Filed: 1972-12-12
Abstract: 1414174 Block copolymers STAMICARBON BV 12 Dec 1972 [15 Dec 1971] 57225/72 Heading C3P Elastomeric block copolymers of the general formula A-B-C, at least blocks A and B being linked by styrene units in which A is a non- elastomeric block derived from α-methylstyrene units and having a number average M.Wt. of 2000 to 100,000, B is an elastomeric block with a number average M.Wt. of 15,000 to 250,000, and C is a non-elastomeric block with a number average M.Wt. of 2000 to 100,000, and wherein A and C are identical if a linkage agent is used, are prepared by forming a polymer block from α-methyl-styrene at below 0‹ C. with the aid of a monofunctional anionic initiator, reacting the block so formed at below 0‹ C. with 1-100 molar proportion of styrene based on the initiator, forming an elastomeric block at above 0‹ C. and then forming the A-B-C copolymers by adding a linkage agent or by forming a further non-elastomeric block. In examples sec.-butyl lithium is used an initiator and 1,3-butadiene used to form the elastomer block. Amyl acetate, divinyl benzene and methylenediphenylene diisocyanate are used as linkage agents to give as product an α - methyl styrene - styrene - butadienestyrene-α-methyl styrene block copolymer.

Title: Charge storage diode circuits for delaying analogue signals
Inventor: KRAUSE GERHARD
IPC: G11C19/18
Filed: 1968-09-19
Abstract: 1,244,362. Analogue signal delay and storage circuits. FERNSEH G.m.b.H. 19 Sept., 1968 [18 Nov., 1967], No. 57230/70. Divided out of 1,244,361. Heading H3U. An analogue signal delay circuit comprises a series of diodes 715-719, charge storage diodes 721-724 connected to the junctions of these diodes and means for biasing the diodes cyclically so that a sample of the analogue signal stored in the first storage diode is passed along the storage diodes. As shown, when the clock pulse U 8  is negative a sample of the input signal at 714 is stored in 721. When the clock pulse becomes positive 721 is discharged into 722. Thus the sample is passed along. Diodes 722 and 724 may alternatively be connected to clock pulses of opposite phase (Fig. 2, not shown) and the circuit may be preceded by a gate opened only for a short period during the clock pulse (Fig. 3, not shown). The clock pulses may be supplied by a changeover switch (Figs. 4 and 5, not shown). By transferring the samples one at a time in reverse order instead of in groups of alternate stages a greater delay is obtainable. The control pulses may be obtained from a shift register (Figs. 9-11, not shown).

An electrometer comprises two U-shaped filament electrodes arranged in horizontal parallel planes. In the example shown a thin U filament 6 (e.g. 2 to 10 microns in thickness) bends towards a rigid (e.g. stiff wire) U filament 3 when a voltage is applied between tubular metal casing 1 and filament 3. The movement of filament 6 is observed through a hole in a diaphragm or disc 8 with reference to a scale on a magnifying lens 9 and the viewing may be perpendicular via deflecting prism 10 and against a backgound of illumination at 12 through a perforated or transparent disc 2. This disc 2 which supports the rigid filament 3 is of high grade insulating material such as amber, quartz or synthetic material. The movable filament 6 supported on an angle bracket screwed into casing 1 preferably consists of quartz with a sputtered metal layer but may be a platinum wire. The filament 3 has longer limbs and a larger bend than filament 6 so that if an. excess voltage is applied the filament 6 passes through and does not touch the filament 3.

Title: Weft replenishing mechanism
IPC: D03D47/26
Filed: 1979-02-23
Abstract: A weaving loom comprises carriages 7 carrying weft bobbins 11. The carriages 7 are circulated round a closed path which includes a weaving zone through which the bobbins 11 are driven to insert weft threads. When the yarn supply of a bobbin 7 is exhausted, that bobbin is automatically replaced by a fully- loaded bobbin. A sensor 12 produces a signal when it is passed by a carriage 7a bearing an empty, or nearly empty bobbin. This signal causes the empty bobbin to be ejected. After a delay which gives the empty carriage enough time to pass round the path to a region m-m, a distributor 19 transfers a fully-loaded bobbin from a creel 15 to the empty carriage 7. There is provision for the grasping of thread ends of the yarns of the bobbin while they are in the creel 15 and during transfer by the distributor 19, so as to avoid tangling. <IMAGE>

Filed: 1979-10-05
Abstract: A two-member valve plug comprises a lower plug member 23 and an upper plug member 22 which are in a generally axially spaced relation on the valve stem. Packing 35 is held in a snug-fitting condition between the lower and upper plug members by an axially resilient member 41 which acts between one end of the valve stem and the valve plug to urge the lower and upper plug members together. When the two-member valve plug closes a fluid passage, a force is transmitted by the valve stem directly through the upper plug member to the packing to form a leak-tight seal for the valve plug. The stem force is also transmitted through the packing and lower plug member to generate a seating force between the valve plug and a seat 17. <IMAGE>

Title: Dual Waveform Display
IPC: G01R13/40
Filed: 1980-04-30
Abstract: Two waveforms to be simultaneously displayed are sampled, digitized and stored. An electro-optic display, e.g. liquid crystal or electro- luminescent has a first m set and a second n set of matrix electrodes, cartesian or polar. In one form the m electrodes are divided into subsets of odd mo and even me rows X. Coded waveforms VI, each having a different shape over a period T are applied to subset mo whilst another e.g. median voltage is applied to subset me followed by the converse. Selected ones of the coded waveforms VI are generated and applied to the n electrodes Y, the choice being related to successive stored sample values of the two traces and the order of coded waveforms on the m set of electrodes. Traces are therefore displayed at intersections where the same voltage waveform occurs periodically and simultaneously on both electrodes, making the r.m.s. p.d. access the element below the critical level. <IMAGE>

Title: Storage cabinet
IPC: E05B65/463
Filed: 1980-07-21
Abstract: In an autolock mechanism in a storage cabinet having a plurality of drawers one above the other, a risk of jamming all the drawers closed is avoided by presenting on each drawer a cam surface 1 on a spring cam 2. Normally when the opening of a drawer begins, the cam surface 1 lifts a tag on a locking bar so that other tag(s) on the bar enter recess(es) 7 on the other drawer(s) to hold them closed. If a tag gets caught beneath a corner 13 to prevent the bar from rising so tending to prevent any of the drawers from opening, any drawer can be opened by pulling the drawer to cause its cam surface 1 to yield beneath the associated tag. <IMAGE>
