Title: Rotary files or classifiers
IPC: A47B63/06
Filed: 1970-04-22
Abstract: 1311207 Rotary rack stands J FEVRE 22 April 1970 19207/70 Heading A4H [Also in Division B6] A device for holding letter files, loose-leaf binders, cards or tickets comprises a circular support 3 mounted on an axle 1 rotatable about a vertical axis, and rods 8 attached at their inner ends to a circular plate 7 spaced above the support 3, the binders, etc., P being placed between pairs of rods 8 with their inner ends abutting the periphery of the plate 7. Tubular spacers 6 separate the plate 7 from the support 3 and also from an upper plate 16 which may be approximately of the same size as the support 3, or may be smaller as shown. In the latter case, a larger upper plate 17 also is provided having an outer rim 20, the spindle 19 of the plate 17 having a pin and cam slot connection with the hollow axle 1 whereby by a rotary movement the plate 17 can be raised to raise the rim 20 and allow removal of the files P or lowered to prevent removal of the files. A device 21 is provided to lock the plate 17 in its lowered position. As shown the outer end of each rod 8 is secured near the periphery of the support, and the end is bowed to serve as gripping means for rotating the device. In another form, however, Figs. 3 and 4 (not shown), straight radial rods are used instead of the bent rods 8, and tubular members extend between the support 3 and an upper plate near the periphery of the support, the binders such as P being inserted between a pair of tubular members into the space between two radial rods. According to another construction Figs. 5 and 6 (not shown), a plate corresponding to the plate 7, Fig. 7, is polygonal in shape with curved sides, and rods similar to the rods 8 extend outwardly from the corners of the plate. A device 6, 14, 15, Fig. 8, similar to the parts 6, 7, 8, shown in Fig.7, may be mounted on a support 27 rotatable about the axle 1 and situated above another rotatable section comprising a number of shelved compartments 23 spaced from one another around the periphery of a support 3 and used for holding e.g. railway tickets. The support 27 and another support 26 carry a number of glass sheets 29 corresponding to the number of compartments 23, so that by rotating the support 27 the openings to the compartments may be exposed or may be covered by the sheets 29 to prevent access to the compartments.

Abstract: 1325444 Plate heat exchangers DUNLOP HOLDINGS Ltd 8 July 1970 [11 July 1969] 33053/70 Heading F4S [Also in Division B1] A hollow plate structure intended for use as a heat-exchange element comprises a pair of spaced-apart plates 2, 3 sealed together at their edges 4 and having flanged apertures 10 therein, aligned in pairs with the flanges 18, 19 thereof of each pair extending towards one another as tubular projections of circular cross-section and in interfitting association. In one form (Figs. 1, 2 and 4) the interfitting flanges are sealed together so that the space 5 within the hollow plate is isolated from the exterior. Water may be circulated through the hollow plate, e.g. via ducting 8, 9, to be heated by burner gases flowing over the plate exterior and through the tubular apertures therein. Boilers are described (Figs. 7, 8, 9) in which a number of such elements (45 or 67) are heated by burners (44 or 66) of the kind described in Specification 1,325,443. Fig. 6 shows a further form in which finned tubes 31 extend through the apertures 32 whereby heat may be exchanged between three fluids. The intermediate fluid, e.g. air, may flow through the apertures as shown by the arrows A or transversely to the tubes in the space between adjacent elements 30. In another form (not illustrated) the flanges are interfitted so as to permit fluid leakage from the interior of the hollow plate whereby a gas or liquid in the hollow plate will be carried away and in admixture with a stream of air flowing over the hollow plate. Such a device may be used as an evaporator for liquid nitrogen to provide a stream of cold gas for use in the quickfreezing of food. The device may also be used as an evaporator for water when utilized as a temperature reducing and humidifying element in an air conditioning system. Reference has been directed by the Comptroller to Specification 1,183,759.

Abstract: 1335707 Theft alarms I J YOUNG (INSTALLATIONS) Ltd 16 Nov 1971 [19 Aug 1970] 39943/70 Heading G4N A theft alarm system comprises a closed container housing a mains transformer T1 feeding a rectifier REC1 which supplies power to a relay RL1 via a pair of sockets SK2, SK4. Socket SK4 is connected to a switch contained in a pedestal so that the switch is opened by removing an article from the pedestal. As described, the system is reset by operating pushbutton SW2 which energizes relay RL1 via a breakable flexible conductor linking SK2 and the pedestal switch connected to SK4. The relay RL1 is held energized by contacts 4 and 5 but released by rupture of the flexible conductor or removal of the article from the pedestal, so as to operate an alarm bell BL and indicator lamp PL2. A further buzzer is operated by relay RL2 in the event of supply failure. Fig. 7 shows an arrangement having three switches S contained in one or more pedestals, each switch being set to its upper position when an article(s) is removed from the pedestal. The momentary open circuit thus releases relay RL1 and sounds the alarm bell BL. A further alarm lamp BL3 is energized via isolating diodes D. The alarm can be inhibited by an authorized person using a key comprising a magnet to operate a read contact unit 22 and a probe to close contacts 20.  Modifications.-Relay RL1 may be replaced by a thyristor whilst the bell BL may be replaced by a transistorized oscillator emitting one frequency for power failure and a second frequency in response to theft.

Title: Fire alarm monitor

Filed: 1971-05-25
Abstract: 1343819 Fire alarms WALTER KIDDE CO Ltd 15 Feb 1972 [25 May 1971] 17066/71 Heading G4N In an alarm system having a plurality of units 3, 4 each having a normally open contact AA, BB, connected across a line 1 and closed in response to an unwanted condition and a normally closed contact A, B, connected in series with line 1 and opened in response to a fault in the units 3, 4, at least one of the normally closed contacts B is bridged by a circuit including a fault indicator 11 and having an impedance such that operation of normally opened contacts, such as AA, will still be detected despite opening of contact B. As described, the standing current in line 1, as determined by resistor 2, is sufficient to maintain transistor 7 conductive and fault relay RL1 energized. In the event of a fire, one of contacts AA, BB, closes so as to energize alarm relay RL2, which is held in by contact 5 and operates bells or a lamp. A fault in one of alarm units 4 causes opening of the normally closed contact B which would prevent detection of the closure of subsequent normally open contacts such as AA. A circuit comprising thyristor 8 and resistor 9 is therefore included which operates an indicator lamp 11 when contact B opens. Resistor 9 has such a value that the opening of contacts B will be detected by the de-energization of transistor 7 and fault relay RL1, but the alarm relay RL2 will still be operated in the event of closure of contact AA. Diode 10 protects the gate circuit of thyristor 8. Thyristor 8 may be replaced by a reed relay or Darlington pair.
