Abstract: ENERGY SAVING PROTOCOL FOR A TDM RADIO     ABSTRACT of the DISCLOSURE      A battery powered TDM (or combined TDM/FDM) communication device (104,105) operates within a TDM communication system (100) having a communication channel arranged into repetitive time frames (401) each having a plurality of slots. At least two of these slots (404) are allocated for communicating signalling and control information. To conserve energy, the battery powered communication device operates in a first mode (i.e., the energy saving mode) to shut down non-essential circuits for a predetermined time interval, awaking to monitor one of the two control slots. In this way signalling and control information may be received. When not operating in the energy saving mode, the battery powered communication device operates in a second mode (i.e., a fast access mode) to monitor at least two of the control slots (404).

Abstract: ABSTRACT Large sheets of float  glass or other large sheets of material are transferred from a vertical storage position to a horizontal surface automatically.  A carriage is mounted on a support frame near the stack of sheets of material, which rest against an inclined surface such that the bottom of each sheet is located forward of the top thereof to cause the plane of the stack of sheets to tilt a few degrees past vertical.  A sheet engaging member is located on the carriage for pulling the top sheet of the stack forward, pivoting the sheet on its bottom, to a point where the top of the sheet is moved past vertical on the opposite side from the stack of sheets to an unstable position. In this position,  the sheet is released to free fall to a horizontal position on a support surface located in a horizontal plane adjacent the bottom of the sheets in the storage position.

Title: Anti-disaster monitoring system and anti-disaster monitoring method
Inventor: KIKUCHI MASAMICHI
IPC: G08B26/00
Filed: 1991-08-21
Granted: 2001-10-16
Abstract: Disclosed is an anti-disaster system for receiving terminal data in response to the sequential calling of the terminals which is achieved by designating addresses from a receiver and for performing alarming or the like. Each of the terminals has an interrupt transmission section for transmitting a break signal which invalidates a terminal response signal on a timing when the terminal response signal to the receiver is transmitted when an abnormality is detected to notify generation of an interrupt. The receiver includes an interrupt detection section for detecting an interrupt of a terminal when it receives the break signal at a timing when the terminal response signal is received, and a calling control section for specifying the terminal in which abnormality data is detected, the specification being achieved by transmitting the calling signals for interrupt confirmation to the terminals when an interrupt detection output is obtained from said interrupt signal detection section to allow the terminal to transmit the terminal response signal containing an interrupt level signal which indicates the cause of generation of the interrupt and by performing sequential group calling of the terminals on the basis of the order of priority of the interrupt level signal.      Consequently, when urgent data is detected at the terminal end, terminal data can be received quickly independently of the sequential calling and generation of an abnormality can be determined. Furthermore, since an interrupt confirmation request is made from the receiver to the terminal in response to the interrupt based on a break signal so as to allow the terminal to notify the cause of generation of the interrupt, an adequate processing, corresponding to the cause of generation of the interrupt, can be executed on the receiver end.

Title: Apparatus for the preparation of hot drinks
Inventor: WEBER RENE
IPC: A47J31/30
Filed: 1991-10-28
Granted: 2002-07-16
Abstract: Apparatuses for the preparation of different hot drinks, such as in particular espresso machines, conventionally have a multiway valve (2), which is used for supplying hot water or superheated steam produced in a water heater to different means, such as coffee filters, frothing nozzle and/or collecting vessels. As a result of high temperatures and pressures the multiway valve is exposed to considerable stresses, which in the long term cannot be withstood by known valves or only when a complicated and costly construction is adopted. In the novel apparatus the multiway valve is provided with a perforated disk (8) and a rotary control dial (9). Rods (14) for closing the distributing passages (5) are passed through the holes in the perforated disk. The distributing passages are provided in a distributing block (1) to which the multiway valve is flanged. The posi-tion of the rods is determined by the rotary position of the control dial provided with a guide link for the rods.
