[Also in Division H4] A device for use in the periodic scanning of a narrow strip of terrain extending transversely of the course of flight of an aircraft in which the device is mounted, comprises a rotor 6 (Fig.6) having three scanning mirrors inclined at equal angles to the axis of rotation 15<SP>1</SP> and an optical system for collecting and focussing radiant energy from the mirrors on to a single detector 17, a rotating chopper 15 operable in synchronism with the rotation of 6 to cause beams 7, 7<SP>1</SP> of radiant energy to be alternately incident on the detector. Radiation from the triple-mirror falls on two plane mirrors 8, 8<SP>1</SP> which separate out the beams 7, 7<SP>1</SP>. These beams are focussed by cassegrainian mirror systems 9, 9<SP>1</SP> at a point P lying in the plane of the chopper which is provided with alternate equal reflective and transmissive areas 16<SP>1</SP>, 16. Since the beams 7, 7<SP>1</SP> are focussed at P from different directions, only one beam will be passed by the chopper, rotation of which is synchronized so that the radiation passed comes from one mirror on the three mirror rotor at a time. The radiation may be in the infrared region of the spectrum.

Carbon fibre or other organic fibres may be used in place of glass fibres, and a skin 32 passes round the gunwales and the keel and is secured thereto by adhesive, the skin providing no strength to the structure but merely serving to provide water tightness. Preferably a foamed cross-linked high density polyethylene sheet material is employed. A deck 22 of waterproof cloth is laid on the struts 31 between the gunwales 28, 29 and this deck is provided with an aperture for a sculler (not shown) the aperture being formed by an arrowhead washboard and saxboards at the sides. Riggers are provided for holding oars and an aluminium stabilizing fin protrudes from the bottom of the boat.

Title: Method of and tool for driving fasteners into solid receiving materials
IPC: B25C1/14
Filed: 1968-12-18
Abstract: 1,242,458. Cartridge actuated fastener driving tool. HILTI A.G. 18 Dec., 1968 [29 Jan., 1968], No. 60078/68. Heading B4C. A cartridge actuated fastener driving tool comprises a driving piston having a conical surface 8a, an elastically deformable detent 7, preferably of steel, having a conical surface 7a, which is contacted by the conical surface on the piston during a driving operation, and a body 5 which holds the detent. The body 5 is connected to a housing 1 by shear pins 6, and the housing is screwed on to a barrel 3. In operation and after a fastener has been driven, the majority of the surplus kinetic energy of the piston is converted into heat energy through friction between the piston and the detent and into elastic deformation of the piston and detent. Any remaining energy is transmitted to the body 5 and through the sear pins to the housing 1. If the remaining energy is excessive the pins will shear. In the embodiment of Fig. 2, the detent has a second conical surface 7b which co-operates with a conical surface on a ring 15. The body 5 is supported in the housing 1 by springs 10, 11, a sleeve 13 and spring 14. A guide 4 for receiving fasteners is axially movable in the housing 1. A spring 16 is positioned between the body 5 and the guide. Screwing of the housing to a greater or lesser extent on to the barrel 3 will permit adjustment of the stroke of the piston. Engagement of a screw 20 with one of a plurality of slots 3a on the barrel will lock the housing in an adjusted position. The guide may be held stationary relative to the housing by means of spring urged balls (22) and detents(4a), (Fig. 3, not shown).

As shown the spring 31 engages a guide pin 30 to the body 10 to ensure that one wall of a slot 24a of the plate 24 is maintained in positive engagement with the pin 30. The spring 31 functions to eliminate backlash. The spindle 14 may be rotated by a knob mounted on its free end or by an associated push button mechanism. Any danger of the spindle 14 becoming disconnected from a bearing plate 12 when the carrier plate 24 presses against the bearing plate 12 is obviated by a spring washer 35 and a circlip (37, Fig. 5, not shown) which engages in a recess in a bearing washer 36. A modified bearing washer 36 is disclosed (Fig. 6, not shown). Surrounding the coils 17 are ferrite or other sleeves 20.

Abstract: 1,240,787. Making cartridge fuses. LUCIEN FERRAZ & CIE. 15 Dec., 1969 [17 Dec., 1968], No. 60978/69. Heading B3A. [Also in Division H2] A method of making cartridge fuses comprises forming an end of a tubular body 1 with angularly spaced notches defining teeth 1c, shaping an end cap 3 with teeth 3a corresponding to these teeth 1c so that it may assume a first position in which the teeth 3a are engaged in the notches and a second position in which the teeth 3a abut the teeth 1c, welding fuse elements 6 to the cap 3, engaging this cap in the body 1 in the first position so that the elements 6 project beyond the opposite end of the body, welding the elements 6 to a non-toothed end cap 2, bringing the cap 3 to the second position with the cap 2 abutting the opposite end of the body and fixing the caps 2, 3 in position. The caps are held in place by clips 8, 9, which engage in peripheral grooves 1a, 1b. The body is filled with sand 7 through an aperture 3c in the cap 3 and a corresponding aperture in the clip 9, the apertures then being sealed. The terminal blades 4, 5 may be notched to accommodate clips (10) on which insulated handles are attached for removing the fuse from its support, Fig. 6 (not shown). An indicator head (11) of plastics material may be secured in a depression (9b) in the clip 9 by a retaining wire (12) which melts when the fuse has operated thereby releasing the head, Fig. 7 (not shown).

Abstract: 1,179,999. Electric synchronizing. ENTWICKLUNGSRING SUD. G.m.b.H. 23 Dec., 1968, No. 61104/68. Heading H2L. [Also in Division G5] Information d stored on a magnetic tape I is transferred and registered with stored information e on tape II, the two tapes carrying a time code, and the magnetic heads being located at f. As shown, the tape I is at 2.2 and tape II is at 14.3, the transfer taking place when the start of the stored information d (represented by the number 9.4) reaches the head-position at the same time as the end of the stored information e (represented by the number 20.4). Signals representing the values 2.2 and 14.3 are derived from units 32, 33, which read the code words characterizing the instantaneous positions of the tapes and translate them into a binary code. These signals are applied through storage members 34, 35, to a differential circuit in the form of a digital computer 36, and the difference-signal is applied to a comparator 38. A device 37 delivers a reference signal representing the difference between the numbers 20.4 and 9.4 to the comparator 38, and the errorsignal from the computer is transmitted through a digital-analogue converter 39 and amplifier 40, to oscillator 41 which controls the speed of the unit 31 driving the tape II.

Title: Printing apparatus and method
IPC: H04L9/18
Filed: 1978-11-09
Abstract: A mosaic printer is made secure from unauthorized interception of data by falsifying the needle drive pulse current magnitude and sequence so that electromagnetic leakage radiation cannot be used to determine the alphanumeric data being printed. This falsification is accomplished by a compensation device having compensators energized each print cycle in addition to the printer needle drives in a reciprocal or a pseudorandom manner. The compensators have current consumption characteristics nominally identical to the needle drives and produce substantially identical radiation pulses, making it impossible to correlate the radiated pulse format with the symbol being printed.

Filed: 1979-09-20
Abstract: A mobile container, e.g. a caravan, has headroom for a person to walk within the container when the container is at rest but with a lower internal height when travelling. This is achieved by a floor portion 31 which can be lowered when the container is at rest to give the headroom, thus allowing the height of the remainder of the container to be reduced to reduce wind resistance on the container when it is travelling.
