Filed: 1970-09-02
Abstract: 1338375 Data transmission systems HONEYWELL Inc 2 Sept 1970 [6 Feb 1970] 17264/73 Divided out of 1328821 Heading G4H A data transmission system comprises a central control station 110 and a number of remote stations which receive messages from and transmit messages to the central station which includes a processor 120 for processing the information in the messages from the remote stations, at least some of the messages transmitted from at least one remote station including a data bit which conditions the processor to process the information received from other remote stations in a selectable predetermined manner. The system may be used to monitor building air conditioning apparatus and the remote stations at which a ventilation fan 126, an air flow sensor 124, temperature sensors 125, 130 and a fire detector 131 respectively are located, are connected in Groups I, II to respective transceivers 113. The central station may send a command message to a remote station such as station 1 in Group I to switch off the motor 123 controlling the fan. The message comprises a first part including the group address and a second part including the station address plus a "motor stop" bit. The central station also sends a scan message to the group so that each station reports its status to the central station. The reporting message from station 1 includes a "lock out" bit which informs the central station to disregard messages from certain other stations to prevent operation of alarm apparatus 122 at the central station. The messages from the other stations also include a "non-reporting" bit the value of which determines whether or not the central station regards or disregards the message from that particular remote station. For example, the command to switch off the fan causes a rise in temperature so that the message from the station 3 which includes the binary coded decimal value of the temperature also includes a "non-reporting" bit having a value which informs the central station that pre-determined temperature limits should be ignored so that the alarm is not operated unnecessarily.

[Class 20(ii)] Shuttering walls, built up from panels 14 having their horizontal edges formed with interengaging tongues and grooves, are spaced apart by sheet metal ties a having their ends shaped to engage between the horizontal panel joints. To dismantle the shuttering after casting, the upper panels are removed and the ends of the uppermost ties bent upwardly to allow the next lower panels to be removed. The ties may be protected by tubes to allow them to be withdrawn after casting. If the ties are to remain in the wall, they may be formed with lines of weakness so that they may be broken off adjacent to the wall. To strengthen the shuttering, waling members may be provided between the horizontal joints and extending across the vertical joints. The ties may be placed over the vertical joints and the vertical joints may be staggered. To stiffen the ties their middle parts may be embossed. Tongues stamped out of the ties may be bent up and over the waling members. When the ends of the ties are of such a thickness that they would materially open the joints between the panels, the edges of the panels are formed at intervals with depressions to receive the ends of the ties. The ends of the ties may be formed with down-turned flanges which engage the outer sides of the panels. Specification 616,526 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of ties 33, Fig IX (Cancelled), of tubular form having at one end a head 34 and a part of smaller diameter 36 which engages in a semi-circular groove 31 in the panel edge.

Abstract: 709,351. Aerials; aerial coupling arrangements. STANDARD TELEPHONES & CABLES, Ltd. July 11, 1952 [July 21, 1951], No. 17562/52. Classes 40 (5) and 40 (7) An antenna system comprises a first conductor spaced a small distance above a second wider conductor, the wider conductor having openings there'n across which the first conductor extends whereby part of the energy propagated along said conductor is radiated by said openings. In one embodiment the first conductor 1 is a continuation of the centre conductor of a feeding co-axial cable 5 and is spaced a small distance above a ground plate 2 connected to the outer conductor which forms the second conductor. Slots 3 are cut in the plate 2 and form a radiating array across each of which the conductor 1 passes to energize it. A termination 4 is provided physically supporting the end of member 1 and electrically comprising either a matching impedance or a short circuit. Fig. 3 (not shown) shows an array in which the conductor 1 is forked each part passing over a series of slots similar to those shown in Fig. 1. The embodiment shown in Fig. 4 is one designed to give circular polarization. In it slots 11 and 12 are formed in the ground plate at right angles to each other and at positions spaced apart an odd multiple of a quarter wavelength along the conductor 1. The conductor and the ground plane containing the openings may comprise layers of conductive material printed, embossed, or photographically applied, to opposite sides of a dielectric supporting member. The termination may be an extended area forming a capacity or an inductive stub, Figs. 5 and 6 (not shown). In a further embodiment, Figs. 7 and 8, the ground plate 18 is between two layers of insulation 21 and 22 the outer sides of which carry respectively conductors 19 and 20 crossing slots 23 and 24 in the plane 18. Conductor 20 extends unbroken as one conductor of the feeder and the other conductor of the feeder 25 is directly connected to the slotted ground plate 18. Conductor 19 is led down over a slot 29 in conductor 25 and is terminated by being shorted to that conductor by a connection 28 quarter of a wavelength beyond the slot. It is energized through the slot by conductor 20 which passes across the slot on the opposite side. The insulating materials 26 and 27 spacing the conductors are selected to have differing constants so that the voltages on lines 19 and 20 are 180 degrees out of phase.

Title: Improvements in centrifugal compressors
Inventor: SCHWAAR PIERRE GEORGES
IPC: F04D21/00
Filed: 1957-06-04
Abstract: 818,655. Centrifugal and axial-flow compressors. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'- AVIATION. June 4, 1957 [June 11, 1956], No. 17760/57. Class 110 (1). An air compressor comprises a radial-flow stage having an axially-directed intake end, and an axial-flow transonic stage upstream of the intake end and having transonic blades of diffrent outlines at the root and tip, the outlines being such that the compression ratio is greater at the tip than at the root. The compressor shown comprises stator blading 1, 6, axial-flow rotor blading 4 and centrifugal blading 7. The flow past the blading 4 is transonic, i.e. both subsonic and supersonic velocities are present in the flow, and the Mach number varies, say, from 0.690 at the blade roots to 1.15 at the tips. The flow passage converges slightly over the extent of the blading 4 and 6. The air leaves the blading 6 in an axial direction at the root but retains a small whirl component of velocity at the tip. The positive pre-whirl thus provided at the outer radius of the inlet eye of the centrifugal impeller ensures that the relative velocity at the inlet to the blading 7 remains subsonic despite an increase of dimensions represented by the shaded area 7a. The dimensional increase allows the mass flow to be increased without increase of the overall diameter of the impeller. The pre-whirl reduces the compression ratio obtainable at the outer radius, but this is compensated by varying the profile of the blading 4 from root to tip to produce a variation of the compression ratio of the axial-flow stage, say, from 1.3 at the root to 1.8 at the tip.
