Abstract: Phenolic resin particles which are useful as friction particles for use in friction elements, such as brake linings, clutch facings or other braking devices, are produced by dispersing a liquid, heat curable phenolic resin in a paraffinic oil having a viscosity of at least 216 centistokes at 37.7°C (1,000 SUS at 100°F.) at a temperature of 100 to 175°C to cure the resin. Preferred friction particles are prepared from phenolic resins containing benzylic ether linkages by curing in the hot paraffinic oil or by other heating methods. Friction elements containing such particles and a friction binder are also described.

Abstract: A rotary collating machine, and method of collating, utilises the principle of peeling individual sheets of paper, card or like material from the bottom of a number of stacks of sheets (23) arranged around a flat segmented table (22a to 22f) which supports the stacks by air pressure issuing through holes (30). Perforated suction wheels (32) equispaced around the table between the segments draw down a corner of each bottom sheet as the wheels rotate beneath the stacks. The withdrawn sheets are held by suction on the wheels (32), guided down through slots between the table segments (22a to 22f), inverted as they are peeled away, and deposited in catching trays (36) beneath the table to build up collated sets which can be removed by a stripper bar (38).

Abstract: A silicon chip (38) mounted on a glass base (34) has two cavities (44, 46) formed therein, each defining a diaphragm (48, 50). Ion implanted resistors (52) are formed in each diaphragm and are connected to a Wheatstone bridge circuit. One of the chip cavities (46) is evacuated to a vacuum reference pressure so that barometric pressure is sensed by the corresponding diaphragm (50) when the atmospheric pressure is applied to the top of the chip (38). The other cavity (44) is connected to a pressure source, such as manifold vacuum of an internal combustion engine so that the corresponding diaphragm (48) will measure the differential pressure between the manifold and atmosphere. The output signals of the bridge circuits are combined in such a way as to give a sensor output proportional to the absolute manifold pressure.

Abstract: A pulsed solid state system having solid state elements (80) responsive to drive pulses for generating RF signal pulses includes a timing circuit (20,22,24) generating signals which are applied to a pulse forming circuit (33) to provide preheat pulses and immediately subsequent thereto the drive pulses which are applied to the solid state elements (80) so as to reduce chirp and level variations of the generated RF signal pulses. The preheat and drive pulses are formed by transistors (70,74) which are rendered conductive when their current return paths are established through resistors (34,44) whose values determine the levels of the preheat and drive pulses. The duration of the preheat pulses may be made responsive to ambient temperature by using a negative-temperature- coefficient thermistor as the time determining element of the timing circuit (20,22,24) and the level of the preheat pulses may be made responsive to ambient temperature by using positive-temperature .coefficient silicon thermistors in the above mentioned current return path.

Abstract: An improved process for preparing N-phosphonomethylglycine is described. In this process, a glycine substituted on the nitrogen by a radical which can be removed by hydrogenolysis is first reacted with formaldehyde and phosphorous acid in aqueous acidic reaction medium to give a corresponding N-substituted N-phosphonomethylglycine, from which the substituent originally present on the nitrogen is then removed by hydrogenolysis. N-Phosphonomethylglycine is a herbicidal active substance having a broad spectrum of action, which has only a few or no residual effects whatsoever.

Abstract: There is proposed a method for producing a multi-layer building element comprising a relatively thick slab-like part (4) having a first density, and a relatively thin slab-like part (1, 6) having a second density arraged on one or both sides of the relatively thick slab-like part (4) having said first density, the second density being higher than the first density. The slabs comprise a form-stable, but still uncured aerated concrete cut from one or more porous blocks of uncured aerated concrete and are lifted with the aid of suction and lifting means and moved to a support means (2), where they are stacked completely or partially one upon the other in a sequence corresponding to the desired structure of the building element to be formed. The slab layers are bonded together with a mass (3, 10) containing a hydraulic binder arranged in layers between the superposed slabs. Subsequent to forming a sandwich building element in this way, the element is charged to an autoclave and steam-cured therein.

Abstract: An aluminium bearing beta copper alloy that on heating to a first temperature shows a transition from an (alpha + beta)-region, an (alpha + beta + gamma)-region or a (beta + gamma)-region to a beta-region. 
     Its average grain size is less than 200 pm and it contains aluminium bearing precipitates, e.g. Co-Al-precipitates, the average size of which is less than 10 µm and which are insoluble in the alloy below a second temperature that is higher than said first temperature. 
     The fine grain structure guarantees an excellent mechanical and thermomechanical behaviour of the alloy, while the aluminium bearing precipitates guarantee that this structure and hence the advantageous behaviour of the alloy is maintained as long as the alloy is not heated to said second temperature.

Abstract: Laying optical waveguides into sinuous grooves of a support filament while holding the grooves in the same position as the filament passes through a waveguide laying station by causing the filament to twist in oscillatory fashion during passage through the station. The grooves are held in the same positions by positionally fixed guide projections located in the grooves. By this laying method, the waveguides themselves are not oscillated around the support filament as they are fed into the laying station. Also, guide elements to feed the waveguides into the grooves extend downstream to a wrapping station whereby tape wrapped around the support filament also is wrapped around the guide elements. The waveguides exit from the guide elements after the tape has been wrapped.

Abstract: Positive lens surfaces 25 on one side of a lens plate 22 converge light rays towards respective light-transmitting interstices 23 in an otherwise opaque or light-absorbing baffle 24 disposed on the opposite side of the plate 22. This arrangement serves to reduce the visibility of the internal components of the lamp when viewed from the front, and at the same time minimises the occurrence of "ghost" signals produced by externally incident light. In order to reduce the spread of the light rays emerging from the opposite side of the baffle 24, each interstice 23 is associated with a formation 26 on the lens plate 22 which is specifically designed as a negative lens surface.
