Filed: 1952-12-18
Abstract: 744,410. Switches held set and freed mechanically. RELY-A-BELL BURGLAR & FIRE ALARM CO., Ltd. March 17, 1954 [Dec. 18, 1952], No. 32152/52. Class 38(5) [Also in Group XXXVIII] An electric switch, forming part of a theft alarm, comprises a pair of contacts 13 which are closed by the passage of a stud 12 attached to a rod 4 projecting from a casing 3. The rod 4 is spring-urged outwardly and is so associated with further mechanism that on pressing the rod into the casing, for example by closing a wardrobe door, the mechanism is set and the subsequent release of the rod, for example by opening the door causes the contact 13 to be closed and the alarm operated. A key operating controlling device is provided; before the mechanism is set the key must be turned to the "On" position and in order to stop the alarm, once it has been operated, the key.must be returned to the "Off" position. The key operates a bolt 11, shown in section in the Figures, which when the key is turned to the "On" position moves to a ,position where it can engage with a plate 5 pivoted upon the rod 4. Upon depression of the rod 4, the sloping edge 14 of the plate 5 rides upon the bolt 11, thus turning the plate anticlockwise, until the position shown in Fig. 2 is reached after which the plate falls back so that the cage 15 engages the top of the bolt 11. The mechanism is now set and upon releasing the rod 4, the rod comes out a, short distance, whereupon the slot 16 engages the bolt 11 and further movement of the rod 4 in either direction is prevented. In this position the stud 12 engages the contacts 13 to close them and complete the alarm circuit. To release the mechanism, the key is turned to the "Off" position, whereby the bolt 11 is withdrawn out of engagement with the plate 5. It will be seen that during the setting operation the stud 12 will momentarily close the contacts 13; this causes the alarm to be operated for a short time and gives an indication that the apparatus is functioning, correctly.

Title: Improvements relating to the production of moulded boards or like elements
IPC: B27N3/18
Filed: 1955-11-16
Abstract: 796,636. Moulding resin-fibre boards. DRAISWERKE GES. Nov. 16, 1955 [Feb. 1, 1955], No. 32809/55. Class 87(2). The fibrous filler material, e.g., wood chips, is heated in a drier 1 to a temperature which approximates to the curing temperature of the thermosetting binder, e.g., 95‹C. for ureaformaldehyde synthetic resin. A device 3 feeds the filler material at a uniform rate to a mixer 2 in which liquid binder, suitably preheated, is atomised by preheated air and sprayed by a device 4 on the filler. Any other additives are also preheated. The mixture of filler and binder is then spread on a plate 8 by a spreader 6 comprising transversely moving screens. The plates 8 are advanced by a conveyer 9 to a press 10 having upper and lower heating means 10b, 10a. Since the binder and filler are both preheated to nearly the curing temperature a short time only in the press is necessary for the material to set, after which the press is opened and the plate 8 carrying the finished board is pushed out by the succeeding plate. The press is constructed for quick opening and closing and the conveyer 9, though shown as undivided, is constructed so that a more quickly moving section transports the plates and spread material from the mixer 2 to the press 10, heat loss during the passage being minimized by an insulated tunnel 11 with electrical heaters 12. Heat may also be conserved by constructing the press to be sealed during the pressing operation. The emptied plates 8 are lowered, and returned on another conveyer. Three-layered boards can be produced by the use of a separate drier and mixer 1a, 2a from which filler and binder mixture is fed to a separate spreader 6a which forms the lower layer, then the spreader 6 forms the middle layer with mixture from the drier and mixer 1, 2, and lastly the spreader 6a forms the top layer with mixture again supplied from the drier and mixer 1a, 2a. Specification 759,009 [Group II] is referred to.
