In processing fish, a ventral portion at the rear of the belly cavity of each fish, together with the rear under fin and its attachments, is cut off by making two converging cuts in the fish, i.e. a cut at each side of said ventral portion. The cuts may be, made by two rotating, circular knives 1 inclined at an acute angle to each other, Fig. 4. These knives may first slit open the belly cavity to the anus. Each fish is fed from, an outer guide 3 on to a guide channel comprising two pivoted, mutually inclined half-guides 2. The two half-guides are then swung apart, downwardly, e.g. when the leading end of the firsh contacts a feeler 5, to lower the fish on to the knives 1, Fig. 5 (not shown). The fish then passes on to a. saddle guide 4, Fig. 6, breaks contact with the feeler 5 and contacts a feeler 6, which initiates return of the half-guides 2 to their upper position.

A slide changing mechanism for a projector comprises (Fig. 4) a slide carrier bar manually slidable in a guide 14a in a direction perpendicular to the optical axis of the apparatus. The bar 14 has a step 15 which engages the trailing edge of the leading slide 16 of a stack of slides in the input guide 12, so that when the bar is moved inwardly the slide 16 is carried into the projector where it engages a chamfered edge 18 of a detent member 17 supported on a pair of parallel cantilever springs 19a, and displaces the detent member sideways against the action of the springs 19a so that it is able to pass.

The present Specification thus proposes the elimination from the time quantized video signal of pulses of less than a predetermined duration. The video pulses SD1, Fig. 5, top and bottom clipped and time quantized in units T H  in means 23, Fig. 4 (not shown) are fed to firstly a pulse selector 91, Fig. 6, which eliminates positive going pulses of duration less than nT H  and secondly to a pulse selector 92 which eliminates negative going pulses. The value of n (in this case 4) is determined in means 93. Selector 91 comprises an input p stage shift register receiving signal SD1 and shifted at rate 1/T H . The first stage is directly coupled to an AND gate 9120 and the 2 ... p stages are coupled via respective OR (+) gates. Means 93, comprising an n selector switch, AND ( x) gates and inverters ( - ), feeds 1 pulses to the OR gates of the n + 1, N + 2 ... p, stages . . . AND gate 9120 thus receives 1 signals at all its inputs and gives an output when the first n stages all have a 1 state. Such an output is fed to a p stage output shift register 911, directly to the first stage and via AND gates to the remaining stages. Means 93 feeds 1 pulses to stages 2, 3 ... n such that the first n stages of registers 911 and all have a 1 state. The register thus gives an output signal SD2, delayed from SD1 by pT H . Signal SD2 is inverted to SD3 and fed to the second selector 92.
