Abstract: ABSTRACT OF THE DISCLOSURE     A pattern tracer and method of tracing in which the movement  of  a  tracing element along a pattern  is controlled in accordance with an effective forward offset which is selectively less than the actual forward offset to optimize the tracing for speeds less than the maximum tracer speed.  The effective forward offset is established by providing control angles which are based on the pattern angles as detected in accordance with a selected criterion depending upon the type of pattern curve detected.  The control angles are either calculated from the detected pattern angles or are selected from previously stored pattern angles.  A kerf setting for lateral offset of the tracing element from the pattern is partially defined by the actual forward offset,  so that changes in the effec-tive forward offset do not cause any corresponding changes to the lateral offset or require changes to the kerf setting.

Abstract: ABSTRACT OF THE DISCLOSURE      A post-deflection accelerating and scan expansion lens system (10) is disclosed which may be used in a cathode ray tube (12).  The lens system comprises an accelerating and scan expansion lens (70) of the quadruple type including a pair of coaxial cylindrical electrodes (72, 74) and first and second compensating lenses (66, 78) on opposite ends thereof to provide a bright image of the desired size in sharp focus and great detail on a fluorescent screen in such tube.  The first compensating lens (66) is supported adjacent the input of the accelerating and scan expansion lens to provide a linear magnification of the amount of electron beam deflection produced by the vertical and horizontal deflection plates (46, 48 and 50, 52).  The second compensating lens (78) includes a single electrode having an aperture (79) with opposed notches (122, 124) in the edge of the aperture on opposite sides of the electron beam axis (28) and is positioned adjacent the output of the accelerating and scan expansion lens to provide corrected geometry of the image displayed on the fluorescent screen.

Abstract: Internal Combustion Engine With Air-Fuel Mixture Heating Abstract An internal combustion engine (1) includes a supple-mental fuel passage (26, 27) which connects the carburetor (9) to the exhaust chest cover (28).  A supplemental air inlet having a metering orifice (36) and passage (35) connects to the supplemental fuel passage.  The resultant air-fuel mixture is heated before entry into the combustion chamber by passing the mixture through a heating passage (32) directly in front of the exhaust ports (13).  When the engine is at idle with a completely closed throttle valve (19), the entire air-fuel supply for the engine is provided through the supplemental fuel and air passages and is heated in the heating passage prior to combustion.  At increasingly open throttle, air-fuel is increasingly provided from the conventional primary carburetor output, with the heated air-fuel mixture being supplied in gradually decreasing amounts.

Abstract: SWITCHING OF PROGRAMMING ROUTINE SUPPORTING                STORAGE STACKS                    Abstract A system in which a device or machine is con-trolled by instructions from a data processor is provided which minimizes main memory storage require-ments.  An interrupt service routine monitors the input to the processor received from the device in response to control instructions sent by the proces-sor.  The interrupt service routine monitors this response for exception conditions.  When an exception condition indicating that the device is no longer capable of fully carrying out processor instructions is received by the interrupt service routine, it activates an exception handler routine.  A primary memory storage stack normally supports the interrupt service routine.  However, upon the activation of the exception handler routine, this primary storage stack is switched to support the exception handler routine, and a secondary stack of significantly lower storage capacity is placed in support of the interrupt service routine which should have lower purported storage requirements during the active period of the exception handler routine.  This results in a substantial saving of main processor memory capacity which otherwise would have to be dedicated to the support of the two respective routines.

Abstract: ABSTRACT          Title: SPRINGS FOR HIGH SPECIFIC ENERGY STORAGE   A spring element (12) comprises a strip of fibre-reinforced plastics material formed as a zig-zag consisting of a plurality of limbs lying in substantially the same plane and joined  at their ends by reflex portions (l4).  The strip includes at least a proportion of fibres aligned in its generally longitudinal sense, sufficient to spread stress concentrations away from the reflex portions, in use.  The ratio of the limb length to the radius of the reflex portions is desirably in the range 0.2 to 200, preferably 0.5 to 30, and this leads to an extremely compact spring.          Several elements (12) can be assembled together, possibly in different planes (eg Fig 6) to produce a spring assembly whose spring rates in different modes of deflection are easily controlled.  The spring elements (12) may include elastomer either as blocks (17) in the reflex portions (14) or as layers interleaved with fibre reinforced plastics layers (eg Fig 7).  The elastomer and plastics materials can be cured in mutual contact, to provide cross-linking between them.

Abstract: ABSTRACT   The arrangement for covering over a gap in a roadway has bars running across the roadway. The bars are supported by transverse beams spanning the gap obliquely and which are supported at their ends in joint gap edge structures in such a way that the ends of the beams are able to slide and swivel in relation to the edge structures. The bars are carried on the beams by friction-reducing bearing parts so that sliding of the bars is possible. The bars have openings through the structure thereof (as for example holes in the bar itself or in a frame fixed thereto) to take up the beams and the bearing parts are adapted to allow sliding without swiveling between each bearing part and the associated beam and to allow swiveling between the bearing part and a bar joined thereto. The bearings are made of elastically yielding material and each have at least one bearing body. To ensure efficient transmission of horizontal forces by the bearing bodies to the transverse beams with only a small pre-loading effect (to stop the bearing bodies being lifted clear of the transverse beams by tilting moments) the bearing bodies are shaped generally as blocks and run in respective grooves of the transverse beams.

Abstract: ABSTRACT     A firing assembly for a hard target penetrating warhead is described.  The firing assembly includes a safety and arming device with a truncated rotor that is normally retained in a safety position by its setback weight.  On acceleration, the setback weight releases the rotor for rotation into a firing position where a pyrotechnical train carried by the rotor is aligned with the firing pin.  To prevent over penetration of the pyrotechnical train by the firing pin on high deceleration, the firing pin has a striker with a radial flange that is captive in a chamber in the striker carrier.  To prevent retrograde rotation of the rotor to its safety position or high deceleration of the warhead, such as in penetrating a hard target, the bore in the rotor accommodating the pyrotechnical train is chamfered at the entrance end to provide a camming surface that can be engaged by a tapered face on the front of the firing pin.  This allows the firing pin to cam the rotor back into position when it has become displaced.  The rotor itself is supported in place by a support block engaging the front face of the rotor.

Abstract: ABSTRACT           A drywall tape applicator includes a -tubular handle and a unitary cast head attached to the handle. The head has a pair of spaced side walls and a roller at the free end thereof. A pair of discs, each mounted on a stub shaft, is spring-mounted for rotation between the side walls so that they can be easily separated for replacement of a tape roll therebetween while the spring force helps retain the tape roll firmly in place between the discs.  A spring-loaded knife assembly atop the head is connected to a trigger mechanism partly located in the tubular handle.  Tape on a roll held between the discs is fed over the roller and applied to a drywall joint by moving the applicator so that the roller can release tape to the joint.  At the end of the joint, the trigger mechanism is operated so that the knife can cut the tape, The applicator is light in weight for easy maneuverability and it is very efficient with respect to tape replacement,
