Patent CA-2121535-C (CA)
Title: Infeed means for comminuting machine
Inventor: DOPPSTADT WERNER
IPC: B02C13/30
Filed: 1994-04-18
Granted: 1999-10-26
Abstract: The comminuting machine includes a housing provided with a rotary impact mechanism. Infeed apparatus including a conveyor and a revolving intake roll act upon the infed material for conveying the same to the rotary impact mechanism. An entrance gap is defined between an impact ledge and the rotary impact mechanism and provides initial comminution. The impact ledge is mounted at a carrier which also supports a pressure fluid operated motor for driving the infeed apparatus. The entrance gap is followed by an impact plate which cooperates with the rotary impact mechanism in further disintegrating the infed material.

Title: Method for injection stretch blow molding of polyethylene
Inventor: NAKAJIMA HISASHI
IPC: B29C49/42
Filed: 1994-10-21
Granted: 2000-06-27
Abstract: A novel method enabling stretch blow molding in a temperature range preferable for polyethylene, capable of releasing at a surface temperature suited to both releasing of a preform and subsequent stretch blow molding, by disconnecting the core die and the preform in advance by the use of pressure of gas.     This is for injection molding a predetermined preform by filling an injection mold with molten polyethylene, releasing the preform from the cavity die and core die of the injection mold while a mouth portion of the preform is held by the lip die, and transferring the preform into a blow die to stretch blow mold into a hollow molded product of thin wall. Gas is forcedly entered into the boundary of the core die and the preform, before releasing the preform from the injection mold, to isolate the inside wall of the preform from the core die. Releasing is effected while the inside of the preform is not completely cooled and is still at high temperature, and in a temperature range in which the surface temperature of the preform right after releasing is 80 to 90 deg. C. The step of stretch blow molding is performed within the time interval before the surface temperature of the preform which is elevated by the internal heat of the preform reaches 120 deg. C.

Abstract: A gateway computer is connected to a wireless station switch which receives  and sends  transaction processing  data  between  remote  terminals  and  a transaction processing host.   The gateway interprets an exception code in the data packet received from the terminals to determine whether data is to be forwarded or whether a predetermined circuit management activity is to be carried out by the gateway for the purposes of  call  request,   call  accepting, acknowledging, negative  acknowledging,  call  clear  requesting,  call clear  confirming  or  call  reset  confirming.    The terminals make use of the exception code to make it easier for the gateway to either pass on data or carry out  the  predetermined  circuit  management  activity while reducing both the amount of interpretation and processing required by the gateway and reducing over-the-air traffic between the terminals and the wireless station.

Title: Interactive subscriber telephone terminal with automatic management software download feature
Inventor: GORDON IAN R
IPC: H04M1/2749
Filed: 1997-10-29
Granted: 2003-06-03
Abstract: Interactive subscriber telephone terminals have a display screen and softkeys which are controlled by management software.  The management software may be downloaded from a remote server to control the display and softkeys.  Different techniques for achieving this download are described.  In one case each subscriber terminal has a memory in which can be preloaded a list of one or more Calling Line ID numbers corresponding to the telephone number of a server(s).  If a server dials the subscriber terminal the calling line ID is compared with the list and, if there is a match, the terminal immediately goes off-hook and follows the protocol for a Server Initiated Download.  In an alternative case each subscriber terminal is capable of calling out to predetermined server lines to obtain the ADSI scripts.  This dial out of stored telephone numbers may be done on an automatic timed basis or may be initiated by a server calling a pager embedded in the subscriber terminal.
