Title: Improvements in or relating to stabilizers for natural and synthetic rubbers
IPC: C07C37/14
Filed: 1949-06-17
Abstract: Highly alkylated cresylic acids obtained by alkylating a cresylic acid fraction with an olefine of 3-8 C atoms, followed by further alkylation with an alkyl halide of 3-8 C atoms using a Friedel-Craft catalyst are used for stabilizing by customary methods, before or after curing, synthetic rubbers of the following types: butadiene-styrene and -acrylonitrile copolymers, 1 : 3-butadiene, isoprene, 2-cyanobutadiene, pentadiene, p  cyclopentadiene, piperylene, dimethylbutadiene, and 2-methylpentadiene polymers; copolymers of dienes and substituted styrenes, vinyl naphthalene, vinyl diphenyl, vinylcarbazole, 2-vinyl-5-ethylpyridine, 2 - ethyl - 5 - vinylpyridine, and generally, compounds of the formula CH2=C(R)X where R=chlorine, Me, Et, Pr, or H, and X= CN, CONH2, COR1 or COOR1, R1 being alkyl of 1-5 C atoms.  Examples and Tables give the effect of such stabilizers on the properties of a 1 : 3 butadiene/styrene, after curing, compared with commercial stabilizers; and also on a butadiene-acrylonitrile copolymer.ALSO:Highly alkylated cresylic acids are obtained by further alkylating the reaction product of an olefine or mixture of olefines of 3-8 C atoms and cresylic acid, with an alkyl halide of 3-8 C atoms in presence of aluminium or boron halides.  In an example, a cresylic acid fraction alkylated with isobutylene in presence of sulphuric acid, is further treated with tert.-butyl chloride in presence of aluminium chloride to give a product having valuable properties as a stabilizer for natural or synthetic rubber compositions.  Tables give the results of tests on GR-S, BA and natural rubber.

Title: Voltage regulation arrangement for contact converters
IPC: H02M1/26
Filed: 1957-05-22
Abstract: 822,530. Rectifying. BROWN, BOVERIE & CIE A.G. May 22, 1957 [May 24, 1956], No. 16284/57. Class 38 (2). A contact converter with switching chokes 11, 12, 13 having control windings b, d carrying constant A.C. and variable D.C. respectively, has in parallel with its contacts 21, 22, 23, circuits including valves 31, 32, 33 and impedance 7 so arranged that at the instant of contact opening the current flowing through the parallel circuit is equal in value to that flowing through the saturable reactors whatever the value of control D.C. and consequent setting of magnetic phase angle control. The valve anode voltages are derived from transformers 41, 42, 43 energized from the main A.C. supply through transformer 17 and D.C. generator 14. The control D.C. and valve anode voltage are thus varied together as resistor 9, which is in series with starting rheostat 10 in the supply to exciter 15 of motor 16, is controlled by the output of D.C. transformer 8 in a connection to the main rectifier load 3. The voltage or power output characteristic of the rectifier is thus determined by the control D.C., and it is shown by means of diagrams (Figs. 3-6, not shown) how, as the value of the positive current steps varies with change in the control D.C., the value of current in the parallel circuits changes in agreement. The grid voltages of the valves 31, 32, 33 comprise bias from the D.C. exciter 15 and voltage generated in windings C on the switch chokes. The generator 14 may be replaced by a transductor (Fig. 2, not shown).

Title: Improvements in loading or excavating devices
IPC: E02F3/34
Filed: 1949-06-21
Abstract: 690,548 Scoop-arm excavating machines. DAVIES, E. W., and BAKER & SONS (FOUNDRY & ENGINEERS), Ltd.; T. June 21, 1950 [June 21, 1949], No. 16436/49. Class 68(i) [Also in Group XXX] In a scoop-arm excavating attachment for a tractor, the arms e, which are pivoted to the tractor at f and carry a bucket k, are luffed by links p and levers w which are pivoted to the arms e at x and are actuated by hydraulic thrustors d, the initial movement of the links p being arranged to tip the bucket on its heel before lifting.

