Title: Improved means for the absorption or damping of vibration in springs
IPC: B60G15/04
Filed: 1924-12-31
Abstract: 249,242. Lander, C. Dec. 31, 1924. Vibration-dampers of the plate or disc type are applied externally to the shackles of laminated springs. In the construction shown in Fig. 1, rotation of the shackle 15, 16 about the pivotal connection 23 to the frame is resisted bv an arm 18 faced with frictional material and pressed by a spring 21 between the presser plate 19 and the shackle link 15. The arm 18 and the plate 19 are connected respectively with the frame and the shackle; or the plate 19 may be actuated by engaging the head of the lower shackle pin. In modifications of this construction, the damper is applied to the spring pivotal connection, the arm 18 being in one case anchored to the spring and in the other case connected by a link to the frame. In a further modification, the damper is mounted upon an extnsion piece which screws into the lubricating hole in the shackle pivot, the lubricator being screwed into the outer end of this extension. A similar extension piece for the lower pivot pin forms an anchorage for the presser plate. In the construction shown in Fig. 4, one of the combined shackle links and pins is replaced by a pin 57 and extended link 50, the outer face of which forms one friction member. The arm 52 is connected to the axle 60 and is clamped between the link 50 and the presser plate 51 by a spring 55. In other constructions, the plates between which the arm is clamped may be extnded on each side to carry spring clamping devices in place of the central clamping spring. In the construction shown in Fig. 12, an extension of the shackle 138 is clamped between the frame and a presser plate 140 tightened by bolts 142. A number of discs alternately splined to a fixed member and to a movable shackle member may be employed, the spring pressure being obtained from a series of Belleville washers. Fig. 13 shows a sheet metal alternative 147, 148 to the link 50 of the construction shown in Fig. 4. Alternative holes 153-155 enable the attachment to be mounted in different positions upon a vehicle. Several alternative attachments for mounting the damper on a shackle are shown. In the construction shown in Fig. 18, the pressure between the friction members is varied as the vehicle spring flexes by means of a screw 188. The screw may be replaced by cams. Conical friction members may be employed.

Title: Improvements in or relating to apparatus for polishing or cleaning floors or other surfaces
IPC: A47L13/314
Filed: 1933-11-10
Abstract: 428,086. Brushes. HISCOCK, W. L., Penmill, Fernbank Road, Ascot, Berkshire. Nov. 10, 1933, No. 31316. [Class 19] A floor waxing and polishing device of the type shown is characterized in that the stepby-step operative movement of the wax ejecting disc h, Fig. 1, is effected by a slidable frame o, Fig. 2, or a pivoted frame n, Fig. 3, intermittently driven by a pivoted handle r. The frame o operates a spring pawl n to engage a ratchet k on a threaded member j. This member drives a threaded disc h to force wax through a screen g<3>, Fig. 1. A bead f<3> prevents rotation of the disc h. The wax is supported by a detachable ring member g. The ratchet wheel k and rod j may be rotated in a reverse direction by hand to retract the disc h. The frame o slides in bearings p, p<1>, Fig. 2, and is retracted by springs q, ql. A spring pawl t rides on the teeth of the ratchet k acting as a brake and effecting one-way movement of the ratchet. In Fig. 3 the lever n acts as a pawl.

