed by re-pptn. from THF/methanol. The prod. had Mn, 5700; Tg, 91 deg. C (cf. 4900, 74 deg. C for 100% styrene homopolymer); a copolymer of 67.4 wt% VPA and 32.6 wt% styrene was soluble in aq. NaOH soln., with Mn = 2200 and Tg = 160 deg. C.
