The box comprises a base 7 and pairs of side walls 8 and 9 carrying flaps 8a and 9a respectively. The flaps 8a have necked tongues 11 at their outer ends which pass through slits 19 in the box walls. The flaps 9a are disposed across the corners of the box body and have depending extensions of angular form which project exteriorly through slits 17 in the said base to constitute the feet of the body. The base corner portions and the lower corner portions of the box walls are of rebated form so that the ventilation passages which extend up from the said corner portions of the base each have at the bottom an inlet opening 30, and the ventilation air from the said passages 25 flows between the tops of the flaps 23 and the lid of the box. In a modification the internal body is divided by a transverse partition (Fig. 9) having a pair of divergent flaps at each end with angularsectioned depending extensions which pass through slits 34 in the base and thus form triangular ventilation passages. A detachable lid with preformed ventilation holes is provided. Alternatively the holes may be formed by punching annular incisions therein, the user removing some or all of the centre portions according to the number of holes required.

Title: Methods for Use in Identifying Multiple Reflections.
Inventor: ANSTEY NIGEL ALLISTER
IPC: G01V1/36
Filed: 1966-06-15
Abstract: 1,195,204. Seismic prospecting. SEISMOGRAPH SERVICE (ENGLAND) Ltd. 15 June, 1967 [15 June, 1966], No. 26644/66. Heading H4D. [Also in Division G1] To identify multiple reflections in a reflection signal obtained in seismic surveying, a synthetic multiple-reflection signal is derived by correlating the reflection signal with a time-reversed representation of itself or of a signal related to or derived from it. The related signal may be an adjacent trace in a seismic section. It is demonstrated that the resulting " retro-correlation " signal cannot include primary reflections, that when polarity-inverted it synthesizes all surface multiple reflections with correct polarity and time relationships, and that first order surface multiples are generated with correct amplitudes while higher-order surface multiples are generated with progressively exaggerated amplitudes. The synthetic signal may be recorded or displayed directly (Fig. 4a) and visually compared with the original reflection signal to identify the multiples, or it may be composited with the reflection signal (Fig. 4b) in adder 47 to suppress the multiples at least partially.. By including the retro-correlator in a feedback loop the synthetic signal (retrocorrelator output inverted) generates all surface multiples with correct amplitudes and may be displayed directly (Fig. 4d), for comparison with the original reflection signal, or composited with the original reflection signal (Fig. 4c) to suppress the multiples. The retro-correlation may be performed substantially as in Specification 1,132,962 using the magnetoresistive correlator of Specification 1,111,331 (see Division G1):

Title: Improvements in Head-Up Display Systems for Aircraft Piloting
IPC: B64D45/00
Filed: 1968-06-06
Abstract: 1,193,791. Head-up display system. THOMSON - CSF. June 6, 1968 [June 9, 1967], No. 27074/68. Heading G2J. In an arrangement for maintaining marks, which are the images of reticles (for example a), in the actual direction of progression of an aircraft in a head up display given by an optical assembly including an image mixer P, a collimator lens L and a semi-reflecting mirror M at an angle of substantially 45 degrees from the optical axis of the lens and the longitudinal axis of the aircraft, some of said reticles being pivotally mounted on rotating means controlled by controlling means for rotating the corresponding reticles by first rotation angles; there are provided a first means 4 for mounting said mirror M pivotally about the optical axis, second means for supporting pivotally about the respective axes of the image mixer the reticles which are not mounted on the rotating means, means 1 for computing from the drift angle of the aircraft a second rotation angle for controlling the first and second means, and third means coupled to the computing means for causing the rotating means to rotate the reticles through an angle equal to the second rotation angle. A collimating lens is employed so that the images of the reticles are seen in the mirror at infinity along with the landscape outside the aircraft. In order to compensate for drift simultaneous rotation through an angle substantially equal to the drift angle is imparted to the semireflecting mirror M and to the reticles. If without the compensation means the reticle would not be able to rotate, an aircraft computer supplies in analogue form a value corresponding to the drift correction angle D to an amplifier 2 which in proportion to D drives a control system 3 pivoting rockers 4 and 5 which carry the mirror M and the reticles respectively about the optical axis of the lens. If the reticles are already rotatable they are mounted on rockers 8 which can be rotated by control arrangements 7 supplied with a drive voltage from computer 1 through an amplifier 6. To compensate for drift the mirror is pivoted as with the fixed reticles and a voltage is added to the control voltage of the control system 7 which is the analogue of the rotation of movement of the mirror and is supplied by a detector 9 which senses the position of the controlled arrangement 4. In modification, the rocker mechanism 8 is provided with a differential system by means of which the movement of its own control system and of the drift correction control system 3 are added. A floating zero mechanism is used to compensate for errors in the positioning of the collimator in the cockpit. The glass M is also provided about an axis parallel to the plane of the lens and is controlled by a motor (17), Fig. 7 (not shown), to compensate for vertical displacements. The circuit used is described in the Specification and shown in Fig. 7 (not shown).

