Title: Parking buildings having parking lots arranged for endless circulation
IPC: E04H6/42
Filed: 1964-03-25
Abstract: 1,010,683. Mechanical garages. HITACHI Ltd. March 25, 1964 [April 2, 1963], No. 12728/64. Heading B8E. Parking cages C 1 -C 16  are connected to an endless chain 3 which may be driven in either direction so as to bring a specific parking cage to a desired position in the shortest possible path. Fig. 3 shows a direction selection device comprising switches S 1 -S 16  of which eight are operable when a cam K engages rollers provided on the switch-actuating levers L 1 -L 16 . The cam rotates at a reduced rate proportional to the rotation of the chain 3, thus making one complete turn while the train of cages makes one circulation. In the present embodiment, the cam K rotates in a direction opposite to that of the endless chain 3. Switches S 9  -S 16  are shown actuated. Calling relays A 1 -A 16  are associated with push-button switches B r -B 16  (Fig. 5), and with the respective parking cages C 1 -C 16 , the relays being used to set a stopping position in response to a call. In Fig. 6, contactors 11, 12 for effecting normal and reverse rotation respectively of a three-phase driving motor M are energized via a contact of a leftward direction selecting relay L and via a contact Ra of a rightward direction selecting relay R. Fig. 7 shows contacts 11a, 12a of the contactors 11, 12 for controlling the direction of rotation of the motor M. Assuming it is desired to bring an empty cage C 2  down to the vehicle entrance and exit, the push-button B 2  is operated. The calling relay A 2  and the leftward direction selecting relay L are thus energized and contact La is closed. Contactor 11 becomes energized and contacts 11a 2 , 11a 3  (Fig. 7) are closed to cause the motor M to rotate in the normal direction. The cages then move counter-clockwise and a stoppage ordering contact SD is opened as the cage C 2  arrives at the vehicle exit. In the case when it is desired to bring the cage C 15  (not shown) to the exit, and the direction selection device is in the state as shown in Fig. 5, the switch S 15  is in its operative position due to the cam K. Thus the a contact of S 15  is closed and the rightward direction selecting relay R is energized when the pushbutton B 15  is operated. The cages move clockwise and the cage C 15  travels by the shortest path to the vehicle entrance/exit. At this stage the cam K will be positioned such that switches S 7 -S 14  are actuated and, upon operation of any one of push-buttons B 7 -B 14 , the shortest path rightward for the cages C 7 -C 14  is selected. For cages C 15 , C 16  and C 1 -C 6  the leftward path is selected. A modified direction selection device, Fig. 4 (not shown), comprises sixteen coaxially mounted cams corresponding to the cages C 1 -C 16 . The cams control switches S 1 -S 16 .

Abstract: 377,320. Electric brakes. BARKER, G. G., 59, Chancery Lane, London. -(Bendix Brake Co.; 401, North Bendix Drive, South Bend, Indiana, U.S.A.) April 30, 1931, No. 12754. [Class 103 (i).] Brake mechanism under the control of a single pedal wherein the power is taken from an electric power device comprises a friction clutch which in part co-operates with the powerdevice to couple this device to the brakes and in part transmits pressure directly from the pedal to the brakes. The degree of functional coupling of the power device to the brakes is proportional to the excess of displacement of a pedal lever over the displacement of a brake. applying lever. The brake pedal is connected to a lever 82 and the brakes to a lever 78, these levers being respectively mounted on concentric sleeves 26, 24 carrying flanges 76, 74. The ends of a spring 64 of rectangular wire rest against lugs on the flanges 76, 74 so that when the flanges are moved relatively by operation of the brake pedal the spring is expanded against a cylinder 62 integral with a ring gear 42 driven by the electric motor through reduction gearing and the levers are rotated to apply the brakes. The reduction gearing comprises a driving pinion 32 keyed to the shaft 12 of the motor, planet pinions 36 mounted in a-freely revolving carrier 44, 48 and two internal ring gears 40, 42 having their rotative bearing in the housing 22. Ring gear 40 is held against rotation by a spring ratchet 116. Ring gear 42 has two more teeth than ring gear 40 and the gearing is proportioned so that seventyfour turns of the motor turn the ring gear 42 once. The motor 10 is of the low voltage bar wound type receiving current from a storage battery. The armature is supported in overhung fashion on the shaft 12 which is mounted in bearings 14, 16. The endplate 44 of the carrier revolves on an extension of the bearing 14 and is tied by integral arms to the endplate 48 which has a hub revolving in the sleeve 24. The spring ratchet 116 comprises a spring of rectangular wire wound in the opposite direction to the spring 64 and fitting more snugly into its cylinders 112, 114. The cylinder 112 is fixed to the housing 22 and the cylinder 114 is an extension of the ring gear 40. This spring ratchet allows the ring gear 40 to rotate in the opposite direction and permits the brakes to be applied by manual means alone. A switch on the pedal is operated by pressure on the pedal tread to supply current to the motor.

