Abstract: 1,233,148. Electronic counters. STARKSTROM - ANLAGENBAU KARL - MARXSTADT VEB. 3 June, 1969, No. 28046/69. Heading G4A. An input circuit to a reversible counter comprises a pair of flip-flops FF1, FF2 receiving the pulses 1 to be counted while the true and inverted reference pulses 2, 2, are applied to FF1, FF2, respectively. Assuming the waveforms of Fig. 1, at time t 1  the trailing edge of pulse #2 reverses FF2 to produce an output L. NAND gates U1, U3 therefore produce outputs O, L, respectively, the latter being applied at AZ to the counter. At the same time FF3 is operated to mark the reverse count lead AR. FF2 restores via delay line VZ2 and terminates the output at AZ. The action repeats for every trailing edge of pulse 2 to produce an output J, Fig. 1. If now the pulse sequence 2 leads pulse sequence 1 the trailing edge of true pulse 2 reverses FF1 to produce a count pulse at AZ and marking of forward terminal AV, while the trailing edges of the false pulses 2 have no effect. An output Jd, double the frequency of J, can be produced by a modification, Fig. 3, in which the inverse of the count pulses #l is applied to further flip-flops FF4, FF5 so that the trailing edges of 2 and 2 are both effective on one or other of two AND gates U1, U2 and so on the count terminal AZ and the appropriate direction terminal.

A nozzle 9 of a desurfacing unit forming an acute angle with a workpiece is adjustable between two angular positions, one for initiating the desurfacing operation to limit the depth of the molten pool, and the other for normal operation of the unit. The nozzle 9 is mounted on a lever 13 which is pivoted at 12 to an arm 11 of a horizontally displaceable carriage 7 and to a piston-rod of an air cylinder 14. To initiate the desurfacing operation, a switch (K) (Fig. 4, not shown) is operated to start a motor (M) of an ignition wire feeder 19 and to actuate a solenoid (S 1 ) which operates a cylinder (22) (Fig. 3, not shown) for supplying oxygen to the nozzle 9. After a certain amount of ignition wire 17 has been fed which is controlled by a timer relay (T 1 ) cutting off the motor (M), a solenoid (S 3 ) is operated by a timer relay (T 2 ) to cause the piston-rod of the air cylinder 14 to be extended and to swing the nozzle 9 from the dotted to the full line position. Thereafter the nozzle 9 is moved along the surface of the workpiece. The carriage 7 is supported in a carriage (6) (Fig. 1, not shown) vertically movable in a frame (4) carried by a horizontally displaceable substructure (1). The workpiece may alternatively be displaced relative to the desurfacing unit.

A synchronous electric motor energized through a frequency changer is controlled by sensing the flux in the stator core at locations spaced round the stator circumference. The sensors, 3, 4, 5, shown, each comprise two windings surrounding respective portions of the stator core.

The other winding of each sensor is connected to a signal comparator 6. Depending on the instantaneous rotor position the core portions at the sensors 3, 4, 5 will be subjected to different flux densities so that on application of a pulse from generator 7 the sensors provide signals of different amplitudes to the comparator 6, these signals indicating rotor position. The comparator 6 controls the frequency changer feeding the stator windings.

Abstract: 1,265,665. Laminar signs. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 Dec., 1969 [3 Jan., 1969], No. 477/69. Heading B5A. [Also in Divisions C3 and G5] An injection-moulded light-transmissive laminar sign (bearing lettering or decoration) is mounted in front of a light source so that it is illuminated from behind, and comprises a translucent foamed pigmented polymethyl methacrylate core surrounded at least at all points away from the sprue area of the moulding by an unfoamed surface skin of translucent opalescent polymethyl methacrylate. The sign may be bowl-shaped and enclose the light source, or the light source may be accommodated entirely within a trough-shaped sign. The sign is produced by injecting a first charge of methacrylate into a vertical flash mould and then injecting a charge of the foamable methacrylate through the same injection orifice into the first charge, allowing the foamable methacrylate to foam, and returning the materials in the mould until they have set. A second charge of methacrylate may be injected after the foamable methacrylate to avoid a foamed surface at the point of injection. The foamable methacrylate may be injected at a temperature at which the gas causing foaming is generated but under such pressure and at such a high speed that foaming is prevented before the mould is filled, and the mould is then enlarged instantaneously, or gradually by relaxing the forces locking the mould or by mechanically opening the mould. Alternatively the halves of the mould are urged together to distribute the first charge of methacrylate and then the foamable methacrylate is injected. Alternatively, the injected material may only fill the mould after foaming.  The polymethyl methacrylate may be a homo- or copolymer of methyl methacrylate, e.g. ethyl acrylate copolymerized with methyl methacrylate. The surface skin contains titanium dioxide or barium sulphate. The foaming agent may be a liquid activated by heating, e.g. methyl or ethyl or vinyl chloride, or the polyhalocarbons, or volatile hydrocarbons such as pentane. The blowing agent may be a solid activated by heating and dry mixed with powdered pigmented methacrylate, or hot compounded therewith in a two-roll mill or in an extruder and then chopped. Solid blowing agents include sodium bicarbonate, azodicarbonamide, dinitroso-pentamethylene tetramine, p,p<SP>1</SP>-oxy-bis-(benzene sulphonyl) hydrazide, and benzene-1,3-disulphonyl hydrazide. From 0À01 to 5% of the weight of the pigmented methacrylate of blowing agent is used.

A linear polyester is produced by the controlled reaction of an epoxide, a polycarboxylic acid anhydride and a lactone in the presence of an etheriflcation inhibitor and preferably an initiator containing at least one active hydrogen atom attached to sulphur, oxygen or nitrogen, to give a polyester having at least 80% of its repeating groups comprising polyester groups of the type and polylactone groups of the type joined to the polyester groups by ester linkages, wherein x and y are small integers whose values are not biased by the position of the polyester or polylactone groups along the chain and A, E and X are the residues of the anhydride, epoxide and lactone respectively. The corresponding acid, glycol and hydroxy carboxylic acid could be substituted for the above reactants to give the same residues. The reaction is controlled such that the epoxide, anhydride and lactone each react at substantially constant rate during the reaction. A portion of the groups "E" may be derived from an aziridine giving a polyesteramide product. The polyester, when hydroxyl terminated, may be reacted with a compound having at least two iso-cyanate groups to give an isocyanateterminated urethane prepolymer. Specified reactants are: epoxides-oxiranes or oxetanes substituted with alkyl or aryl groups which may be further substituted with alkyl, aryl, alkoxy, aryloxy or ester groups or chlorine; lactones-those containing a -(CH 2 ) n - or -(CR 2 ) n - chain where n is 4 to 7 and R is methyl, ethyl, n-propyl, isopropyl, hydrogen, chlorine or bromine, the total number of carbon atoms not exceeding 12 and the total number of halogen atoms not exceeding 2; anhydridesthose of dicarboxylic acids, possibly in admixture with those of tetra or hexa carboxylic acids.
