Title: Selective contrasting of polymer functional Gps. in amorphous zone - or slightly crosslinked zone, using heavy metal oxide under reducing conditions
Inventor: WEBER GUNTER DR
IPC: G01N1/28
Filed: 1980-07-05
Abstract: Selective contrasting of carbonamide and/or urethane and/or OH gps. in amorphous or weakly crosslinked regions of organic homo- and co-polymers and polymer blends contg. these gps. is effected by allowing a heavy metal oxide (I) to act on the polymer under reducing conditions. (I) is present in a high oxidn. stage and, in its reduced form, forms a stable cpd. with the specified gps. Pref. (I) is Os04 in aq. HCHO soln., the pref. concns., being 0.2-2 wt.% Is04 and 10-50%HCHO. The process is used for selective contrasting in electron microscopic structural investigations. The specified gps. are contrasted without harmful change in the morphology of the polymer. In an example a polyamide-6 sample was kept in a mixt. of 1 pt. 30% aq. HCHO soln. and 1 pt. 1% Os04 soln. for 63 h. 120 000X magnification showed the lamellar fine structure, the contrasting agent being pref. deposited on the carbonamide gps. in the noncrystalline phases and giving a dark image.

Title: Pneumatic timer controller for toaster - uses electric heating coil to control expansion of tube for throttling gap for piston
Inventor: SCHWEER ERHARD ING GRAD
IPC: A47J37/08
Filed: 1980-12-04
Abstract: The timing system for an electric toaster which determines the amount of heat applied to a slice of bread is used with a pneumatic piston (8) inside a cylinder (6). As the piston is pushed upwards by a spring (9), air is forced through a throttling gap (36) which determines the rate of travel of the piston, and therefore the time taken before switching off. The size of this gap is controlled electrically, and is varied by rotating a control knob (46) on the outside. The knob is attached to a potentiometer (44) with wires (40,42,48) connected to a heating coil (38) mains supply so as to control the expansion of a thin sleeve (30) around a rod (34) attached to the casing (32), forming the throttle. Greater expansion of the sleeve decreases the gap (36) between them, reducing the air flow, so as to slow down the piston and increase the time period.

Title: Process for producing rigid plastic profiles with a metal pipe to be introduced by pushing in and plastic profile produced by this process
Inventor: PASCHE HEINZ
IPC: B29C63/18
Filed: 1981-07-27
Abstract: In a process for producing rigid plastic profiles with a metal pipe to be introduced by pushing in, inwardly directed webs supporting the metal pipe, in the chamber of the plastic profile, are shaved off by the pushing in of the metal pipe equipped with cutting edges, to produce a stress-free firm seating. The web shape of the web rows, which are in particular adjacent to one another in a toothed manner, contributes to the centering between the metal pipe and the plastic profile. By this means the metal pipe is arranged in the plastic profile free of play with a firm seat on the surfaces facing it. The pushing in and the holding together are improved by an adhesive which acts as a lubricant during pushing in. <IMAGE>
Patent DE-3138958-A1 (DE)
Title: Brake pressure control unit for a motor vehicle hydraulic or pneumatic brake system
Inventor: BERISCH VOLKER DIPL ING
IPC: B60T8/28
Filed: 1981-09-30
Abstract: In the case of a brake pressure control unit (1) for a motor vehicle hydraulic or pneumatic brake system the brakes on the rear wheels of the vehicle are acted upon by two separate brake circuits. The unit essentially comprises a pressure relief valve (10) and a floating piston pressure reducing valve (110) which is pressure-medium connected to the latter, the first brake circuit (2) being controlled by the pressure relief valve (10) and the second brake circuit (3) by the pressure reducing valve (110). The pressure relief valve comprises a differential piston (70), which is acted upon by a first flexible element (56) in the opening direction of the valve, which element is in turn supported on a clamping piston (50), the clamping piston being acted upon by the master cylinder pressure against the spring force of the first flexible element and the master cylinder pressure acting on the clamping piston being limited by a valve (40, 44) closing as a function of the vehicle deceleration. For the pressure relief valve (10) a second flexible element (94) can be provided, which acts on the differential piston (70) in the closing direction of the pressure relief valve and the spring force of which is less than the spring force of the first flexible element (56). The outlet side of the first brake circuit (2) has a pressure medium connection to a floating piston (118) of the pressure reducing valve (110) in such a way that, owing to the floating piston action of the floating piston (118), the same pressure is also applied to the associated wheel brake cylinder (Rz II) of a rear wheel of the vehicle in the second brake circuit (3) as in the case of the other wheel brake cylinder (Rz I) of the rear axle. In this way the good control characteristics of the first brake circuit (2) can also be transferred to the second brake circuit (3) by simple means. The brake pressure control unit (1) permits emergency operation in the event of failure of a brake circuit. If the second brake circuit (3) fails, the full control function of the pressure relief valve (10) of the first brake circuit (2) is retained. If the first brake circuit (2) fails, the floating piston (118) of the pressure reducing valve (110) shifts into a so-called "locking position", in which the second brake circuit (3) is switched through and unreduced pressure of the master cylinder can be fed to the associated wheel brake cylinder (Rz II). <IMAGE>

Title: Method for stabilising the frequency distributions accruing in a multi-channel analyser
Inventor: BOEHMER RALPH-M DIPL PHYS
IPC: G01D1/00
Filed: 1981-11-12
Abstract: The invention relates to a method for stabilising the frequency distributions, accruing in a multi-channel analyser, with respect to fluctuations which arise in any one of the units of the measurement value generation which precede the multi-channel analyser. The basic object of the invention consists in specifying a method by means of which, in principle, all these fluctuations (compression or stretching of the distribution) can be compensated for by means of an amplifying section connected to the multi-channel analyser. The solution of this object is characterised by the fact that   a) a computer-controlled unit (13, with 12 and 14) is provided which   b) compensates for the fluctuations by means of a factor in the final amplification of the primary measured values in a correction amplifier section (12), by c) recognising a peak displacement of at least one peak (Nm) in the frequency distributions with d) a coarse adjustment by comparing the pulse rate (N'm) corresponding to this peak with the pulse rates (N'm-n, N'n+m; n = 1, 2 ...) of channels located next to the channel of the peak (Nm), and with e) a fine adjustment by comparing the pulse rates (N'm-1, N'm+1) of channels located next to the channel of the peak (Nm).   <IMAGE>

Title: Pipe clamp
Inventor: SCHMIDT HENNING
IPC: H02G13/00
Filed: 1982-01-21
Abstract: Lines which are guided from the roof of a house to the ground, such as antenna lines and especially lightening conductors, are advantageously attached to rain-water drainpipes. The previously known clamps for this purpose are extremely heavy, expensive and difficult to fit. In addition, a separate clamp is required for every type of down-line and for virtually every pipe diameter. The invention specifies a relatively easily constructed clamp which, as a result of this easy construction, can be fitted very simply and can be attached to rain-water drainpipes of different diameter. Nevertheless, this clamp is extremely stable by virtue of its construction and, in addition, has an extremely long life. This is achieved by the attachment means for the down-lines being attached to an angle piece, and the angle piece being inserted with a tongue into pockets in the clamping strip. <IMAGE>
