Abstract: A heat pump system has a refrigerant circulation system that is cooled by passing through a thermal storage heat exchanger. The heat exchanger is supplied by ice from an ice maker and can store heat energy by accumulation of ice in the heat exchanger. The ice is generated by cooling a secondary refrigerant, typically brine, at the wall of a ice making machine and scouring the wall prior to crystallisation of the brine mixture to disperse the super cooled liquid adjacent the wall into the body of the secondary refrigerant. Crystallisation is then promoted in the body of the liquid. The ice generator in a preferred form comprises a series of flat plates having primary refrigerant passing between the flat plates and secondary refrigerant passing over the surface of the flat plates. A series of scrapers rotate about an axis normal to the plane of the plates to disperse super colled secondary refrigerants throughout the body of the secondary refrigerant in the ice generator.

Abstract: A machine for conditioning a stack of pads, such as sanitary pads, for packaging, includes a rotor. Radially extending chambers (9-16) having closed sides (17, 18) and open front and rear ends are fastened to the rotor. There is a compressor plunger (70) in each chamber. The plungers are carried on guide rods (72) extending from cam follower brackets (74). A stationary cam plate (65) is mounted perpendicular to the rotational axis of the rotor. The follower rollers (67) are spring biassed into contact with the periphery of the cam plate (65). The chambers (9-16) are incremented in angular steps starting with a position in which the chamber is stopped momentarily for being loaded with a stack of pads at which time its plunger is retracted. As the loaded chamber increments in two angular steps to an unloading position, the plunger is driven out by the cam to compress the stack. When the chamber rotates from the loading position to the unloading position, the pads are effectively turned so they are standing on their edges in the unloading position.

Abstract: The invention relates to a method for controlling a digital communication system having a central data processor and several decentralised input/output processors controlling peripheral devices, the decentralised input/output processors in each case exhibiting multiple-access memories and their own interface device for internal information transmission with the central data processor and the central data processor accessing the peripheral devices in interleaved manner during faultless operation and with the access of the central data processor to the multiple-access memory of in each case a particular input/output processor, the latter being switched into the hold state for a time corresponding to the maximum occupation time of the central data processor. The central data processor (DP) places the decentralised input/output processor (IOP) into the hold state. The peripheral program requests occurring during this process are stored in the multiple-access memory (DPR) and are subsequently sequentially processed by the timing device (ZE) of the input/output processor (IOP) after the central data processor (DP) has been blocked. Such a method is used for controlling digital communication systems in which a central data processor and decentralised input/output processors have shared access to one memory. <IMAGE>

Abstract: The output signal of an analog value memory which, for example, provides the ideal positional value for an analog positioner, on the one hand is intended to be accurately adjustable and on the other hand the time required to adjust the output signal over a wide range is intended to be as short as possible. However, if the adjustment speed for the output signal is high, accurate adjustment of this signal is impossible. The counting frequency (f1) supplied to the clock input (15t) of an up-down counter (15) increases each time the manual control keys (12, 13) are pressed to adjust the output signal (ysoll) of the analog value memory (1), starting from an initial value (f1min), depending in temporally linear fashion on the length of time that the manual control keys (12, 13) are pressed up to a maximum value (f1max). The change in the counting frequency (f1) supplied to the up-down counter (15) is achieved via a second counter (19) supplied with a fixed counting frequency (f0), behind which a further digital/analog converter (20) and a voltage-to-frequency converter (18) are connected. The analog value memory is suitable in particular for the incremental adjustment of the ideal analog positional value of an analog positioner with queued acknowledgement of the actual positional value. <IMAGE>

Abstract: In an optical packet switching system, a plurality of first wavelength tunable devices (13) are connected respectively to incoming line terminals. In response to an incoming signal at the associated incoming line terminal, each of the first wavelength tunable devices generate an optical packet of a particular wavelength determined by a first wavelength selection signal supplied from a controller (14). In one embodiment, packets from the first wavelength tunable devices are switched through one or more paths set up by an optical space division switch (15) to one of a plurality of optical buffers (16). Second wavelength tunable devices (17) are respectively coupled to the outputs of the optical buffers for detecting a packet of a desired wavelength in response to a second wavelength selection signal from the controller (14) and applying the detected packet to one of outgoing line terminals. Each of the optical buffers is made up of an optical coupler having parallel waveguides one of which is disposed in the signal transmission path, the other being disposed in an optical loop for recirculating a packet.

Abstract: The present invention is directed to a method for the formation and dry development of photoresists treated only in a thin layer ( i.e. , approx. 2000 Angstroms thick) so as to be treated with an organometallic material. Treatment of this thin layer of the resist formulation in the process of the present invention is preferably accomplished by the vapor phase exposure of the resist formulation to an organometallic material such as a silylating compound capable of reacting with the resist formulation. The resist formulation also contains a photoacid generator, capable of releasing an acid which either causes the hydrolysis of the exposed portions of the resist that were created with organometallic vapor, or prevents the reaction of the organometallic vapor with the exposed portion of the resist.
