Title: Ice making machine - having high efficiency under a wide range of ambient conditions
Inventor: ALEXANDER ROBERT WILLIAM
IPC: F25C1/04
Filed: 1975-04-23
Abstract: In a process for making ice by absorption of heat from a container filled with water, heat is applied to the container after ice has formed until the interfaces between the ice and the container have thawed and the container is filled with water to expel the ice (which floats on the water). The vessel, now refilled with water, is again subjected to heat absorption to form further ice. The machine has a comparatively simple control system; can produce 200 lbs of ice per 24 hrs. using a 1/4 H.P. power source, compared with a capacity of 50-60 lbs for a previous machine operating under the same ambient conditions of 80 degrees F. This achieved by employing a system in which the thermal capacity of the refrigeration circuit is high compared with that of the vessels contg. the water to be frozen.

Title: Thickness measuring instrument - measures thickness of thin sheets and other geometrical dimensions of a product using electro-optic method
Inventor: PIRLET ROBER
IPC: G01B11/00
Filed: 1975-10-21
Abstract: A thickness measuring instrument to determine the dimensions of a product, particularly metal beams, is based on the production of optical images on a set of photodiodes, and in measuring the sweep time of these diodes. A time counter is used and started when the diode situated at the illumination centre of an image is detected and stopped when the diode of another set of photodiodes also detects the illumination centre of another image. The time interval is a measure of the dimension to be determined. The diode situated at the illumination centre of an image is determined by measuring the illumination measured by each diode of a set and by determining the differences between the light intensity of diodes in a pair.

Title: Fusible conductor for inertial fuses - uses specified layer for separating conductor from alloying metal components
Inventor: BORCHART HANS-F DIPL ING
IPC: H01H85/055
Filed: 1975-11-18
Abstract: The serially produced fuse uses a fusible conductor provided with a separating layer which does not form an alloy with the conductor material. The coating leaves free a section reserved for alloying. The separating layer may be of electrically conductive, or non-conductive material. Its thickness is variable in order to provide variable inertia of the conductor. Preferably the separating layer is distributed over the entire length of the conductor. In such instance the thickness of the layer is so rated that the applied alloying material can diffuse through the layer into the conductor with a rated delay.

Title: Hot blast stove appts - includes temp equaliser to enable continuous supply of hot gases to blast furnace
Inventor: TAKEUCHI KIKUO
IPC: C21B9/10
Filed: 1976-05-18
Abstract: Hot blast stove appts. comprises a regenerative hot blast stove containing combustion heating means and heat regenerative material heated by the heating means. An outlet for the discharge of hot blast gases from the stove is connected to a main hot blast gas duct. Valves control the cyclical discharge of hot blast gases from the stove to the duct. A temp. equaliser absorbes heat from the hot blast gases at the beginning of a discharge cycle of hot blast gases from the stove to store the heat and release the stored heat to the hot blast gases at the end of the discharge cycle. Thus the hot blast gases are delivered from the duct at an equalised temp. during the cycle. The regenerative layer can be decreased to about one half of that in a conventional stove. Cooling air is not required to equalise the temp. so the control systems can be simplified.
