Title: Tuned ionic oscillator
IPC: H03B7/10
Filed: 1919-08-09
Abstract: 150,516. Whiddington, R. Aug. 9, 1919. Electric oscillations, producing; thermionic relays.-A valve containing traces of gas or vapour is adjusted to oscillate with a frequency determinad by the grid potential, the dimensions of the valve, and the molecular mass and ionic charge of the contained gas. The principle of retro-action is not made use of, and tuned circuits are either not employed at all, Fig. 1, or are used only in an auxiliary sense and not for determining the frequency of oscillation. The grid potential is positive and does not generally exceed a few volts. A theory of the action of the valve is described, depending on the production of positive ions by collision, which return and bombard the filament, producing an extra flight of electrons, which produce more irons by collision, and so on. The valve may. be used either for transmitting or receiving wireless signals, its natural frequency of oscillation being adjusted in the latter case either to agree with that of the received waves or to differ slightly, so as to produce beats for heterodyne working. Specification 114,539 is referred to.

Title: Improvements relating to ventilating fans
Inventor: WILLIAMS GEORGE ARTHUR
IPC: F04D25/14
Filed: 1951-08-28
Abstract: 720,542. Screw fans. HOTPOINT ELECTRIC APPLIANCE CO., Ltd. Aug. 8, 1952 [Aug. 28, 1951], No. 20266/51. Class 110 (1). In an electrically driven fan of the kind which is used in an aperture of a wall or window, the aperture can be closed by pivoted blades which are moved from the closed to the open position and vice versa in response to, or simultaneously with, the operation of the switch of the driving motor. The frame 1 of the fan is mounted, by means of rings 3, 4 and gaskets 5, within a hole in a window or other panel 2 and has a rectangular exhaust opening 10 which is closable by means of pivoted louvres 11 which overlap in the closed position. The louvres have arms 12 which are interconnected by links 13 and 13<SP>1</SP> for simultaneous actuation. Two of the louvres carry cranks 14 and 15 respectively, which are connected by a link 16 to form a toggle. A tension spring (not shown) is connected between the spindle 27 and the common pivot 17 of crank 15 and link 16. In the closed position of the louvres and in the open position shown, the toggle is over the dead centre position, so that in each case the spring holds the louvres in position. An abutment 141 limits the movement of the toggle. The fan is controlled by cords 19, 21 which are wound in opposite directions around a pair of pulleys mounted on the shaft of the rotary switch 25 of the driving motor 6. Thus, pulling cord 21 opens the louvres and switches on the motor, while pulling cord 19 closes the louvres and switches off the motor. The opening of the louvres may be effected by an electromagnetic relay, the winding of which is connected in series or in parallel with the motor 6 so as to be energized when the motor is switched on. The louvres may be replaced by an iris diaphragm comprising arcuate blades attached to relatively rotatable concentric rings. One of the rings is attached to the frame 1, preferably between the fan blades 9 and the spider 7 which supports the motor 6, so that the blades bear in the closed position on the casing of the motor In addition there may be fixed blades across the opening 10 to deflect rain.

[Class 146 (iii)] In a fountain pen, the nib 7 is carried by a feed-bar loosely fitted in the barrel and slidable under the influence of gravity relatively to a fixed feed-member to and from operative position. The fixed feed-member 3 is screwed into the part 2 of the barrel or is held against rotation therein by a projection on the part 1 of the barrel which screws on to the part 2. The outer end of the part 1 is closed by a spring-pressed cap 14 having a rubber or like stopper 17 to prevent leakage of ink. A finger-piece is provided on the cap to facilitate opening, and a projection thereon engages a notch in the feed-bar 4 to hold the nib in projected position. The nib is attached to the feed-bar by rivets, clips, or springs, and the assembly is freely slidable in the space between the member 3 and the wall of the part 1 of the barrel, projections being provided to prevent rotation and to ensure a clearance between the parts and prevent sticking. Ink is fed to the nib through a passage 19 in the fixed feedmember, the outer end of which may be closed when the nib is in retracted position, to a channel 20 on the movable feed - bar. A space 21 above the feed-member 3 prevents ink from spreading to the cap 14. The part 2 of the barrel may be filled with ink, after removal of the part 1 and associated parts, by means of a filler or by self-filling mechanism which may comprise a sleeve 30 secured in the barrel by the feed-member 3 and carrying a compressible bulb 33. A valve-member 34 formed with flattened sides to permit the flow of ink, shoulders 36 to co-operate with a valve seat in the sleeve, and an air-tube 35 extending into the bulb 33, is mounted in the sleeve and is so arranged that the valve is held open when in position in the pen, but closes on removal for filling. In another modification, the reservoir is closed by a valve controlled by a cap rotatable on the rear end of the barrel. A pocket clip 27 may be provided extending over a recessed part of the barrel.

