Title: Activating device for ground mines
Inventor: LEVERATTO RENZO
IPC: F42C19/06
Filed: 1986-05-13
Abstract: An activating device for ground mines comprises a detonator-holding stem 3 movable into an operative position by hydrostatic pressure upon flooding chamber 7 and two springs 12, 16 opposing said stem movement and acting in parallel with each other. One of these is a release spring 12 disengageable from the stem, and the other is a back up spring 16. A cut-off diaphragm 24 is connected with one end to the stem and is rotated by cam action to put the detonator 5 in communication with a firing charge 26, as the stem moves to the end of its travel. An electric safety circuit 17 holds the detonator shorted out and disconnected from the electric circuitry of the activating device when the stem is located other than in its travel end position. A control assembly 4 controls the initial movements of the stem and includes a sleeve 8 disengageable from the stem and in direct contact with the release spring. A cutout 27 is formed in the outer shell of the device, and a latch 28 is biased into said cutout and shaped and positioned to block the return movement of the stem from said operative position, thus preventing deactivation. <IMAGE>

Patent GB-878703-A (GB)
Abstract: 878,703. Echo sounding. RAYTHEON CO. March 11, 1958 [March 28, 1957], No. 7874/58. Class 40(7) [Also in Group XIX] A keying and recording apparatus comprises an endless belt carrying a keying stylus and a writing stylus which passes over a recording paper. A flexible non-conducting belt 51 passes round pulleys 45, 48, Figs. 4 and 10 (part shown), one of which is driven by a motor. The belt rides in grooves in a guide bar 46 and carries metal slippers in which are mounted the writing stylus 43 and the keying stylus 62, and which press against conducting rails 53, 54 during part of their travel. A non-conducting keying bar 63 has embedded in it two spaced contacts 69, 70. As the belt is driven the keying stylus touches these contacts and causes a circuit to be completed through the rail 54 and a selected contact 69 or 70; this keying action triggers a circuit which includes a sonic transmitter. The signals to be recorded, for example echoes in depth sounding, are fed as electrical signals to the rail 53 and pass to the writing stylus which marks the electro-sensitive recording paper. The spacing between the styli and the position of the contacts 69, 70 may be arranged so that received signals are recorded either directly after or at a predetermined time after the keying action. Thus in a depth sounder two depth ranges can be recorded. The belt may be driven at either of two speeds so that the recording scale is correspondingly magnified. Means are provided for adjusting the position of the keying bar and for adjusting the tension in the belt.

Abstract: The device for use on door of cabinet or cupboard and resistant to operation by small children comprises an elongate catch 16 arranged for longitudinal sliding movement within a bracket 12 secured to door frame 2, one end portion 16b of catch 16 being engageable with a keeper 20 fixed to the door 14, a heel member 24 located adjacent the other end of catch 16 and being rotatable about the longitudinal axis of the catch to change the device from an unlocked state in which longitudinal movement of the catch 16 within the bracket 12 is permitted to a locked state in which said longitudinal movement is prevented. As shown, the cylindrical bracket 12 has two slots in its inner wall, a main slot 30 extending substantially parallel to the longitudinal axis and a second bayonet-type slot 32 extending laterally of the main slot. Heel member 24 and catch 16 have protrusions 32a, 30a engageable with the slots 30, 32. When the door 14 is closed catch 16 and keeper 20 interengage and they may be disengaged by upward pressure on heel member 24. However by pressing upwards on heel member 24 and simultaneously rotating in direction A protrusion 32a enters slot 32 the upward pressure is released a spring 46 biases protrusion 32a in slot 32 to prevent catch 16 being raised. <IMAGE>

Title: Relay driving circuit using a thyristor and a local capacitor
Inventor: ANZAI TAKEO
IPC: H01H47/04
Filed: 1989-04-27
Abstract: To test a communication line 4, which normally connects a central station 40 to a terminal 20, a d.c. signal is sent over the line 4 to a relay circuit via an a.c. blocking choke 3, so that a capacitor 7 charges up to a voltage causing a thyristor 10 to turn on to energise a relay coil 1, whereby relay contacts 2 switch the line 4 from the terminal 20 to test equipment 30. The arrangement can operate with a higher upper limit of the d.c resistance of the line 4 since if that resistance is high the capacitor 7 will provide the pull-in current for the coil 1 as well as the triggering voltage for thyristor 10, the holding current for the coil 1 thereafter being supplied over the line 4. <IMAGE>

Title: Method and apparatus for radio transmission using pulses of random polarity
Inventor: CORDES PAUL BEAUMONT
IPC: G01S13/02
Filed: 1989-11-17
Abstract: The maximum power in any spectral line of a spectrum which would represent radio emission (for example in ground probing radar) is reduced by splitting each line into a number of lines each of lower power. The original train of pulses 10 is used to generate both positive-going and negative-going pulses 32, 34 using the logic output of a PRBS (pseudo-random binary sequence) generator 16 to steer pulses to either of two pulse generators 18, 20. Their outputs are combined by a power combiner 26. A sampling receiver system (Fig. 6) is phase controlled by the output of the PRBS generator. Typically a spectrum which would have resulted from transmission of pulses 1ns wide at 12ns spacing has the maximum energy per line reduced from 1300nW by a factor of 2<16> by splitting each line into 2<16> further lines where 2<16> is the length of the PRBS code. <IMAGE>

Title: Measuring surface characteristics
Inventor: MANSFIELD DANIEL
IPC: G06T7/00
Filed: 1990-04-12
Abstract: Apparatus for measuring surface roughness utilizes diffraction patterns derived from the surface under test. The energies in the different orders are detected and processed utilizing various different algorithms dependent upon a number of factors such as the number of orders in the diffraction pattern and asymmetry in the diffraction pattern. Various filter functions both for the diffraction pattern itself and for values of surface roughness after measurement are disclosed. One algorithm for measuring surface roughness involves comparison of values representing the energy orders with reference values, preferably reference values obtained by an interpolatation operation between one set of reference values representative of a diffraction pattern from a symmetrical surface and another set representative of a diffraction pattern from an asymmetrical surface.

Title: Recovering silver values from chloride residues
Inventor: PICKLES CHRISTOPHER ADRIAN
IPC: C22B11/02
Filed: 1990-09-28
Abstract: Silver values are recovered from silver chloride or mixed chlorides including silver chloride by a pyrometallurgical process in which chloride residues are smelted with an agent such as sodium silicate that provides alkali metal oxide without generating gases, such as carbon dioxide, that would result in foaming during smelting, metallic silver being separated from a slag. A flux, such as borax, is added to reduce the slag viscosity. Carbon may be added to the smelting step in amount up to 4%.

Title: Making plural tobacco tiller streams
Inventor: HEITMANN UWE
IPC: A24C5/39
Filed: 1991-01-17
Abstract: A relatively wide first layer 3 of tobacco particles is broken up into several narrow second 9 and several narrow third layers 8. The second layers are converted into a first tobacco filler stream 14 which is trimmed to form a rod-like filler ready to be draped into a web of cigarette paper, and the third layers are converted into a second tobacco filler stream which is ready to be trimmed to form a rod-like filler ready to be draped into a web of cigarette paper. The tobacco layers are caused to advance along and closely follow concave sides of guide surfaces 12, 11 and are propelled along the respective surfaces by streams of compressed air. Subdivision of the first layer into several second and several third layers reduces the likelihood of unmixing or dehomogenization of the mixtures of tobacco particles which are about to be converted into plural tobacco filler streams. <IMAGE>
