Title: Rendering articles tamper evident
Inventor: HALL JOHN OWEN
IPC: B65D55/06
Filed: 1989-08-22
Abstract: A method of rendering tamper-evident an article having a closure 14 comprises locating a first portion over at least part of the closure and affixing a second portion to the first portion and a part of the article. In the preferred embodiment a closed sleeve 16 is placed over the end of a bottle 20 to completely surround the cap 14 and is heat shrunk into place. An adhesive label 18 is then stuck on to the body of the bottle and on to the sleeve 16 in order to hold the sleeve 16 in place and prevent it from coming off the end of the bottle and to prevent rotation of the sleeve relative to the bottle. The cap cannot be opened without breaking the adhesive label 18 or the closed sleeve 16. <IMAGE>

Title: Method of connecting a polymeric service pipe to a main
Inventor: STOVES DEREK
IPC: F16L55/179
Filed: 1990-05-01
Abstract: A polyethylene gas or water replacement pipe 18 is inserted through an existing metal pipe 14 and terminates in a connecting piece 80 having a lateral opening 82 within a fitting 12. There is no need to effect excavation to make a connection to a main 10 containing a polyethylene replacement main 16.

Title: Removing a meltable core from a moulded plastics article by immersion in a heated salt solution
Inventor: YARDLEY JAMES FRANK
IPC: B29C33/52
Filed: 1990-07-26
Abstract: The moulded article of plastics material which may contain an embedded metallic component, is formed about a core of a material which melts at a temperature below that of the plastics material. The core is removed by immersing the assembly of plastics material and core in a bath containing a heated salt solution, and this avoids undesirable heating of the metallic component that would otherwise also occur with induction heating of the core, or difficulties that arise when using heating oils. <IMAGE>

Patent GB-2238075-A (GB)
Title: "Combined panic exit and exterior access lock assembly"
Inventor: EVANS WALTER R
IPC: E05B65/10
Filed: 1990-09-05
Abstract: A combined panic exit and combination lock assembly for a security area door including a panic exit device on the door inner side and a high security combination lock (41) on the door outer side, wherein operation of a panic bar (11) from within the security area concurrently retracts both the latch system of the panic exit device and the lock bolt of the combination lock for egress from the security area. However, retraction of the panic exit latch system and of the lock bolt from outside the door requires independent unlocking operation of both the panic exit device and combination lock. A primary latch bolt (26) of the exit device is retracted by a rod member and main control link (22) and secondary outputs and associated secondary latch bolts are connected to bellcranks (31). One of the secondary outputs is connected to the combination lock bolt mechanism and its associated bellcrank is coupled by a lost motion linking system (48a, b, f) to the rod member so that retracting movement is allowed without relative motion to achieve concurrent retracting movement of the bolts and relative lost motion movement provides independent retraction of the lock bolt or the primary latch bolt (26) from outside the door. <IMAGE>

Patent GB-2269967-A (GB)
Title: Audio data compression
Inventor: CAMBRIDGE PHILIP
IPC: H04B1/66
Filed: 1992-08-22
Abstract: Audio data compression is achieved by filtering received audio data (2) into several frequency sub-bands (6(a)-(f)), each sub-band covering a fraction of the total audio bandwidth. The lowest range of sub-band frequencies (6(f)) is transform coded (10) to provide masking thresholds, and the remaining sub-bands (6(a)-(e)) time-domain coded (18) also to provide masking thresholds. The masking thresholds are then used to perform psychoacoustic masking. <IMAGE>

Title: Multi-level cache system
Inventor: B RAMAKRISHNA RAU
IPC: G06F12/0862
Filed: 1993-10-05
Abstract: A cache system 10 for buffering data transfers between a CPU 12 and main memory 13 has e.g. two levels of buffers 15, 16. Data may be transferred via the highest level buffer. At the second level, data is transferred between the highest level and the CPU if the data is present at the highest level. However, if the data is not present at the highest level, the data is transferred from the second level buffer without making copies of the data in the first level buffer. At the lowest level, data is transferred between the CPU and the highest level buffer in which it is found. If the data is not present in either buffer, the data is transferred directly between the CPU and main memory. A choice among three different load/store instruction pairs, made by a programmer and/or compiler, allows data likely to be used several times to be stored in buffer 15, data likely to be used only a few times to be stored in buffer 16, and data likely to be used only once to be accessed directly from main memory 13, thereby optimising cache use. Cache controller 20 may also implement different preload instructions, one for each level of the cache; and register-clear instructions. <IMAGE>
