Abstract: 657,884. Feeding sheets &c. HALL TELEPHONE ACCESSORIES, Ltd., and HARRINGTON, P. T. R. March 29, 1949, No. 8497. [Class 100 (i)] In a machine, such as for opening envelopes, stamp-affixing, or sheettrimming, wherein the envelopes or sheets 6 are fed singly past a fixed station by a travelling conveyer 20 against which the envelope is pressed resiliently by a shoe member 23, the latter is mounted on a scissors lever arrangement 29, 30, and connected to one lever 29 by a pin-and-slot connection 32 and to the other lever 30 by a pivot 28. The levers 29, 30 are hinged about a fixed pivot 31, their lower ends are urged together by a spring 33, and their upper ends are bent over and provided with adjustable bolts 36, 37 which support a cross-plate 42 and bear against lugs formed on a fixed plate 44. A top hood 4 of the machine is provided with a button 51 which can be depressed against the action of a spring to engage the plate 42 to cause the lower ends of the levers 29, 30 to rise, thereby lifting the shoe 23 at opposite ends by equal amounts. In the envelope-opening machine shown, the casing 1 is provided with hand-recesses 8, 9, and is partly covered by a plate 2, and by the hood 4 which has an envelope inlet 5 and outlet 7 therein. An electric motor 10 is adapted to drive, through belt-and-pulley means, a shaft 16 having a pulley 19 thereon connected by the conveyer belt 20 to a further pulley 21. The envelope-conveyer belt 20 projects slightly above the cover-plate 2, constituting a feed table, and, viewed from above, is inclined towards a side guide 22<SP>1</SP> (not shown) so that the envelopes 6 are urged and registered against this guide by the belt. To assist in feeding and separating the envelopes, the table 2 is provided near the inlet 5 with a projecting portion 53 (not shown) which slopes downwardly towards the side guide 22<SP>1</SP> and also in the direction of travel of the envelopes. Instead of a belt 20, the travelling conveyer may comprise an inclined disc projecting through the table 2.

Title: Low tension ignition system
Inventor: DILGER LEROY EDWARD
IPC: F02P3/08
Filed: 1958-03-18
Abstract: 852,414. Ignition systems. GLOBE-UNION Inc. March 18, 1958, No. 8703/58. Class 7(4). [Also in Group XXXV] An electrical low tension ignition system using a creepage gap sparking plug and a source of unidirectional pulsating voltage, includes a first capacitor continuously connected to the source of unidirectional pulsating voltage and a second capacitor the capacitance rating of which is not greater than that of the first capacitor alternately connected in parallel with the first capacitor and the plug. As shown in Fig. 1, a unidirectional pulsating voltage is applied to a storage capacitor 14. The charging breaker points 16 are first closed and then opened to charge the sparking capacitor 12 from the storage capacitor before a distribution breaker point is closed. After the distributer breaker point is closed the discharge breaker points 18 are closed and opened to fire the plug and then the distributer points are opened and the cycle repeated for the next cylinder. In the drawing the single lobe cam and angularly related breaker points are diagrammatically shown as two connected cams 20, 22 to operate the breaker points 16, 18. Fully closing breaker points are employed for charging, discharging and distribution. As shown, the unidirectional pulsating voltage applied to the capacitor 14 is obtained by means of an oscillatory circuit employing a pair of transistors 34 and the associated transformer and rectifier circuit shown. In a modification the oscillatory circuit is replaced by an interrupter type vibrator. In Fig. 3 the single capacitor 14 is replaced by a pair of capacitors 14a, 14b and the transformer primary 52 is directly connected to an alternating current source. If the frequency of the alternate polarity voltage fed to the rectifier is less than the frequency of discharge of the sparking capacitor then the capacity of such storage capacitor must be proportionately greater than that of the sparking capacitor to maintain a voltage level on the storage capacitor which is high enough to charge the sparking capacitor to its operating level.

Title: Television receiver with interference suppression for picture and sound
IPC: H03G11/00
Filed: 1959-03-13
Abstract: 877,126. Limiting circuits. STANDARD TELEPHONES & CABLES Ltd. March 13, 1959 [March 15, 1958], No. 8810/59. Class 40(6) In a television receiver for a system employing positive picture modulation and amplitude modulated sound the noise limiter for the sound channel is of variable time-constant. The sound detector 1 feeds series diode limiter Dl via blocking condenser C1 ; the diode is biased conductive from a positive source via resistor R1 and feeds into resistor R2 from which the audio signal is obtained via blocking condenser C2 and volume control potentiometer R3. The arrangement is of the type in which resistor R2 is shunted by a condenser, the time-constant being such that the voltage across R2 "follows" the signal applied to the diode D1, except for noise pulses for which the time-constant is too long and the diode cuts off. According to the invention the time-constant is made variable, either as shown by switching in alternative condenser C 3,1  and C 3,2  of different value or by using a variable condenser or a condenser in series with a variable resistor, so that when noise is excessive the time-constant can be increased, even though higher frequencies are thereby lost. The switch 1 may be mechanically coupled with a switch introducing a noise limiter into the video channel.