Title: Improvements relating to record-card controlled statistical machines
Filed: 1928-10-29
Abstract: 299,719. Tauschek, G. Oct. 28, 1927, [Convention date]. Statistical apparatus; multiplying and dividing, means for. - A record-card-controlled statistical machine is adapted to calculate according to the four rules. The invention is illustrated for multipilcation by repeated addition, the card 1 having two perforation fields for the multiplicand (say 314) and for the multiplier (say 205). The cards are read by sensing pins 2 arranged in two groups 9 and 10 and reciprocated vertically by frame 3 and links 4 so that pins not entering a. card hole are raised by the card and notches 8 in them are locked by bar 7. In each card column the digit is represented by a number of holes equal to the number of the digit. The first pin corresponds to the " O " position. Racks 11 coact with the pins and with adding wheels 12, so that when a rack moves to the left, Fig. 2, it rotates the wheel 12 according to the number in that card column. The racks 11 may be engaged with the wheels 12 in the forward or backward movement, thus adapting the machine for the four rules. The multiplier pins 10 coact with members 13 the ends 14 of which are U-shaped and fit into each other so that the members 13 and the sensing pins co-operate in opposite order. These members 13 also coact with members 31 which, if the corresponding member 13 move to the left, are passed by springs 21 into the path of a hook 15 on the frame 17 carrying the devices 11, 12. For a multiplier of, say, 205, the first member 13<a> coacts with the sensing pins 10 by passing over two pins to move up to the third pin, i.e. three steps to the left, the second member 13<b> is not moved, and the third member 13<c> is moved six steps. Hence the members 31<a> and 31<c> are in the path of the hook 15. A bar 23 engaging the racks 11 is reciprocated longitudinally of the racks 11. At each stroke to the left the racks 11 are moved by springs 24 and the multiplicand number 314 is added to the wheels 12; and at each return stroke to the right a pawl 26 is lifted out of the path of the member 13, which is then moved one tooth to the right by a rod 27 driven from the main shaft of the machine and a pawl 18 on a pin on the carriage. This is repeated so that after two operations the member 31<a> is removed and the hook 15 moves up to the member 31<c>, where a similar operation is repeated five times with the racks 11 moved two denominations to the right relatively to the adding wheels. In a modification, Fig. 4, the racks 11 of the previous construction are replaced by wheels 30 having; stepped teeth for coaction with the counters.

Title: Improvements in locating systems for use with semiconductor devices
IPC: H01L21/66
Filed: 1955-11-02
Abstract: 808,569. Semi-conductors testing. GENERAL ELECTRIC CO. Nov. 2, 1955 [Nov. 9, 1954], No. 31381/55. Class 37. A method of locating a thin zone of one conductivity type semi-conductor material sandwiched between two zones of the opposite type comprises applying signals of opposite phase but the same frequency to said two zones, placing a probe in sliding contact with the zones so that the phase of the signal it picks up depends on which of the two zones it contacts, and applying this signal to motive means adapted to drive the probe towards the one zone in response thereto. As shown, the ends of the secondary winding 20 the centre tap of which is earthed are connected to N-type zones 3 and 4. The probe output is amplified by triodes 26, 38, 50 and push-pull output stage 59, 61 and fed via transformer 71 to the control winding 72 of two-phase motor 13. The amplifying circuit is such that the voltage fed to winding 72 leads or lags behind the voltage applied to the other winding 73 by #/2 so that the motor moves the probe towards the middle zone. When the probe contacts this zone an unsmoothed full-wave rectified voltage is picked up and winding 72 is fed with a signal at twice the normal frequency, thereby rendering the motor inoperative. To avoid hunting by the probe a speed dependent signal opposite in phase to, but smaller than, the probe signal is produced in one winding 46 of a generator driven by the motor and injected into the amplifier via the cathode resistor 43 common to valves 38, 39. A circuit for indicating when the probe is in contact with the P-type zone 2 is shown at 77. When the probe contacts zone 3 or 4, valve 78 conducts and valve 84 is cut-off because of its high cathode voltage. A negative potential from the probe cuts off valve 78 and hence renders valve 84 conducting when it contacts zone 2, causing relay 92 to close the circuit of indicator lamp 96.

Title: Colour television receiver synchronizing apparatus
IPC: H04N9/455
Filed: 1952-12-11
Abstract: 712,738. Colour television. RADIO CORPORATION OF AMERICA. Dec. 11, 1952 [Jan. 5, 1952], No. 31425/52. Class 40 (3). [Also in Group XXXV] In a consequential colour television receiver, the local sub-carrier demodulating oscillator is synchronized with the colour "bursts" carried on the horizontal back porches by means of a control voltage derived by comparing the outputs of two of the normal phase detectors during receipt of the bursts. Thus, as shown in Fig. 2, vector 31 may represent the phase of the "bursts" and vectors 32 and 33 the correct phases of the local sub-carrier demodulating signals applied to two of the phase detectors. Under these conditions, the two detectors produce equal output vo'tages 34. Should the demodulating oscillator drift in phase, however, as indicated at 32' and 33' the two ouputs differ and a detector responsive to the outputs develops a potential proportional to their difference and controls a reactance tube operating on the oscillator to restore the correct phase relationship. In a system where the phases of the demodulating signals are not symmetrical as illustrated in Fig. 2, the two outputs will not be equal under correct operating conditions and the detector is arranged to produce an output in response to departure from the correct ratio of outputs. Fig. 4 shows the detailed circuits of the invention. The outputs of the two phase detectors are applied respectively through stages 44, 45 to two gate stages 41, 42. The gates have a common cathode network including a potentiometer 43 by means of which their relative gains may be adjusted to permit inputs in a predetermined ratio to produce equal outputs. The gates are normally biased to cut off and are rendered operative by cathode pulses applied during reception of the synchronizing "bursts" from a circuit 48-52 which receives the horizontal synchronizing pulses 52' and differentiates and limits them to produce wave 54. As an alternative, the flyback pulses from the horizontal sweep circuit may be employed to open the gates. The gate outputs are derived from the anodes and applied to a detector circuit comprising diodes 56 and 57 which produces a potential across condensers 61 and 62 proportional to the difference of the gate outputs. This potential is then applied to a reactance tube controlling the frequency of the demodulating oscillator.

