Patent GB-2101062-A (GB)
Title: Article transfer apparatus
Inventor: BRITTAIN ANTHONY SIMEON
IPC: B65G47/10
Filed: 1981-07-02
Abstract: Articles such as packets P containing a snack food product are deposited randomly at two delivery stations DS1, DS2 by means of a twin-tube form, fill and seal machine 10, ready for transference to the input end of a conveyor 13 by means of respective transfer mechanisms. Each of these mechanisms is capable of transferring a packet P to either one of two locations A and B which are spaced apart transversely of the direction of travel 15 of the conveyor 13. A numerical control system controls the operation of the transfer mechanisms such that, irrespective of the order in which packets arrive at the delivery stations DS1 and DS2, the packets are deposited in the locations A and B in a predetermined sequence. Check-weighers 12 may be provided at intermediate locations IL1, IL2 between the delivery stations and the conveyor. <IMAGE>

Title: Firearm with Rotary Magazine
IPC: F41A9/02
Filed: 1981-07-10
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 arm 63, 64 serves to guide rounds through an inlet opening 73 in the magazine, 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 is locked to the magazine body. In this position, it obstructs further movement of the first-inserted round and thus prevent 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 ejection of spent cartridges is described. <IMAGE>

Title: Device for separating radiation beam components which issue from an optical fibre
Inventor: KOONEN ANTONIUS MARCELLUS JOZE
IPC: G02B6/293
Filed: 1982-09-03
Abstract: A device for separating radiation beam components of different wavelengths, which issue from an optical fibre by means of a reflection grating (13) and wavelength selective mirror (12) which permits beam components whose wavelengths are comparatively similar to be separated from each other and from those wavelengths substantially different therefrom. A wavelength-selective mirror (12) is arranged between the input optical fibre (10) and the reflection grating (13), which mirror reflects the radiation beams of wavelengths  lambda N+1 which are substantially different from the wavelengths  lambda 1... lambda N of a group of radiation beams of comparatively similar wavelength to an output fibre (20), via lens (15) and dichroic filter (14) which serves to suppress any radiation of wavelength  lambda 1... lambda N also reflected by mirror and transmits the radiation beams of comparatively similar (closely spaced) wavelength to the reflection grating 13 which reflects each wavelength at a different angle ( theta 1... theta N) and effects spatial separation of the constituent wavelengths which are then focused onto output fibres (1, 2...N) via lens (31). <IMAGE>
