Filed: 1944-03-03
Abstract: Symmetrical halogen substituted aryl ethanes of the general formula <FORM:0600350/IV(b)/1> (wherein Ar represents a fluorine-, chlorine- or bromine-containing aryl group of the benzene series, X represents hydrogen, chlorine or bromine and Y chlorine or bromine) are manufactured by the condensation, with the aid of a condensing agent (preferably sulphuric acid or oleum or mixtures thereof), of halogen substituted aryl compounds of the benzene series, containing replaceable nuclear hydrogen, with mono- or di-halogenacetaldehyde, its hydrate or a mono- or di-ether or di-ester or mixed ether-ester thereof.

Title: Improvements in or relating to dynamo-electric machines
Inventor: NICOLL WALTER LYON GORDON
IPC: H02K5/128
Filed: 1964-02-11
Abstract: 1,045,204. Dynamo - electric machines. LYON NICOLL Ltd. Feb. 11, 1964, No. 5686/64. Heading H2A. In a dynamo-electric machine substantially as defined by Claim 1 of Patent Specification 949,477, replacement of a stator field coil 21 is enabled by forming the stator in two parts, a main part 3 enclosing the rotor 2 and being encased in a water-resistant synthetic resin moulding 4, and an offset part 18 directly associated with the field coil(s) 21, the two parts being releasably interconnected by a dovetail connection which secures together adjacent mating surfaces 20a, 20b completing the magnetic circuit between the coil and rotor. In the pump motor shown, the part laminations 5, 19 are held together by rivets 5a, 19a, selfstarting is ensured by shading pole rings 23, and the moulding 4 is of acetal or epoxy resin or P.T.F.E. Embedded in the moulding at either or both ends are apertured end plates 6, 11, Fig. 1, not shown, through which the rotor may be withdrawn and which are closed by a cover plate and a pump lid respectively; alternatively, one cover plate may be integral with the moulding. The rotor axial and thrust bearing may be of P.T.F.E. and axially adjustable by a screw. The pumped water may circulate through a wire-mesh filter into the motor for cooling purposes, and in a submersible motor the moulding also encases the offset core part.

Title: Improvements in or relating to heat exchange apparatus
IPC: F28B1/00
Filed: 1954-02-26
Abstract: <PICT:0802009/III/1> <PICT:0802009/III/2> Two fluids between which heat is to be exchanged are each separately confined by a heatexchanging wall, the two said walls being separated by a space containing a volatile heat transfer liquid which is maintained as a thin film on at least a part of the hotter of the two wall surfaces and is evaporated from that surface.  In the preferred form bubbles of gas such as air (see Fig. 3) are passed through the heat transfer liquid and it is stated that the thin liquid film thus formed on the hotter wall 1 evaporates within the bubble and is condensed on the other wall 4 which is cooled by the cooler of the two fluids.  In Fig. 5 the lower cone of the mixing venturi of the contact condenser described in Specification 791,652 functions as a cooling unit being surrounded by a jacket 36 containing the heat transfer liquid to which air is supplied through a tube 38 and which in turn is surrounded by a jacket 42 through which the coolant flows. In this form the coolant in addition to receiving heat through the heat transfer medium, also cools the liquid directly surrounding the jacket 42.  The coolant jacket may be partitioned, Fig. 6 (not shown), so that two cooling media may be utilized, one of which may be fuel oil or boiler feed water.

Title: Improvements in synchronous motor clockwork
IPC: G04C15/00
Filed: 1951-03-09
Abstract: 690,653. Clocks. ETABLISSEMENTS E. JAEGER. March 9, 1951 [Feb. 12, 1951]. No. 5782/51. Class 139. A synchronous-motor electric clock comprises a pawl and ratchet device interposed between the rotor shaft of the synchronous motor and the clockwork train, a driving pawl of said device being reciprocated by an eccentric member rotatably driven by the synchronous motor and having a driving end surface so shaped that during the pawl movement towards the centre of the ratchet wheel the apex of the tooth next to be driven exerts a frictional retarding action upon said surface. A synchronous motor 16, 17, 18, Fig. 3, rotates a spindle 10 through reduction gearing. A pawl 6, Figs. 2 and 3, is reciprocated by a member 9 eccentrically mounted on the spindle 10 and steps-on a ratchet wheel 5 carried by the seconds shaft 26. The minutes spindle 33 is driven through gear train 27,.29, 30, 31 and friction clutch 32. The hour spindle 43 is driven through the gear train 34, 35, 36, 42. A pawl 7, Fig. 2, prevents reverse rotation of the ratchet wheel 5. A spring 21 interconnects the pawls 6 and 7 and urges them into engagement with the wheel 5. The effective ends 24, 25 of the pawls 6 and 7 are made flat so that their movement inwards to engage each successive tooth is retarded by the frictional engagement of the apex of the preceding tooth and the end surfaces 24, 25 respectively. The gear 35 meshes with a gear 37 on a spindle 38 which may be rotated by a knob for handsetting. The ratchet wheel may comprise a pair of steel toothed discs enclosing a plastic disc acting as a shock-absorber.

Title: Signal clipping system particularly for television
IPC: H04N5/08
Filed: 1944-03-29
Abstract: 581,018. Television; valve circuits. HASELTINE CORPORATION. March 29, 1944, No. 5845. Convention date, May 14, 1943. [Classes 40 (iii) and 40 (v)] A system for asymmetrically clipping an applied signal having recurrent peaks comprises a valve whose conductance is increased by the peaks of the signal fed with appropriate polarity and an anode impedance connected by passive coupling elements-i.e. elements which do not include any power amplifying devices-to the input of a second valve whose conductance is increased by the peaks of the signal together with means for causing the peaks to be stabilized in the input to the second valve, and the amplitude of the signal applied to the second valve is so related to its characteristic that anode current clipping is effected by the second valve. In the television system shown, the composite signal derived from an amplifier 16 is applied to a valve 30 having a coupling condenser 32 and a grid-leak resistance 33 with a time constant greater than the period of the synchronizing signals, thus stabilising the input to the valve 30. The anode of the valve 30 is connected to an impedance 38 and the signal output of the valve is applied to the cathode of the valve 35 having a load resistance 39 connected to its anode and a grid-leak resistance 36 and a condenser 37 in its grid circuit providing a time constant greater than the period of the synchronizing impulses. The amplitude of the signals applied to the second valve is so related to its grid voltage-plate current characteristic that anode-current clipping is effective to produce an output signal in which picture components are absent. The resistance 38 is high relative to the resistance 39 or to the sum of the resistance 39 and the minimum anode-cathode resistance of the valve 35. The use of the high resistance 38 increases the gain of the valve 30 during the interval between synchronizing impulses and since the tips of the synchronizing impulses are stabilized at the zero grid-voltage level of the valve 35, the picture frequency portions of the signal are shifted well below the cut-off point. The control electrode or grid of the valve 35 reduces the capacitative coupling between the anode and cathode and prevents the passage of video-frequency signals from resistance 38 to the output terminal 40 when the valve 35 is non-conductive.
