Title: Coital timing device
IPC: G06C3/00
Filed: 1970-11-20
Abstract: 1300980 Calculating apparatus CAMBRIDGE RESEARCH & DEVELOPMENT GROUP 20 Nov 1970 [21 Nov 1969] 55369/70 Heading G4B A device for calculating the fertile period of a woman, from the predetermined shortest and longest menstural cycles, and indicating an optimum coitus schedule to maximize the chance of conception, comprises two relatively movable scales, the first scale 34 being divided up into calendar months and days, the second scale 42 having a series of longest cycle markings 54 associated with each different shortest cycle marking 52 and a coitus schedule indicator 46 divided up into coitus and coitus abstention increments (i.e. periods of time in which coitus is and is not recommended respectively) 48, 50, which are preferably of different colours, for each group of similar shortest cycle markings. An initial abstention increment 114 may also be provided. The relative positions of the schedule indicator and cycle markings are dependent on the numerical value of the shortest cycle. A start of cycle indicator 56 is also provided on the second scale. Associated with the second scale is a further stationary indicator (58), (Fig. 6, not shown) with coitus and coitus abstention indicators 62, 64 for increasing the length of the coitus schedule when the difference between the shortest and longest cycles is greater than 3 days. In a preferred embodiment the scales are provided on moving belts running between parallel spaced rollers located within a common housing (Figs. 1 to 3, not shown). The second belt is transparent and both belts are viewable through a window 24. To use the device the second scale 42 is aligned so that the desired shortest and longest cycle markings appear in windows 26, 28. The first, calendar, scale is then moved so that the first day of the menstral cycle is aligned with the indicator 56. The recommended coitus schedule for maximizing the chance of conception is indicated by the increments 48, 50, 62, 64 and 114. A slidable day of the week indicator (Fig. 7, not shown) may be provided as well as fixed markings 94, 96 on the window 24 to facilitate the determination of menstrual cycle lengths. The device may be provided with interior lumination powered by batteries, such as an electroluminescent panel, to assist the reading of the scales.

Abstract: 1,268,365. Welding by pressure. AEROPROJECTS Inc. 28 March, 1969 [29 March, 1968], No. 55806/68. Heading B3R. In ultrasonic welding, a non-powered anvil 10 performs excursions out of phase with those of the vibrating sonotrode. An ultrasonic welding machine, which may be as disclosed in U.S. Specification 2,946,119, comprises a transducer coupling system terminating in a resonant sonotrode. An anvil assembly for use, e.g. with such a machine, comprises anvil 10 having a resonant frequency which differs from that of the sonotrode, being either above or below the resonant frequency of the latter. Anvil 10, which has a hardened face 10a which may be brazed or screw-attached to the anvil, is attached-preferably by brazing-to a base ring 12 which is detachably secured to a flange 18a of a mass 18 received within a support member 24 for attachment to the welding machine adjacent the sonotrode (Fig. 1, not shown). Elastomeric gaskets and 0-rings 20, 22, 26 and 28 prevent metal-to-metal contact between the mass 18 and the member 24. The length of the anvil 10, including the face 10a, is determined from the equation where: L is the length, in inches, of the anvil. K is the radius of gyration and equals r/2 of the anvil, where r is its radius. # is the angular frequency of the welding machine. C o  is the velocity of sound in the anvil. α is one of the roots of the equation The diameter, d x , for anvils for use at any power level P x  is determined from the equation and the first four roots α 1  to α 4  yield practical values of the anvil length and are α 1  # S#/4; # 2  # 9#/4; α 3  # 13#/4; α 4  # 17#/4.
