Title: Preparing organo manganese compounds electrolytically
IPC: C25B3/13
Filed: 1958-12-22
Abstract: 872,113. Organo-manganese compounds prepared electrolytically. ETHYL CORPORATION. Dec. 22, 1958 [Dec. 23, 1957], No. 41278/58. Class 41. Manganese cyclopentadienides are prepared by electrolysis using a manganese metal anode, and as electrolyte a metal cyclopentadienyl selected from Groups I, II, IIIA, IVA or IX. Preferably the metal compound is taken up in a solvent or complexing agent, e.g. diethylene glycol, dimethyl ether, tetra hydrofurane, hydrocarbons, pyridine, n-butyrolactone, acetals, dialkyl sulphoxides; or tri-ethyl boron complexed with an amine. Examples of metal compounds used are sodium alkyl cyclopentadenide, indenyl sodium, fluorenyl sodium and like compounds of other alkali and alkaline earth metals, Fe, Co, Ni, Cu, Zn, Cd or Hg. The electrolysis is effected under N, or in the presence of CO, or a carbonyl, e.g. Ni carbonyl, when the tri-carbonyl compound is formed. Current may be reversed from time to time, or may have an A.C. supply imposed thereon. Electrolysis is normally effected at 20 to 200 C., but lower temperatures are applied when liquid ammonia cooling is used. The electrolyte may include salts aiding conductivity, e.g. halides of alkali, alkaline earth metals, or Al, or complex hydrides, e.g. LiAlH2. Pure manganese as anode may be replaced by alloys, e.g. ferro-manganese, or with Ni, Cu and Zn. In examples, dienides having 5 to 12 carbon atoms are preferred products, e.g. manganese n-octyl cyclopentadienide and the corresponding phenylcyclo-, indenyl, fluorenyl compounds, and tri-carbonyl compounds, e.g. cyclopentadienyl manganese tri-carbonyl.

Abstract: 975,547. Flexible shaft couplings. C. W. CHAPMAN. Nov. 4, 1963 [Nov. 6, 1962], No. 42004/62. Heading F2U. A flexible shaft coupling comprises at least one pair of resilient elements connected between the driving and driven members, the ends of the elements being connected in parallel between the respective members, so that the four points of connection lie in or close to a plane containing the axis of rotation when the coupling is unloaded. In the arrangement according to Figs. 1 and 2 two semicircular spring elements S, S<SP>1 </SP>are connected to pairs of pivot-pins X, Y and X<SP>1</SP>, Y<SP>1</SP> carried by the coupling elements 1, 2 and mounted on opposite sides of the shaft axis O. In a modification, Fig. 3 (not shown), the pairs of pivots are disposed on the same side of the shaft axis. In the form shown in Fig. 4 the spring elements 20, 23 are C-shaped and the pivots include bonded rubber bushes 17, 21 and 18, 24, while stop pins 19, 25 limit angular deflection of the coupling. In a modification of this arrangement, Fig. 15 (not shown), two sets of spring elements are provided disposed at right angles to each other. In the further embodiment shown in Fig. 7 pairs of oppositely disposed semicircular connecting elements 66, 68 and 70, 72 are provided.

Title: Radio receiving systems for the recovery of data transmitted over different radio frequency carriers
IPC: H03K5/08
Filed: 1975-10-14
Abstract: 1529806 Data transmission; distortion correcting; pulse thresholding HOFFMAN ELECTRONICS CORP 14 Oct 1975 [23 Oct 1974] 42070/75 Headings H3T and H4P In an FSK arrangement where fading of the two carrier frequencies occurs differently, thresholding of the recovered base band signal at the receiver is effected with respect to a reference voltage 31B automatically set midway between positive and negative peaks determined and stored by resettable detectors 33, 35 and applied to a summing amplifier 39, each stored positive/negative value being erased following the appropriate negative/ positive transition before the next signal peak is received on terminal 29. The erase circuit comprises non-resettable monostable circuits (fed from output 31C) 45 through delay 49 and 46 through delay 47 and inverter 48. The delays 47, 49=2 millisec + monostable delay = 2 millisec: a delay of 4 millisec corrects for relative time shift in input wave peak on fading. A guard circuit comprising an R.S. flip-flop 70 prevents the monostables being operated twice in rapid succession which prevents incorrect erasure of detectors 33, 35 due to fortuitous noise pulses after the 4 millisec interval. To allow say monostable 45 to fire there must be a negative going pulse at terminal 45A plus a "high" signal from 70, and similarly with 46. Suitable circuit arrangements are given in greater detail in Fig. 4 (not shown). Output may be taken via a LED (32C) and amplifier (32D) to a printer. The audio frequency modulated multicarrier single side band input is passed through a conventional receiver 10 through mark and space band pass filters 14, 15 and full wave detector circuits 18, 19 to a subtractor 23 providing a bipolar base band signal through low pass filter 27 to terminal 29.

