Title: Improvements in lipstick holders
Inventor: FLYNN JOHN LESLIE
IPC: A45D40/06
Filed: 1950-12-04
Abstract: 695,035. Lipstick holders. ROTHSCHILD, A. G. DE, ROTHSCHILD, E. L. DE, and ROTHSCHILDS CONTINUATION, Ltd., [trading as ROTHSCHILD & SONS, N. M.]. Nov. 26, 1951 [Dec. 4, 1950], No. 29650/50. Class 18 In a screw feed type lipstick holder, the upper ends of the axial and helical slots are open and coincide when the stick is in its fully projected position, whereby the cup may be removed or replaced. In one embodiment, the helical slot 11 terminates in an axial length 24 which, when engaged by the pin 21 of the cup 20, limits further relative rotation between the slotted tubes. In another form (not shown) a pin near the base of the axially slotted tube is engaged by a shoulder on the other tube to ensure coincidence of the slot ends when the stick is fully projected. In a further embodiment, the axial slot 6 terminates in a narrow portion 25 acting to prevent further projection of the stick in normal use, but the pin 21 may be forced into this portion by additional twisting of the tubes, which also brings the end of the slot 11 into line with the slot 6. An outwardly extending bridge 27 reinforces the helically slotted tube. The cup may have a hole 28 for the insertion of a pin, or be knurled, to assist its withdrawal from the stick. Specifications 667,104, 686,985 and 687,064 are referred to.

Title: Improvements in or relating to excitation systems for alternators
Inventor: BACON KENNETH FRANK
IPC: H02P9/00
Filed: 1960-08-29
Abstract: 935,483. Alternators; automatic voltage control. MULLARD Ltd. Aug. 24, 1961 [Aug. 29, 1960], No. 29720/60. Classes 35 and 38 (4). An alternator excitation system comprises two sources connected in parallel with each other and supplying current to the field winding, one source providing a rectified current proportional to the output current and the other providing a rectified current dependent upon the output voltage of the alternator, the output voltage of the alternator being automatically regulated by adjusting the voltage of the second source in dependence on changes in the output voltage wherein the adjusted voltage of the second source is augmented by a voltage component dependent upon the voltage drop across the field winding. The field current Ie is compounded from two currents Iv and Ic. Fig. 1 (not shown) and Fig. 3, the former current being derived from a silicon controlled rectifier bridge regulator 14 controlled by an error voltage produced in a comparator 17 and the latter current from the output current of the alternator via rectifying bridge 12. In order to overcome the back bias across diode D1 due to the voltage drop across the field winding 5 caused by the current Ic, the output voltage of the regulator 14 is augmented by a feed forward source 19 providing a voltage drop equal to the voltage drop IcR produced by current Ic across the field, with the result that the gain of the D.C. amplifier 18 can be reduced with increase in stability. Since in practice the field resistance R is not constant and can vary considerably with temperature it is necessary to monitor the voltage across R, subtract from it the contribution due to current Iv and use the resultant to control the feed forward voltage source 19. In order to eliminate the necessity of having an additional source 19, the regulator 14 may be controlled by an error signal, Fig. 4, comprising a first signal (1) due to the alternator output voltage and a second signal (2) equal to a fraction of the voltage across the field minus a voltage equal to the maximum contribution from Iv under any condition (Iv max R max) which may be carried out using a battery. The circuit of signal (2) also includes a potential divider for reducing the initial voltage to the desired fraction. Specification 935,482 is referred to.

IPC: G01L1/00
Filed: 1964-07-24
Abstract: 1,092,952. Measuring pressure electrically. MINISTER OF TECHNOLOGY. Oct. 25, 1965 [July 24, 1964; April 2, 1965], Nos. 29756/64 and 14029/65. Heading G1N. In a pressure transducer, a metal element 3, Fig. 2, is clamped between two electrically insulating members 1, 2, at least one of which is electrically charged, so that a change in pressure across the insulating members produces a change in the overall proximity, on a macroscopic or microscopic scale, of the metal element to the charged insulating member, thereby inducing a charge on the metal element and a current in a circuit connected to it. In all the embodiments the metal part is connected to earth through a high resistance 6, Fig. 1 (not shown), in parallel with a voltage detector or through a cathode ray oscilloscope. In one embodiment, a convoluted wire 3, see also Fig. 1 (not shown), is clamped between two plates 1, 2 of hard resilient plastics material e.g. polymethylmethacrylate. One or both of the plates may be changed before assembly, e.g. by heating them to softening point when in contact with an earthed metal plate. In a second embodiment, a tin foil (13), Fig. 3 (not shown), is positioned between insulating plates (11), (12), e.g. of polymethyl-methacrylate and is cemented to the latter plate. The two plates are clamped together by an adjustable earthed clamp (17), the plate (11) being cemented to one end of a steel rod (14) and the plate (12) being held against it by clamping plate (16), through a rubber block (15). The adjacent surfaces of the plates may be charged as before. The external pressure is applied to the steel rod (14) by a pressure bar (19). In a third embodiment, a tin foil 26, Figs.4 and 5 (former not shown), is attached to an insulating rubber sheet 25 and held between this sheet and a thin disc 27 of polymethylmethacrylate by two plates 20, 21 of the same material, clamped together by bolts 22. Rubber springs 23 are fitted between the bolts and plate 21 so that the static pressure may be adjusted. The surface of the tin foil is roughed by placing it against a rough surface while rubber adhesive, by which it is attached to the sheet 25, is drying. The disc 27 is charged as before. This transducer is attached to the pressure transmitting device by a bolt 24. In a further modification, the device may be of a multiple form comprising a number of insulating and metal plate-like parts clamped together alternately. The transducer can be used for measuring impacts, vibrations and in conjunction with an inertia mass in an accelerometer.

