Abstract: A modular telephone housing 12 adapted for structurally and electrically coupling to other like modular telephone housings. The housing includes two tapered ribs 60 and 62 disposed at one end thereof, and two corresponding tapered grooves 104 and 106 disposed at an opposite end thereof for mating with the tapered ribs of an adjacent modular telephone housing. A male connector 18 includes a plate 34 coupling to one end of a flat cable 16, a resilient backing strip 44 between the plate and the contact strip, and two alignment pins 46 and 48. A female connector 20 includes a plate 74 coupled to the other end of the flat cable, and two alignment slots 82 and 84.

Abstract: An automatic inflation system for use as an emergency locating system which is activated by the severance of an initiator wire which in turn begins the operation of a transmitter and a timer. Following a period of time as determined by the timer, a pair of electrically activated pyrotechnic thrusters are actuated and cause the rupture of seals on a pair of compressed gas storage cylinders which in turn results in the inflation of two sections of a twin mast, raising a radio antenna and radar reflective material. A radio transmitter is also activated at the start of the time delay with an emergency locating signal broadcast from the antenna, after the mast is raised. This system provides improved means of locating missing equipment when searched for by radio search, radar search, and/or visual search.

Abstract: A reel for magnetic recording tape includes a hub having axially extending coaxial inner and outer rims joined by a radially extending web, and an intermediate ring on each side of the web extending axially outwardly of the web and a pair of opposed flanges. The flanges are attached to and extend radially outwardly of the respective hub intermediate rings and each flange includes hub support means cooperating with its respectively adjacent hub intermediate ring and the hub outer rim to assist the hub outer rim in resisting radially inward deflection.

Abstract: A marking gun for printing adhesive labels with pricing and the like having a printing head directly connected to an operating trigger for impressing the labels, a drive wheel is linked to the operation trigger by a ratchet and pawl assembly for incremental advancing of the labels carried on a backing tape, the tape being transported by radial drive teeth which engage perforations in the backing tape, separation of the labels from the tape being aided by a cam operated pressure shoe, and threading of the tape through the gun being aided by a retractable spring biased guide member which holds the backing tape against the drive wheel during operation, and guides the tape around the drive wheel during threading when retracted by a thumb trigger that projects from the casing of the marking gun.
