Abstract: 1293354 Sensing rest or motion; recording- apparatus SUN OIL CO 13 Nov 1969 [15 Nov 1968(2)] 55527/69 Headings G1J and G1K [Also in Division E1] The operation of a wellbore surveying instrument, Fig. 1, which measures the direction (with respect to the magnetic field), and angle of slope of the wellbore, is initiated by means responsive to the absence of motion of the instrument. In one embodiment the motion sensor has a housing 26 which has roughened interior walls and is insulated at 28 from a base plug 27 having an upwardly projecting pivot member 29. When the instrument is stationary a ball inside the housing makes a continuous connection between the pivot member 29 and housing 26 to complete a circuit. Completion of the circuit starts an oscillator and counter and after a predetermined time operation of the instrument is initiated and a lamp circuit in the instrument is closed so that a photograph is taken of the reading of the surveying instrument. The counter also controls an electric motor to move the film 14 on another frame. Photographs are taken at intervals until movement of the instrument causes the ball to break the circuit. When this happens the film 14 is moved on to leave an unexposed frame to indicate completion of readings at this point. In another embodiment, Fig. 6 (not shown), a ball when moving in a housing due to movement of the instrument varies the magnetic field produced by a magnetic plug inserted in the housing and consequently produces an electric signal in a circuit. Cessation of the signal operates an oscillator and counter and after a predetermined time operation of the instrument is initiated and a lamp circuit is closed so that a photograph is taken on a single plate. In both embodiments a mercury switch closes a circuit from the power supply, which may be batteries or an above hole supply, only when the instrument is approximately vertical to prevent operation when the instrument is horizontal before insertion in the bore hole.

Patent GB-574763-A (GB)
Abstract: 574,763. Moulding-machines. BRIGGS MANUFACTURING CO. Feb. 16, 1944, Nos. 2896 and 2897. Convention dates, Jan. 29, 1943, and Nov. 1, 1943. [Class 87 (ii)] [Also in Group XXII] A machine for extracting a plaster or other mould from its flask 20 by means of a vacuum head 22 moved into contact therewith and then withdrawn, is arranged to ensure a reduction in speed of the head 22 towards the,mould as it begins to engage it. In the machine shown in Fig. 1, a previously extracted mould 21 is removed from the head 22, a charged flask 20, Fig. 5, with patterns 20a therein is fed in inverted position to guides 19 between the head and a magnetic chuck 23, and then a button 74 is pressed to energize a solenoid 48. This moves a valve 29 to connect the bottom of a cylinder 26 to pipe 30 supplied by pressure fluid by a pump 33 and an open valve 34 and to connect the top of the cylinder to the sump 31. The piston 25 in moving up brings an adjustable shoe 81 into contact with a switch 84 which it closes just before the head 21 engages the mould. The switch 84 causes a solenoid 55 to close the valve 34 so that the pipe 30 and hence the bottom of the cylinder 26 is supplied through an adjustable choke 36 only, thus causing the head 22 to move slowly, excess fluid being returned to the sump 31 through a relief valve 38. The switch. 84 also energizes the magnetic chuck 23, to hold the flask 20 away from the guides 19; and drives the motor of the vacuum pump 70 which is connected to the head 22 through a valve 63 and pipes 61, 60. When a reduction of pressure of e.g. ten inches of mercury has been reached; a vacuum-operated switch 73, connected to the head 22 by' a pipe 71, closes a circuit through a solenoid 47 and reverses the valve 29 and thus lowers the piston 25 and head 22 and extracts the mould 21. As the head moves down slowly, shoe 81 releases the switch 84 and the chuck 23 releases the the pump 70 stops, and the valve 34 opens so that piston 25 moves down rapidly. As it reaches its lowest position, an adjustable projection 90 closes a switch 94 for a moment causing a solenoid 67 to move the valve 63 so as to admit air to the head 22. This allows the mould 21 to be removed from the head and opens the switch 73, thus breaking the circuit to the solenoid 47 ready for the next cycle.
