Title: Expansible joint for structural members
IPC: E01D19/06
Filed: 1977-02-28
Abstract: Expansion joints which are subjected to traffic loads are often designed with metal structures with elastomeric expansion strips. With relatively large widths, such expansion joints are subdivided into part-joints by metal supporting bars. In the case of the invention, grooves (15, 16) in which the expansion strips (20) are held are arranged on the gap-side delimiting surfaces (14) of the edge profile carriers (1). Since the edge profile carriers (1) delimit a trapezoidal intermediate space, the conflicting requirements:   a) as narrow a gap as possible in the area of the carriageway between the metal parts,   b) exchangeability of the elastic expansion strips (20), and c) the largest possible expansion area of the elastic strip or strips (20) can be overcome in an optimum manner. With large joint widths, supporting bars can be arranged to give a plurality of trapezoidal intermediate spaces with grooves (15, 16) for holding the expansion strips. The structure is suitable for expansion joints on constructions of any size, in particular for road bridges. <IMAGE>

Abstract: 920,424. Packaging; forming cartons. METAL BOX CO. Ltd. Feb: 15, 1961 [March 11, 1960], No. 8747/60. Classes 18 and 94(1).  Box blanks for forming open-ended boxes, Fig. 1, are fed from a magazine at stage 31 Fig. 4, on to an intermittently moving conveyer and are erected to tubular form as in Fig. 12 during the feeding, in which form they are fed to a filling stage 33, at which an article is pushed thereinto by conveyer 85, and then to a folding station 35 at which the side flaps 5. which partly cover the ends, are folded inwards, and secured. In Fig. 12 the box has flaps 9, 10 in addition to the side flaps 5, which latter have tabs 7 which are secured in slots 8 in the top and bottom. The collapsed box blanks in magazine 31 are fed downwardly on to the conveyer 13 by suction carriers 37, Fig. 9, on a reciprocating carriage 42 which is actuated through a bell-crank member 45 by a reciprocating plate 49. In moving downward into position between supports 24 on the conveyer, the blanks are set up to the condition of Fig. 12 by guides 62, Fig. 9. The carrier 37 may be rendered inoperative by de-energization of a solenoid 44, Fig. 9, which allows lever 45 to swing out of contact with the reciprocating member 49. At stage 70, Fig. 4 pairs of hooks engage the infolded tabs 6 and pull them outwardly into the plane of the side flaps 5. At the filling stage 33 an article, such as a batch of eggs 11, Fig. 2 held by connectors 12, is fed forwardly by chain operated pushers 84, Fig. 16, and pushed into the box through a guide funnel 99 which is reciprocated into the box opening by lever 100. A stop 82, operated from the tab lifting mechanism 70 Fig. 4, locates the box during filling. At the folding stage 35 the flaps 9, 10, are first folded inwards by rotating members 104, 105, Fig. 18, the side flaps 5 are folded inwards and tabs 6 bent down against slots 8 by rotating rollers 116, 115, Fig. 20, and the tabs are pushed through the slots 8 by reciprocating fingers 130, 131, Fig. 18. In a modification the flaps 9, 10, are replaced by locating means which formed in the sides 1, 2 by score lines and are pushed inwards.

Title: Improved Pulse Analyzing Apparatus and System
IPC: H03K5/1532
Filed: 1967-02-23
Abstract: 1,160,026. Voltage measurement; electrophysical measurement. COULTER ELECTRONICS Ltd. Feb.23, 1967 [Feb. 23, 1966; Feb. 7, 1967], No. 8791/67. Headings G1N and G1U. [Also in Division H3] In apparatus for determining the pulse amplitude at the centre of the pulse, the pulse is integrated in such manner that the curve of the integrated pulse is equal to that of the input pulse at the time centre of the input pulse, a gate is arranged to be opened when the two curves reach equality at the time centre, said gate passing a signal, equal to the pulse amplitude at the time centre, for a fixed time period. Detecting particles in fluids. The invention is applicable to particle detection systems of the type described in Specification 722, 418, Fig. 1. (not shown) relates to the isopotential lines surrounding an aperture in a sapphire wafer separating two liquid-containing chambers. It is shown that the shape of the current pulse produced between the two liquids when a particle of given size passes through the aperture is a function of the path of the particle relative to the axis of the aperture; the peak value of the current pulse only coinciding with its time centre when the pulse travels along the axis. It is shown that the pulse magnitude at its time centre is constant for a given sized particle, irrespective of the path through the aperture, hence when pulses are manipulated by the system described below, a more accurate determination of particle size is obtained. Reference is made to the use of a long aperture followed by a low pass filter or to the rounding of the contours of the aperture so as to provide more uniform current density. Such methods are, however, stated to be less advantageous than the system described below. Determination of pulse amplitude at the time centre. As shown in Fig. 2, pulses 52, Fig. 3, from 40 (derived from the current through an aperture in a wafer separating two conductive liquids) are passed via a gate 68 to an integrator 74 which provides a curve 76, Fig. 3, adjusted to become equal to that of the curve 52 at a time approximately equal to its time centre. A monostable multi-vibrator 114 is triggered by circuits 82,104,108 when the instantaneous values of the integrated pulse 76 and input pulse 52 are equal i.e. at substantially the time centre of the input pulse 52. The output of 114 opens a gate 120 which passes the centre value 124 of the pulse 52 to classification circuits 134 for a short period. Noise is inhibited by a threshold circuit 56, feeding a leading edge detector 140 and bi-stable circuit 66. This arrangement ensures that only pulses the amplitude of which exceeds the threshold of 56 are passed by the electronic switch 68. Circuits 56,66,74 are reset by the trailing edge of the pulse from 114. In Figs. 5, 6 (not shown) the mono-stable multivibrator 114 provides a longer duration pulse which is used to gate the output of the integrator which, in this case, is arranged to remain constant at the value reached at the time centre of the input pulse.
