Abstract: 869,642. Tanks. BYGGFORBATTRING A.B. Feb. 13, 1958 [Feb. 13, 1957], No. 4804/58. Class 69 (1). In a method of erecting a vertical structure, or wall of edgewise erected plate-like elements, one positioned upon the other, the structure or wall being built-up element by element from below, the elements being joined by welding each section and lifted by means of one or more lifting jacks 8 (Fig. 5), the jack 8 is positioned at the centre of the structure to be erected and, during erection of the structure, permanently attached to the same part. As shown, a scaffold pole 1 is positioned centrally within a cavity in a rock. Tension adjustment devices 4, 5 are provided at the ends of the pole 1. At each side of the cavity staywires 10 are detachably fixed at 12 to one of a number of anchorage pins 11 secured to the rock face. A tension adjustment device 13 is incorporated in each of the stays 10. The roof 14 of the tank includes a number of bars 7 which are connected at their upper ends to a collar 6 mounted on the pole 1 on a ball-race so that it may be freely rotated about pole 1. One or more lift jacks 8 are positioned on the pole 1 to act on the collar 6 to lift this and hence the roof 14 up the pole, the jacks themselves climbing up the pole 1 as the collar 6 is lifted. A first annular section 20 comprising plate elements 16 to 19 is attached to the outer edge of the roof 14 and when the first section has been completed a second annular section is attached to the bottom of the first section 20, preferably by welding. A rotating device 31 is positioned near the entrance 15 to the rock cavity to engage with adjacent elements of the tank whereby in the course of erection of each section the tank may be slowly rotated about the central pole 1 to bring that part of the wall, next to be built up by means of a plate element, opposite the erection point. Instead of rotating the tank, a trolley 32 (Fig. 8) may be rotated about the pole 1, elements such as 35 being loaded on to the trolley which is rotated until it reaches a suitable position for welding the next element in place. In a further modification, the single pole 1 is replaced by a set of poles placed in the centre of the construction.

[Class 102 (i)] [Also in Group XXVI] A hydraulic brake pump comprises a hollow cylindrical or like body part a which is divided internally by a partition f to form a pump chamber g and a sealing chamber h, and which is mounted on a vehicle in an inclined position with the pump chamber at its lower end, and a plunger j extending completely through the sealing chamber and operated, against the action of a helical spring n in the sealing chamber, by hand or foot pressure applied to its outer end k. The pump is mounted in resilient bushes e and the plunger slides through glands m, the upper gland and the upper end of the plunger preferably being of non-circular crosssection to prevent relative rotation. The liquid in the sealing chamber is the same as that in the pump chamber, it serves to lubricate the plunger and spring, and it may be introduced through a side aperture s which may be connected to a supply reservoir. This liquid also may be utilized to replenish the pump chamber g, in which case the lower end of the plunger may be made hollow and provided with a side hole q. In the event of an undue pressure fall in the pump chamber, communication between the chambers g, h is re-established by means of a passage r and spring-loaded valve s within the plunger, as shown, or in the partition f. Alternatively, the pump chamber may be connected through a non-return valve to a separate supply reservoir. The plunger may consist of two parts which may be so interconnected as to allow limited axial relative movement.

The information may be analog data transmitted in pulse width form or digital data in binary form. As described the system is mounted on a vehicle and includes a master station at which is located the master clock, a stereo unit 44 with two transmitters 46, 48 and an array of control buttons 40 and transmitter 42. A computer 32 is also coupled to the line 12 by a transmitter 36 and receiver 34. The stations may include lamps 16 controlled by receivers 18 and speakers 22 with which are associated on/off switches 26 and selectors 28. The master clock unit (Fig. 4, not shown) generates a long synchronizing pulse of "1" potential followed by a short pulse of 0 potential then a chain of time slot start and stop elements of "1" and "0" potential each separated by an intervening period in which the master clock unit drives the line to one potential or the other depending on the direction in which the line is being driven by a transmitting unit. Fig. 5 shows a transmitter station. The equipment shown in upper portion of the diagram is provided at every station and includes a threshold detector (Transistors Q22-Q24 and Zener 22) which steps a time slot counter 80 and feeds a single shot circuit (Q25-Q26) which responds to the long duration of a synchronzing pulse and resets the counter to zero. The counter steps for each start pulse and at every time slot except that associated with that transmitter station enables a transistor Q30 preventing a transistor Q31 from conducting. During the allotted time slot transistor Q31 conducts or not depending on whether the data bit as set by switch DS is "0" or "1" or conducts for a portion of the time slot characteristic of an analog input at 87 if switch DS is set to the analog position 86. It is stated that more than one station may use a single time slot, the signals being combined in OR gates and that in this case the switches S also have a centre position.
