Abstract: 1,105,089. Writing instruments. FILLER & FIEBIG G.m.b.H. 29 Dec., 1965 [5 Jan., 1965], No. 55117/65. Heading B6P. In a writing instrument, particularly a tubular-point stencilling pen, employing cartridge refills, a device which has to be removed before the pen can be manipulated to cause a blade to rupture a sealing cap on the cartridge, is provided by the manufacturer. In one form, Fig. 1, the device is a ring 6 disposed between shoulders on the body part 3 and head 1 of the pen, which ring has to be removed before the parts 1, 3 can be screwed completely together to cause a blade 8 on the part 1 to cut out a disc from the closure cap 5 of the cartridge 4. The ring 6 may be removed by unscrewing the parts 1, 3, or it may have a weakened part so that pulling on a finger piece 7 fractures it. If the blade 8 is provided on the writing unit 2 (Figs. 9, 16 . . . 18, 23), the ring may be situated between shoulders on the parts 1, 2. Instead of a ring 6, a lacquer seal (10, Fig. 8) may be situated between the shoulders, the seal being squeezed out when the parts 1, 3 are screwed together. In another construction (Fig. 10), wherein a plunger (11) in the part 3 is urged by a spring (12) to press the cartridge 4 against the blade 8, a seal or ring 6 on the plunger has to be removed to allow the plunger to move inwardly sufficiently to cause the blade to fracture the cartridge cap. The cartridge cap 5 may be detached completely from the cartridge 4 by the blade 8, or a disc thereof may be cut out, or the knife may merely pierce the cap. Various forms of blades 8 (Figs. 2, 14, 15, 16, 19, 21, 22, 29) and cartridge caps (Figs. 24-27) are described.

Title: Apparatus for and methods of seismic prospecting
IPC: G01V1/24
Filed: 1971-12-04
Abstract: 1412399 Seismic exploration systems ELECTROLOCATION Ltd 1 Dec 1972 [4 Dec 1971] 56387/71 Heading H4D A seismic exploration method comprises recording signals corresponding to a generated seismic pulse and the subterranean reflection response in first and second channels respectively, using the played back pulse signal to initiate re-recording of the reflection signal and recording of a tone burst in continuation of the second and first channels respectively, and making visual tracings of the played back rerecorded signal over the duration of the recorded tone burst. In the Fig. 3, embodiment a rod 17, attached to a hammer used as the seismic source, operates switch 16 to turn on tape recorder 19 just before the hammer head impacts the ground, so that the tape runs up to its correct speed (7 in./sec.) before recording of resulting reflection signals starts. The impact instant is recorded as a pulse in a first channel by use of a transducer on the hammer. Reflection signals from a geophone are recorded in a second channel. The tape is then played back and the pulse in the first channel is used to initiate (a) recording of a tone burst, from oscillator 30, in a first channel of recorder 25 and (b) re-recording of the second channel signals in a second channel of recorder 25. Played back second channel signals from recorder 25 are obtained as pulses by including Schmitt and differentiator circuits at either 24a or 35. These pulses are traced by a digital plotter 32, the playback and plotting being synchronized by the recorded tone burst. The playback speeds of recorders 24 and 25 may be lower (e.g. 15/16 in./sec.) than the recording speeds to expand the time scale of the signals. The geophone may be short-circuited or electromagnetically damped at the impact instant to avoid signal distortions.