Title: Methods and apparatus for determining the shape of a cavity
IPC: E21B47/04
Filed: 1973-06-22
Abstract: 1399977 Echo-ranging systems INSTITUT FRANCAIS DE PETROLE 22 June 1973 [22 June 1972] 29829/73 Heading H4D The shape of a cavity is determined by transmitting a beam of sonic pulses towards various parts of the cavity wall from a series of reference locations in the cavity, measuring the pulse echo times a plurality of times for each part for each location, selecting sets of echoes for which the measured time is substantially the same for each measurement of the plurality (thereby eliminating spurious echo times), and averaging the echo times within any set. In the Fig. 1 embodiment a sonde 1 passed through a tube 2 in the cavity has a sonic beam which is stepped through n angular directions in which of m horizontal sections. At each of the nm positions, I (#2) pulses are transmitted and their respective echo trains from the wall and from intervening matter are received. The echoes of a train are sorted (Fig. 3, not shown) into p "range bins" defined by a p-stage shift register (3) clocked at 10 mS. intervals. The precise echo time within a bin is determined by gating 1mS. clock pulses to a counter (Ak) respectively associated with the bin. After I measurements the counter will have accumulated a measure of the sum of the times of N echoes falling within that bin. The number N is registered in a second counter (A<SP>1</SP>k) respectively associated with the bin. After the I measurements the respective numbers N for the different bins are compared one at a time with a threshold number S. If N>S the echoes are assumed valid (i.e. are from the wall) the average echo time in a bin is computed by dividing the sum for that bin by the respective N value, and the echo times and numbers are transferred to a memory. The interface at z 0  between two fluids in the cavity can be located on the basis that when the sonic beam intersects the interface a transmitted pulse will give rise to two time-separated echoes from a given wall part, due to one beam portion traversing one fluid and another portion traversing the other or both fluids. When the beam axis is at z 0  this time separation will be a maximum, directly proportional to one of the two echo times. A counter-timer circuit is provided (Fig. 8, not shown) which checks for proportionality of the average separation (over the I measurements) to the average of the earlier of the two echo times. Echo signals may be recorded prior to the above signal processing; magnetic and variable density optical recording are mentioned.

Abstract: 934,414. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 9, 1961 [Sept. 2, 1960], No. 30370/60. Class 38 (5). [Also in Groups XXXVIII and XL (c)] A monitoring system comprises means for producing an electrical signal corresponding in magnitude to the state of the apparatus being monitored and for actuating an alarm when this magnitude falls below a first predetermined value or increases above a second predetermined value. The invention is described in connection with a transmitter-receiver warning device which may be of the kind disclosed in Specification 876,998 to indicate the proximity of two relatively moving bodies (e.g. two cranes or a crane and a fixed wall) comprising a transmitter T (Fig. 1) and associated transducer S and a receiver R and its associated transducer M. To produce the signal corresponding in magnitude to the operational state of the apparatus low impedance devices R 1 , R 2  are inserted in series with the transmitter and receiver channels respectively and connected by a circuit including a high impedance R 3 , the arrangement being such that faults in either the transmitter or receiver circuits then result in the production of a signal output from the receiver which is either very much lower or very much greater than the signal output obtained when the apparatus is working normally. The receiver output signal then operates two relays C 1 , C 2 , one operating when the receiver output falls below and the other when it increases above the respective predetermined values, the relays operating respective groups of contacts M 1 , M 3 , M 2 , M 4  and W 1 , W 3 , W 2 , W 4  (shown in their unoperated conditions in Fig. 2). During normal operation of the apparatus contacts M 1 , M 2  close and M 3 , M 4  open, the contacts W remaining in the positions shown. When a fault occurs which results in a low signal output from the receiver the M contacts revert to the positions shown, the opening of the circuit of relay AL1 results in the operation of a first alarm and the closing of the circuit of relay AL2 results in the simultaneous operation of a second alarm. When a fault occurs which results in a high signal output from the receiver the contacts W operate and produce a similar operation of the alarm relays AL1, AL2.