Filed: 1932-07-29
Abstract: 388,293. Covering cores by winding. ETABLISSEMENTS ROTATISS, 14, Rue Frederick Lemaitre, Paris. July 20, 1932, No. 20498. Convention date, July 31, 1931. [Class 109.] The machine is stopped when the material, such as paper from a roll, or thread from a bobbin 4, breaks or is used up. The material passes from the supply on the counterbalanced plate 3 rotating with the main spindle 2 round a guide 5 into engagement with one of two arms 7, 8 on a ring mounted loosely on the reduced part 2<1> of the spindle. The ring is thereby normally caused to rotate at the same speed as the part 2<1> which is formed with a screw thread of long pitch engaged by one of the arms. When the material breaks &c. the ring is able to rotate slower than the part 2<1> so that it descends and engages a spring-controlled arm 9 and knocks it out of its retaining notch. The arm is thereupon rotated by its spring about its axis 11 and its heel piece moves into engagement with a screw thread on a shaft 13 driven through belt gearing from the main shaft. The shaft is thereby moved endwise, a long key engaged by its driving pulley 15 allowing for this movement. Two discs 17<1> on the shaft 13 engage the main driving belt 17 and move this on to the loose pulley of the machine, whereby this is stopped.

Filed: 1973-05-01
Abstract: 1406924 Synchronization SIEMENS AG 1 May 1973 [2 May 1972] 20623/73 Addition to 1301598 Heading H3A [Also in Division G4] A control circuit for synchronizing a receiver clock signal with a pulse train received from a transmitter S1 comprises: a frequency divider ZA which counts pulses supplied by a pulse generator JG, the initial and final count values being adjustable, and which, when the final value is reached, emits a timing pulse and is reset to the initial value; a final value calculator EWR which, for each transmitted pulse, determines a final value of the divider ZA in dependence on the deviation of the current timing pulse from the transmitted pulse; and means for providing an input signal to the calculator EWR which has a first component proportional to the time integral of the deviations of previous timing pulses, and a second component which is proportional to the deviation of the current timing pulse. Before the arrival of a transmitted' pulse from S1 a nominal final count value is stored in register EWR and is compared with the actual value of divider ZA in a comparator VG1 which produces a reset pulse for the divider whenever the two values are equal. A valve JZO is also fed into integration up/down counter JZA which sets this counter to the value it would assume if there were no errors in the transmitted signal. The output JZ from the integration counter and the output Z from the divider ZA are combined to provide a signal JZ+Z/4 which is applied as a new input to the register by the arrival of a transmitted pulse from S1, which pulse arrives at some arbitrary count Z 1. Register EWR now contains JZ 0 +Z 1 / 4  and thus modifies the final count attained by divider ZA. Comparator VG2 checks whether this transmitted pulse arrives before or after the middle value of the count of divider ZA, and adjust the count of integrator JZA up or down one step accordingly to provide a new output which is used in the next correction to modify the value stored in register EWR, and hence the final count of divider ZA. System details, Fig. 5.-The divider ZA comprises four counter stages Z1, Z2, Z4, Z8, and its output is divided by four by being connected to adder ADD1 with the connection shifted two places. The up/down counters of integrator JZA are also applied to ADD1, and the output from ADD1 are applied to register EWR which consists of a number of bi-stables EWR1, EWR2, EWR4, EWR8, EWR16 each of which has a control input fed with the signal from S1, which as described is a magnetic tape.
