Patent CA-2158786-A1 (CA)
Title: Window jamb liner and tilt lock
Inventor: STARK IVAN L
IPC: E06B1/00
Filed: 1995-09-21
Abstract: A tilt lock arrangement is provided for a sash slideably/pivotally positioned in a window frame. The tilt lock arrangement includes a window jamb liner made of extruded structural material defining an elongated channel with strips of resilient material adhered to the structural material inside the channel. A sash support is configured to operably slide within the channel proximate the resilient material. A tilt lock member is fixedly secured to the sash and includes a shaft rotatably engaging the sash support, together with a disk-shaped end having flattened sides. The flattened sides define a dimension small enough to allow the tilt lock member and sash support to slide along the channel. However, the disk-shaped end has a diameter large enough to bindingly engage theresilient material on the opposing sides of the channel when the tilt lock member is rotated. Thus, when the sash is tilted, i.e. pivoted away from the window frame such as for cleaning, the tilt lock member is also forcibly rotated and bindingly engages the resilient material in the window jamb liner channel to prevent translational movement of the sash. However, the resilient material has a memory such that when the sash is pivoted back to the unlocked slideable position, the resilient material substantially returns to its original shape and is not permanently deformed.

Title: Cryptographic authentication of transmitted messages using pseudo random numbers
Inventor: KOOPMAN PHILIP J JR
IPC: H04L9/12
Filed: 1994-06-30
Abstract: An automobile door lock receiver module (30) and a plurality of keychain fob transmitter units (16) contain identification numbers, secret initial values, and secret feedback masks so as to authenticate encrypted messages from any of the assigned fobs, indicative of commands registered by closing switches on the fob. Each fob is synchronized with the receiving module by means of a truly random number concatenated with a secret initial value and encrypted, through a linear feedback shift register or other operations. A second secret initial value is encrypted and command bits are exclusive ORed into the low order bit positions; the two encrypted numbers are concatenated and encrypted to form a key word which is transmitted with the fob ID. Sychronization includes decrypting to recover the truly random number and the secret initial value concatenated therewith the truly random number is compared with previously received raodom numbers in order to avoid copying of recently transmitted synchronization commands. Successive lock-related commands utilize the number encrypted from the truly random number and the second secret initial value as starting values, employing a pseudo random number of encrytion iterations. A half-second delay between responses mitigates gaining access through numerical trials. An authenticated panic alarm command operates the headlights and horn of the vehicle but does not alter the synchronization.

Abstract: A sampling cylinder 3 is attached to a process piping 2 through which a slurry flows. A front piston 9 and a rear piston 10 which slide within the sampling cylinder 3 are driven via a driving rod 12 by a fluid pressure cylinder 11. These two pistons 9,10 are allowed to slide to collect the slurry into a sampling space 30 defined between the pistons 9,10. The front piston 9 is brought closer to the rear piston 10 to reduce the volume of the sampling space 30. Thus, only the filtrate in the slurry is fed through a filter 5 into a filtrate collecting tank 6, where pH etc. of the filtrate is measured by a sensor 8. Subsequently, the front piston 9 is brought apart from the rear piston 10 to increase the volume of the sampling space 30. Thus, the filtrate is returned into the sampling space 30 back-washing the filter 5. Then, the slurry in the sampling space 30 is returned to the process piping 2.

Title: Chemical waste treatment
Inventor: RUSSO GAETANO
IPC: A62D3/00
Filed: 1994-11-25
Abstract: A method for the treatment of chemical wastes, particularly recalcitrant wastes such as spent caustic from the oil, gas chemical and petrochemical industries, in which normally slow physical mass transfer of gases between phases, and other chemical reactions, such as carbonation, stripping and oxidation, are facilitated and speeded up.  The result is more environmentally acceptable waste for disposal. It involves the mixing together in a reaction vessel (8) of the first waste fluid with a second fluid by using a mixing device, such as a jet compressor (5), designed to intimely mix the fluids together so as to provide a large surface area of the second fluid relative to the first. The process is applicable to the treatment of chemicals other than waste chemicals.

Inventor: CHOU WU
IPC: G10L15/06
Filed: 1996-07-15
Abstract: In a speech recognition system, a recognition processor receives an unknown utterance signal as input.          The recognition processor in response to the unknown utterance signal input accesses a recognition database and scores the utterance signal against recognition models in the recognition database to classify the unknown utterance and to generate a hypothesis speech signal. A verification processor receives the hypothesis speech signal as input to be verified. The verification processor accesses a verification database to test the hypothesis speech signal against verification models reflecting a preselected type of training stored in the verification database. Based on the verification test, the verification processor generates a confidence measure signal. The confidence measure signal can be compared against a verification threshold to determine the accuracy of the recognition decision made by the recognition processor.

Title: Pneumatic bulk material slug transport process and device with attenuated shocks
Inventor: ILTZSCHE MANFRED
IPC: B65G53/52
Filed: 1996-02-01
Abstract: Methods and devices for the conveyance of bulk materials by a compressible conveying medium and in the form of discrete plugs from bulk materials in pipes are known. A disadvantage is the high-energy and abrupt expansion of the volume of the conveying medium between the plug being discharged and the one following it at the end of the pipe. This disadvantage may  be  avoided  in that  the  amount  (2')  of  compressed conveying medium existing in each case between plugs (1') in sequence in the downstream end portion (12b) of the pipe as compared to the amount (2) of compressed conveying medium (2) existing between plugs (1) upstream (at 12a) of the end portion (12b) of the pipe is reduced. This is particularly achieved by converting the long plugs  (1)  into plugs of reduced  length  (1'),  following  each  other  in  reduced spacing.

Abstract: A system and method of printing value such as postage using a value meter connectable to communicate with a host terminal which includes a printer. The postage meter, sometimes referred to as a vault, includes a processor and storage and the host terminal includes a processor and storage. The printer is provided with a secure non-volatile random access storage and a processor and a key is stored in the non-volatile random Access storage. The key is changed for every print cycle so that it is impossible to print unauthorized postage on the basis of possession of the key used to print the last postage. A change of key is effected by reading the key from the non-volatile random access storage in the printer and changing the key, such as by a pseudo-random number generator, to provide a second key. The second key is stored in the non-volatile random access storage and then encrypted by an encryption scheme known to an authorized postage meter. The encrypted second key is transmitted to an authorized postage meter wherein it is decrypted pursuant to the decryption scheme known to the authorized postage meter. Print data may be securely transmitted to the host and printer by using the decrypted second key to convert the data to be printed. This is then sent to the printer where it is deconverted using the second key to recover the data to be printed.
