Title: A device for automatically locking a belt or the like
IPC: B60R22/415
Filed: 1964-09-11
Abstract: 1,086,514. Safety harnesses. H. I. R. KARLSSON. Sept. 11, 1964 [Sept. 13, 1963], No. 37371/64. Heading A3V. A retractable safety belt is arrested at a predetermined rate of withdrawal of the belt by the displacement of an inertia nut on a threaded end of a spindle. The belt spindle 15 has a threaded end portion 16 which carries the inertia nut 17 which rotates with the spindle. A cylindrical housing 10 supporting the spindle also supports a pendulum 31 which, when the vehicle decelerates, swings to bring an end portion 32 of the pendulum into engagement with teeth 28 on the upper surface of the nut 17 thus arresting the nut. The continual rotation of the spindle causes movement of the nut along the threaded portion overriding the portion 32 and bringing the teeth 28 into mesh with teeth 29 on the end cap 11 of the housing. The spindle is thereby arrested and the belt cannot be withdrawn. Manual control of the pendulum is provided by an arm 35 pivoting on the pendulum pivot and having an arcuate member 36 which can be moved to hold the pendulum in an active or inactive position. In the latter position the nut is displaceable by its inertia. A Bowden cable may control the arm remotely. In a modification the nut engages the spindle with play so that on deceleration of the vehicle the nut is arrested by engaging the side of the housing 10 which has a pivoted lever which engages teeth on the periphery of the nut. In another modification when the vehicle decelerates a sliding member overcomes the action of a spring to move it to engage teeth on the periphery of the nut.

Title: Absence signal device for telephone
IPC: H04M1/65
Filed: 1958-11-20
Abstract: 904,658. Substation equipment. MURAMATSU, H. Nov. 20, 1958 [Nov. 21, 1957], No. 37446/58. Class 40 (4). A switch 1 may be set to connect the incoming line A either to the normal telephone apparatus B or to an oscillator 14 which is normally biased to an inoperative position; when the line is connected to the oscillator, the reversal of potential on the arrival of an incoming call causes current to flow through the halfwave rectifier REC so that the oscillator 14 generates a signal which is transmitted over the line A to the calling subscriber as an indication of the absence of the called subscriber. In modifications. Figs. 5-7 (not shown), the oscillator operates only in the intervals in the intermittent calling signal.

Title: Electric circuits including transistors
IPC: H03K3/286
Filed: 1954-12-29
Abstract: 785,839. Transistor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 29, 1954 [Dec. 31, 1953; Dec. 31, 1953], No. 37539/54. Class 40 (6). In a transistor circuit the collector load impedance includes an asymmetrical unit, a resistor and bias supply so that the load impedance has at least two different values in corresponding collector current ranges. By this means effects due to hole storage at the time a transistor is turned off are minimized. The load 5, Fig. 1, is operative to give the load line 12, Fig. 2, until the collector potential exceeds that of battery 8, whereupon diode 7 becomes effective to give the load line 13. By suitable choice of diode 7 and battery 8 the composite load line 12, 13 may approximate to the curve 11 formed by joining the circles. The resistor 2 may be transferred to the base lead, Fig. 6 (not shown), and an earthed base circuit may be employed, Fig. 8 (not shown). In a modification, Fig. 4, the collector load is in the form of a transistor 22, its negative impedance being utilized to give the curve 29, Fig. 5, which coincides with a line of constant emitter current. For low values of current through transistor 1 and resistor 23, the transistor 22 is effectively biased off at the emitter. With increasing current the base potential falls until the emitter passes current and amplification occurs, continuing until saturation is reached.

Filed: 1959-11-07
Abstract: A process for the production of a rigid polyurethane foam comprises reacting an alkoxylated novolak resin with a polyisocyanate and water in the presence of a polyurethane-forming catalyst.  By an alkoxylated novolak resin is meant a novolak resin in which at least one phenolic group per molecule has been etherified by reaction with an a ,b -alkylene oxide.  The novolak can be derived from such phenols as phenol itself, cresols, difunctional xylenols, resorcinol and diphenylol propane, and from formaldehyde, acetaldehyde and benzaldehyde. 1,2-Ethylene-, propylene- and butylene oxides are specified alkylene oxides. They may be reacted with the novolak or with the phenol before reaction with the aldehyde is effected. Catalysts for the foam formation include triethylamine and triethylene diamine.  In examples (1) an ethoxylated novolak is prepared by reacting (with a hydrochloric acid catalyst) formaldehyde and an ethoxylated phenol (from phenol and 5,2 moles of ethylene oxide).  Ethyl cellulose and wetting agent are then dissolved in heated novolak and, after cooling, foaming is effected by adding zinc naphthenate in white spirit, aqueous triethylene diamine and a commercial tolylene diisocyanate mixture.  Sufficient heat is generated to cure the foam.  (6) A similar process is carried out using a novolak obtained from an addition product of 7,7 moles of ethylene oxide with 1 mole of resorcinol.