IPC: H01H35/26
Filed: 1959-12-14
Abstract: 879,079. Thermal switches. RANCO Inc. Dec. 14, 1959, No. 42377/59. Class 38 (5). A control device for a refrigerator comprises manually operable means for temporarily altering one limit of the normal temperature cycle to a predetermined value outside this range irrespective of the adjustment of the normal limits, for defrosting or quick-freeze, whereafter the normal cycle is restored. The embodiment described is arranged for defrosting. A temperature-responsive capsule 12 operates a snap-action switch 15 through a lever 16 pivoted at 17 and loaded by a spring 33 whose tension is adjustable by a knob 38 which controls a cam 37 acting on the lever 36, also pivoted at 17. The defrosting means comprises a lever 40 pivoted at 41 and coupled to a push knob 43 by a rod 42 passing loosely through a bore in the knob 38. The lever 40 is thus movable by knob 43 to bring an arm 44 thereon into engagement with a stop 45 or with a screw 46 on an extension of lever 16. Opposed springs 50 and 53 act on lever 40, the spring 50 being stronger than spring 53, but so attached that its centre-line moves close to the pivot 41 when arm 44 engages stop 45 thereby reducing its effective bias so that lever 40 tends to be maintained in the position to which it has been moved. Thus after knob 43 has been depressed, the arm 16 is acted on by an additional force due to springs 50 and 53, and a higher temperature has to be attained before switch 15 is reclosed, whereafter arm 44 rests against stop 45 and normal cycling ensues. The spring 53 is anchored to the lever 36 such that its tension is varied with adjustment of spring 33 and by suitable choice of springs the defrosting temperature is independent of the setting of knob 38.

Abstract: 1358378 Article counter KIRBY LESTER ELECTRONICS Ltd 2 Sept 1971 [8 Sept 1970] 42867/70 Heading G4D [Also in Division G1] Articles such as tablets, pills or capsules are fed to an inlet passage containing tapered rings 3 creating an even flow of articles and fall onto a core 5 to be distributed into separate chambers formed in an annulus 6 between a core support and a chamber 1. Each chamber is provided with a photo-cell 9 responsive to light from a central source 10 to detect each article. Data from the photo-cells is fed to transistor detectors and via a NOR gate 21 to a counter 22 feeding a decoder and display tubes. To prevent the lamps from being obscured by dust the voltage from a cell is compared with a reference voltage and if too high a discrepancy occurs, a clamp holds line 20 at zero and via a latch 26 operates a warning lamp 27. To indicate an excessive counting rate an oscillator 28 feeds a counter 31 via a pulse sharpener 29 and a gate 30. When a predetermined count is reached gate 30 is inhibited and a gate 35 is inhibited. A gate 33 is coupled to counter 22 to prouce a signal on the occurence of particular count values, e.g. 18, 38, 58 &c. and if one of these values occurs before counter 31 reaches its predetermined value a bi-stable 36 is set to activate an overspeed indicator 37 and inhibit further counting. To ensure that all photo-cells are working when a reset button 38 is pressed and released a pulse is fed to a transistor switch 41 which reduces power to the lamp 10 to simulate an article. The pulses from the photocells are counted and a gate 43 is enabled if the count is correct. The pulse from button 39 is sharpened and delayed and fed to gate 44. If the count is incorrect a fail signal is produced and fed to gate 39 to cause the operation to repeat until a correct count is achieved.
