Title: Improvements in or relating to jacquard mechanisms
Inventor: ASHWORTH JOSEPH
IPC: D03C3/24
Filed: 1964-12-18
Abstract: In a jacquard each needle is engaged by a member reciprocated in synchronism with the advance and return of the cylinder, whereby on the return stroke of the cylinder any needle that was displaced on the selection stroke will be positively returned to its original position.  The return member comprises a series of parallel bars (32, Fig. not shown) engaging lugs (33) or stops on the needles (22), and may be connected to the needle plate (13), to reciprocate therewith. Alternatively the return member may be connected to the cylinder reciprocating mechanism, or may be moved by other mechanism in synchronism with the cylinder.

Abstract: 1,151,629. Magnetic heads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 Nov., 1967 [18 Nov., 1966], No. 62000/67. Heading G5R. In a magnetic head in which the parts 3, 4, Fig. 1, of the core of the magnetic circuit or circuits are accommodated in halves 1, 2 of an insulating housing, and can be connected to a reference potential through a metal foil 7 forming the operational gap between the core parts, the foil extends from the gap to at least one side face of the halves of the housing, the side face having a recess 10 into which the foil 7 projects, and in which it is held, after assembling the halves of the housing, by an electrically-conductive fixing agent (e.g. silver), which facilitates the making of a connection to the reference potential. (The halves of the housing may be assembled by filling their interior space with a filler.) The conductive fixing agent may extend beyond the plane of the side face to make contact with the chassis of the apparatus directly, or through a metal bracket or screening housing, when the head is secured in place (the chassis being assumed to be at the reference potential). An alternative mounting assembly is shown in Fig. 3, where the head is disposed in a screening housing 16; a resilient plate 18 between the housing 16 and the side face 9 of the head has an arm 19 projecting into the recess 10 to contact the fixing agent. Alternatively, arm 19 may be a lug bent from housing 16. The position of the head gap relative to the apparatus may be adjusted by a support 17. Half 2 may have a recess in addition to the recess 10 shown in half 1; these arrangements may be repeated at the other end of the foil 7. The invention may be applied to a head having a plurality of gaps.

Abstract: 1,243,358. Tobacco smoke filters; tobacco composition. CHEMWAY FILTERS Inc. 4 Nov., 1968, No. 52247/68. Heading A2C. [Also in Divisions B1 and B2] A filter tip in a cigarette, or a filter in a tobacco pipe, comprises a mixture of mineral particles, such as scoria, slag, glass or obsidian, and absorbing material particles, such at diatomaceous earth or clay (many types exemplified), which may be loosely packed or bonded together by sugar, dextrin, starch or other innocuous carbohydrate. A pad of cellulose or cellulose acetate may be located downstream to act as a secondary filter. In a cigarette, the filter tip has a metal sheath which acts as a radiator, the relatively high thermal capacity of the mineral particles causing them to act as condensers for vapours in the smoke, their rough surfaces with many concavities trapping condensates and solids. A relatively cool smoke is provided. In addition, every shred of tobacco in the cigarette may have a coating of absorbent clay, the whole cigarette thus filtering the smoke passing therethrough.

Abstract: 1,150,177. Photo-electric exposure timers. PAVELLE Ltd. Dec.1 1967 [Dec.5, 1966], No. 54404/66. Heading G1A. [Also in Division G2] In an exposure timer for a photographic printer where the charging rate of a timing capacitor is controlled by a photo-detector, the photo-detector is periodically turned on and off and by varying the relative lengths of the on and off intervals the charging rate can be additionally controlled to take account of photographic factors. The control may be automatically made while the exposure is in progress. Two or more such timers can be used for colour printing. In Fig.4 a photo-resistor 1 is fed with a squarewave from generator 4 whose mark space ratio is adjustable and conducts every other half cycle due to diode 5 to charge timing capacitor 2 which eventually triggers thyratron 3. Instead of a photo-resistor a photo-emissive tube may be used which obviates the need for diode 5 Fig.1 (not shown). Instead of the generator 4 the photo-detector can be turned on and off by break contacts operated by a cam whose distance from the contacts is adjustable to vary the on and off periods Fig. 5 (not shown).

The control circuit for the hydraulic pump motor M includes a control box 44 which breaks the circuit in response to a voltage difference between the photo-cells 33, 34, produced when the light image I from the light filament 26 falls on the edge of a carton C on a pallet P. The photo-cells 33, 34 are arranged one above the other in the housing L so that when the light beam reaches the edge of an opening, as shown in Fig. 2b, the lower portion of the image I is reflected from the carton C and is focused by a lens, Figs. 4, 5 (not shown) on to the upper cell and the other portion of the image is not reflected. The voltage difference thereby produced between the cells actuates the control box 44 to break the motor circuit when the manual switch 43 is in position B. To stop the fork adjacent a selected one of a stack of pallets supporting cartons, the operator closes a switch 51 to light the lamp 26 when the fork is in the region of the selected pallet. Alternatively, the switch 51 may be closed initially, if the control box is provided with a dial D on which the operator sets the number of the selected pallet zone and which is connected to a stepping counter arranged to allow interruption of the motor circuit only when the predetermined number is reached.

In operation a relay 27 starts to deenergize when the main bending angle has been bent and causes a contact 57 to close. The closure of contact 57 allows the bending motor to remain activated by a relay 56 and causes a condenser 54 to be charged within a time dependent on the adjustment of a preselected potentiometer 53<SP>1</SP>, 53<SP>11</SP> or 53<SP>111</SP>.
