Patent GB-747973-A (GB)
Abstract: 747,973. Calculating apparatus. POPPER, O. Aug. 24, 1953 [Aug. 25, 1952; Feb. 23,1953], No. 23346/53. Class 106 (1). A device for determining the fertile periods of women relative to the menstrual period comprises three relatively adjustable strips A, B and C, adapted to be permanently attached together, as by adhesive, in the adjusted position to give the desired information. For each month of the year there is provided a calendar strip C on which is marked in equal divisions the days of the month and of one half of the preceding and following months. Strip A has 36 divisions of the same size as those on strip C, the total length corresponding to the maximum length of the menstrual cycle and the first day being marked X. Strip B is divided into the same sized divisions as the other strips and has an indicating arrow g and, spaced from the arrow by a number of days according to the underlying theory, a shaded area a, a<SP>1</SP> indicating the fertile period. In use, the mark X on strip A is placed opposite the date on the strip C corresponding to the commencement of the last menstrual period. Strip B is then placed so that the arrow g is opposite the number corresponding to the user's average menstrual cycle. The shaded area a, a<SP>1</SP> then spans the dates on the strip C corresponding to the fertile period, and the arrow g lies above the date of onset of the next menstrual period. The supplementary shaded area d<SP>1</SP>, a<SP>1</SP> may be used in cases of fluctuating lengths of menstrual cycle. The strips may be bound as a booklet in which each alternate page comprises the strips A and B joined together by perforations and having the backs gummed, thus enabling them to be removed and stuck on the desired positions on the other alternate pages which consist of the appropriate sheets C for each month. In a modification, Fig. 5, not shown, only two separable strips B and C are provided, as the cycle scale A is printed diagonalwise on the strip C, thus allowing strip B to be applied in the appropriate position relative to scales A and C.

Title: Extracting phospholipids from animal organs
IPC: A61K35/12
Filed: 1978-07-18
Abstract: Phospholipid compositions are obtained from ground. homogenised animal organs by a four stage process. in the first stage the organs are soaked in acetone to sever bonds between phospholipids and other substances present in the organ. In the second stage, the organs are refluxed in acetone to remove extraneous matter such as proteins and amino acids. In the third stage, the phospholipids are extracted with ethanol. The acetone solutions, which may contain small amounts of entrained phospholipids, and the ethanol solution are all evaporated to dryness and the residues are taken up in diethyl ether. In the fourth stage the phospholipids are precipitated by addition of acetone. The phospholipid compositions obtained are of sufficient purity for pharmaceutical use.

Patent GB-2033608-A (GB)
Title: Cutting by a wire electrode
IPC: B23H7/06
Filed: 1978-11-01
Abstract: A wire electrode 1 cuts a workpiece 3 by electro-erosive or electro- chemical means. The cutting portion of the electrode tends to trail behind the mounting clamps 2 and may introduce errors between the actual cutting path and the desired path. The angle between these paths is evaluated and when it exceeds a predetermined value the direction of movement of the electrode is reversed until the trail is removed. The electrode then continues its forward movement and cutting is resumed from the point where it was left off. The cyclic reciprocatory movement of the wire to remove the trailing error is effected by apparatus including a computer 6 controlling feed motors through a controller 10 causing relative movement between the workpiece 3 and the wire electrode 1. A device 5 senses the voltage and current at the work gap 31 and controls the feedspeed. Deterioration of the erosive pulses in the work gap, through an OR-gate 8, causes a store 9 to effect a backward movement of the wire; the operation of computer being inhibited. <IMAGE>

Patent GB-785432-A (GB)
IPC: F42B30/14
Abstract: 785,432. Whaling projectiles. AIR WHALING, Ltd., and BRISTOW, A. E. Jan. 11, 1955, No. 799/55. Class 9(1) A projectile for injecting gas into whales as in Specification 785,431 has means for electrocuting the whales. The gas cylinder 1 is mounted between a penetration head 2 and a support 3 for the tail 4. Extending through the cylinder is a tube 5 with threaded ends screwed into the head 2 and a saddle 6 mounted in the support, the head 2, tube 5 and saddle 6 being of metal and the support 3 of electrically insulating material. The legs 12 of a stirrup 13 are pivotally secured to projections of extending transversely from the saddle 6. The legs of tubular metal wrapped in insulating material such as fibre glass end in metal lugs 14 apertured to receive bolts 11. Each lug 14 has a conical surface seated in a conical recess 15 to make good electric contact with the saddle, and a spring washer 16 surrounding the bolt holds the lug in the recess. From a metal bridge 17 joining the legs extends a hollow boss 18 on to which is screwed a nut 19 to secure an electric cable 20 to the stirrup, Fig. 5. The cable has a rubber core 21 on which is braided a conductor 22 covered by a rubber sheath 23, which is in turn covered with a braided cotton layer 24 and an outer braided or otherwise woven cover 25 of nylon or strong yarn. To connect the cable to the stirrup, the exposed conductor 22 is inserted in the tapered bore 26 of a metal plug 27 within the boss 18 and the flared end of the rubber sheath 23 is gripped between apertured members 29, 30 so that by tightening the nut 19 over tapered grips 28 engaging the outer cover 25 a watertight seal is formed. The conductor is thus connected through the plug 27; stirrup 13, lugs 14, saddle 6 and the tube 5 to the head 2, so that on penetration a shock is imparted to the whale by a source of current connected to the conductor. In a modification, insulated electric conductors may be housed in the stirrup and connected to the lugs 14.

Patent GB-2074708-A (GB)
Title: Heat treatment of ceramic products
IPC: F27B9/24
Filed: 1981-04-23
Abstract: In a tunnel kiln wet shaped articles 2 arranged in vertical layers and horizontal rows travel from left to right through drying zone 6 and pre-heating zone 5 to firing zone 4. They then return in the opposite direction, and are cooled by the transfer of heat to the incoming articles. Alternate conveying rollers 3 rotate in opposite directions and each roller has a varying diameter to contact only the articles which are to be driven in the corresponding direction. Each article is transferred laterally at the end of the firing zone to engage with the rollers rotating in the opposite sense. Hot and cold articles travelling in opposite directions thus alternate in the horizontal plane as well as in the vertical plane. In an alternative arrangement the firing zone is at the centre and wet articles travel from both ends of the tunnel and emerge from the opposite end after cooling. <IMAGE>
