Title: Improvements in and relating to epoxide resins
Inventor: YOUNG ERIC WHICHELL
IPC: C08G59/42
Filed: 1966-04-21
Abstract: Epoxy resins have their hydroxyl content reduced by reaction with an ester <FORM:1115578/C3/1> in which R1 is hydrogen or an alkyl, aryl, alkenyl or aralkyl radical; R2 is a C1- 6 alkyl or alkenyl radical; and R is a chlorine atom or a radical -COOR3 where R3 is a C1- 6 alkyl or alkenyl radical, or a radical -COR4 where R4 is an alkyl, alkenyl, aryl or aralkyl radical. Examples of suitable esters are ethyl acetoacetate and ethyl chloroacetate.  Reaction may take place in the presence of a large excess of the ester; the remainder of which is distilled from the treated epoxy resin at the end of the reaction.  A basic catalyst, e.g. an alkoxide of an alkali or alkaline earth metal may be employed.  Conventional hardness may be used to cure the modified resin.

Filed: 1928-06-18
Abstract: 311,580. Smith, A. F., and Harrison, W. B. June 18, 1928. Rotary-mould-table machines ; tamping; feeding-machines.-Concrete bricks having a core of cheaper material are made by utilizing the core tube surrounding the core material as a forcing ram to feed and position the facing material so that it surrounds the core material when the core tube is withdrawn. The manufacture is carried out in three stages, the moulds being mounted on an intermittently-rotating table a<1>, Fig. 4, and filled at F, tamped at T and extracted for delivery at E. At the filling station the moulds a register with the mouth of the hopper d into which the facing material is delivered. The larger part b<1> of the core tube b fits the lower part of the hopper and acts as a plunger to feed the facing material downwards as the core tube descends into the mould. The core material is delivered into the lowered tube and remains inside the facing material as the core tube is withdrawn. At the tamping station the material is subjected to the pneumatic hammer e, Fig. 3. The hammer can be raised or lowered bodily to engage and free the moulds by the rods f<1> which carry the lifting-member f. At the delivery station a stamp or plate is lowered on to the brick to hold it while the mould frame is raised up and removed by hand. The brick and pallet are then delivered and a new pallet supplied by the apparatus shown in Fig. 5. The thrust of the cam-actuated rods s removes a pallet from the bottom of the pile c and at the same time pushes the brick g and its pallet into the dotted line position.

Abstract: 1,029,834. Geophysical prospecting. SEISMOGRAPH SERVICE (ENGLAND) Ltd. May 8, 1962 [May 8, 1961], No. 17583/62. Divided out of 1,029,833. Heading H4D. [Also in Divisions G1 and G5] In a seismic survey system, the reflected signal is correlated with the transmitted signal by means of a correlation detector of the type described in Specification 1,029,833 (Division G4) comprising a magnetic head 10 writing information on to a tape 4 and a play-back head 12 of extended length carrying a conducting trace which represents the transmitted signal. In a system used in the sequential processing of several channels of seismic information the reflected signal, resulting from a transmitted swept frequency signal is recorded on one channel of a multi-channel drum 20, the channels being sequentially fed to the correlator 23 by means of a switch 21. The correlated output is fed to a CRT 27, a second multichannel recording drum 24, a camera 29 and a pen recorder 40. The uncorrelated signal is also fed to another trace on CRT 27. The reflected signal has a duration of approximately half the recording cycle, and the drum 24 therefore rotates at twice the speed of drum 20, the switch 36 closing during alternate revolutions of drum 24. Timing and a record of the transmitted signal tracks may be recorded and in order to ensure that the zero time pulse from every channel or drum 20 is recorded at the same place on drum 24 the relative timing between drums 20, 24 may be adjusted by a servomotor 43 which moves the head 12 in accordance with control signals derived from the position of the head itself and from the position of drum 24, this latter control signal being derived from potentiometer 46.

Abstract: 1340737 Making tubes; rolling FRIEDRICH KOCKS 28 May 1971 [23 June 1970] 17741/71 Headings B3M and B3A In a method of stretch reducing a tube 18 having weak points 14 where adjacent lengths are butt-welded together, the stretch reducing mill 2 is so controlled that the tension exerted on these weak points is reduced as they pass through the mill. This lessens the risk of fractures in the stretch reducing process. The tube 18 may be formed from lengths of seamless tube welded together, or (as shown) from strips 8 which are butt-welded together, are skelped by rollers 14, and seam welded by an induction welder 16. A heater 20 is followed by a detector 28 which senses the presence of weak points. An output signal from the detector is used to control an auxiliary motor 26 for the stretch reducing stands. The motor 26 modifies the driving speed applied to the stands by a main motor 24. Alternatively in the case where the stands are individually driven, the speeds of the stands can be suitably adjusted as the weak points pass them. A flying shear 22 finally severs desired lengths from the tube.

Title: Improvements in or relating to apparatus for generating amplitude modulated electricpulse trains
IPC: H04J3/04
Filed: 1954-06-16
Abstract: 747,071. Multiplex pulse signalling. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 16, 1954 [June 17, 1953], No. 17756/54. Class 40 (5). A trochotron tube 6 produces interlaced pulse trains at terminal 9 amplitude modulated by channel signals applied to transformers 1 ... 4. By connecting the individual compartment control electrodes 21 ... 24 to the corresponding electrodes of a distributer trochotron (not shown) and synchronously controlling the current from cathode 7 by pulsing the control grid 8, pulses are produced in succession from the auxiliary electrodes 31 ... 34 connected to the output terminal 9. The amplitude of these pulses depends upon the signal potential applied to the individual plate electrodes 11 ... 14, from the transformers 1 ... 4 respectively. Electrodes 11 ... 14 are suitably biased from a common source 5 and electrodes 31 ... 34 from source 15 through load resistor 10. The circuit may be modified by applying the modulating signals to the auxiliary electrodes 31 ... 34 instead of the plates and obtaining the output pulses from the plates or the control electrodes. Cross-talk between the channels may be reduced by feeding the channel signals through diodes biased to conduct only when the corresponding electrode current exceeds a predetermined value. Alternatively, or in addition, the output pulses from each compartment may be fed through a normally non-conducting diode which conducts only when the corresponding electrode current exceeds a predetermined value, Fig. 4 (not shown).
