Title: Hydraulic brake controller
Inventor: KOSHAK JOHN W
IPC: B66F3/30
Filed: 1998-03-16
Granted: 2007-01-02
Abstract: The invention includes a brake system for a hydraulic ram (3) or another cylinder, that can be employed as an emergency brake for a lifting elevator. When actuated, the brake arms (27) contact the ram circumferentially to slow and stop the falling ram. The brake arms are preferably lined with accretable material that frictionally engages the ram to stop the downward motion of the ram. The brake system may be actuated by the loss of hydraulic pressure, by an electronic signal from a hydraulic pressure detector, by down overspeed sensor (40) or by an uncontrolled down motion detector. According to another aspect of the present invention, a controller, which is preferably a programmed control system, compares the actual motion of the elevator as sensed by a detector to a desired motion. Under certain conditions, if the actual motion differs from the desired motion, the controller actuates the brake.

Abstract: An expandable waterproof covering system used to protect sub surface areas of a building where the sub surface areas meet at an angle. The covering material is a sheet of expandable waterproof material such as a reinforced dual polycrepe material. Approximately in the centre of the covering sheet is a pleated are with a series of folds on each side of the centre. The centre of the sheet is fit over the joining centerline of the two sub surfaces areas to be covered. If desired, a section of the folds may be restricted in their expansion by stitching the adjacent folds together. With this construction the lower folds may fan out to expend to cover more of the surface areas to be protected than the sections that those fold section which are restricted. This find particular applicability to covering the outside corners of building before the final exterior veneer layer, such as brick or stone, is applied over the protective covering.

Granted: 2007-06-19
Abstract: In an induction heating roller apparatus of the present invention, Rolling bearings 10 and a sliding bearings 14 are provided between drive shafts 2 of a roller body 1 and a support rod 9. When a trouble occurs in the rolling bearings 10, a rotational torque is transmitted from the drive shafts 2 through the rolling bearings 10 to the support rod 9. The sliding bearings 14 operate during the transmission of the rotational torque to the support rod 9, and the rolling bearings slips relative to the support rod 9. The slip prevents that the support rod 9 co-rotates with the drive shafts.

Title: Patterned boiled egg and process for producing the same
Inventor: UMEHARA HATSUYO
IPC: A23L15/00
Filed: 1999-12-09
Granted: 2010-07-13
Abstract: The curved surface inside the egg shell of an edible boiled egg is decorated by patterning so as to satisfy consumers' needs for tasteful table setting. The pattern is formed by using exclusively the inherent components of the egg without introducing any foreign matter thereinto, which causes no fear from the viewpoint of food sanitation management. On the albumen layer (9b or 21a), serving as the background, which has been formed by the coagulation of the albumen (3c) on the curved surface of the boiled egg, a pattern layer (19a) is formed by the coagulation of the yolk (3g). On the yolk layer (9a or 3gf), serving as the background, which has been formed by the coagulation of the yolk (3g) on the curved surface of the boiled egg, a pattern layer (3e) is formed by the coagulation of the albumen. These pattern layers (19a and 3e) are formed by site-selectively and intensively heating the outer surface of the egg shell (3d).

Title: Rotary piston engine
Inventor: DI PIETRO ANGELO
IPC: F01C1/46
Filed: 2000-07-14
Granted: 2008-10-28
Abstract: A non-reciprocating engine comprising a hollow cylindrical shaft driver (13) located in a cylindrical stator cavity (14) of a stator. A number of expansion chambers (43) form between the outer wall of the shaft driver, the stator wall and movable dividers (25) which extend from the stator to bear on the shaft driver. The expansion chambers expand and contract during operation of the engine. An output shaft passes centrally through the stator cavity an d shaft driver and has offset bearings (34) which bear on the inside surface of the shaft driver. Inlet ports in a removable inlet end plate of the stator allow pressurised air or air/fuel mixture, for example, to be introduced into the expansion chambers. Sequenti al expansion and contraction of the chambers around the circumference of the shaft driver causes a combination of orbital and rotational movement of the shaft driver and consequential rotation of the output shaft. The shaft driver rotates at only a fraction of the speed of rotation of the output shaft (in the order of 1/10th - 1/20th the speed of rotation of the output shaft). One orbit of the shaft driver is equivalent to one rotation of the output shaft.

Title: Rapid oxygen absorption by using activators
Inventor: EVANS SUSAN P
IPC: B01J20/22
Filed: 2000-09-27
Granted: 2007-12-18
Abstract: Absorbing oxygen from a closed space at a rapid rate, particularly in food packaging, is made possible by introducing an alcohol-water mixture as an activator for iron-based absorber systems, preferably including an acid to control pH. Preferred alcohols are aliphatic alcohols, particularly, monohydric alkanols, such as methanol, ethanol, n-propanol, isopropanol, sec - butanol and t-butanol. Such absorber-activator combinations are capable of rapidly reducing the oxygen in a closed package. A preferred acid is orthophosphoric acid used in an amount sufficient to establish a pH of about 0.6 to 4. A preferred iron-based absorber system employs sponge iron, optionally including a dibasic acid cooperating with the orthophosphoric aci d to control pH in the system. In one preferred embodiment, the iron-based absorber is pre-activated by contacting with the activator in the substantia l absence of oxygen for a predetermined period of time.

Patent CA-2399692-C (CA)

IPC: G01N27/416
Filed: 2001-02-07
Granted: 2009-01-20
Abstract: An electrochemical sensor (A, A') is specific for the detection of peracetic acid in a solution which also contains hydrogen peroxide. A potential is applied between a reference electrode (120, 120') and a working electrode (118, 118'). A read voltage (fig. 7) is selectively pulsed to the working electrode and then through the solution to a counter electrode (122, 122'). The current flowing between the working electrode and the counter electrode is dependent on the peracetic acid concentration in the solution (fig. 6). By careful selection of the read voltage, the contribution of hydrogen peroxide to the current flow is virtually negligible. The sensor effectively measures peracetic acid concentrations in the range generally employed in sterilization and disinfection baths (100-3000 ppm.).