Title: Improvements in or relating to radio signalling systems
IPC: H04B7/005
Filed: 1930-04-25
Abstract: 352,590. Wireless signalling. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. April 25, 1930, No. 12846. Convention date, April 25, 1929. [Class 40 (v).] Telegraph signals are transmitted on a single wave with two modulation frequencies, one for marking and the other for spacing. At the receiving station, marking and spacing signals are separated and applied differentially to a relay. Disturbing signals which affect both signal channels simultaneously and equally are thus balanced out in the relay. As one or other telegraph frequency is always operative, they jointly provide a continuous signal the reception strength of which may be used for effecting anti-fading regulation. By keeping the telegraph frequencies outside the speech-frequency range, the same carrier may be simultaneously used for telephony. Fig. 1 shows a transmitting, and Fig. 2 a receiving diagram. The keying-relay RT closes switches A1, A2 to connect the marking source GI and the spacing source G2 alternately through filters K1, K2 to the radio transmitter S, which is also modulated by a microphone M through amplifiers VV. The mixed output from the receiver E, Fig. 2, is amplified at RV, and the speech frequencies are passed by a filter K6 to a telephone H. The telegraph frequencies pass jointly through a filter K3, are separated by filters K4, K5 rectified at GL2, GL3 and applied differentially to a relay B. The joint telegraph frequencies are also rectified at GL1 and the output from this (proportional to the received signal amplitudes) is utilized to modify the gain of the amplifier RV.

Abstract: 815,725. Combustion apparatus ; recirculating combustion gases. COMBUSTION ENGINEERING Inc. April 30, 1956 [June 21, 1955], No. 13160/56. Class 51 (1). [Also in Group XIII] Fuel is burnt in a boiler furnace in the presence of oxygen and recirculated combustion gases. As shown, pulverized coal is blown into a combustion chamber 4A, Fig. 1, through nozzles 42, Fig. 2, in a recirculated gas stream taken from the boiler gas-flow path by a fan 52 and blown through pipes 60, 56, entraining the coal in the latter pipe as it drops from a hopper 54. Oxygen from a vessel 66 is mixed with the coal and gas before its discharge through the nozzles 42 in such proportions that incomplete combustion ensures and the products, passing through a throat 46 into a combustion chamber 4B, contain a large amount of combustibles. Before its passage through the throat 46 additional gas-borne pulverised coal is added to the combustible mixture through tangentiallydirected nozzles 44. Preferably the nozzle sets 42, 44 are disposed to fire in opposite directions. The gases passing through the chamber 4B are cooled by a high-temperature reheater 30 before admixture with tangentially introduced streams of mixed recirculated gas and oxygen issuing through nozzles 45. The resulting products of complete combustion then pass to a chimney via a high-temperature superheater 20, a low-temperature superheater 16, a low-temperature reheater 26 and an economizer 48. Individual control of superheat and reheat steam temperatures may be effected by controlling the proportions of recirculated gas and oxygen passed into the chambers 4A, 4B. Reheat and superheat temperature variations are recorded by respective devices 80, 84, the temperature impulses received by them being translated into mechanical motion operative in oxygen adjusting valves 82, 78, and recirculated gas dampers 74, 72, by known electric, pneumatic or hydraulic devices 92, 90, 86, 88.
