Title: Coated sodium percarbonate particles, method of producing them and their use
Inventor: BERTSCH-FRANK BIRGIT
IPC: C11D3/39
Filed: 1994-04-23
Abstract: In the prior art, sodium percarbonate is coated with compounds which produce a stabilizing action in order to increase the shelf life. There is a need for an improved, boron-free, coating for sodium percarbonate. Proposed by the invention is a particle coating containing sodium carbonate plus one or more optionally partly hydrated magnesium compounds, preferably magnesium sulphate, in a single coat or in separate coats. The coating preferably contains two coats. The particles are produced by spraying aqueous solutions containing the coating compounds on to sodium percarbonate in a fluidized bed and at the same time evaporating off the water. Their long shelf life makes particles coated in this way suitable for use in washing, bleaching and cleaning agents.

Title: Firearms with rotary magazines
IPC: F41A9/02
Filed: 1981-07-09
Abstract: A firearm especially for firing large calibre rounds such as rubber bullets and having a rotary magazine (2) which is rechargeable at any stage of depletion. A loading (63) arm serves to guide rounds through an inlet opening in the magazine (2), in such a way that they are received into corresponding locations in a rotating carrier (46, 47), and the carrier rotates forward one position with each additional round. Until the penultimate round, the guide means (63, 64, 65) is locked to the magazine body (40). In this position, it obstructs further movement of the first-inserted round and thus prevents insertion of the final round. Mechanism is described by which, on insertion of the final round the guide means automatically unlocks from the magazine body and locks to the rotating carrier. In this condition it serves to keep the first inserted round locked in the magazine as it completes a full rotation to come opposite the inlet opening once more. Mechanism for firing automatic indexing the carrier, and automatic extraction and election of spent cartridges is described.

Title: Measuring device of ac current and method therefor
Inventor: JOHN HELLMAN BLAKELEY
IPC: H01F38/28
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To enable the measurement of a.c. currents with current transformers which saturates at the upper limit of the dynamic range of a current to be measured by generating output signals indicating the selected measurement values of a.c. currents from a secondary current which detects up to the saturation of cores in response to a detection sensor of the secondary current. SOLUTION: Current transformers 17A to 17C are provided with toroidal cores 19A to 19C respectively, and each-phase electric lines 7A to 7C pass through the toroidal cores 19A to 19C respectively to be a primary winding. Secondary windings 21A to 21C generate signals indicating each-phase current. These signals are brought into an A/D converter 23 and digitized at intervals controlled by a microcomputer (μp) 25, and the μp 25 protects a motor 3 from overloads through the use of these digitized signals. In this case, the μp 25 multiplies a coefficient which predicts a current value which does not cause saturation in the rest interval of a sampling period by currents which bring the toroidal cores 19A to 19C into saturation points.  By measuring the secondary current up to the saturation points through this method, it is possible to measure the ac currents of the current transformers 17A to 17C.

Abstract: PURPOSE:To release a partial abrasion and to prevent the generation of a spacing loss by successively changing the hardness of a protecting layer provided on an upper magnetic layer so as to be equal to or below that of a magnetic layer at the upper magnetic layer side and to be gradually increased as it is separated from the upper magnetic layer. CONSTITUTION:On a substrate 10, a lower magnetic layer 11, a non-magnetic insulating layer 12, a coil conductor layer 13, an upper magnetic layer 16, etc., are formed, and thereafter, a protecting layer 17 is formed on them. Here, since the hardness of the protecting layer 17 is made into a value equal to or below that of the magnetic layer 16, for the abrasion generated due to the sliding of a recording medium, the abrasion quantities of the protecting layer 17 and magnetic layer 16 are made approximately equal, and consequently, the partial abrasion can be released. The layer is made into a successive changing layer in which the hardness is made equal to or below that of the magnetic layer 16 in the part of the protecting layer 17 near to the magnetic layer 16 and the hardness is gradually hardened as it is separated from the magnetic layer 16, and when the hardness of the part corresponding to a most outer layer side is sufficiently hardened, even a protecting plate 19 can be omitted.
