Abstract: The present invention is directed to aqueous cleaning compositions such as for household use or for cleaning electronic circuit assemblies comprising alkaline salt, an alkali metal silicate to boost detersive action or to provide corrosion protection to the substrates which are cleaned and an anionic polymer which stabilizes the alkali metal silicate to prevent precipitation of the silicate from solution.
Patent CA-2131784-A1 (CA)
Title: Particle analysis and sorting
Inventor: TAPPER ULF A S
IPC: B07B/
Filed: 1994-09-09
Abstract: ABSTRACT          The invention relates to a method and apparatus for analysing samples for the presence of a particular element or isotope. In the method a pulsed neutron beam is directed at the sample. The beam is at an energy level chosen for the neutrons to interact with the element or isotope and produce a detectable gamma spectrum. A gamma detector detects the neutron-induced gamma spectrum. The detector is time-gated in such a manner that neutron-induced gamma radiation is detected while neutrons scattered by the sample are at least substantially excluded. Analysis of the spectrum enables a determination to be made as to whether a spectral peak characteristic of the particular    element or isotope is present. The invention  also provides apparatus  for carrying out the method.

Title: Beverage dispenser
Inventor: MILLS JEFFREY P
IPC: B67D1/06
Filed: 1995-01-31
Abstract: A dispenser combines the efficiency of a post-mix dispenser, while providing the visual appeal of a visual spraying dispenser. A bowl holds a liquid that is circulated through a cooling system to provide a cool spray, and thus to create condensation on the outside of the bowl. The beverage that is dispensed is from remote supplies of concentrated syrup and water. The bowl has a single body that defines a number of compartments. The body is covered with a lid, and rests on a concentrate tray that drains away condensate that build up on the body. The body is easily removably and replaceably coupled to the tray. The valves for dispensing are on a movable support so that the height of the dispenser can be made smaller while still providing manual access to the valves.

Title: Apparatus for measuring the speed of hockey shots having a retractable slap shot obstruction lever
Inventor: TISON MARC
IPC: A63B71/06
Filed: 1995-04-06
Abstract: An apparatus for measuring the speed of hockey shots comprises (a) a simulative puck to be propelled by a person by means of a hockey stick, this puck being propelled from an initial position toward a given direction, (b) a carriage/track assembly for guiding the propelled puck along a predetermined trajectory, and (c) a computer system for measuring the speed of the propelled puck moving in the given direction along the predetermined trajectory. The computer system comprises a keyboard for selecting a wrist shot or a slap shot. This computer system further controls rotation of a pivotal lever from a first angular position in which the lever is retracted from the shooting surface to enable propelling of the puck from its initial position by means of a slap shot, to a second angular position in which the lever protrudes over the shooting surface. In the second angular position, the lever forms a mechanical obstacle situated in the proximity of the initial position on the side of the puck opposite to the given direction in order to prevent a person having selected a wrist shot to use a slap shot to propel the puck and increase the speed of his shot.

Title: Group call in a cellular radio system
Inventor: YARWOOD ANTHONY CHARLES
IPC: H04W4/90
Filed: 1994-05-23
Abstract: In a cellular radio system the facility is provided for a call to be broadca st from a control centre (Mx), (for example an emergency service controller), or from any of the mobile units (Ma), (Mb), (Mc) etc., to all of the others. Each cell allocates a single channel to the broadcast service, irrespective of the number of mobile units in the cell. This allows more efficient use of the available channels than the use of a separate channel for each mobile unit. In one embodiment no channel  is allocated to a cell unless at least one mobile unit responds to a paging signal in that cell. Paging may continue throughout a broadcast call to allow a channel to be allocated when a mobile unit enters a previously unoccupied cell or to allow please of a channel should all mobiles leave a previously occupied cell. The broadcast facility can be provided on a cellular network which also supports other mobile units whi ch do not receive the broadcast service, and whose operation is not affected by it.
