Abstract: 1379570 Trailers; road vehicle couplings MARTIN FIALA KG 31 Dec 1971 [13 March 1971] 61037/71 Headings B7B and B7T A trailer 5 has a socket 6 into which a coupling tongue 9 of a tractor 1 can be inserted to provide a traction coupling between tractor and trailer on raising the tongue after its insertion into the socket, the socket 6 increasing in width from a position 21 inset from its mouth to its rear and being provided with means, e.g. 23, for centering the tongue 9 in the socket when the tongue is raised. The centering means may, as shown in Fig. 6, comprise projections 23 from the base of the socket or alternatively, Fig. 7, inclined parts 20 of the socket side walls which may join with horizontal parts of the socket walls as shown in full lines or with vertical parts of the socket walls as shown in dotted lines. The base of the socket 6 may slope downwardly towards the socket mouth as shown in Fig. 1 and the socket may increase in width from the position 21 to its mouth as shown in Fig. 6. The socket width at the position 21 may correspond to the width of the part of the tongue 9 which is located there when the tractor and trailer are coupled. The trailer may have a socket 6 at each end (Fig. 4, not shown). The tongue 9 may form part of a goose-neck 4 supported on a saddle plate 3 of the tractor 1, the plate 3 being carried on an arm 2 which can be pivoted to raise the tongue 9 and the goose-neck 4 being provided with a counter-balancing weight 11 serving to hold the tongue 9 horizontal when the tractor and trailer are not coupled. To prevent disengagement of the tongue 9 from the socket 6 the tongue may have a lug (24) on its upper surface engageable with a recess in the socket roof (Fig. 5, not shown) or a part-spherical projection (27) at its free end which engages a recess in the base of the socket (Fig. 8, not shown).

Patent GB-2017620-A (GB)
Title: Walking Beam Cooling Bed
IPC: B65G25/02
Filed: 1979-03-01
Abstract: An apparatus for transferring at least one elongate member includes fixed beams whose upper surfaces include a longitudinal array of identical convex curves. The apparatus also has movable beams whose upper surfaces define points which describe a closed path which intersects the upper surfaces of the fixed beams at the junction points of the curves in the ascending portion of the closed path, and which intersects the curves at a point downstream from their uppermost portions in the descending portion of the closed path. The elongate members which initially rest at the junctions of the curves of the fixed beams are therefore picked up by the moving beams during their ascent, and are subsequently deposited on the downstream portion of the adjacent downstream arc during the moving beams' descent. The square section elongate members rotate 90 degrees as they continue, under their own weight, to the junction immediately downstream from the initial junction. <IMAGE>

The upper ride bars form in part a support for the upper ends of the articles. A lower end of each article is in contact with and supported on an elongated vertically movable ride bar 338 positioned below the upper bars so as to maintain the articles in an inclined orientation. By reciprocating the lower ride bar, the articles are walked from the load station to the unload station where they may be accumulated and stored in a damage-resistant stacked condition ready for selective release as required. <IMAGE>

The hafnium compounds are efficient heat-radiators which allow the tube to run at a lower target temperature or with higher electron beam energy. Deposition by plasma spraying, sputtering, evaporation, vapour deposition, or spraying with a binder and sintering, are mentioned. Coating 48 may be 0.01 to 0.10 mms thick. <IMAGE>
Patent GB-2036810-A (GB)
Title: Process for Printing With Developing Dyes
IPC: D06P3/64
Filed: 1979-11-23
Abstract: A process for printing a material comprising cellulosic fibres with a developing dyestuff comprises impregnating the material with an alkaline liquor containing the coupling component for the dyestuff, and subsequently printing the material with a printing paste which has been prepared by combining two stock preparations, of which one contains sodium nitrite and a thickening agent and the other contains an acid, preferably selected from the range of medium strong to weak acids, especially an organic acid, and a thickening agent, and to one of which stock preparations, preferably the acid stock preparation, there has been added the amine component for the dyestuff. A known process wherein the sodium nitrite is applied via the impregnation liquor tends to produce nitrous gases, and a known alternative requires dissolving the amine in hydrochloric acid and subsequent buffering of the printing paste. The present invention avoids these disadvantages.

Title: Averaging thermometer
IPC: G01K3/04
Filed: 1980-08-05
Abstract: Improvements in or relating to temperature recorders. A problem with recordal of temperatures to produce an average for a given time period has been that the continuous temperature value has not been used. The invention converts the temperature to a current signal in a sensor (1) and then to a voltage (2). A voltage to frequency converter (3) produces a frequency pulse signal. An oscillator (5) signal is divided in a divider (6) to give a one day duration pulse which is divided (8) according to a selector (7). A second divider (9) divides the pulse signal by a related factor before counting in counter (10) and displaying the average temperature on a display (12) at the end of the time period. The invention finds use in energy conservation projects to monitor accurately the temperature average over several days. <IMAGE>

Title: Maintaining Pressure in Aircraft Tyres
IPC: B60C23/00
Filed: 1980-11-11
Abstract: An aircraft pneumatic tyre and wheel assembly has fixed thereto a pressurised reservoir of air which revolves with the wheel. The reservoir is connected (at 2) first to a pressure gauge 3 for checking by ground maintenance staff and then, by a passage normally closed by a piston 9, to the inner tube of the tyre (connected at 7). The passage remains closed until the pressure in the tyre falls below a certain limit, whereupon a sensing device 31-32 connected at 30 to the tyre inner tube operates to close electrical contacts 20,21 energising relay 15 which via linkage 13 displaces the piston 9 to open the passage and to allow the pressurised air in the reservoir to maintain pressure in the tyre. A gauge 27 in the cabin registers the pressure in the tyre and a warning light 26 draws the pilot's attention to the fact that the reservoir has been called into use. <IMAGE>
