The main valve is opened periodically inducing subatmospheric pressure in the collecting conduits while the shoots communicating therewith are closed to the atmosphere, in order to remove from the collecting conduit refuse accumulated at the foot of each shoot. In the figure, refuse is inserted via inlets 4, each inlet being in a separate house 1. The refuse collects in widened portion 6 and collecting conduit 3 and is removed via a main suction conduit when valve 10 is opened. Check valves 12 close when pressure in vent pipes 11 is subatmospheric.

Abstract: 1,149,591. Velocity - modulated tubes. VARIAN ASSOCIATES. 7 Sept., 1966 [13 Sept., 1965], No. 40041/66. Heading H1D. In a high frequency discharge tube incorporating a slow wave structure and a lossy attenuator member, the latter is sandwiched between a pair of spaced, conductive wall members, at least one of which forms a confining surface for a fluid coolant flow channel and is deformable by the pressure of the flowing coolant to maintain the attenuator member in position in the slow wave structure, whereby brazing of the attenuator to the slow wave structure may be dispensed with. In a travelling wave tube housing a clover leaf slow wave structure provided with a pair of adjacent sever sections 16, 17, Fig. 3, intermediate its ends, each sever section is provided with four discs 20, 21 of lossy material retained within, and in good mechanical and thermal contact with, recesses formed in the inwardly radially directed fingers (33<SP>1</SP>, Fig. 2, not shown) of the clover leaf structure by the pressure of the thin flexible sidewall 25 of the coolant channel 28 when coolant is passed through the latter. Various methods of interconnection of the coolant channels for the different lossy discs are described, and in an alternative embodiment (Fig. 4, not shown) single coolant channels are interposed between and apply pressure to the lossy discs of both of the sever sections 16 and 17.

Title: Process and apparatus for the making and filling of flexible tubes to form sterile packages
Inventor: LUTHER DR JUSTUS
IPC: B65B9/20
Filed: 1959-11-27
Abstract: The apparatus of the parent Specification is modified in that a substantially constant gas pressure is maintained in the tube above the liquid level during the packaging process.  The sterile gas, introduced after steam sterilisation, passes through reducing valves and through a pipe having extending downwards therefrom an elongated branch, the lower-end preferably transparent of which opens under water at a substantially constant level in a tank, also preferably transparent.  Increases in the gas pressure are dispelled by blowing into the water, and decreases cause the water to rise in the branch. The liquid level in the tube is controlled by means such as that described in Specification 931,254.

As shown, a moving fibrous web 10 is coated with a curable rubber adhesive from a hopper 14 and then with flock fibres 12 from a hopper 28 vibrated by a hexagonal beater bar 30. The web is then passed through a curing oven 32 after which the process may be repeated to flock-coat the other side. The singly or doubly coated web is drawn by rollers 36 through a bath 34 containing an acetone solution of nitrocellulose and through a precipitating bath 38 of water, is dried in a chamber 40, and rolled up at 42. The bath 34 may be replaced by a bath of polystyrene latex furnished with a doctor blade, the bath 38 being dispensed with.

Abstract: 1,119,673. Digital word generator. INTERNATIONAL BUSINESS MACHINES CORP. 24 Sept., 1965 [28 Sept., 1964], No. 40711/65. Heading G4A. A word generator comprises a word-modifying logical matrix interconnecting two registers, to produce in the second register a modified version (determined by selectable preconditioning of the matrix) of the word in the first register, the word in the second register being enterable into the first register for cyclic operation to generate a sequence of words in the second register. A computer or the transmitter and receiver of a communication system may each comprise an m-sequence generator as follows to select bit positions to be associated with individual check bits. An operator presets an A-register and two further registers according to the required first word of the sequence, the number of words in the sequence and the number of times the sequence is to be repeated, respectively. During operation, the A-register controls the setting of a B-register via a matrix of gates controlled by switches preset by the operator in accordance with the Boolean equations to govern the generation. The B-register in turn controls the A-register and its output is sampled to provide the m-sequence. Clock-pulse-driven counters are compared with said further registers to control length and number of sequences.

The said solutions are stated to result in an improvement in the chemical stability of the salts of the sulphonium inner salts and may be obtained by adding to aqueous solutions of the salts a weak acid or an ammonium, alkali or alkaline earth metal salt of a weak acid and adjusting the pH to a desired value.  Weak acids which are used are monobasic acids with a pK value not less than 2.0 nor greater than 5.0, for instance formic acid (pK 3.7) and acetic acid (pK 4.7) and polybasic acids with a pK value for the first hydrogen not less than 2.0 nor greater than 5.0, for example phosphoric acid (pK 2.15), citric acid (pK 3.1), tartaric acid (pK 3.0), succinic acid (pK 4.0) and maleic acid (pK 2.9). The amount of the weak acid or salt of a weak acid added to the aqueous solution is a small percentage of the weight of the solution preferably from 0.25% to 5%.

The same is true of channels I 2 -I 4 , with corresponding transducers coupled to channel interfaces 30, 40 there being substantially no cross correlation between channels. A clock code is also carried via line 35, and is used to gate the channels so that sidelobes in the response patterns of the transducers are not communicated. The clock code frequency is an integral sub-multiple of the data channel code frequency. Line 35 may couple the central processing unit, and other units, of a computer. The operation of the transducers 32, 34, 36, 38 on quartz or lithium niobate substrates 31, 37 is discussed in the specification. The surface wave devices, in view of the lateral extent of transducers 34, 36 enable the summation to form the multiplex signal to take place.

Abstract: 936,058. Pulse separating circuits. ROTAX Ltd. Aug. 2, 1962 [Nov. 23, 1961], No. 41892/61. Class 40 (6). Simultaneous pulses which may occur in separate lines are retransmitted in the lines with the pulses separated in time. In the Figure, input pulses are applied to lines 1 and 2 and retransmitted at lines 11 and 12 while an alternating control wave is applied at 5. When a pulse occurs only at 1 the bi-stable circuit 3 is changed over to provide an input to the NOR circuit 7. If there is no input from the bistable circuit 6 or from a monostable circuit 10 the NOR circuit produces an output pulse which triggers a monostable circuit 9 to produce the desired retransmitted pulse at 11 and to produce a further pulse to restore the bistable circuit 3. Similarly, if a pulse occurs only on line 2 an output pulse is applied to line 12. If, however, simultaneous or overlapping pulses occur only one NOR gate, depending on the condition of the bi-stable circuit 6, is in a condition to provide an output pulse to operate the monostable output. When the corresponding monostable circuit has completed its operation the output from that circuit to the other NOR circuit terminates and as the bistable circuit 6 by this time has been changed over the other NOR circuit will initiate an output pulse on the other line. Thus the two input pulses are now spaced by the operating time of the monostable circuit.
