Abstract: 216,719. Peters, S. E. July 3, 1923. Reservoir pens.-In a reservoir pen of the type in which a collapsable sac is compressed through the medium of a rotatable element, a non-rotatable member is connected to and moves in the same longitudinal direction as, the rotatable element. The rotatable member 18, which acts as a closure for the barrel 10, screws into the barrel and is connected to a sleeve 20 in such a manner that relative longitudinal motion is impossible. The sleeve 20 is provided with a pin 22, which, when the sleeve is drawn outwardly by unscrewing the cap 18, acts on a cam surface formed on a lever 24 to rock it about its pivot 25. The lever is held against displacement by passing the pivot pin 25 through lugs thereon. The lever is pivoted at its forward end to a presser-bar 26 secured on the sac 11, the pivot 27 being nearer to the rear end of the bar, so that, on operation, the rear end of the sac is compressed first. The rear end of the lever 24 is accommodated in a slot in the sleeve 20, and, when the cap 18 is screwed home, the wall of the slot engages the. lever to return it to normal position. A hook on the rear end of the lever, which engages the pin 22, acts as a stop for limiting the movement of the sleeve 20 and' cap 18. The lever' 24 is adapted to be held in an intermediate position so that the filling operation can be interrupted and resumed' without thenecessity of discharging the ink previously drawn in.

Title: Package and method of sealing same
Inventor: SMITH JAMES EDWARD
IPC: B65D75/66
Filed: 1961-05-15
Abstract: 945,399. Labelling; packages. CROWN ZELLERBACH CORPORATION. May 15, 1961, No. 17557/61. Headings B8C and B8F. Relates to the packaging of articles such as bread 29, Fig. 5, in which the end folds of a wrapper 28 are sealed by a label or seal 2 having a thermoplastic heat-sealable coating thereon, and the label is applied to the folds by relative movement between the label and the packaged article in a direction transverse to the plane of the folds and while the packaged article is moving in a direction parallel to the plane of the folds, heat and pressure being applied to the label to effect sealing. According to the invention the thermoplastic coating on the label 2, Fig. 3, is in the form of projections 21 which serve to minimize lateral slippage of the label relative to the folds during application of the label. These projections 21 may be arranged in an oblique pattern as shown in Fig. 1 or in a dotted or in a grid-like criss-cross pattern. One or two opposite side portions 24 of the label are free of coating to provide a pull tab and the label is adhered to the end folds with the function line L, Figs. 1, 5, between the pull tab 24 and the coated area below the top end of the outermost fold 32 to facilitate ready pulling of the fold 32 downwardly on its hinge connection 32a upon downward pull of the tab. The wrapper is preferably of polyethylene film or regenerated cellulose but may also comprise wax coated paper or other materials. The label coating consists essentially of at least 50% by weight polyethylene and the remainder additive material imparting to the coating decrease in melting point and viscosity and increase in tackiness at about its melting point compared to such properties of polyethylene alone. Specification 945,398 is referred to.

Title: Signal Integrating Circuit Arrangement.
Inventor: CHAPTER COLIN FALCONER
IPC: G01S7/28
Filed: 1967-04-17
Abstract: 1,169,435. Pulse radar. PHILCO-FORD CORP. 17 April, 1967, No. 17594/67. Heading H4D. A signal integrating circuit arrangement for improving the signal-to-noise and signal-toclutter ratio of a radar system comprises a delay line having its output coupled to its input to form a recirculatory loop, by way of means for modulating the phase of a carrier wave circulating in the loop in accordance with the signal to be integrated and means for adding to the modulated carrier wave a reference signal having the frequency of the carrier wave and having a predetermined reference phase. As shown in Fig. 1, video pulses representing target-reflected echo signals forming the input 24 are applied to a phase deviator 10, this deviator being situated in the circulating loop together with an electroacoustic delay line 12 and adder 14. The delay time of line 12 is approximately equal to the desired pulse repetition period of the radar system. Amplifiers 16, 18, 19 compensate for attenuation in the loop, 20, 22 hold the amplitude gain of the recirculating carrier wave at unity. Transversal filter 23 shapes the over-all phase and amplitude response of the loop. Phase deviator 10 serves to introduce momentary phase in the recirculating carrier wave, and a controlled degeneration of these deviations is obtained by a reference carrier oscillator 30 and variable gain amplifier 32. Oscillator 30 provides a carrier wave at the reference or zero-signal phase of the recirculating carrier wave at the output of limiter 20. In operation, the stored intelligence in the recirculating loop is degenerated by adding to that loop in adder 14 the carrier wave derived from oscillator 30. The phase correspondence between the oscillator wave and loop carrier wave is obtained by a phase detector 34 having inputs from limiter 20 and oscillator 30. A frequency control signal is supplied by phase detector 34 to oscillator 30 by a low-pass filter 36 to ensure that the oscillator frequency is equal to the frequency of the recirculating carrier wave. Detector 34 also supplies the integrated video output signal to video amplifier 38. A conventional timing loop 40 is coupled from the output of filter 23 to amplifier 16 to provide timing pulses to the radar transmitter to ensure that the interpulse period of the radar system is exactly equal to the total loop delay. The operation of the circuit arrangement is described with reference to waveform diagrams (Figs. 6, 7, not shown). The phase deviator 10, transversal filter 23, and phase detector 34 are described in greater detail with reference to Figs. 2, 4 (not shown).

Abstract: 1522545 Elevator control system WESTINGHOUSE ELECTRIC CORP 4 May 1976 [16 May 1975] 18146/76 Heading G2-3 An elevator system has a car position indicator 40 in a car 12 and a power supply therefor. A pick-up 30 optically or magnetically detects movements of openings in the governor sheave to give the advanced floor position of the car. Floor selector 34 produces distance pulses from pulse detector 32 and feeds reversible counter 70 which gives the advanced car position. The binary representation of discrete advanced floor position from counter 72 is converted by programmable read only memory 74 to a binary word describing that floor location. The outputs of counter 70 and memory 74 are compared in unit 76, equality indicating that slowdown must be initiated at this point. If deceleration is not initiated, comparator 76 activates indexer 78 which changes counter 72, and hence memory 74 produces a word for the next floor in the travel direction. Another programmable read only memory in the car receives advanced car position signals AVP0- AVP4 and gives two four bit BCD words giving the desired display rotation which drive two digits of a liquid crystal display 40, e.g. of the field effect or dynamic scattering type, or an electro-phoretic display, Figs. 2A, 2B (not shown). If the logic is COS/MOS and the display is a field effect type, a Zener diode/resistor power supply can be used in the car which is connected to a 125 volt supply. The read only memory is the car is made compatible with the Zener diode/resistor power supply by operating it intermittently to greatly reduce average power consumption. Latches are strobed when the memory is activated to preserve the output thereof until the next power supply pulse is applied to the memory.