Title: Improvements in or relating to magnetic transducer assemblies
IPC: H03F1/50
Filed: 1962-07-24
Abstract: 1,022,191. Magnetic cross-field recording &c. heads. I.I.T. RESEARCH INSTITUTE. July 24, 1962 [July 24, 1961], No. 16443/62. Heading G5R. [Also in Division B3] A cross-field record/playback or erase-record/ playback head, Fig. 1, has a beryllium-copper cross-field gap longer than the intermediate polepiece 27 separating the cross-field gap from the record/playback gap 31. The gap-spacer 31 of 0À00005 inch Be-Cu the pole 27 of À001 inch Permalloy and the gapspacer 30 of À002 inch Be-Cu are all extended beyond the track-width of the polepieces 50, 60, Fig. 2, and cemented at recesses 91-93 away from the transducing regions so that there is no risk of bulging due to cement increasing the gap-lengths. The members are assembled to supports 51, 61 and clamped into screening cans by means 81, 83.  Where paired, stereo assemblies are mounted into one can, Fig. 17, a continuous inter-track screen 503 may be fitted, or (not shown) the intermediate members, carrying no windings, may be extended continuously across the head. On playback, the dual pick-up at gaps 30, 31, Fig. 1, may produce null-points in the frequency response, Fig. 18, at critical recorded wavelengths (curve 212), so an impedance means 111 is brought into use on playback to balance out the conflicting fields (curve 213). A number of local circuits are detailed (Figs. 4-11, not shown) to achieve this. The three-pole head of Fig. 1 may erase as well as record when fitted with a short-circuited turn 99 in a gap at 100 in the pole 35 to concentrate the erase field. The third core members (473, Fig. 17; 522, Fig. 19) which define the record/playback trackwidths may be narrower than the erase sections of the heads. In Fig. 19, additional coupling between the cross-field and recording gaps is achieved by electrically connecting their eddy-currents by conductors 510. In Fig. 20, a separate erase gap 610 precedes the cross-field and record/playback gaps 612, 613 in a four-pole head, while in Fig. 14 (not shown), a double erase gap is provided with the erase winding mounted on an intermediate polepiece 401. In Fig. 20, the polepieces are formed into channel sections from 0À005 inch Permalloy which are annealed after forming and which are subjected to less stress on assembly than would occur in clamping stacked laminations. This last feature is claimed in Specification 1,022,192.

Title: Improvements in electric signalling systems for use for example in mines
IPC: B66B19/06
Filed: 1945-06-29
Abstract: 594,500. Electric selective signalling. GENERAL ELECTRIC CO., Ltd., and RICHARDS, S. W. June 29, 1945, No. 16628. [Class 40 (i)] In a signalling system, particularly for use in mines, wherein " go " and "stop" visual indicators L, N at a station A are each set up by individual hold-on relays F, K actuated by the corresponding "go" and "stop" switches G, S at a station A1, the " go " relay F is releasable by a switch B at station A and the "stop" relay K when once set up is releasable only from the station Al by operation of the "go" switch G. The invention is described as used in a mine wherein the onsetter and his assistant who control the respective landings corresponding to the decks of a two-deck cage are represented by stations A and A<1> respectively. The chief onsetter may signal "go" to the chief banksman and to the engine winder by closing a switch B, only after the visual " go indicator L has been set up by his assistant operating his " go " switch G. Actuation of switch G energizes relays F, H in series, relay H closing contacts to ring a warning bell J. Relay F is mechanically latched in its operated position and on release of the go " switch by the assistant onsetter the "go" indicator is lit over back contacts of switch G and relay K and contacts of relay F. Should the " stop switch S be operated by the assistant onsetter, relay H is energized in series with winding K1 of relay K. The bell J rings as before and the " stop " signal lamps N are energized over back contacts of the "go" switch G and front contacts of relay K which is locked by winding K2 energized in parallel with the "stop" lamps N. The contacts of relay K at the same time break the circuit to the " go " indicator to extinguish the "go" signal should this have previously been set up. These conditions obtain until the assistant onsetter operates his "go" switch when the relay K is released to extinguish the "stop" signal and the " go " signal is operated as described above. Subsequent operation of switch B by the chief onsetter energizes a winding M in series with the "action" signalling circuit over lines 1, 2 to the chief banksman and engine winder, to release the relay F to extinguish the "go" indicator. Similar arrangements may be provided for signalling between the chief banksman and his assistant.