Abstract: 1367626 Switches held set and freed mechanically CAV Ltd 19 Nov 1971 [1 Dec 1970] 56982/70 Heading H1N A cam operated switch comprises a bridging contact unit 16 (Fig. 2) carrying two sets of bridging contacts 18 biased away from sets of fixed contacts 14, 15 by spring 19; and a resiliently biased latching mechanism 27 mounted for free rotation around the shaft 21 which carries the operating cam 23. The rotation of the shaft 21 is limited to about 180 degrees anticlockwise by stop member 24 co-operating with portion 25. A blade 31 secured to the housing wall 12, passes below the cam and has an edge which abuts the face 33 of the latching member, retaining it against the action of the resilient bias provided by spring 28. On operation, the cam depresses the blade 31 and the push member 32 below it, this action being transmitted to the contact carrier 16 via the leaf spring 20. After engagement of the contacts, further cam rotation causes the blade to disengage the latch which is free to rotate, within the limit imposed by stop members 29 and 30, and latch the switch closed, excess movement of the push member being accommodated by the spring 20. Reverse rotation of the shaft causes the cam, towards the end of its travel, to engage a pin 34 on the latching member and reset it on the spring blade 31, the contact member being released and disengaging the fixed contacts as the spring blade lifts. A further switch 36, e.g. a microswitch. may be operated by a cam track on a further portion of the cam to open a circuit prior to opening of the main contacts.

T30 is fed from a constant current transistor T33 and is emitter coupled to T31 whose collector circuit includes a fixed phase shift circuit C37, R36 driving a transistor 40. The resulting signal at T40 emitter is combined in T38 collector circuit with the signal arising from T38 itself due to the input to T30 base from a burst oscillator (19, Fig. 1, not shown), so that at T38 collector the output signal is dependent upon the input at T30 base and also the settina of R51, and constitutes the desired adjustable phase signal. T38 collector output is connected through emitter follower T57 to a limiting amplifier T58, T59, T61, the collector load of T59 including R65, R67, C68, C69, and L66 from which 90 degrees separated reference signals are taken, and fed respectively to driver circuits T71, T76, T77 and T82, T83, T84. Signal lines are taken respectively from T77, emitter and T71 emitter, the latter being decoupled by C73, to the bases of T98, T99 (Fig. 2B) and T101, T102 of a demodulator 95. Similarly T84, T82 drive a second demodulator 100. The demodulators include an arrangement of emitter-coupled pairs, and their outputs are variously combined to drive output circuits giving red, green and blue colour difference signals. These output circuits each include a Darlington pair T113, T115 driving a series connected pair T116, T118 the output of one of which T116 controls via a Zener diode the output of the other. Reference direct voltages for the demodulators and output circuits are produced by T13, T32, T113.

Abstract: 1379568 Wheel detector ABEX CORP 14 Dec 1971 [14 Dec 1970 29 Nov 1971] 58099/71  Heading B7N [Also in Division G1] Apparatus for detecting moving metal objects, e.g. the wheels of a railway vehicle, comprises at least two sensing coils, each tuned to the same operating frequency, connected in series in consecutive arms of a bridge circuit and positioned sequentially along the path of the moving object, an oscillator incorporated in two additional arms of the bridge for applying signals at the operating frequency and in opposite phase to the two end sensing coils of the series and synchronous detector means connected to the bridge for demodulating and developing two output signals representing the speed and direction of movement of the object. Coils 21, 22 are tuned by capacitors 29, 30 and fed in antiphase from oscillator 39. The output from the bridge 40 at terminals 31, 32, 34 is connected to synchronous detectors 41, 42 which supply on lines 43, 33, a first pulse of one polarity followed by a second pulse of opposite polarity which are used in utilization device 68 to develop the speed and direction of movement signals. Reference circuit 45 monitors and controls the balance of the bridge input from the oscillator and A.G.C. unit 49 compares the bridge output to a reference to regulate the amplitude of the oscillator output. In a further arrangement, Figs. 3-11 (not shown) for overcoming the ambiguity which can arise when, e.g. a rail wheel stops over a first coil and then moves off in the opposite direction, three series-connected and sequentially positioned tuned coils are used which are monitored in two pairs to provide an unambiguous signal sequence to the utilization device.  The coils which have non-magnetic cores have large cross-sectional dimensions compared with their length and are mounted with the coil axis normal to the object path. In the three coil arrangement mutual coupling between the inner coil and the two outers is reduced by winding compensating turns on the inner coil in series with each of the outer coils.