Title: Driving circuits for driving moveable elements particularly for motors or timepieces
Inventor: NEMOTO K
IPC: G04C3/06
Filed: 1970-02-24
Abstract: 1,274,126. Transistor oscillators. HATTORI TOKEITEN K.K. 24 Feb., 1970 [28 March, 1969], No. 8880/70. Heading -H3T. [Also in Division G3] A self-starting oscillator circuit for driving a moving element of a timepiece-e.g. a balance wheel 1 (Figs. 1 and 2) or a vibratory arm (Fig. 4, not shown) or a ferrite disc rotor of a motor (Fig. 5, not shown)-comprises an astable multivibrator having a coil L as a load and which functions both as a drive and pick up coil. To effect starting the width of a drive pulse is greater than when steady state conditions are reached. As shown, Fig. 2, a ring coil L is coupled electromagnetically to a balance wheel disc 3 on a shaft 2 and carrying a permanent magnet 4 and counterbalance mass 5. In operation, with wheel 1 (Fig. 1) stationary and a switch S closed, a capacitor C is charged to a voltage Al (Fig. 3a) from a source E via coil L, R 1  and S. When C is charged Tr 1  turns ON. C then begins -to discharge through a loop comprising the base/emitter of Tr 2 , Tr 1 , C and Tr 2  turns ON so that C also discharges through a loop-Tr 2 , R 1  and C. As long as Tr 2  is ON a current pulse e 0  (Fig. 3c) flows in coil L and drives-wheel 1. When C is discharged Tr 1 , Tr 2  turn OFF. C thus begins to charge again and the cycle is repeated .Movement of wheel 1 magnet induces a voltage [in L. Thus a waveform b 1  (Fig. 3b) is applied to the base/emitter circuit of Tr 1 , i.e. a waveform as b 0  with the induced voltage superimposed. At this time C is charged with waveform a 2  to a voltage A 3  and Tr 1  is turned ON. Tr 2  -is switched ON by the discharge of C and a drive pulse e 2  is applied to coil L. The amplitude of oscillation of wheel 1 gradually increases and the induced voltage also rises and is applied to Tr 1  -base/emitter thus increasing the frequency at which Tr1 is turned ON. The charge and discharge periods of C are shortened also the drive pulse widths are steadily narrowed until a steady state vibration of the balance wheel 1 is reached. The drive pulse widths and frequency stabilize and synchronize with the natural frequency of the balance wheel 1. Modified oscillator circuits 4, 5, 6 (not shown) operate similarly. Their operation is not described. In the Fig. 4 embodiment a thermistor is provided for temperature compensation.

Title: Improvements in metal fencing
IPC: E04H17/04
Filed: 1934-03-24
Abstract: 435,202. Fencing ; wire fabrics; barbed wire. WOLLASTON, H. J. BUCHANAN-, The Pantiles, Pakefield, Lowestoft. March 24, 1934, Nos. 9241, 11135, and 27329. [Class 45] A wire fence made of single lengths of wire linked together, each extending from top to bottom of the fence, is formed with rectang u 1 a r meshes with their sides vertical and horizontal, the horizontal sides of adjacent meshes being in line and the wire of such thickness and hardness that the fence will support great horizontal strain without deformation of the linked wires which are formed with interengaging bights bent or offset so that the general surface of the fence is flat. The wire may be of spring steel, " stainless " steel, phosphor bronze, or nickel silver. The upper ends of the wires may project at any angle or be bent into decorative form, and the lower ends may be bent and embedded in the ground or in concrete. Some of the wires may be thicker than others to form supports between the fence posts. As shown diagrammatically in Fig. 2, the wires are bent at a ... e to form narrow bights which are slightly offset, the bends a ... e being shown on an enlarged scale for clearness, and a suitable mesh being 12 by 2¢ inches, or in a modification, Fig. 3 (not shown), 9 to 18 inches by 2¢ inches with three meshes in each vertical row. As shown in Fig. 3A the lower bights are offset oppositely to the upper bights and linked together from the opposite side so as to hinge on one another in the opposite sense and form a more rigid fence in use, and this fence may be transported in rolls with the lower bights unlinked. In a modification, Fig. 4 (not shown), only one side of the bights c and c<1> is engaged by the adjacent wire, this form being suitable for very thick wire. As shown in Fig. 5, an unclimbable topping for walls or fences is made of looped units a, b linked together with the ends bent at rightangles. In another modification wires bent as in Fig. 6 are looped together as shown in Fig. 7. The first Provisional Specification describes a form of the wire element in which the ends are not in the same vertical line as the middle portion and the corners at the outer end of the bight are formed by bending the wire out and back in the plane of the fence in a direction at 45 degrees to the vertical.
