Patent CA-2210861-A1 (CA)
Title: Multichannel high-speed data transfer
Inventor: JOKINEN HARRI
IPC: H04L25/14
Filed: 1996-12-17
Abstract: A digital mobile communication system has a high-speed non-transparent data connection between a transmitting and a receiving party (MS, TAF). For the data connection, parallel subchannels (chl-chn), corresponding in number to the nominal data transfer rate, have been allocated on the radio interface. A radio link protocol (RLP) is responsible for transmitting data over the radio interface, and for acknowledging correct data frames and for retransmitting defective data frames. A transmission buffer (63) buffers the data frames to be transmitted and stores the data frames transmitted until it receives an acknowledgement of successful reception. In order to reduce interference and power consumption, user data is transmitted by using as many of the allocated subchannels as required by the actual user data rate at any one time. On the other allocated subchannels, transmission is interrupted or discontinuous transmission is activated.

Abstract: A reduced-fat dairy spread which is spreadable at refrigeration temperature, has the appearance, flavour, consistency, rheology, and mouth-feel which is similar to conventional butter. The dairy spread has a formulation which comprises 0% upto 43% by weight of butterfat, 30% up to 75% by weight of water, 10% up to 30% by weight of milk solids, and 0% to trace amounts of each of a butter culture, salt, and annato colours which are compatible with butter. The soft but solid appearance, and refrigeration temperature spreadability, of the dairy spread is achieved as a consequence of protein coagulation at elevated temperatures of a stirred mixture of starting materials. The liquid starting materials, heavy cream or milk, are unhomogenized, homogenization of the mixture does not occur until after protein coagulation at elevated temperatures has taken place.

A further pedal actuator is pivotally secured to the vehicle and operably connected to the slave cylinder, the arrangement being such that upon the actuation of the slave cylinder, the further pedal actuator is pivoted from a released first location to an applied second location thereof. A further master cylinder is hydraulically connected to the reservoir and operably connected to the further pedal actuator. A brake system is hydraulically connected to the further master cylinder such that when the further pedal actuator is pivoted towards the applied second location, the further master cylinder pumps hydraulic fluid from the further master cylinder towards the brake system so that the brake system is applied for braking the vehicle. The arrangement is such that braking of the vehicle is accomplished by movement of at least one of the pedals towards the respective second location.

Patent CA-2222982-A1 (CA)
Title: Mulching mower deck
Inventor: BENTER DEAN WILLIAM
IPC: A01D34/00
Filed: 1997-12-18
Abstract: A mulching mower deck within which first and second mower blades rotate for cutting grass, having first and second blade chambers positioned adjacent each other and within which respective blades rotate during operation. The first and second blade chambers are generally completely enclosed for generally confining grass clippings within the blade chambers for preventing the clippings from exiting through side or top walls of the mower deck. The first and second blades travel in respective paths which overlap. The first blade is positioned to the right of the second blade with respect to forward operation of the mower deck and travels in a clockwise direction, and said second blade is positioned to the left of the first blade and travels in a counterclockwise direction. An opening is formed between the first and second blade chambers at a location where the blade paths overlap. Edges of said opening are positioned relatively close to the first and second blades near where the blade paths overlap. A flow divider defines the opening and is positioned generally above the location where the blade paths overlap, and extends downwardly from the top wall of the mower deck to a position in relatively close vertical proximity to the rotating blades where the blade paths overlap. The flow divider includes a portion directly in front of where the blade paths overlap, which acts to divide and direct air and clippings to respective blade chambers.

Patent CA-2230793-A1 (CA)
Title: Gasoline desulfurization process
Inventor: HICKEY THOMAS P
IPC: C10G45/32
Filed: 1996-07-12
Abstract: A catalytic cracked naphtha is desulfurized with minimum loss of olefins and octane. The naphtha is fed to a first distillation column reactor (10) which acts as a depentanizer or dehexanizer with the lighter material containing most of the olefins and mercaptans being boiled up into a first distillation reaction zone (11) where the mercaptans are reacted with diolefins to form sulfides which are removed in the bottoms along with any higher boiling sulfur compounds. The bottoms are subjected to hydrodesulfurization in a second distillation column reactor (20) where the sulfur compounds are converted to H2S and removed. The lighter fraction containing most of the olefins is thus not subjected to the more harsh hydrogenation conditions of the second reactor (20).

Title: Process for producing signals identifying faulty loops in a polyphase electrical power supply network
Inventor: JURISCH ANDREAS
IPC: G01R31/08
Filed: 1996-11-22
Abstract: The invention relates to a process for producing signals identifying faulty loops in a polyphase electrical power supply network using impedance starting, during which process the signals identifying the faulty loops are formed after checking for earth faults by comparing the amounts of the impedance values produced during impedance starting. To eliminate during said process with great reliability all the loops which are not actually faulty in spite of initial starting the invention proposes that actual faulty loops are determined while determining exclusively earth-faultless loops by comparing calculated virtual impedances (ULx-Ly/ILx; ULxLy/ILy) with impedances (ZLx-Ly) measured during impedance starting; by determining at least one loop with earth fault, faultless phaseto-ground loops are recognised and eliminated by comparing the amounts of the virtual impedance values (ZVLxE) obtained from the impedance values of the phase-to-ground loops, detected as faulty, with the smallest virtual impedance values (ZVLxE). To use the impedance values of the other loops determined as faulty but not eliminated, examination processes (23, 24, 25) designed in various ways according to the number of simultaneously established phase-to-ground loops are used.
