Abstract: 978, 512. Wide angle abutments. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 22, 1962 [Jan. 25, 1961], No. 2233/62. Heading G2J. To increase the angle of field of an objective L0, three or more afocal systems, each consisting of a positive lens L4, L6, L8 ... and a negative lens L3, Ls, L7 ..., are disposed as the long conjugate side of the objective L0 with their axes parallel to the optical axis of the objective. The positive lenses may be integral as also may the negative lenses, the two lens units being mounted in a casing. This casing 18 may be pivoted to the objective end of a telescope 15 so that it may be moved into the light path when it is desired to increase the field of view. The lenses of each afocal system may be cylindrical so that the angle of view is increased in one direction only.

The segments are expanded by right and left handed screws 17<a>, 17b having squared portions 17 which carry arms 16 coupled by links 15 to an operating- sleeve 13, the endlong movement of which and of the parts 7, 8 is limited by a collar 21 secured to the shaft. The actuating-screws mate with nuts 18, which may be housed in recesses in enlarged portions 18<a> of the segments, and may be held axially by the engagement of pins 23 with annular grooves 24, worms 25 meshing with teeth 26 being provided for effecting adjustment of the segments, which are cut away at 22 to facilitate dismantling through the constricted opening of the drum 1. A plate 9 and disc-portion 2 of the member 1 constitute a supplementary friction clutch operated simultaneously with the expanding-clutch by cams 19 formed on the bosses of the arms 16, and positively disengaged by contact of the cams with hooks 20. The parts 7, 8, 9 are feathered to the shaft 5 by keys 10, 11. According to the Provisional Specification, the segments are connected to the plate by pivot pins, hinges, links, or their equivalent.

[Class 128.] In a condiment receptacle comprising a plain vessel 1 removably fitted in the lower part of a telescopic casing 5, 6 the upper part 6 of which is arranged to depress progressively a hollow piston-rod 4, the piston 3 consists of an annular elastic or compressible plunger of rubber or similar material having a bevelled outer edge. The piston is mounted between shoulders 4b on the rod 4 and is preferably reduced in thickness towards the centre. The two parts 5, 6 of the casing are preferably connected by a screw thread which may be enclosed in a smooth cover. The part 6 of the casing is provided with a reduced outer end 6c which bears on a tapered nozzle 4a formed on the piston-rod 4 or on a shoulder 4c formed on the nozzle. The nozzle is protected by a cap 11 provided with links 9 slotted at 8 to engage pins 7 on the part 6c, the links passing through slots 6d formed in a shoulder 6e on the casing. The slots 8 and pins 7 may be dispensed with, the links being bent inwardly or outwardly at the bottom to form stops which engage beneath the shoulder 6e. Owing to the flexibility and shape of the piston, when the casing is unscrewed slightly after use, the piston-rod recedes slightly thus causing a suction, and withdrawing any protruding condiment into the nozzle.