Filed: 1957-12-06
Abstract: The invention comprises compounds of the general formula: <FORM:0812120/IV (b)/1> where n=6 or 7, R1 and R11 represent H, alkyl, cycloalkyl or aryl, and R1 and R11 may also be part of a common ring, in which an oxygen atom may be present.  The compounds may be prepared by reacting cycloheptylamine or cyclo-octylamine with phosgene and reacting the isocyanate so formed with a primary or secondary amine.  The hydrochlorides of cycloheptylamine and cyclo-octylamine may be used as starting materials and reacted with phosgene in an inert solvent such as dry benzene, toluene, xylene, dioxane, cyclohexane, phenolethers and ethyl acetate, preferably above 50 DEG  C.  Suitable amines for the second stage of the reaction which may be carried out at 0-100 DEG  C. in the same solvents, are methyl, ethyl, butyl, dimethyl, diethyl, methylbutyl, dicyclohexyl-amine, methylaniline, pyrrolidine, piperidine or morpholine.  Alternatively, carbamic acid chlorides prepared from secondary amines and phosgene may be reacted with cycloheptyl or cyclooctylamines, using solvents as before, and an acid acceptor such as pyridine, trimethylamine, dialkylaniline, or quinoline.  Excess of the amine may be present in this case.  The compounds of the invention may also be prepared by consecutively replacing the two NH2 groups of urea by substituted amines.  The first stage of the reaction takes place in aqueous hydrochloric acid solution at temperatures above 75 DEG  C., and after separation of the monosubstituted urea by filtration, by suction from the ammonium chloride solution, the reaction continued above 150 DEG  C., preferably in the presence of e.g. nitrobenzene, dichlorobenzene or phenol ethers.

Abstract: 619,822. Vehicle suspensions. FORD MOTOR CO., Ltd. Dec. 30, 1946, No. 38051. Convention date, Jan. 21, 1946. [Class 108 (ii)] A vehicle suspension comprising a supporting member 17 pivoted about a longitudinal, horizontal axis 19 and a torsion spring 25 connecting said member to the vehicle frame, is characterised in that at those points at which the torsion spring moves angularly relatively both to the supporting member and to the frame, an anti-friction bearing is interposed between the torsion spring and the supporting member and frame respectively. The torsion spring, which, as shown in Fig. 3, is in the form of a bar 25, is at its front end 31 bent to a U-shape, of which one arm passes through a sleeve 26 in the supporting arm 17. A halfcylinder 29, Fig. 4, of anti-friction material is placed between the torsion bar 25 and a halfcylindrical shell 28 secured in the upper half of the bush 26. The anti-friction material, which may be metallic or non-metallic and of the lubricated or non-lubricated type, is secured either to the bar 25 or to the shell 28. The rear end of the bar is bent reversely to a U- shape, of which one arm is located by a groove 34, Fig. 5, formed in the lower flange 33 of the vehicle frame member 14, while the other arm 36 rests on shims 39 secured to the flange 37 of a channel section 38 which is secured in the frame member 14. The shims 39 allow adjustment of the riding height of the vehicle. A half-shell 35 of anti-friction material is placed between the bar 24 and the groove 34 and may be secured either to the bar or to the groove. In a modification, Fig. 6, the wheel suspension arm 53 has an integral sleeve 52, carrying a oush 54 containing an anti-friction bearing 55 for the bar 51, while caps 56 retain any lubricant; to simplify the construction, a half-shell of antifriction material may be bonded to the torsion bar and allowed to engage the integral sleeve directly.

Abstract: 883,897. Electronic counting-apparatus. GENERAL ELECTRIC CO. Ltd. Nov. 19, 1959 [Nov. 28, 1958], No. 38459/58. Class 106 (1). [Also in Group XL (c)] In a binary counter comprising a plurality of cross-coupled bi-stable transistor stages, the input pulses are supplied to all the stages via gates, each gate being controlled by the stages of lower order. As described, a binary counter comprises four stages 2-5 each comprising a pair of P-N-P junction transistors such as 6, 7, cross-coupled in known manner to form a bi-stable circuit. Input pulses to be counted are supplied from a source 1 via a transformer 16 to the first stage via a line 8 and to subsequent stages via a line 19. A " 0 " is represented in each stage by the right-hand transistor thereof being in a conducting state. In each stage there are provided gates 9, 10 arranged so that each pulse applied to the stage causes it to change to its other stable state. Gating devices 20-22 are provided for gating pulses to the three higher stages. The gating device 20 comprises a transformer 26 which passes a pulse to the associated stage 3 only when a transistor 28 is biased to be conducting. The transistor 28 is controlled through diodes 35, 36 such that when the transistor 7 of the first stage is conducting, the transistor 28 is maintained cut off, but when the transistor 7 is cut off, the transistor 28 is maintained conducting. Transistors 33, 34 are provided as emitterfollowers. The gating device 21 is controlled through diodes 42, 43 to pass a pulse to the stage 4 only when the stages 3 and 2 register a " I." The gating device 22 is similarly controlled by a diode gate 46. A network 37 is provided to reduce the voltage swing applied to the base of the emitter-follower transistor 34. Additional binary counting stages may be provided if required. The circuit may be adapted as a binary-coded decimal counter by changing over switches 39, 59 and 60, a gate 63 being opened when the stages 2 and 5 both store a " 1 " (i.e. 9 pulses have been counted), an emitter-follower 64 thereby producing an output pulse between the ninth and tenth input pulses. The gating device 22 is conditioned to pass the tenth pulse to the stage 5, thus zeroizing the circuit. A second decade state may be provided (Fig. 2, not shown). Outputs from the bi-stable stages may be arranged to give an output signal when a predetermined count is reached.
