Abstract: 763,162. Locks. POEL, F. C. VAN DER, BESIJN, J., RUEB, E. C. W., and BLOENENDAAL, W. F. VAN, [trading as JACOBSON VAN DEN BERG & CO.]. Dec. 15, 1954 [Dec. 22, 1953], No. 36371/54. Class 44. Relates to a latch bolt lock for doors having a latch-bolt casing, a latch bolt bar traversing the casing and the latch bolt for actuating the latter by axial displacement of the latch bolt bar bearing handles at its extremities and guiding means for the latch bolt bar and the handles. According to the invention, a rotatable control element and a movable lock pin are provided within the latch bolt bar in the longitudinal and transverse directions respectively thereof, the control element and lock-pin being in co-operative relation with each other and with parts of the handles, and the lock-pin being adapted to prevent movement of the latch bolt out of its locking position and axial movement of the latch bolt bar. As shown, a latch bolt 1 is biased to the shot position by a spring 4 and includes a channel part 5 for a latch bolt bar 6 having a, square or rectangular intermediate part. An inner door handle 7 is axially and rotatably mounted on the bar 6 through a pin- and slot connection 10, 11 and an outer handle 8 is rigidly mounted on the other end of the bar 6 through a screw 15. Cover-plates 14, 18 are connected together by through-bolts 21. A control element 26 located within the latch bolt bar 6 is adapted to engage one or more blocking elements 27 for movement into or out of the bar 6. The connection between the elements 26 and 27 may be through a pin-and-slot connection 53, 54, the latch bolt 1 being formed in this region with recesses 28. The handle 7 is in driving connection with the element 26 through a pin-and-slot connection 29, 30, the rotation of the handle being limited by the pin- and-slot connection 10, 11. The handle 8 is provided with a barrel-type lock 31, having a coupling element 33 for engaging a slot 32 at that end of the element 26 and for subsequently rotating the latter to move the blocking element into or out of the blocking position with respect to the latch bolt 1. The bar 6 is provided with contact surfaces 34 which co-operate, upon axial movement of the bar 6, with surfaces 35 on the latch bolt 1 to withdraw the latter from the shot position. In another arrangement, Fig. 5 (not shown), the surfaces 35 on the latch bolt 1 are replaced by rollers or the like. In other arrangements, Figs. 6-8 (not shown), withdrawal of the latch bolt 1 is effected by rack-and-pinion gear, spring-loaded levers and rope or chain connections between the bar 6 and latch bolt 1, respectively.

Abstract: 861,588. Automatic frequency control systems; radio receiving systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Nov. 12, 1959 [Nov. 12, 1958], No. 36441/58. Class 40(5) A television receiver for a vestigial sideband transmission system comprises means for controlling the receiver local oscillator frequency and means for detecting and preventing the reversal of the incoming video signal. The received signal is squared at 15 to derive a reference oscillation of twice the carrier frequency for one input of comparator 18, the output of the local oscillator being squared at 17 to derive an oscillation of twice the oscillator frequency for the other input of frequency comparator 18, any difference being used to control the oscillator frequency. Pulses coincident with the line synchronising pulses of the received signal are derived at 19 and used to gate the output from demodulator 12, any reversal in said output causing a change in output from the gate 20 which is used to operate reversing switch 11 to alter the polarity of the received signal.

Title: Process for the manufacture of vinyl sulphuric acid and homologues thereof
IPC: C07C303/24
Filed: 1920-12-30
Abstract: Vinyl sulphuric acid and its homologues are prepared by forcing an acetylene hydrocarbon under pressure into concentrated sulphuric acid cooled to a temperature below 0 DEG  C., preferably in the presence of a catalyst such as mercury sulphate.  Alkyl ethers of vinyl alcohol and its homologues.-According to the Specification as open to inspection under Sect. 91 (3) (a) these ethers result from the interaction of an alcohol with the above-mentioned esters.  According to examples, vinyl sulphuric acid warmed with ethyl alcohol, preferably under reduced pressure, yields vinyl ethyl ether; and in a similar way, vinyl isopropyl ether and vinyl normal propyl ether can be prepared.  The intermediate isolation of the ester may be dispensed with, by adding the alcohol to cold concentrated sulphuric acid into which the acetylene hydrocarbon is forced under pressure. For example, vinyl ethyl ether can be obtained by introducing acetylene under pressure into a cold mixture of ethyl alcohol and cold concentrated sulphuric acid.  These ethers are useful for the manufacture of varnishes, artificial resins and synthetic rubber substitutes.  This subject-matter does not appear in the Specification as accepted.

Title: Commutatorless electric motor electronic commutation system
IPC: H02P6/08
Filed: 1973-08-06
Abstract: 1424208 Brushless motors ALLIS-CHALMERS CORP 6 Aug 1973 [7 Aug 1972] 37207/73 Heading H2J  A brushless motor system comprises a ferromagnetic stator provided with n-phase power windings A1P-B2P displaced 360 degrees/n apart, a ferromagnetic rotor R and n transistor power switches PSA1-PSC2 each of which is in series with one of the power windings across a power source B, a rotor position sensor 11 for sequentially turning on the power switches, and a base drive winding arrangement A1D-B2D on the stator and inductively linked to the power windings for supplying base drive to the power switches. In a preferred embodiment, each phase power winding has a centre tap and 2n, i.e. 6, transistor power switches are provided, each being connected in series with the source, battery B 1  and one of the power winding halves, corresponding halves being wound in opposite senses and the corresponding power switches each being enabled in square wave fashion in anti-phase. The base drive windings are similar in configuration and each half winding A1D-C2D is inductively linked with a corresponding one of the half drive windings and connected via the collector-emitter path of a transistor in interface circuits 1FA1-1FC2 to the bases of the several parallel connected transistors making each power switch PSA1- PSC2. Control of the power switches is effected by turning on or off the transistor in the interface circuits and a conduction period is initiated by a pulse from oscillator 20. Control of speed and torque of the motor is effected by causing conduction of the power switches at later or earlier times in each of their conduction periods. The rotor R is connected to a capacitive position sensor 11 which provides, together with square wave generator 12, a series of three-phase square waves, of a frequency indicative of motor speed. These signals are fed to and combined in an edge detector 14 which provides an evenly spaced pulse back to a comparator 17 and to a variable delay 15. The delay 15 is fed with a voltage from a speed-set potentiometer PCP and produces a pulse train, each pulse of which ends coincidentally with a pulse from detector 14 and commences at a time between two adjacent such pulses in accordance with the potentiometer setting. These pulses are passed to a gating circuit 22 together with the outputs of circuit 19 which receives inputs from means 16 which combines the data regarding desired direction of travel as set by switch 90 and data from comparator 17 as to whether the motor is rotating above or below a particular speed. A signal on one of four lines is applied at 19 together with the 3-phase output from generator 12. If the motor is rotating above the speed a 60 degree torque angle is selected and if below, a 0 degree angle is selected. Thus the timing of the marks on particular lines A1-C2 is set in means 22 by signals from means 19 and their mark time is selected by signals from delay 15.
