Title: A process for preparing a linear epoxy resin
Inventor: BARTRUM BASIL ECCLESTON
IPC: C08G59/50
Filed: 1967-03-22
Abstract: 1,141,935. Modified epoxy resin. DOW CHEMICAL CO. 22 March, 1967, No. 13522/67. Heading C3B. Linear thermoplastic resins are prepared by mixing substantially equimolar proportions of a diglycidyl ether of formula in which n is from 0-20 and a compound having only two amine hydrogen atoms which is either an alkanolamine or aniline; the mixture may be heated, e.g. at from 20-250‹ C. to complete the reaction. Reaction may take place in a solvent which is non-reactive under reaction conditions and the resin may be recovered by evaporation or precipitation. The resins may be used in the formation of fibres and films. The resins may be reacted with polyisocyanates or mono- or di-carboxylic acids to give resins with polyurethane or polyester linkages.

Abstract: 169,210. Stack, G. F. May 20, 1920. Variable-speed friction gearing.-In gearing of the kind in which the frictional engaging pressure is varied as required, the gear is so constructed that the fulcrum of a lever is moved as the speed is changed. A disc 2 is pressed against a roller 1 by a lever 13 loaded by a spring 14 and tending to turn about a fulcrum 16. The roller 1 is connected by links 4, 17 and a lever 3 to the fulcrum 16, so that the roller and fulcrum move together. The fulcrum 16 is supported by a plate 15 having a recess 24 corresponding to disengaged drive. An arrangement for adjusting the plate 15 automatically is described. If, owing to wear, the lever 13 takes the position shown in Fig. 6, changing gear causes the lever 13 to oscillate. A pawl 21 on the lever 13 acting on a ratchet 22 then feeds the plate 15 to a parallel position.

IPC: F42B19/10
Abstract: 143,456. Thompson, W. P., (Bethenod, J.). Sept. 9, 1919. Wireless control of distant apparatus. - A vehicle, vessel, or an aircraft or like object to be steered by wireless is provided with a transmitting-aerial communicating with two directive receiving-systems so placed that while the object is in its correct course the reception at the two stations will be of equal strength. The received signals are transmitted over telephone lines to a centrally-situated control station from which control waves are sent to the movable object so as to divert it towards its correct course until equality of signal strength is again observed. The wave emission from the movable object is received on two fixed directive receiving-systems 1, 2 which are placed symmetrically with regard to the correct course 3, 4, and are arranged to receive with equal intensity signals emitted from any point on that course. The signals are communicated along telephone lines to the control station 3 from which control radiation is emitted whenever the signal strengths are unequal. In order to test for the equality of condition of the aerials 1, 2 and the telephone lines connecting them to the station 3, a fixed transmitting-aerial 5 is arranged in the line of the course 3, 4.

The content of the enabled selector switch is fed to adder 87 of binary rate multiplier 61 receiving a pulse input from OR 77, the input  pulse rate being modified in proportion to the  content of the enabled feedrate selector; the carrying output of the adder being connected to AND 88 receiving also the input pulses; and feed via binary coded decimal up/down counter 90 to decoder drive 91 controlling electrohydraulic pulse motor 10 moving the grinding wheel support 11. Operation (i) A start signal on lead 25 causes controller 13 to enable switches 40, 38 and enable, via OR 72 and AND 70 the passage of 400 KHz pulses to multiplier 61 providing a "sidewall" feedrate. (ii) when, in accordance with a programme, enabling signal 14 is replaced by 15, a "fast approach" feedrate, preset on selectors 41, 42, is established (iii) subsequently a "number one" feedrate is established. (iv) on replacement of "number one" by "number two" feedrate, via divider 65, and AND 78, a 40KHz pulse input, is provided to multiplier 61, adder 87 receiving the content of selectors 52, 53, and a spring biased probe 21 contacts the workpiece W. When the probe, via analogue to binary digital converter 23, indicates that a slight oversize to the desired final diameter is attained, as detected in controller 13, "number two" feed enable signal 17 is replaced by "fine feed" enable 18, causing, via the divider 65 and AND 80, the transmission of 4-KHz pulses to the multiplier 61, as well as the content of selectors 56, 57. When the desired final diameter is sensed by probe 21, the grinding operation is terminated, possibly after a time allowance for "spark-out" grinding. The workpiece may be advanced instead of the grinding wheel support.
