Title: Soft material-cutting apparatus
Inventor: TONE HIDEO
IPC: B26D1/06
Filed: 1988-09-22
Abstract: An apparatus for cutting soft sheetlike material, such as a fabric material which is subject to elongation due to the effect of tensile force has a pneumatically-actuated gripper feed device 26 for supplying the material 16 which may be layered from an upper position to a lower position preferably in an intermittent step-like manner. A cutting device 36, including blades (62, 64, 66, Fig 7), act on the material, when in a stationary vertically-suspended condition, to form cutting lines (S1, S2, Fig 6) of basic configuration therein along the elongate direction thereof. The cutting lines may be repeatedly formed following each advancing step of the material 16 to create cutting lines which extend substantially continuously along the material. Devices are also provided for removing unwanted portions (N1, N2, Fig 6) of the material 16 so as to leave only the essential portion (M). The material, forming the portion M, which may consist of superimposed sheets 12 of flexible soft material which is subject to elongation by tensile force and thin flexible backing layer(s) 14, are separated at 43 and independently wound. <IMAGE>

Title: Noise suppression in gas turbine engine
Inventor: SMITH ANTHONY GREGORY
IPC: F02K1/34
Filed: 1990-08-30
Abstract: A gas turbine engine noise suppression system utilises a separate primary supply of gas from an aircraft auxiliary power unit which is ducted over the main aircraft engine cowling 3 to an annular chamber 4 before exiting via slot 5 and flowing over a Coanda surface 6 to mix rapidly and entrain a secondary flow of ambient gas. The mixed primary and secondary flows are made to form a co-flowing stream with main engine exhaust flow at the engine nozzle exit plane 8. The system negates the requirement to redirect flow from the engine in order to entrain secondary air. <IMAGE>

Title: Rupture initiation monitoring by acoustic emission
Inventor: YAMAGUCHI TAKURO
IPC: G01M13/02
Filed: 1991-03-28
Abstract: A method and apparatus is disclosed for monitoring rupture initiation in an article e.g. a gear wheel G, by investigation of associated elastic waves. While a load is applied to the article repetitively e.g. by a restrained wheel 14, the development of elastic waves in the article is monitored by means of an elastic wave sensor 16 which converts any sensed elastic waves into a corresponding electric signal. The electric signal is fed to a signal transmission device e.g. a slip ring 24 having the capacity of transmitting low-frequency components of the electric signal to a signal processor unit 40. The electric signal received at the signal processor is divided into successive signal segments which are averaged to produce an averaged signal waveform demonstrative of the presence of a rupture initiation in the article which may be a crack in a root portion of a gear tooth. <IMAGE>

Patent GB-2247770-A (GB)
Title: Nuclear reactors
Inventor: BROADLEY DONALD
IPC: G21C9/02
Filed: 1991-08-12
Abstract: In control rod insertion apparatus for a nuclear reactor, one or more thermal expansion elements (54) are inserted between the control rod drive (47) and the control rod, so that in the event of an excessive increase in reactor coolant temperature the control rod is moved into the core independently of operation of the drive. Excessive expansion of the elements may be arranged to cause unlatching of a control rod holder (59) from the drive, so that the control rod is free to fall into the core, but if fall of the rod into the core is impeded, the elements then push the rod into the core. Alternatively (figure 1), expansion of the elements may simply move the rod relative to the drive into the core. Various forms of expansion element are described (figures 2 to 7). <IMAGE>
