Abstract: 951,533. Blasting devices. HAYDEN-NILOS Ltd. Sept. 25, 1961 [Dec. 17, 1960], No. 43520/60. Heading F3A. Infusion equipment for blasting minerals has the outlet end of its bore 8 provided with a spring-loaded valve 13 seating at the mouth of the outlet which operates in opposition to the flow of water from the outlet. The equipment consists of an expansible tubular seal 1 which closely fits round a cylindrical core 2 the seal being constrained to the core at each end by caps 3 and 5. The cap 3 has a reduced portion 4 threaded for attachment to a pressure water supply and the cap 5 provides an outlet for the pressure water. The core has an interrupted bore the inlet end 6 of which terminates in a cross passage 7 extending to the periphery of the core, while the outlet bore 8 extends from a similar cross passage 9. In this form of the invention one end of a compression spring 12 fits into a bush 11 screwed into the outlet end of the cap, and the other end holds a ball valve 13 on a seating 14 at the outlet end of the bore 8. The valve serves as a relief valve to prevent the seal from bursting in the event of the application of the supply pressure before the equipment has been inserted into a hole and also the valve ensures that the pressure within the seal is greater than the pressure built up in the hole and thus the built-up pressure cannot eject the equipment from the hole. A bleed valve (not shown) may be provided in the water supply to the equipment. Specification 922,418 is referred to.

The message recording tape is wide and supported on guide rollers 23, 24, 25 with the magnetic head moved transversely across the width of the tape. Answering tape: Fig. 15. The “ inch wide answering tape 18 is wound several times around hub 19 and passes around pin 21 and pinch roller 20 and is housed in a frame 32 which is removably inserted in the machine assembly. The tape has an elongated slot which allows one revolution of the tape to be sensed by a feeler 56 which co-operates with a groove in guide 21 to operate microswitch 55 (see also Figs. 10-12). The co-operating head assembly 46 can be moved transversely of the tape by means of a manual control knob to define three tracks each carrying a different answering message. When the third track is used the machine is prevented from recording the callers message by means of abutment 93 which prevents the capstan arm 62 rotating clockwise to drive the message recording tape. Message recording tape: Fig. 21. This 3 inch wide tape 22 is contained in casing I which supports a driving drum 26, fixed guide rollers 23, 24 and a tensioning guide roller 25. This tape is also formed with an elongated slot which is used to signal the completion of one revolution of the tape. Co-operating with the tape 22 is magnetic head 219 which is driven transversely across the tape by means of a screw which itself is driven through gearing from driving drum 26. The driving drum is coated with a rubber lining to assist driving the tape. The magnetic head has a recording/ reproducing core 0À5 mm. wide and an erase core 0À6 mm. wide and for each revolution of the screw moves by 0À6 mm. during which time the tape 22 travels half its length. A gear is then disengaged between the driving drum and the screw and the tape completes one revolution. A timing arrangement including a clutch ensures that one message cannot be prolonged for more than five complete revolutions of the tape. The position of the recording head is indicated by pointer 6 on scale 244 and provision is made for recording up to 20 calls. An automatic cut out prevents the machine operating if a full recording could not be made on the 20th call. Lever 4 is used for manually positioning the magnetic head. Operation of the machine is controlled by pushbuttons which provide for replaying the answering announcement and the recorded messages. An internal speaker is provided as well as sockets for a microphone and earpiece. Insertion of the microphone in its socket arranges the circuitry to rewind the answering announcement when the respective reply button is pressed.