Filed: 1936-11-17
Abstract: 472,784. Machine gun magazines. OSTMAN, O. A., and O/Y TIKKAKOSKI AKTIEBOLAG. Nov. 17, 1936, No. 31465. [Class 92 (ii)] The magazine comprises a cylindrical container 1, a drum or rotor 2 mounted to rotate within said container and formed with two concentric channels 3, 4 adapted to receive cartridges, and a spring 7 adapted to rotate the drum through approximately one revolution to deliver the cartridges from the outer channel 3 and then while the drum remains stationary to a drive follower 11 through approximately another revolution to push the cartridges out of the inner channel 4. The partitions 2a, 2b of the drum are bent outwardly to form an outlet for the inner channel. The cartridges are ejected from the magazine and through the outlet 37 by a fork-shaped ejector 29. The side of the magazine is closed by a cover 1b, on which is a latch 1d pivoted at 1c and adapted to be swung in under the head 9 of a central spring bolt 23 and under the head of a stop pin 1e. The spring bolt is feathered to the central shaft 5 to which one end of the spring 7 is attached. When the latch is swung out and the cover removed, ratchet cogs 23a on the inner surface of the head 9 of the spring bolt are brought into engagement with corresponding holes in a disc 12 formed with finger grips 12a by means of which the spring 7 of the drum can be wound up, after which the cartridges can be inserted. The cover 1b can then be replaced, and the spring bolt pushed out through a central hole in the cover to allow the inward swing of the latch 1d. A stud 36 on the latch then engages the cogs on the head of the spring bolt.

Abstract: 767,427. Conductor arrangements; earthing arrangements. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 2, 1954 [Nov. 9, 1953], No. 31613/54. Class 38 (4). In a polyphase transmission system 1 having an earthed neutral and provided with means for high-speed reclosing of circuit breakers 2R-2T, 3R-3T in faulty phases, reactors L1, L2 are arranged on the line side of the circuit breakers and are of such inductance values as to compensate the phase-to-phase and phase-to-earth capacitances C1, C2, respectively, of the system to a degree such that an arc 5 formed between a faulty phase, say T, and earth and fed by coupling from sound phases, say R, S, can extinguish. The reactors may be assembled in groups, the individual inductances of which are so coupled that the zero-sequence reactance of a group is higher than its positive-sequence reactance. Thus, a group may comprise individual phase reactors L1 connected in star and earthed through a common reactor L2. Alternatively, the star point may be directly earthed and the reactors provided with secondary windings which are connected in parallel, there being no reactor L2; or each reactor of the group may comprise two windings, which coact for zero-sequence currents and oppose each other for positivesequence currents. The arrangement may be such that the reactors are only in service when the system is lightly loaded or affected by a fault, for which purpose they may be connected to the system through circuit breakers operated in dependence on the condition of the system; or the effective inductance of the reactors may be varied by control windings responsive to the condition of the system.

Abstract: <PICT:1099637/C1/1> In a process for growing silicon carbide epitaxially, P-type silicon carbide crystals 4 are disposed at an angle to the horizontal in a sealed graphite vessel 1 containing lumps of silicon 6.  A temperature difference is maintained between the top and bottom of the vessel by locating it in an eddy current heating coil or passing current through its walls by mounting between electrodes within a graphite shield in a water-cooled container (Fig. 2, not shown).  The silicon melts (submerging the substrate crystals) and reacts with the graphite vessel to produce silicon carbide which is slightly soluble in the silicon. The carbide grows epitaxially on the cooler substrate crystals as N-type material due either to excess silicon or nitrogen included in the graphite.
