Title: Self-tensioning ribbon transport system
Inventor: GRAHAM JOHN FLETCHER
IPC: B41J35/08
Filed: 1983-12-01
Abstract: In a reel-(10) to-reel (14) ribbon (12) drive, the payout reel (10) is an idler reel rotating a shaft (22). The shaft (22) has a helical spring assembly (30) coaxial thereon. The spring assembly (30) comprises an energy storage spring (44) of diameter greater than that of the shaft (22) with a first end fixed to the base plate (24) of the transport at (32), and a helical spring brake (48) of lesser diameter than the shaft (22) for opposing the rotation of the shaft (22). As ribbon is drawn from the payout reel (10), the energy storage spring (44) is unwound to provide opposing force until the helical spring brake (48) slides on the shaft (22) to provide ribbon tension-inducing opposition to the rotation of the shaft (22). When movement of the ribbon 12 ceases, the energy storage spring (44) counter-rotates the shaft (22) to take up any slack ribbon (12), and to maintain tension in the ribbon (12). An optical sensor (36) senses when a flag (34) moves to an extremity of position indicatively of there being a breakage in the ribbon (12) or no ribbon on the payout spindle (20). <IMAGE>

Title: Removing manhole covers
Inventor: NAYLER ANTHONY ROLAND
IPC: B66F19/00
Filed: 1985-01-31

A screw and nut mechanism associated with one of the feet is then operated to raise a connecting beam (10) relative to that foot and so exert an upward force on the cover at a single position near to one side of the frame. <IMAGE>
Patent GB-2154525-A (GB)
Title: Transverse steering arrangement for track-guidable vehicles
Inventor: MEHREN HERBERT
IPC: B62D1/26
Filed: 1985-02-15
Abstract: A transverse steering arrangement for track-guidable vehicles is described in which the vehicle wheels (2) of at least the steerable axes are associated with supporting arms (4), which extend around each wheel and which are mounted in a constant position relative to the wheel, and with guide rollers (5) mounted on the supporting arms (4). To achieve a maximum degree of ground clearance below the supporting arm (4) when the transverse guide roller (5) is retracted, and to ensure also that extreme steering angles of the wheels (2) are not obstructed by the transverse steering arrangement, the guide roller (5) is mounted on a roller holder (9) so that it can be pivoted inwards and upwards behind the contour of the vehicle. The pivot axle (10) is arranged in the area of the bottom edge (24) of the supporting arm (4) and, in the transverse direction, has spacing approximately equal to the radius of the guide roller diameter from its rotary axle in an inward direction. With the pivot axle (10) arranged in the low position, the stops (12, Figures 2) can be arranged above this axle and its components do not limit the ground clearance because they project beyond the supporting arm in a downward direction. Space optimization is also achieved practically on the transverse steering arrangement in that the support arm (14) is formed of an open profile enclosing a hollow space, and a control element (21, Figure 2) which is remote from the roller holder (9), is arranged at least partially inside the supporting arm (4) together with the control mechanism (14, 15, 16). <IMAGE>

Patent GB-2198674-A (GB)
Title: Resistance welding apparatus
Inventor: BOYD ANDREW JAMES
IPC: B23K11/06
Filed: 1986-12-17
Abstract: Apparatus for resistance welding an elongate seam in a tubular article, comprises a first electrode wheel 1 outside the article, a second electrode 2 inside the article and a continuous electrode wire arranged to pass over the electrodes to provide surfaces of contact between the electrodes and seam material. The second electrode has a stationary block 6 having a guide surface of like curvature to that of the outer electrode wheel 1 so that the contact arcs of wire passing over the guide surface with the seam material is substantially equal to the contact area of wire passing over the external wheel 1. The use of this stationary inner electrode improves the weld geometry and permits welding of can bodies of relatively smaller diameter without use of mercury contact bearings.

Title: Thermoset molding compositions
Inventor: TSAI CHUNG-CHIEH
IPC: C08G18/66
Filed: 1989-05-31
Abstract: A storage stable blend of a long chain polyol and a short chain diol wherein the diol is present in an amount whereby the diol and polyol form an incompatible blend, is rendered storage stable by the addition of a compatibilizing amount of an ethylenically unsatured esterol. Alternatively, the compatibilizing agent comprises an adduct of the ethylenically unsaturated esterol and a polyol, e.g. glycol. The storage stable blends find utility in making rigid, tough RIM polyurethane parts. The polyol may be a polyoxyalkylene polyol having a molecular weight of 1000 to 20,000 and the diol may be a C2-C8- alkylene glycol. The esterol may be one prepared by the catalytically induced addition reaction of maleic anhydride or a mixture of maleic anhydride and phthalic anhydride with a lower alkylene oxide in the presence of acrylic or methacrylic acid as initiator, or it may be a simple hydroxy acrylate or methacrylate monomer, e.g. 2-hydroxyethyl(meth)-acrylate.

Title: Easy-open package and method of forming the same
Inventor: BONGIANA ANDREA P
IPC: B65B11/50
Filed: 1989-08-29
Abstract: An easy-open pack comprises a tray 5 supporting a product on one side and having its reverse side covered by a multi-layer first film 1 The product is held on the tray 5 by a second film 6. The first film 1 is bonded to the second film 6 over a portion of the films projecting laterally outwardly beyond the rim of the tray 5. The multi-layer structure of the first film 1 has a bond 4 of low bond strength between a thin upper part 3 and a relatively thicker lower part 2 thereof. Thus the second film 6 and the upper portion 3 of the first film 1 can be delaminated from the remainder of the first film 1 and can be ruptured by penetration of the upper portion 3 by the corner of the rim of the tray 5. This delamination is assisted by a cut 7 in the bottom film extending diagonally across a corner of the pack.

Title: A heating and cooling system with oscillation prevention
Inventor: MEHTA VINAY
IPC: G05D23/20
Filed: 1989-10-03
Abstract: A programmable thermostat for an air conditioning system having a heating system and a cooling system includes a sensor for sensing the ambient temperature, a timer for generating the current time of day, a memory for storing a plurality of program times, and a heating and a cooling control temperature corresponding to each program time. The memory also stores a first temperature span associated with the heating control temperatures and a second temperature span associated with the cooling control temperatures. The programmable thermostat controls the on/off state of the heating and cooling systems in response to (1) a comparison of the current time of day with the program times and (2) a comparison of the current ambient temperature with the current first and second temperature spans. These comparisons generate a switching control signal for controlling the on/off states of the heating and cooling systems. An alternation controller includes a first adjustor for adjusting the first temperature span prior to a changeover from the cooling system to the heating system. A second adjustor adjusts the second temperature span prior to the change-over from the heating system to the cooling system. Cycling of the air conditioning system between the heating system and the cooling system is thereby prevented if the heating control temperature is near the cooling control temperature.
