Title: Keyboard express typing system
Inventor: FREEMAN ALFRED B
IPC: B41J5/10
Filed: 1989-12-20
Abstract: KEYBOARD EXPRESS TYPING SYSTEM  Abstract of the Disclosure A keyboard input system (15) uses key combinations, or chords, in a number of ways to input information faster.  Keyboards (11) range from augmented standards to one with ten keys, and chords range from ones very easy for typists to ones of all row key combinations by each hand.  Chords of one stroke type the most frequent words along with regular typing or other chording of less frequent words.  Other chording handles words as stems, or roots, and inflections which change words to different grammatical forms.  Stem coding minimizes inputs for stems and data accompanying stems reduces inputs for inflections.  A software program (17) to "Terminate but Stay Resident" with MS DOS on IBM Personal Computers and compatibles implements the preferred embodiment of the system for English.

Title: Low temperature air fractionation accommodating variable oxygen demand
Inventor: ROHDE WILHELM
IPC: F25J3/04
Filed: 1990-04-26
Abstract: A process and apparatus for the low-temperature separation of air with variable oxygen production are described. Compressed, pre-purified and cool air (line 5) is pre-separated in the pressure stage 10 of a two-stage rectification 9. The bottom liquid thus formed is further separated in the low-pressure stage 11. Liquid nitrogen 14 from the pressure stage 10 and liquid oxygen from the low-pressure stage 11 can be temporarily stored in tanks 35, 32. In addition, a liquid-air tank 14 is provided for storing bottom liquid 12 from the pressure stage 10. If the production of oxygen is increased, the throughput in the pressure stage 10 can be increased and at the same time the throughput in the low-pressure stage 11 and the reflux ratios in the two rectification stages 10, 11 can be kept constant.

Patent CA-2019582-A1 (CA)
Title: Nestable and stackable tray for cans or the like
Inventor: APPS WILLIAM P
IPC: B65D1/36
Filed: 1990-06-21
Abstract: Reusable plastic trays for storing and transporting beverage containers, such as twelve-ounce metal cans and two-liter PET bottles. The tray floor has thereon an array of support areas for the containers. The tray rail band thereof is spaced high enough above the floor to prevent container tipping and in a "low-depth" configuration. The outside rail band faces are vertical on both sides and are against the containers, and thereby add little to the outside tray dimensions. The inside face contacts and supports the peripheral containers. Columns between adjacent support areas interconnect the rail and the floor, angle downwardly and inwardly therebetween, open outwardly and form vertical nesting slots. The trays when empty can thereby be stacked in a deeply nesting position whereby each additional tray adds only the height of its narrow rail to the nested tray stack height. When the tray is a can tray, the bottom surface of the floor has a pattern of protuberances and recessed areas therebetween. When a loaded can tray is supported and located on a similar tray therebeneath, the lower can rims fit into the recessed areas and the protuberances are positioned both inside of and outside of the rims thereby locating and locking the upper tray in place. To unlock the upper tray it is simply twisted so that the protuberances ride up their bevelled edges onto the rims and into a sliding position.

Title: Method of, and apparatus for, detecting the position of a marking or separating element in a stack of substantially flat products
Inventor: BLUMER HANS
IPC: B65H7/14
Filed: 1991-10-24
Abstract: METHOD OF, AND APPARATUS FOR, DETECTING THE POSITION OF A MARKING OR SEPARATING ELEMENT   IN A STACK OF SUBSTANTIALLY FLAT PRODUCTS     ABSTRACT OF THE DISCLOSURE         For detecting and pushing up marking or separating elements in a stack of labels, there are provided a detector arrangement and an ejector element, both of which are mounted at a  support  or  carriage  connected to  a  revolvingly drivable traction element.  By setting a driving motor in operation, the support or carriage is moved along the underside of the stack. As soon as the detector arrangement reaches a position in which it is aligned with a marking element, the presence of the marking element is detected by means of the thereby resulting brightness difference.  The ejector element is then brought into alignment with the respective marking element and the latter is pushed up by means of the ejector element, so that the marking element protrudes somewhat from the top of the stack.  Subsequently, the label package located directly in front or downstream of this marking element is separated from the remaining part of the stack by means of a part-off blade which is driven into the stack, directly behind or upstream of the pushed-up marking or separat-ing element.
