Title: Improvements in or relating to conveyors for carrying flax or other fibrous materials through scutching, hackling, and similar machines
IPC: D01B5/00
Filed: 1930-09-22
Abstract: 354,101. Conveying flax &c. in scutching or heckling machines. BOBY, Ltd., R., St. Andrews Ironworks, Bury St. Edmunds, Suffolk.-(Assignees of Soenens, M. ; 1c, Boulevard de Smet de Naeyer, Courtrai, Belgium.) Sept. 22, 1930, No. 28316. Convention date, Nov. 2, 1929. [Class 120 (i).] In a belt conveyer of the kind described in Specification 245,511, [Class 120 (i), Spinning, Preparation &c. for], for carrying flax or other fibrous materials through scutching, heckling or like machines a supporting device 5, Fig. 1, is adapted to fold the flax 2 round the part of the belt 1 nearest thereto and clamp it so that an increased drag on the pendent portion 9 increases the grip. The clamping device 5 is formed as a flange on the fixed guide 4 in which the belt 1 is arranged to travel and a holding-flange 6 is provided to act as a second clamp. Alternatively the belt is retained in the guide 4 by a separate plate 10, Fig. 2. The flanges 5, 6 are bevelled at the entrance to the groove 3, Fig. 6, so that the material is progressively folded round the belt 1, while, if desired, the stalks 2 may be shaped by a grooved pulley 14, Fig. 3, before entering the guide 4.

[A Specification was laid open to inspection under Sect. 91 of the Acts, April 18, 1936.] [Class 99 (ii)] [See also Groups XXXVI and XIX] In order to determine losses in a distribution system for gas, water and the like, including a main meter at the supply station and consumer meters at each consumer station, printing or recording devices operating in response to an impulse represented by variations in the pressure of the commodity consumed are provided at each meter, and means are associated with the system for sending therethrough, by way of the said commodity, an impulse operating simultaneously on all the meters. In the case of gas distribution, reservoirs of gas at different pressures are provided, one at the normal supply pressure and the other at the increased pressure for giving the impulse. A printing device for a gas meter 22, with shaft 24 geared to numeral rollers 26 with raised numerals is shown in Fig. 3.

Abstract: 519,743. Valve amplifying circuits. KOLSTER-BRANDES, Ltd., and CHATTERJEA, P. K. Sept. 30, 1938, No. 28479. [Class 40 (v)] An amplifier for slowly fluctuating unidirectional voltages comprises a valve with a source of alternating current applied to a negative control grid and connections for applying the fluctuating voltage to a second low potential control grid and means to rectify the output and select therefrom the direct current component with. its low frequency fluctuations. The Figure shows a frequency changing type of valve with a source S connected to the grid Gx1 ond the fluctuating voltage connected. to the grid Gx2. A delay voltage may be applied to the rectifier D to adjust'the sensitivity and the output, as shown, is selected by high and low pass filters HPF, LPF respectively. The source may be the local oscillator of a superheterodyne receiver at the fundamental or a harmonic frequency. The arrangement may be used to amplify automatic volume control voltages in a wireless receiver or to permit amplitude instead of frequency selection in multi-channel signalling or in connection with vibration tests.

Title: Process for the preparation of a stabilizer to be blended with synthetic resin
IPC: C08K9/04
Filed: 1965-07-06
Abstract: Stabilizers for halogen-containing synthetic resins are prepared by adding a metallic finely divided synthetic resin stabilizing agent to a molten metallic soap which is a lubricant and stabilizer for the resin and if not already in particulate form, converting the mixture into a wholly particulate form, the ratio of soap to stabilizing agent being such that the particles of the latter are coated with a continuous phase of the former. Specified metal compounds are sulphates, carbonates, phosphates, phosphites, titanates, oxides, stearates, laurates and phthalates of cadmium, barium, calcium, magnesium and lead.  Other ingredients such as viscosity reducers, e.g. fatty acids, esters, amides and alcohols and paraffins; and colouring agents, e.g. titanium white and carbon black; may be incorporated in the molten soap.  The products may-be solidified and granulated, pelletized or otherwise subdivided, preferably to a particle size of the order of the resins in which they are to be incorporated. Specified resins are polymers and copolymers of vinyl and vinylidene chlorides, which may be plasticized, e.g. with dioctyl phthalate.  In examples stabilizers are prepared by blending lead stearate (which may be formed in situ from lithage and stearic acid) with (1 and 3) tribasic lead sulphate, (2) dibasic lead phosphite, (6) barium stearate, (7) dibasic lead phthalate and tribasic lead sulphate, (8) tribasic lead sulphate and cadmium stearate, (9) dibasic lead stearate, calcium stearate and tribasic lead sulphate, (10) calcium stearate, tribasic lead sulphate, titanium dioxide, carbon black and hardened beef tallow, and (11) stearic acid, hardened castor oil, calcium stearate, barium stearate, carbon black and tribasic lead sulphate; and by blending (4) calcium stearate (formed in situ from calcium hydroxide and stearic acid) with dibasic lead stearate and (5) cadmium stearate with white lead.

In a pinking attachment according to the parent Specification, the ledger blade 26 is angularly adjustable in its own plane relative to the rotary cutter 50 to permit accurate align-. ment of the shearing edges. The blade is housed between a base 16 fixed to the machine bed and a guide 20 having a bearing 30 for the cutter. Rabbets in the guide permit limited transverse movement of the blade by means of an adjustable sliding bar 68 having vertical knife edges engaging the blade. A bore 51 in the cutter co-acts with a bearing-point 46 on the nose piece 36 of the blade and the cutter and blade are held together by a tensioning-device 62.

Abstract: 1311215 Monostable transistor circuit MOHAWK DATA SCIENCES CORP 16 June 1970 [23 June 1969] 29228/70 Heading H3T A monostable includes two NAND gates 3, 7 with a time delay 8 having an integrating function, and an inverter 9, all connected as shown. Input 1 and output 2 are normally high so that lines 5, 6 are low; line 11 is high being inverted by 9 relative to lines 5, 6. A negative input 1 makes lines 5, 6 high so that lines 5, 11 are both high for the period of the delay. Thus NAND 7 has two high inputs and output 2 is low. After the delay, line 11 goes negative and output 2 reverts to a high state. When the input 1 returns to the high state, the circuit resets with no output at 2 since the NAND 7 is not responsive to two low inputs.
