Abstract: 1,018,955. Safety harness. AMALGAMATED ROADSTONE CORPORATION Ltd. Dec. 3, 1963 [Sept. 20, 1962], No. 35893/62. Heading A3V. Locking means associated with a spindle on which a strap of vehicle safety harness is wound are actuated to lock the spindle against rotation by a predetermined degree of deceleration of the vehicle as opposed to acceleration of the wearer relative to the vehicle. As shown, Fig. 1, a housing 10 supports a spindle 13 spring- biased at 12 to wind in a harness strap- (not shown) and a weight 16 connected by links 18, 19 with a lever 20 rigidly secured to a pawl 21. Both the lever and the pawl are pivoted about a pin 22 fixed to the housing 10. When the weight 16 swings in a generally horizontal direction due to acceleration, deceleration or violent cornering, the lever 20 is pivoted upwards about the pin 22 moving the pawl into locking engagement with a ratchet wheel 15 rigid with the spindle 13. In an alternative embodiment, Fig. 4, not shown, in which the ratchet wheel is locked only on deceleration of the vehicle a pendulum weight 46 carries a lug 51 to which a pawl 48 is pivoted, the lower end of the pawl being pivoted to the housing 42 at 49. Movement of the weight 46 may be damped by immersion of its lower end in oil 52. In a modification (not shown) of the embodiment of Fig. 4 the weight is replaced by two vertical strips joined by a cross-member. A substantially Z-shaped pawl is pivoted at its lower free end to a link pivotally mounted on the crossmember and intermediate its ends to the housing. On acceleration or deceleration the pawl is pivoted about the last mentioned pivot into locking engagement with the ratchet wheel.

The brackets may be integral with transverse members 35. The ends of the pins may be round or flat, and may in some cases have tapered parts extending slightly beyond the pitch-line. When revoluble link-pins 32 are employed, they are confined by abutments formed by turned-over parts at one side of the links, and plates attached to the other side. The sprocket-wheels 28, 29 are splined on their shafts and are secured thereto by screws 29b. A guide 37 for maintaining engagement of the pins 36 with the perforations is formed with inclined ends, and a slot 38 for the pins.

Abstract: 1476645 Protective circuits ASEA AB 21 Aug 1974 [22 Aug 1973] 36696/74 Heading H2K A circuit for protecting pieces of electrical equipment in an electrical network comprises directional wave detectors WD associated with each piece of equipment, each wave detector comprising filters for filtering out the network frequency and at least one wave detector unit per phase for sensing current and voltage transient waves at a measuring point due to faults and being connected to a level detector N, there being a logic system A1 which receives and compares the output signals from the directional wave detectors and passes a tripping signal from any of the directional wave detectors which exceeds the level set by the level detectors only when none of these wave detectors is emitting a blocking signal which it will do or not depending on the direction of travel of the transient wave. This tripping signal operates a circuit breaker which disconnects the equipment The logic system comprises a sequence detector S which in the event of a fault ensures that only the first transient wave travelling through the measuring point is able to influence the logic system. For unipolar release of the circuit breaker in the event of a single phase fault the logic system includes a phase selector F. In the case where a line is being protected a relay unit R delays the tripping to allow any blocking signals to arrive from distant parts of the line. An additional level detector N3 having a higher level of operation may be provided with an additional sequence detector 53 to be operable when the other sequence detectors S1 are blocked. Where a wave detector is used for protection of two adjacent pieces of equipment a further level detector N2 and logic system A2 are present.

Title: Improvements in or relating to electron discharge device oscillation generators
IPC: H03B5/34
Filed: 1938-12-16
Abstract: 522,803. Valve generating circuits. FIDES GES. FUR DIE VERWALTUNG UND VERWERTUNG VON GEWERBLICHEN SCHUTZRECHTEN. Dec. 16, 1938, No. 36739. Convention date, Dec. 17, 1937. [Class 40 (v)] In a crystal-controlled multi-grid valve generator I, the control crystal Q is included in circuit between a negatively biassed grid G3 and an adjacent grid G2 on the cathode side which is positively biassed, high impedance grid leaks R1, R2, which may be resistances or complex impedances, being associated with the grids. The oscillatory circuit comprises grid G3, crystal Q, capacity Cq, which may be included for fine adjustment of the frequency, and grid G2; an increase in potential on the negative grid G3 causes a decreased current to the positive grid G2 which results in an increased potential at grid G2 which is then coupled to grid G3 through the crystal Q. The biassing potentials are such that operation occurs at the bend of the characteristic connecting voltages on grid G3 and current to grid G2 ; a regulating voltage obtained by rectifying the output may be applied to a further grid G1 to control the operating characteristic and adjust the degree of backcoupling so as to limit the oscillations to small amplitudes. The anode circuit may be tuned to produce better matching with the load, but this circuit is not a constituent part of the oscillatory. circuit and reaction 'between the anode and oscillatory circuit may be minimized by a further grid G4 maintained at cathode potential C as regards alternating current. The generator described can be used as a frequency standard of wide range by producing any desired harmonic or sub-harmonic. As shown in the Figure, the generator output is applied through R C coupling to a modulation grid G3 of an auxiliary back-coupled generator II which is approximately tuned to a desired harmonic of generator I by the switches S1, S2, which vary the back-coupling inductances L1, L2 included in the tuned grid and the anode circuit respectively. With switch S3 in position 1, the output from generator 1 is applied to generator II but with the switch in position 2 the output from generator I is earthed and additional capacities are switched in parallel with C1, the unsynchronized generator II being then used for rough measurements. When used for the frequency calibration of transmitters, the external high-frequency is applied at terminals 3, 4 and the beat frequency produced between this applied frequency and the harmonic of the quartz frequency given by generator II is detected by headphones or a galvanometer connected to terminals 5, 6 or 7, 8. For such use the auxiliary generator is operated as a super-regenerative receiver, the crystal frequency constituting the quenching frequency. A sub-harmonic of the crystal frequency can be produced by using generator I to synchronize another generator rich in harmonics, e.g., a relaxation-oscillator, one of the harmonics of this oscillator being approximately equal to the crystal frequency.
