Title: Improvements in or relating to systems for weighing loads
IPC: G01G19/413
Filed: 1960-02-19
Abstract: 943,087. Weighing apparatus. HOBART MANUFACTURING CO. Feb. 19,1960 [Feb. 19, 1959], No. 5984/60. Heading G1W. A weighing system which is set for use by the operation of a manual setting control and which includes a weighing mechanism moving at each weighing between a pre-set tare-discounting noload position and a net-load-indicating position, has means providing a signal of the operation of the setting control and a manually operable tare adjusting device the use of which automatically cancels this signal. Preferably the signal operation is automatically accompanied by the operation of means which prevent the use of the system until the signal has been cancelled. The tare adjusting means comprises a knob 30 which, when pushed against the spring 50, causes a slot in a sleeve 44 to engage a pin on a threaded shaft 31. Rotation of this shaft causes lever 35 to rock about its pivot 36 and adjust the tension in a spring resistant 40 of the weighing mechanism. The contacts 61, 62 of the switch 60 are made when the sleeve 44 has been advanced sufficiently to engage the pin on shaft 31. The invention is described with reference to electrically powered systems in which the load is weighed, has its value computed and a printed ticket issued. In such systems, the signal is automatically given not only when the apparatus is first set up but also whenever the settings of any of the associated elements of the system are changed. The signal is a lamp which is illuminated by the closure of a relay contact, and another contact of the same relay may control the said means for preventing operation of the system. The latter contact may either interrupt the power supply of the apparatus or cause the energization of a solenoid to effect movement of a stop into the path of the weighing mechanism. The switch 60 operated during taring is arranged to de-energize this relay. Once the initial setting and associated tare adjustment have been performed, the system may be used to perform a succession of like weighings without further adjustment. If however any of the setting means are changed e.g. because the nature of the loads to be weighed in further weighings is different, the signal is once again given so that the possible need for tare re-adjustment will not be overlooked. Specifications 695, 635, 808; 235 and 886, 876 are referred to.

Title: Improvements in or relating to apparatus for controlling the supply of pressure medium
IPC: E21D15/51
Filed: 1960-02-23
Abstract: 889,261. Hydraulic apparatus. BOSCH G.m.b.H., ROBERT. Feb. 23, 1960 [Feb. 26, 1959], No. 6290/60. Class 69 (2). Apparatus for controlliing the supply of pressure medium to a device 16, such as an hydraulic motor or pit prop, comprises a casing 7 having an inlet 6 for the pressure medium, a first outlet 9 for connection to the device and a second outlet 24 for connection to a reservoir 3, and a member 45 which controls the outlets and is biased against the pressure of the pressure medium supplied to the device, the bias urging the control member to a position wherein the inlet is connected to the second outlet and the pressure of the pressure medium serving, down to a predetermined minimum pressure, to hold the control member against the bias in a position wherein the inlet is connected to the first outlet. The control member consists of a spool 45 which can be moved manually by actuation of a knob 53 displacing a rod 48 contacting the end of the spool against the bias of a spring 57 to a left-hand position determined by a rod 59 so that the pressure medium from a pump 1 passes from the inlet 6 to the first outlet 9 which is connected to a pressurecontrol valve 10. A line 14 from the valve leads to a device 16, a pressure storage tank 18 and an inlet 20 in the casing. The pressure at the inlet acts on the end of the rod 48 and is sufficient to overcome the bias of the spring and maintain the spool in its left-hand position. In the event of the pressure supplied to the device 16 being reduced, for example by fracture of the pipe 14, the bias of the spring moves the spool to its right-hand position to connect the inlet 6 to the second outlet 24 connected to the reservoir. A bore 47 connects both ends of the spool to the reservoir.
