Title: Improvements in or relating to burglar alarm systems
IPC: H04M11/04
Filed: 1958-03-06
Abstract: 852,193. Electric burglar alarm systems. LANDER, A. June 8, 1959 [March 6, 1958], No. 3901/58. Class 118 (1). A burglar alarm system associated with a telephone circuit apparatus, incorporating a time delay device in the alarm bell circuit, includes a relay having two windings, one in a telephone circuit, and two sets of contacts, one of which by-passes the delay device when the relay is energized. In the embodiment shown, an incoming telephone call over lines 4 energizes relay winding X, completing the circuit to winding Y via contact X1. Contact Y1 closes, by-passing the delay device TDD, and contact Y2 closes, completing a circuit to the thermal delay THH. After the delay determined by THH, contact THC opens, and if during this time the incoming call has ceased, the circuit restores to normal. The alarm is initiated by a burglar causing a relay (not shown) to operate closing contacts C2 and G1. This completes the circuit to relay B either through delay circuit TDD or through contact Y1, depending on whether an incoming call is being received or not. Operation of B closes contact B2 to energize alarm bell 7, and also closes self-hold contact B1.

Abstract: 778,496. Packaging-machines. KRAFT FOODS CO. Feb. 17 1953 [Feb. 28 1952], No. 4409/53. Class 94(1). [Also in Group V] In a machine for packaging food or other products, such as processed cheese, cream or margarine, a web 31, Fig. 1, of thermoplastic material is fed intermittently from a roll 62 to mechanism 24 which forms it into a series of interconnected open-topped containers 33, Fig. 3, which are supported and conveyed by transverse slats interconnecting spaced endless chains 116 driven intermittently through chain and sprocket gearing from a motor 71. The containers are filled in succession as they pass under mechanism 25, and a second web 41 of thermoplastic material is then fed by mechanism 26 under a guide plate 135, Fig. 10, into contact with the flanges 35 of the containers. A platform 142, carrying a resiliently-mounted recessed sealing member 152, is reciprocated vertically by an eccentric 144 to press the flanges of each container and the superposed portions of the web 41 against a steam pipe 42, thus sealing them together, and the completed packages 30, Fig. 14, are severed in succession from the webs by a knife 44 on the platform 142, co-operating with a fixed knife 45, and fall onto a delivery conveyer 46. Several webs 31 may be fed side-by-side and the various mechanisms duplicated to produce several packages simultaneously. The mechanism 24 (see also Group V) comprises one or more electric heating units 36 and recessed dies 38, Figs. 2 and 5, carried by a lower platform 37 reciprocable on guides 64 by a cam 74 on a driven shaft 67. An upper platform 40, reciprocable on the guides by an eccentric 83 on the shaft, carries a corresponding number of resiliently-mounted platens 101, each platen having a facing 102 of resilient material which seats on the flanges of the associated die and being held in position on a compressed-air pipe 97 by an apertured screw 98. Each web 31 passes through a slot 111 in a vertical flange of the associated platen. The timing of the cam and eccentric is such that the two platforms are moved towards one another while the webs are stationary to bring the heating units 36 into engagement therewith and to clamp the previously heated portions of the webs between the platens and dies. Compressed air is then admitted through the pipes 97 to stretch the heated portions of the webs into the dies, after which the platforms are moved apart to allow the webs to be drawn forward one step and the operations repeated. The dies are formed with passages 88 to allow the escape of air and a removable plate may be fitted at the bottom of each die to prevent the formation of air bubbles. The plates may be inscribed with advertising matter. Specifications 677,069 and 778,497 are referred to.