Title: Improvements in and relating to dynamic balancing machines
IPC: G01M1/22
Filed: 1947-10-08
Abstract: 646,040. Balancing rotors. SCOPHONY, Ltd., JONES, P. L. F., and TOWNSHEND, J. H. Oct. 8, 1947, No. 27079. [Class 40 (i)] In a dynamic balancing machine (Fig. 1) a body 10 is rotated in bearings 9, 9<SP>1</SP> by a belt 12, and the bearings are connected through rods 11, 11<SP>1</SP> to pick-up devices 1, 1<SP>1</SP> comprising coils movable in magnetic fields in response to the bearing oscillations. The coil outputs are connected through reversing switches 4, 4<SP>1</SP> to potentiometers 2, 2<SP>1</SP> and a change-over switch 3 enables either balancing plane to be selected for test, and the output of the appropriate pick-up device to be connected in series with a portion of the output of the other pick-up device desired from the slider of its associated potentiometer. The combined output is applied through a reversing switch 5 to a measuring instrument 6 indicating the degree of unbalance and a stroboscopic lamp 7, illuminating a mark 16 on the rotating body, which is observed to determine the angular position of unbalance. In operation, the potentiometer sliders are adjusted so that when the switch 3 is in its left-hand position the instrument 6 indicates the unbalance in the left-hand balancing plane, and vice versa. The switches 4, 4<SP>1</SP> enable the proportionate signal derived from one balancing plane which is to be combined with the signal of the opposite balancing plane, to be phased so as to correctly compensate for the effect of unbalance vibrations from this opposite plane while still phasing the stroboscopic lamp to indicate the position in which the rotor is " heavy " in the plane under investigation. The reversing switch 5 enables the phase of the lamp to be reversed so that it alternatively indicates the " light " position of the rotor. Switches 4, 4<SP>1</SP>, 5 are set up in advance according to the geometry of the rotor and the method of correction, and only switch 3 is operated during testing to select the appropriate balancing plane. The outputs of the pick-up devices may be amplified.

Filed: 1962-07-13
Abstract: 1,008,579. Packaging. GEVAERT PHOTO-PRODUCTEN N.V. July 13, 1962 [July 14, 1961], No. 27096/62. Heading B8C. [Also in Division B6] A moving web 1 of paper or other material, e.g. synthetic plastic material or film, is folded longitudinally, the folding being started at a position 5 along the course of the moving web where the course doubles back on itself, the web being advanced from the position 5 in longitudinally folded condition with the external side of the fold facing the unfolded portion of the web moving up to the position 5. As shown in Fig. 4 the unfolded portion of the web is advanced by feed rollers 17, 18, 19 and the folded portion by feed rollers 20, 21, the latter portion passing between the ends of the rollers 18, 19. In practice the position 5 will not remain in the same place but will tend to move towards or away from the rollers 17-19. In order to obviate such movement the relative speeds of the feed rollers may be controlled by an optical or mechanical system which ensures that the position 5 remains stationary. In a modification, Fig. 5, the feed rollers are omitted and the web is folded by means of conical members 13, 14 which are driven. The conical members may instead be fixed and have a smooth friction-free surface. The conical members may be replaced by shaped plates, Fig. 6 (not shown). If a fold having a rectangular profile is required the conical members are spaced apart and the web 1 is guided between them by a member 23. A web of X-ray film 24 is introduced into a folded web 25 of packing paper, the fold being produced in accordance with the method set out above, and the combined webs are severed by a cutting device 28.

Title: Process for the preparation of substantially pure titanium metal
IPC: C25C3/28
Filed: 1953-10-05
Abstract: 744,396. Electrolytic production of titanium. NORTON GRINDING WHEEL CO., Ltd. Oct. 5, 1953 [Oct. 4, 1952], No. 27224/53. Class 41. Pure titanium is produced as a powder by electrolytic deposition in a cell containing one or more fused halides, preferably chlorides, of lithium, sodium, potassium, magnesium, calcium, and aluminium, and titanium carbide isolated from the cathode, e.g. as the anode. preferably the titanium carbide is in powder form in a cup surrounding the anode but it may be a sintered rod forming the anode. The cell is run at 500-600‹ C. and argon is passed continuously through the cell while chlorine may also be passed continuously to prevent deposition of the metals of the halides, especially magnesium, calcium, and aluminium which are difficult to remove from titanium. If desired powdered titanium carbide may be converted to titanium tetrachloride by passing chlorine into the heated cell before electrolysis. As shown, the cell housed in a container 22 packed with heat insulating material 31 and surrounded by an electric heater 28 comprises a tubular cathode 1 of titanium, nickel, or stainless steel closed at the lower end and screwed at the upper end into a steel coverplate 14 resting on an asbestos board 21 forming the lid of the container. The plate 14 carries a threaded steel plug 13 in which rests a ceramic cap 10 supporting a porous ceramic tubular partition 3 which is gripped by an asbestos washer for the plug 13 and from which depends a porous cup 4 containing powdered titanium carbide. A hollow carbon anode 7 surrounded for most of its length by a non-porous ceramic tube 8 passes through the cap 10, anode and tube being supported by releasable collars resting on the cap. Argon is passed into the cell through the tube 50 and chlorine is supplied through the hollow anode, a slow leak occurring around the cap 10. If chlorine is supplied continuously the top of the cell may be modified to collect and re-cycle the gas. A tube 57 is provided in the casing for a thermoelectric thermometer. The ceramics used may be different forms of alumina. If a sintered titanium rod is used as the anode, the sleeve 8 and the cup 4 may be omitted. When deposition of titanium is complete and before the melt has set the plug 13 and its associated assembly is replaced by a similar plug carrying an airtight cap through which a siphon tube passes so that by increasing the argon pressure the bulk of the liquid salt may be drawn off. When the mixture of halides and titanium in powder form has set it is scraped out and the titanium is freed from the halides either by vacuum distillation in the case of lithium, sodium, and potassium halides or by organic solvents in the case of magnesium, calcium, aluminium, and lithium halides. The resulting titanium sponge metal is consolidated into ingots by heating in an argon atmosphere and casting into graphite moulds or pressing into blocks.
