Title: Improvements in or relating to hobs
Inventor: GOSTELOW BENJAMIN FRANK
IPC: F24C3/12
Filed: 1986-06-20
Abstract: A hob having a lid includes a safety switch/valve 11 operable by the lid to terminate the supply of gas/electricity to the hob taps/switches (13) as the lid is closed and, provided that all of the hob taps/switches are in the "OFF" position, to restore that supply when the lid is opened. In the event that at least one hob tap/switch 13 is not in its "OFF" position when the lid is closed, the safety valve/switch 11 is latched by a latching mechanism and held closed when the lid is next opened. To restore the supply, all the hob taps/switches must be returned to the "OFF" position. That action releases the latching mechanism and allows the safety valve/switch to restore the supply when the lid is open. The hob may be a separate unit or it may be part of a cooker. <IMAGE>

Title: Producing thermoplastic parts having a structure on their surface
Inventor: EHRENSTEIN DR ING PROF G W
IPC: B29C59/02
Filed: 1987-02-23
Abstract: In a process for making a rod-like part of thermoplastics material having a profiled surface, for example a gripper rod with a toothed profile as used in a shuttleless loom, heated synthetic resin (3) is introduced into a master mould comprising a matrix (1) and a plug (2) by an injection operation. Formation of the profile and subsequent cooling of the moulded material (3) are carried out in the same matrix (1), using a profiled hobbing plug (2b) under pressure. The molecular chains which have already been oriented in the main direction of stress of the part during the injection operation are made to conform to the surface profile at the embossing stage of the process. This process results in a part having great rigidity and strength due to the increase in its intrinsic strength. <IMAGE>

Title: Capacitive proximity sensor
Inventor: COLEMAN PAUL
IPC: G08B13/26
Filed: 1987-04-24
Abstract: A loop (1) or strip (2) of conducting foil is attached to an object to be protected. The strip or loop is connected to one end of a high inductance coil (3), the other end being grounded. Another coil (5) of high inductance is wound co-axially of coil (3). Coil (5) is connected via a diode (6) to an oscillator (7) operating at about 80 KHz. The oscillator output is coupled to a means which produces a signal which is frequency modulated (FM) by proximity of e.g. an intruder to the protected object. Intruder induced frequency variations tend to fall within a fixed frequency band, and thus can be distinguished from variations induced by other causes. The intruder induced variations are detected by using a band-pass frequency discriminating amplifier (10) and a comparator (11) which triggers (14) an alarm (13). The high inductance coils and use of FM reduce interference.
